Low Maintenance Requirements

High cost-effectiveness. 1/2 to 1/3 of wood cost & low maintenance requirements.

Strong Color Fixation And Dimension Stability Against Moisture And Temperature Changes.

Strong color fixation and dimension stability against moisture and temperature changes.

[Attached: Supplementary Information-Fireproof Material Grade]

Class A: Non-combustible building materials, materials that hardly burn.

Class B: Flame-retardant building materials: Flame-retardant materials have a good flame retardant effect. It is difficult to catch fire in the air or under the action of high temperature, and it is not easy to spread quickly, and the combustion stops immediately when the fire source is removed.

Class C: Flammable building materials: Flammable materials have a certain flame retardant effect. When exposed to an open flame in the air or under the action of high temperature, it will catch fire immediately, which will easily lead to the spread of fire, such as wooden pillars, wooden roof trusses, wooden beams, wooden stairs, etc.

General Information

Please contact us for the specification list.

Yes, we can, all of our samples are free, but the freight cost is owned to you.

You can choose the samples directly from our stock, or we can do the sample according to your required color design.

Yes, we can. We provide a large number of choices, but in order to meet more needs, we also provide customized services. Please contact us for more details.

Yes, our factory is located in Zhejiang Haining City, it covers 80000 square meters. We have 58 extrusion production lines. Now, we cooperate with wholesalers all over the world. Welcome to visit our office in Shanghai.

Composite wood decking costs more than traditional timber decking because of its higher cost of materials and manufacturing, also the cost of necessary chemical additives for stronger durability and longer usage.

Product Information

Our WPC products are made of 30% HDPE + 60% Wood Fibers + 10% Chemical Additives.

We apply the latest technology, but our price is favorable.

During the manufacturing process, our QC will check the size, color, surface, the quality, then they will get a piece of sample to do a mechanical property test. The quality will also be checked after treatment.

It is about 25-30 years under ideal situations.

It is recyclable which is friendly to the environment. It performs well in waterproof, moisture-proof, moth-proof, and weather-resistance, etc.

Customized Service

Generally, the length and color of products can be customized according to your requirements. If you have other specific requirements, the mold needs to be provided. You can order our free samples before you order for customization.

Yes, the following two conditions are required:

Material Area: 1000 total Square Meters

Lead time: 6 weeks


TT 30% deposit and 70% balance before shipment or against the B/L copy.

L/C at sight.

any other payment methods, please kindly remind in advance, it can be negotiated.

Delivery Information

Usually 10-15 days after receiving a 30% deposit for one 20ft container (nearly 850 square meters goods), this time can be reduced to 7 days if the order is regular, so that we could arrange the product works in advance.


Actually the installation is quite easy, both wall panel and decking, only require a simple tool like an electric drill, clips, and screws. You can finish the installation quickly, generally, 2 people are enough to complete about 50 square meters of wall panel/decking.


Wood plastic composite material performs well in weather resistance and UV resistance, but prolonged exposure will inevitably affect its color. Among wood-plastic composite decking, co-extruded composite decking is the best in terms of fade resistance.

As the difference with the wood, WPC products themselves own color, they don’t need extra painting. Generally, we provide 8 main colors as cedar, charcoal, chocolate, coffee, gray, light gray, redwood, wood. And also, we can make special color per your request.

Our composite products are low-maintenance, they do not need to be sealed, painted, or oiled regularly.

Compared to traditional wooden decking, composite decking requires little maintenance. Regular cleaning can keep longer tidiness and longer use. All you need for cleaning your decking area is a hard brush, soapy water, a bucket of warm water, airy space in warm and dry weather.
