Steel fiber concrete is developed in China in recent years a new type of concrete building materials, our factory according to its resistant to compression, bending, shear and strong advantages, combined with the reality of traditional cast iron covers, well grates easily stolen features, refer to the JC889-2001 JC/T3064-1999 national implementation of standards, developed different types of steel fiber reinforced concrete series of manhole covers, grates well received, well Shijing prefabricated neck. Continuously updated through the years, is now a new generation of prefabricated steel fiber reinforced concrete products. 
 The factory production of hybrid fiber reinforced concrete wells with, I plant a few years, scientific research development, the development of new products, products for the steel frame, and add a special fiber composite material, the forced mixing, vibration molding. This product uses the new materials, new technology, so that components of the compressive and flexural strength than ordinary cast iron well with, and has anti-theft, anti-corrosion, reduce noise and other functions, far more than the cast iron well with the quality standards. 
 Features 1, a small recovery value of the products can be stolen from the fundamental solution to the problem. 
 2, overloading occurs when a deformed broken covers the whole possible, but still love a certain load bearing bottom will not fall. Can effectively avoid the trap of property damage and road safety 
 3, according to user requirements of various text symbols, logos, embossing, etc., can also be made of colorful color covers. 
 4, reasonable design, build and perfect combination between the seat can reduce noise, reduce traffic bumps, beautify the environment. 
 Various types of products to adapt to the use of premises 
 First, the light. Meet green belt and motor vehicles can not travel and parking lanes, space, gardens, squares, lawns and other places. 
 Second, heavy. Adapt to the slow lane, residential areas and other local channels and sidewalk. 
 Third, increase the type. Main Road to adapt to road and other special roads and venues.
