Histrong SPC stands for Stone Plastic Composite, a high-performance rigid wall panel made of 60%-80% limestone powder, PVC resin and eco stabilizers via one-step high-temperature extrusion. Compared with ordinary PVC panels, its dense solid core delivers higher hardness, stronger impact resistance and perfect dimensional stability without warping or layering. 

Our SPC panels pass SGS waterproof testing under ASTM C473-19. After 2-hour soaking, the water absorption rate reaches 0%, surface water absorption value 0.0g, fully mold-proof for bathrooms, kitchens and humid commercial spaces. It is formaldehyde-free, B1 flame retardant, with scratch-resistant UV coating and rich wood/marble textures. Click-lock installation cuts labor cost greatly. Same premium quality at factory direct prices, matching residential renovation, hotels, shops and offices. Contact us for bulk order cooperation.
