Product Overview

Huangang high quality SMC fiberglass manhole cover is heavy-duty square drainage channel access panel with customizable logo marking, designed for municipal road sewage and drainage well sealing, produced in Henan, China by mature SMC sheet molding compound integrated hot pressing technology. Long-strand fiberglass fully blended with anti-aging thermosetting resin is pressed into one-piece solid cover with built-in reinforced rib framework, greatly boosting compressive and impact resistance to withstand long-term light vehicle rolling without deformation or fracture. The top surface is molded with dense cross-shaped anti-slip raised grain to prevent slipping in rainy wet road conditions, two built-in metal lifting ring handles for convenient maintenance opening. The cover surface reserves dedicated logo embossing zones, we can customize customer brand names, pipeline type text, warning slogans and project trademarks via mold modification. Standard 500500mm square size ready for shipment, popular 700700mm specification and all square/round rectangular sizes adjustable, black as standard color with grey, green, blue and other custom colors available. Our factory offers full one-stop custom processing: exclusive mold opening for non-standard well frames, precision punching for lifting holes, cable through holes and identification slots, no secondary on-site cutting required. Unlike cast iron covers, SMC fiberglass composite has no scrap recycling value to effectively stop theft, resists acid-base sewage and underground soil corrosion, lightweight for easy manual handling and produces no metal clanging noise when vehicles pass. This manhole cover is standard supporting drainage facility for urban municipal roads, residential community drainage channels, chemical factory sewage inspection wells, park pedestrian road sewers and all municipal road maintenance construction projects.
