树脂井盖之所以受到市场欢迎，是因为它具有其它井盖产品无法相比的优势。首先，树脂井盖的承载能力好，这是由树脂井盖的内部结构决定的，因为树脂井盖的底部使用了特殊的锅底型结构，使它的受力面积增大了数十倍，另外，树脂井盖所采用的增强型纤维也从材质上保证了产品的强度，使其具有非常优异的负载能力。

其次，树脂井盖具有天然防盗功能，之所以这样说，是因为树脂井盖采用不饱和树脂为原料，不含金属，基本无回收利用价值，所以有“贼不偷”的特点，这就有效解决了长期以来井盖被盗的问题，保证了公共设施的完整和人车安全。

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.
