1, product technical description
This series of manhole covers, water grates, water meter boxes and other products are high-strength W-SMC manhole covers developed by the company for 900KN. The product is made of high-strength W-SMC sheet molding compound (invention patent application No.2009 10095562.5) and formed into a high-density whole by high-temperature molding, which looks like an iron plate and has a hard texture. Now the products have been widely used in inspection wells such as electric power, telecommunications, mobile, gas pipelines and chemical bases, as well as real estate, urban trunk roads, high-grade highways, expressways, freight terminals, airports and other places.
This product has the characteristics of good impact resistance, bending strength, high wear resistance, high corrosion resistance, good breakage safety, anti-aging, anti-noise, bulletproof, beautiful and durable, light weight, convenient installation and moderate price. It is more technical and practical than similar products (such as cast iron, cement manhole cover, etc.). ), at the same time, there is no reuse value, which fundamentally solves the problem of theft. This product has been fully affirmed by the municipal departments of Zhejiang, Jiangsu, Anhui, Hubei, Henan, Jiangxi, Sichuan, Shanghai and other countries in Africa and Southeast Asia, and it is agreed that this product is the most ideal substitute for all road manhole covers!
