Wuhu Senlai is a China-based manufacturer specializing in advanced Wood-Plastic Composite (WPC) products for commercial and residential projects worldwide. Our WPC products are formulated with recycled polymers and natural wood fibers, combining aesthetics, durability, and sustainability for outdoor architectural applications.
With modern production facilities and a focus on material innovation, we provide reliable manufacturing and stable supply for distributors, contractors, and project customers.Our products are supported by recognized quality, safety, and environmental certifications and testing, including CE, ISO 9001, ISO 14001, ASTM, GTS, and OTC.
Quantifiable production strengths driving consistent delivery for global B2B buyers
We partner with regional importers and brand distributors to deliver full-scope turnkey customization.
Support custom color matching via RAL codes or physical samples. Choice of deep 3D wood grain, brushed, sanded, or smooth finishes.
Custom extrusion dies and mold development. We engineer proprietary cross-sections, clip grooves, and interlocking joint systems.
Custom carton printing, laser-engraved branding on profile edges, customized length cutting, and pallet loading optimized for 20GP/40HQ containers.
Our standardized 7-stage manufacturing process guarantees high material density, structural integrity, and flawless surface grain across high-volume orders.
Rigid screening of grade-A HDPE polymers & ultra-fine natural wood fibers.
Automated precision blending with UV stabilizers, lubricants & antioxidants.
High-torque twin-screw extrusion to eliminate bubbles and internal stress.
Online thermo-embossing providing deep, natural 3D wood textures.
360° protective polymer capping layer for unmatched stain & scratch resistance.
Full-line dimensional, load bearing, and color variance checking.
Protective film, edge protectors & seaworthy pallet strapping for export.
How do we guarantee quality? We execute an in-house 6-tier lab testing protocol on every single production batch before dispatch.
Moisture content, melt flow index (MFI), and purity tests for all polymer chips and wood powder lots.
Hourly line audits checking wall thickness, dimensional tolerances (±0.5mm), and profile straightness.
Spectrophotometer analysis ensuring minimum Delta-E variance between different manufacturing batches.
Submersion testing to verify <1% water absorption rate, preventing swelling, rot, and mold growth.
Accelerated QUV weatherometer testing simulating 3,000+ hours of intense solar radiation to prevent fading.
Hydraulic flexural modulus testing ensuring optimal strength-to-weight ratio and deflection resistance.
