無機合成復合井蓋。本復合井蓋是用新型高強無機合成材料和玻璃纖維復合制做。屬于中檔復合井蓋產品。

(1)它的固化速度比纖維混凝土快幾倍，8小時可脫模，若三班生產，24小時可脫模三次，模具用量雖比石塑多，但卻只有纖維混凝土復合井蓋的1/6左右，也可降低模具投資。

(2)其強度僅次于石塑復合井蓋。可承載40噸以上車輛。

(3)它的綜合性能介于石塑復合井蓋與混凝土復合井蓋之間，優于混凝土;可應用于對復合井蓋技術要求較高的場合。

(4)復合井蓋是最理想、較先進、是其他模具所不能比擬的。

(5)它最突出優點是不使用鋼骨架增強，而以玻纖復合增強，屬于GRC型產品。因此，它在目前鋼鐵不斷漲價的情況下，更有不受影響的優勢。

Inorganic synthetic composite covers. The covers are used synthetic materials and new high-strength inorganic glass fiber composite making. Covers are mid-range products.

(A) its curing speed several times faster than the fiber concrete, 8 hours to release, if the production of three shifts, the release times may be 24 hours, although the amount of more than Shisu die, but only a fiber reinforced concrete manhole cover / 6 so, it can reduce mold investment.

(2) the strength behind Shisu covers. Can carry 40 tons or more vehicles.

(3) its overall performance between Shisu covers and concrete covers, better than concrete; covers the technical requirements can be applied to higher places.

(4) composite covers are the best, more advanced, other molds can not be compared.

(5) It is not the most prominent advantages of using steel skeleton reinforced, and with glass fiber reinforced composites, are GRC products. Therefore, it is constantly in the current steel prices, more unaffected advantage.
