Materials: SMC(Sheet Moulding Compound)a fibre-reinforced material. which consists primarily of thermoset resin, unsaturated and continuous non-alkali glass fibres and calcium, poly-styrene as fillers.which is to save other non-renewable resources.
1.Non-recycle value for anti-theft.
2.Acid, Alkali and Chemical corrosion, Impact resistant, and Anti-rust, weather-ability, insulating, durable (30years), Locking option. Anti-abrasion:fibreglass content above 28%,when demage,no holistic hole,avoid sudden accident.use the superfine calcium carbonate,good density.
3.Excellent anti-pressure capability: no hole on the surface and no damage of the unlock hole.uses the new raw material, the quality is stable.
4.Weight: just 1/3 of the cast iron one, and 1/2 of the BMC with steel one. Convenient for transport, security check, install,open and rush-repair to reduce work intensity.
5.Appearance: Physical appearance to be nice, smooth, good elastic curve, no distort, easy to open. the cover should not be sprayed on surface but the color must be homogeneous in mixing while casting. Unique multi-directional slip resistant tread pattern. Low noise and rebounding free when car roll on. Compass Range of composite access covers achieved a market leading Skid Resistance Value of 89,when tested by the Materials Laboratory of Devon Country Council
6.environmental protection, Energy saving: pollution-free, the entire process of producing no need massive heat energies, electrical energy and water resources
7.Perfect decoration effect: producing the color match the ground according to the customers demand
8.Carrying Ability:no steel, the load bearing capacity of the whole cover will be up to 25-60 Ton based on size. Complies with requirements of EN124:A15,B125,C250,D400
9. wafery edge design,can match the cast iron frame perfect,suit for old city rebuilding.
