Descriptions
LANDYOUNG FRP manhole cover is a composite material profile made of E-glassfiber, unsaturated polyester resin or vinyl resin by SMC process.
FRP manhole cover is a new type of manhole cover developed to solve the defects of steel and iron manhole covers that are easy to rust and lose, too heavy, and easy to be brittle, and to improve their use functions and economic and social benefits.
Advantage
Light weight, the weight of the glass steel manhole cover is only 1/4 of the iron cover, and the engineering installation and use of the opening and closing are light and flexible.
Good self-locking. The unique constrained connection structure of the glass fiber reinforced plastic round manhole cover and the well seat has a self-locking function to prevent the manhole cover from jumping off the well seat after the car passes by.
High strength, the tensile strength of FRP material is equivalent to that of Q235 steel, and the compressive strength is more than twice that of C30X. Its impact resistance, vibration, fatigue, and fracture resistance are better than steel, iron and other materials. It is used as a bearing structure of the manhole cover. Strength and safety conditions are easier to meet than iron manhole covers.
Anti-theft and loss, FRP products have no waste recycling value. Used as a manhole cover can avoid the hidden danger of steel manhole covers often being stolen and sold as scraps, thereby preventing traffic accidents caused by theft and loss of manhole covers, car falling or stuck in the well, and reducing owners Economic losses and accident liability.
Corrosion resistance, glass fiber reinforced plastic material is naturally corrosion resistant, used as a manhole cover for acid, alkali, salt, sewage and other corrosive medium environments, with technical and economic competitive advantages.
Application
FRP manhole covers are mainly used for municipal roads, water supply, power supply, post and telecommunications, street lamps, residential quarters, garden planning, oil and gas exploitation, chemical production, sewer covers, environmental sanitation and other projects.
Specification
1. Heavy-duty: roads or parking places where motor vehicles pass.
2. Light duty: green spaces, passages, bicycle lanes or sidewalks where motor vehicles are not allowed to enter.
3. Ordinary type: roads or parking places where cars of class 10 and below pass.
Various models and sizes can be produced according to customer requirements, and the length can be produced according to actual needs, and can be customized according to drawings and samples.
