Main Features
1 light dead weight, glass fiber reinforced plastic covers weighs iron covering a quarter, engineering installation and use lightweight flexible opening and closing.
2 good self-locking, glass fiber reinforced plastic circular manhole covers and well unique constraint link structure, prevent the car seat covers jump from well after passing the self-locking function.
3 high strength, the tensile strength of glass fiber reinforced plastic material with Q235 steel and the compressive strength is twice as tall as C30X above, shock, vibration, fatigue and fracture performance is better than that of steel, iron and other materials, used as a bearing structure covers, strength safety conditions than iron manhole covers are more likely to meet.
4 anti-theft, glass fiber reinforced plastic products without recycling value, used as a manhole cover can avoid steel manhole covers are often steal scrap selling hidden trouble, so as to prevent stolen manhole cover loss caused by person, car fall into, or card in the borehole accidents, reduce the economic loss and accident liability of owner.
5 corrosion resistance, natural corrosion resistant glass fiber reinforced plastic materials, used as acid, alkali, salt, water and other corrosive medium environment covers, with technical, economic, competitive advantage.
Application
1. Electric power pipeline well; Post, telecommunication, communication pipeline well;
2. Street lamp well, fire control well, all kinds of valve well;
3. City water, drainage pipeline well; Heat supplied, gas well;
4. Anti-corrosion project, open ditch; It can be made according to customers requirements.
