Reinforced Plastic Manhole Covers

Reinforced Plastic Manhole Covers Product introduction-  Glass fiber reinforced plastic covers adopts unsaturated polyester resin as matrix of fiber reinforced thermosetting composite material, also called regiment shape mould plastic (DMC), with pressure molding technology is made, is a kind of new environment-friendly power cover plate. With high-temperature and high-pressure once moulding technology, the degree of polymerization, high density, good resistance to impact and tensile strength, have wear-resisting, corrosion resistant, rusty, non-pollution, free maintenance etc.   Product features Internal use mesh reinforced enhancement, key mechanical parts, special strengthen occurred in the inevitable external shocks, can quickly dispersed pressure guarantor car safety. Products: the optimal design of the stress of the posterior special skeleton, special strengthen key positions. Advanced structure, light weight, appearance generous, flawless, without delaminates, without bending deformation, prevent channeling move, safe in operation and convenient. High precision: this product bases, cover small clearances, occlusive close, overcoming the similar products running, jumping, ring, etc.    Applications (1) Electric power pipeling 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)As cover board for anti-corrosion project,open ditch;it as well as can be made according to customers requirements.   Part of the product size   BMC Products Manhole Cover Load Ability Approx Weight(KG) Diameter700 A15 17 B50 23.5 Flowerpot Manhole Cover dia700 A15 14       Rain-Grating Load Ability Approx Weighy(KG) 260*400*30 A15 1.8 300*400*30 A15 2 300*500*30 B50 2.8 450*750*50 B125 25       Tree-Grating Load Ability Approx Weight(KG) 200*200*30 A15 0.7  Rain-Grating     Size Load Ability Approx Weight(KG) 250*350*30 A15 9.25 300*420*30 A15 14.5 300*500*30 A15 15.5 360*420*30 A15 14.8 300*500*30 B50 23 350*350*30 B50 27 380*680*30 B50 31 400*420*30 B50 18.8 600*600*30 B50 30.2 450*750*30 C130 34.8 We can produce accoridng to your draws if there is no size listed above.
