China has become one of the most important sourcing markets for composite decking, WPC decking, and outdoor composite building materials. Chinese manufacturers now supply a wide range of decking solutions to distributors, importers, contractors, developers, landscaping companies, and building-material wholesalers around the world.

Compared with traditional timber decking, composite decking can offer a combination of wood-like appearance, lower maintenance requirements, weather resistance, and flexible design options. At the same time, the Chinese WPC industry has developed from conventional hollow decking boards into a much broader product category that includes solid decking, 3D embossed decking, co-extruded decking, ASA composite decking, fencing, cladding, railing systems, and customized outdoor products.

For international buyers, however, choosing a composite decking brand in China is not simply about finding the lowest factory price. Product consistency, production capacity, raw-material formulation, surface technology, quality control, customization, certifications, packaging, export experience, and technical support can all affect the success of a long-term purchasing program.

This article introduces five composite decking brands and manufacturers in China that are worth considering when sourcing WPC decking for international markets:

1. SolidexWood
2. LVSENWOOD
3. COOWIN
4. Seven Trust
5. AVID WPC

The order should be regarded as a practical buyer-oriented comparison rather than an official industry ranking. Each company has different strengths, and the best supplier for a particular project will depend on the buyer’s market, product requirements, budget, order volume, and customization needs.

1. SolidexWood

SolidexWood is a China-based composite decking and outdoor building-material brand focused on composite decking, composite cladding, ASA decking and cladding, fencing, timber tubes, and related outdoor products.

SolidexWood is particularly relevant for international B2B buyers looking for a supplier rather than simply a retail decking brand. Its product range covers both conventional WPC decking and newer-generation outdoor composite products, allowing distributors and project contractors to source several complementary products from one manufacturer.

According to SolidexWood’s published company information, its manufacturing base is located in Linyi City, Shandong Province, China. The company describes its manufacturing base as covering more than 200,000 square meters and having more than 200 employees, with production and logistics capabilities designed for international container orders.

• WPC co-extrusion decking
• ASA composite decking
• Composite cladding
• ASA cladding
• Composite fencing
• Timber tubes
• Outdoor accessories

Its product portfolio makes SolidexWood especially interesting for distributors that want to expand beyond standard decking boards.

For example, a distributor may initially purchase WPC decking but later add composite fencing and exterior cladding to the same product portfolio. This type of product integration can help importers build a more complete outdoor-materials offering.

SolidexWood’s current product range includes classic WPC decking and co-extrusion decking, while its ASA product line is positioned as a newer-generation outdoor solution. The company states that its composite decking combines natural wood aesthetics with the durability and sustainability characteristics expected from modern composite materials.

Why SolidexWood Is Worth Considering

One of SolidexWood’s major strengths is its emphasis on product development and outdoor composite technology.

The company states that it has a full-process quality-control system and that products undergo multiple quality inspections. It also lists certifications including ISO9001, ISO14001, CE, FSC, and BAL Green Label.

Its company history also dates the beginning of SolidexWood’s composite-material business to 2005. The company says it developed its own formulations and invested in composite-material production technology and equipment.

For B2B customers, another advantage is that SolidexWood provides more than manufacturing. Its published service information includes marketing support, graphic design, website development, exhibition design, and product training.

This can be valuable for overseas distributors that need help introducing a new decking product into their local market.

Best For

SolidexWood can be a suitable choice for:

• Composite decking distributors
• Building-material importers
• Landscaping contractors
• Outdoor-product wholesalers
• Hotel and resort projects
• Commercial landscaping projects
• Poolside and garden projects
• Buyers looking for ASA decking
• Buyers requiring customized decking and cladding

For buyers who want a long-term China supplier capable of providing both standard WPC products and newer-generation composite materials, SolidexWood deserves a place on the shortlist.

2. LVSENWOOD

LVSENWOOD is another established name in China’s WPC industry. The company, Shandong Lvsen Wood-Plastic Composite Co., Ltd., was established in 2006 and is based in Shandong.

Its product portfolio covers WPC decking, fencing, wall cladding, and other outdoor composite products.

LVSENWOOD reports an annual production capacity exceeding 50,000 tons, more than 60 production lines, over 100 profiles across seven major product series, and exports to more than 50 countries.

These figures make production scale one of the company’s major strengths.

Product and Manufacturing Capabilities

LVSENWOOD offers:

• Classic WPC decking

The company has also invested heavily in R&D and patented technologies. Its published information states that it has more than 30 intellectual-property rights, including invention and utility-model patents.

Another interesting aspect of LVSENWOOD is its focus on composite formulations and co-extrusion technology.

Its newer products use multi-layer construction designed to improve resistance to weather, water, corrosion, and aging. The manufacturer also describes the use of natural wood fiber and high-performance resin technologies in some product lines.

International Market Experience

For international buyers, LVSENWOOD’s export history is an important consideration.

The company reports that its products are sold in more than 50 countries. It also has experience supplying projects and customers in different climatic regions.

This matters because composite decking performance can vary depending on environmental conditions.

A product intended for a mild European climate may not have exactly the same requirements as decking installed in Australia, Southeast Asia, the Middle East, or other high-temperature and high-UV regions.

Therefore, buyers should ask manufacturers about:

• UV resistance
• Thermal expansion
• Moisture resistance
• Surface temperature
• Slip resistance
• Color stability
• Installation requirements
• Recommended joist spacing

rather than comparing suppliers based only on board price.

Best For

LVSENWOOD is particularly suitable for:

• Large importers
• WPC distributors
• Landscaping companies
• Commercial projects
• Buyers requiring large production capacity
• Buyers looking for multiple WPC profiles
• Projects requiring customized colors and sizes

Its combination of production scale, R&D investment, and international market experience makes LVSENWOOD one of the major Chinese manufacturers worth evaluating.

3. COOWIN

COOWIN is another established Chinese composite decking manufacturer with a long history in the WPC industry.

The company’s published information states that its WPC business began around 2000, while the COOWIN brand was established later as part of its international development strategy.

This long operating history gives COOWIN substantial experience in WPC formulation, manufacturing, product development, and international sales.

Its current product range demonstrates a strong emphasis on wood-grain appearance and outdoor architectural applications.

The manufacturer also emphasizes product development and production control. Its published factory information describes processes including raw-material mixing, granulation, extrusion, cooling and molding, sanding, brushing, cutting, cleaning, and packaging.

For an importer, understanding the manufacturing process is important because composite decking quality depends heavily on formulation and production consistency.

Material Formulation

COOWIN publishes information about its composite formulation, including wood fiber, HDPE resin, and functional additives such as UV stabilizers, anti-aging additives, and coupling agents.

This is important because “WPC decking” is not one standardized material.

Two boards can both be marketed as WPC decking while having very different formulations, densities, surface technologies, mechanical properties, and expected service performance.

For this reason, professional buyers should request technical data sheets and samples before placing large orders.

Quality and Certifications

COOWIN states that its manufacturing operations follow standardized quality-control procedures and that its products and production systems have been associated with certifications including ISO9001, SGS, and CE.

The company also states that its factory has more than 200 employees and an 18,000-square-meter manufacturing facility on one of its published factory pages.

For international B2B buyers, COOWIN is therefore worth considering when product development, manufacturing experience, and technical support are important factors.

Best For

COOWIN may be a good match for:

• International WPC distributors
• Landscaping contractors
• Commercial outdoor projects
• Architects and designers
• Importers looking for multiple composite products
• Buyers interested in co-extrusion decking
• Buyers looking for customized WPC solutions

Its long industry history and broad product portfolio make it a recognizable option within China’s composite decking supply chain.

4. Seven Trust

Seven Trust is a Shanghai-based WPC manufacturer that focuses on composite decking, outdoor wall cladding, fencing, DIY decking, and other wood-plastic composite products.

The company states that it was founded in 2008 and has developed a product structure covering multiple WPC categories.

• Board lengths
• Groove patterns
• Installation systems
• Packaging formats

A manufacturer capable of developing customized profiles can therefore provide greater flexibility than a supplier selling only standard models.

Global Distribution

Seven Trust’s claimed export reach of more than 100 countries is one of its most notable characteristics. Its published markets include countries in Europe, North America, Asia, the Middle East, and other regions.

This makes the brand worth considering for importers who prioritize international experience.

One of AVID WPC’s interesting advantages is its emphasis on product development.

The company states that it develops new molds regularly and can produce new profiles according to customer requirements.

For distributors, this can be useful when developing a private-label or exclusive product range.

Instead of competing directly with every other distributor selling the same standard decking board, an importer can work with a manufacturer to develop:

• Exclusive board profiles
• Custom colors
• Different surface textures
• Private-label packaging
• Customized accessories
• Project-specific dimensions

AVID WPC also lists certifications and testing credentials including ISO9001, ISO14001, ISO45001, CE, SGS, and other certifications on its product information.

How to Choose the Right Chinese Composite Decking Brand

The five manufacturers above all have different strengths. Therefore, the “best” composite decking brand depends on what the buyer is actually trying to achieve.

A distributor looking for the lowest initial purchase price may prioritize a different supplier from a hotel developer looking for premium co-extruded decking.

Before choosing a manufacturer, international buyers should evaluate at least seven areas.

1. Product Composition

Ask the supplier for the exact composition of the decking.

Important information can include:

• Wood fiber percentage
• Plastic type
• Virgin or recycled plastic
• Additives
• Surface-layer material
• Density
• Core structure

Do not compare two products simply because both are called “WPC decking.”

2. Surface Technology

Surface technology has a major effect on outdoor performance and appearance.

Common options include:

• Traditional brushed surfaces
• Embossed wood grain
• 3D embossing
• Co-extrusion
• ASA surface technology

If the project is located in a high-UV climate, the buyer should pay particular attention to UV resistance and color stability.

3. Production Capacity

Production capacity becomes important when purchasing containers regularly.

A supplier should be able to maintain:

• Stable production schedules
• Consistent product specifications
• Reliable packaging
• Sufficient raw materials
• Predictable lead times
• Consistent color batches

Large distributors should also ask whether the manufacturer’s stated capacity is dedicated to WPC decking or shared across many different products.

4. Quality Control

A professional composite decking supplier should have quality-control procedures covering the entire manufacturing process.

A buyer can ask for information about:

• Raw-material inspection
• Extrusion control
• Dimensional tolerance
• Surface inspection
• Color consistency
• Mechanical testing
• Water absorption
• Slip resistance
• UV/weathering tests
• Final inspection

Pre-shipment inspection is especially important for first-time orders.

5. Customization

If you are building a local brand, customization can become a major competitive advantage.

Ask whether the factory supports:

• Custom colors
• Custom dimensions
• Custom surface patterns
• Custom molds
• OEM packaging
• Private labeling
• Customized accessories

Not every WPC manufacturer has the same level of customization capability.

6. Installation Support

Composite decking is a system rather than simply a board.

A complete solution may include:

• Deck boards
• Joists
• Clips
• Screws
• Edge boards
• Starter clips
• Fascia
• Railings
• Installation tools

A supplier that can provide installation drawings and technical guidance can reduce problems during installation.

7. Export Experience

Finally, consider the manufacturer’s experience with your destination market.

Different markets can have different requirements related to:

• Fire performance
• Slip resistance
• Environmental standards
• UV exposure
• Structural requirements
• Packaging
• Customs documentation

An experienced export supplier may be able to identify these issues earlier in the purchasing process.

Comparison of the Top 5 Composite Decking Brands in China

The comparison should not be interpreted as a universal quality ranking. A supplier’s suitability depends heavily on the buyer’s requirements.

For example, a buyer searching for high-volume standard WPC decking may prioritize manufacturing capacity, while a private-label distributor may place more importance on customized molds and packaging.

Similarly, a project in a hot and high-UV climate may benefit from discussing co-extrusion or ASA decking options rather than choosing a conventional WPC board based solely on price.

Why Source Composite Decking From China?

China has developed a mature supply chain for composite outdoor building materials.

The country’s advantages include access to:

• Wood fiber
• Plastic resins
• Additives
• Extrusion equipment
• Surface-treatment technology
• Packaging suppliers
• Hardware manufacturers
• Logistics infrastructure

This integrated supply chain allows Chinese manufacturers to produce both standard and customized composite decking at different price levels.

For international buyers, another major advantage is the ability to source related outdoor products from the same supplier.

Instead of purchasing decking from one factory, fencing from another, and cladding from a third, buyers can sometimes consolidate several products with a single composite-material manufacturer.

This can simplify:

• Product development
• Quality control
• Packaging
• Documentation
• Container loading
• Shipping
• After-sales communication

However, buyers should still conduct due diligence before placing a large order.

A factory audit, product sample test, technical-document review, reference-project check, and pre-shipment inspection can all help reduce purchasing risk.

Final Thoughts: Which Chinese Composite Decking Brand Should You Choose?

China has no single composite decking manufacturer that is automatically the best choice for every buyer.

SolidexWood stands out for buyers interested in a combination of WPC decking, co-extrusion products, ASA outdoor solutions, composite cladding, fencing, and B2B product-development support. Its manufacturing base in Linyi, Shandong, combined with its focus on composite product development, makes it a strong option for distributors and project-oriented buyers.

LVSENWOOD is particularly notable for production capacity, product variety, and long-term experience in the Chinese WPC industry.

COOWIN offers extensive experience in WPC manufacturing and a broad range of decking, cladding, and fencing products.

Seven Trust is an option worth evaluating when international export experience and a broad WPC product portfolio are important purchasing criteria.

AVID WPC is particularly interesting for buyers looking for customized profiles, new molds, and a range of hollow, solid, embossed, and co-extruded decking solutions.

Ultimately, the right supplier should be selected based on product formulation, outdoor performance, production consistency, certifications, customization capability, MOQ, pricing, lead time, packaging, and after-sales support, rather than brand name alone.

For importers and distributors planning to build a long-term composite decking business, requesting samples from several Chinese manufacturers and comparing the actual boards side by side is often the most effective next step.

Frequently Asked Questions

What are the top composite decking brands in China?

Five manufacturers worth considering are SolidexWood, LVSENWOOD, COOWIN, Seven Trust, and AVID WPC. Each has different strengths in production scale, product development, customization, export experience, and composite technology.

Is Chinese composite decking suitable for international markets?

Yes. Chinese manufacturers supply WPC and composite decking to many international markets. However, buyers should evaluate the exact formulation, testing, certifications, and climate suitability of each product rather than assuming all Chinese decking products have the same performance.

What is the difference between traditional WPC decking and co-extrusion decking?

Traditional WPC decking generally has a composite structure throughout the board, while co-extruded decking adds a protective outer layer around the core. The additional surface layer can improve resistance to moisture, staining, weathering, and color fading, depending on the formulation and manufacturing process.

Is ASA decking better than regular WPC decking?

ASA decking is a newer composite outdoor solution designed to provide enhanced surface durability and weather resistance. Whether it is better depends on the project environment, budget, appearance requirements, and expected service conditions.

Ask about material composition, board dimensions, density, surface technology, UV resistance, water absorption, slip resistance, available colors, certifications, MOQ, production capacity, lead time, packaging, installation accessories, warranty, and customization options.

Can Chinese composite decking manufacturers provide OEM services?

Many Chinese manufacturers offer OEM, ODM, customized colors, profiles, molds, packaging, and private-label services. However, the exact customization capability and MOQ vary by factory, so buyers should confirm these details before ordering.

What is the best composite decking for commercial projects?

For commercial projects, buyers should focus on long-term weather resistance, dimensional stability, slip resistance, color stability, maintenance requirements, installation efficiency, and supplier consistency. Co-extruded or higher-performance composite products may be worth considering for demanding outdoor environments.

How can I compare composite decking suppliers in China?

The best approach is to request samples and technical information from several manufacturers, compare the boards physically, review factory and quality-control information, confirm certifications, and obtain a detailed quotation based on the same product specifications and delivery terms.

For buyers looking for a China composite decking supplier, SolidexWood can be considered alongside other established manufacturers when comparing product technology, customization, quality control, and long-term B2B cooperation.
