50*100mm 1st Gen Termite Proof B1 Fireproof WPC Square Tube

The 50*100mm 1st Gen Termite Proof B1 Fireproof WPC Square Tube is a high-strength extruded composite profile engineered specifically for modern architectural exterior sunshade louvers, interior/exterior partition screens, and landscape pergolas. Manufactured using classic 1st Generation homogeneous extrusion technology, it blends 60% refined wood flour, 30% modified high-density polyethylene (HDPE), and 10% eco-friendly functional additives—including fire retardants and inorganic anti-insect agents—under high-temperature twin-screw continuous extrusion.

Featuring a classic 50mm × 100mm golden rectangular cross-section and heavy-duty hollow core design, this WPC square tube delivers exceptional flexural strength and wind-load resistance while keeping overall weight manageable for high-elevation dry-hanging and ceiling installations. Encapsulated fully by the HDPE polymer matrix, it achieves 100% termite proof protection and complies with B1 fireproof standards, completely overcoming raw timber defects like flammability, pest damage, moisture rot, and continuous painting maintenance.

• 100% Termite Proof Biological Protection: Encapsulates micro wood fibers deep inside the modified polymer matrix, completely cutting off the food supply for termites and wood-boring insects without needing toxic chemical treatments.
• Engineering-Grade B1 Fireproof Safety Performance: Compounded with halogen-free inorganic fire retardants, it rapidly forms a carbonized protective barrier when exposed to open flame. Self-extinguishes upon removal from fire, significantly reducing flame spread and meeting strict commercial building fire codes.
• Classic 1st Gen Homogeneous Profile: Utilizes proven 1st Gen extrusion technology with consistent material properties across its entire cross-section. Cutting, drilling, or beveling on-site will never expose mismatched inner layers.
• 50*100mm Golden Structural Geometry: The 100mm vertical depth provides an outstanding moment of inertia. Paired with a hollow core, it easily withstands heavy outdoor wind loads while reducing dead weight on support steel framing and building structures.

• Exterior Architectural Shading Louvers: Vertical and horizontal sunshade screens for commercial towers, office complexes, airports, and train stations.
• Landscape Pergolas & Trellis Beams: Main rafters, support beams, and cross-tubes for park pergolas, patio trellises, and resort pavilions.
• Interior & Exterior Space Partitions: Decorative privacy screens and feature wall louvers for hotel lobbies, restaurants, clubhouses, and private gardens.

Traditional timber and pressure-treated wood are vulnerable to pest damage because raw cellulose and lignin serve as natural food sources for termites. During high-temperature extrusion manufacturing, the modified HDPE polymer resin completely encapsulates every microscopic wood fiber in a 360-degree seal. Termites cannot chew through or digest the polymer layer, giving the product permanent, inherent termite protection from the core out.

Under rigorous fire safety testing, the product meets the national B1 Fireproof standard (equivalent to European EN 13501-1 Class B-s1, d0). Upon contact with open flame, fire-retardant agents inside the profile trigger an endothermic reaction that releases non-combustible gases to dilute oxygen and form a dense char layer. The self-extinguishing time is under 2 seconds, with minimal smoke toxicity and zero flaming droplets, fully satisfying strict fire safety compliance for large-scale public projects.

Because the product utilizes 1st Gen homogeneous technology, its material composition is solid and consistent throughout. Contractors can cut, drill, or shape edges on-site without exposing raw core material. The uniform 50mm × 100mm shape allows flexible installation using internal steel inserts or concealed aluminum brackets. Once installed, it will not rot, peel, or require painting, keeping maintenance costs near zero.

The 50mm × 100mm dimension is a highly standardized engineering shape, allowing the product to be tightly stacked and strapped on export pallets. The lightweight hollow core prevents container weight overloads while maximizing volumetric space inside a 40'HQ container, significantly reducing per-meter sea freight and landed costs for overseas importers.
