drainage grating

Drainage grating 1. High Intensity: It adopts macromolecule complex material and reinforcing steel bar by high temperature mould press at one time. Its highest inspect result is 54 tons, accord with Construction Department of Peoples Republic of China CJ/T211-2005 Criterion. 2. Beautiful Show Manhole cover external pattern has fine design; it can be made in many colors beautify the environment. 3. Light Weight It weight only 1/3 of cast-iron manhole cover, more expediently transport, install, and rush to repair, lighten the work intensity. 4. Burglarproof This kind of material has no recycle worth so it was burglarproof. At the same time it has locked construction design, it can make the goods in the well avoid stolen. Stop City Black Hole accident. 5. Climatic resistant It uses big molecular weight and chemical steady macromolecule complex material, adopts scientist prescription, advanced and perfect technique equipment. The product may be used in -50--+150. 6. High Precision Due to its high temperature mould press at one time there is smaller aperture between cover and its under. It gets over the problem of cast-iron and cement manhole cover run, jump, sound. It improves traffic ability and travel comfort. 7.
