无机合成复合井盖。本复合井盖是用新型高强无机合成材料和玻璃纤维复合制做。属于中档复合井盖产品。

(1)它的固化速度比纤维混凝土快几倍，8小时可脱模，若三班生产，24小时可脱模三次，模具用量虽比石塑多，但却只有纤维混凝土复合井盖的1/6左右，也可降低模具投资。

(2)其强度仅次于石塑复合井盖。可承载40吨以上车辆。

(3)它的综合性能介于石塑复合井盖与混凝土复合井盖之间，优于混凝土;可应用于对复合井盖技术要求较高的场合。

(4)复合井盖是最理想、较先进、是其他模具所不能比拟的。

(5)它最突出优点是不使用钢骨架增强，而以玻纤复合增强，属于GRC型产品。因此，它在目前钢铁不断涨价的情况下，更有不受影响的优势。

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.
