SMC Roung Shape Diameter 700mm Composite Resin Manhole Cover

700 SMC composite material manhole cover, with lifting hole and adhesive tape, can replace the original cast iron manhole cover on the road without replacing the cast iron base, making the old municipal reconstruction more convenient and cost-effective. Our products have been exported to Europe and America, and have passed the test and approval of European independent lab. SMC manhole cover is made of sheet molding plastic, which has high strength through high temperature molding, and conforms to the GB / t23858-2009 executive standard of manhole cover industry. The sealant strip design plays the role of sealing and noise reduction. The stainless steel galvanized locking device is embedded to prevent the displacement of manhoel cover and the well water pouring back into the manhole cover in flood season, which will cause the black hole accident on the road surface. The non hole design also plays the role of sealing and water leakage, preventing the damage of lifting hole directly.
