樹脂井蓋之所以受到市場歡迎，是因為它具有其它井蓋產(chǎn)品無法相比的優(yōu)勢。首先，樹脂井蓋的承載能力好，這是由樹脂井蓋的內(nèi)部結(jié)構(gòu)決定的，因為樹脂井蓋的底部使用了特殊的鍋底型結(jié)構(gòu)，使它的受力面積增大了數(shù)十倍，另外，樹脂井蓋所采用的增強(qiáng)型纖維也從材質(zhì)上保證了產(chǎn)品的強(qiáng)度，使其具有非常優(yōu)異的負(fù)載能力。

其次，樹脂井蓋具有天然防盜功能，之所以這樣說，是因為樹脂井蓋采用不飽和樹脂為原料，不含金屬，基本無回收利用價值，所以有“賊不偷”的特點(diǎn)，這就有效解決了長期以來井蓋被盜的問題，保證了公共設(shè)施的完整和人車安全。

The reason being resin covers the market, because it covers the product can not be compared with other advantages. First, the carrying capacity of the resin covers the good, which is determined by the internal structure of the resin covers the decision, because the bottom of the resin covers the bottom of the pot using a special type of structure, so that it increases the force area several times, in addition, the resin covers the reinforcing fibers are used to ensure the strength of the product from the material, it has very excellent load capacity.

Secondly, the resin covers with natural anti-theft feature, say this is because the resin covers the use of unsaturated resin as raw material, non-metallic, almost no recycling value, so there are "thieves do not steal" feature, which is an effective solution for a long time the problem of stolen covers to ensure the integrity and security of public facilities and vehicles.
