What is the WPC Profile 4×4 Heavy used for?

It’s used for structural outdoor and semi-outdoor builds such as durable louvers, pergola/canopy frames, strong railings, partitions, and heavy-duty furniture structures.

Can it be reinforced with steel inside?

Yes. This profile is designed so a steel square tube can pass through the inner cavity (depending on the selected steel size) to significantly increase structural strength.

Is it suitable for high-traffic or public areas?

Yes. Its high impact and pressure resistance makes it suitable for parks, public spaces, and high-traffic projects.

Is it suitable for outdoor weather?

Yes. It is resistant to UV exposure, moisture, and temperature changes, making it a reliable option outdoors.

Does it require painting or special maintenance?

No. WPC typically requires no painting or oiling. Regular cleaning with mild cleaners is usually enough.

Benefits of WPC Profile 4×4 Heavy

Very high resistance to pressure and impact: ideal for high-traffic projects such as parks and public areas.
Allows internal steel reinforcement: the internal cavity can accommodate a steel square tube to multiply structural strength.
Long service life in harsh conditions: resistant to moisture, UV exposure, decay, corrosion/rust-like damage, and pests.
Great for outdoor frames and posts: suitable for pergolas, canopies, louvers, railings, and strong partitions.
Low maintenance: no periodic painting or oiling, and reduced need for early replacement.
Aesthetic look with structural strength: can be supplied with surface finishes (e.g., embossed or sanded embossed) while maintaining high strength.
Eco-friendly: made from a wood-fiber + recycled plastic composite; recyclable and more sustainable.
