Product Overview

Huangang SMC fiberglass manhole cover is heavy-duty anti-slip composite inspection access panel specially designed for municipal road sewer and sewage pipeline maintenance, produced in Henan, China by mature SMC sheet molding compound high-temperature compression molding technology. Long-cut fiberglass roving fully blended with anti-corrosion thermosetting resin is integrally pressed into a solid one-piece cover structure, internal reinforced rib layout greatly improves compressive and impact bearing capacity, capable of bearing pedestrian and light vehicle rolling without cracking or deformation. The top surface is molded with dense cross-shaped anti-slip raised texture, effectively preventing slipping hazards in rainy and wet road conditions. Standard size 500500mm is ready in stock, 600700mm and all round, square, rectangular dimensions fully customizable; mainstream grey and black color options for road engineering, all solid color matching available per customer requirement. Our factory supports full custom processing solutions: exclusive mold opening for non-standard sizes and shapes, precision punching for lifting holes, cable openings and pipeline reserved holes, eliminating secondary on-site cutting and modification. Different from cast iron and concrete manhole covers, SMC fiberglass composite material has natural anti-theft value (no recycling scrap value), permanent acid & alkali sewage corrosion resistance, light weight for easy handling, and no rust or noise when vehicles pass over. This manhole cover is standard supporting facility for urban municipal road drainage sewers, residential community sewage pipelines, chemical factory waste water inspection wells, park public drainage channels and all road maintenance engineering construction projects.
