Resin well cover is usually packed in bulk or with packing belt, which is mainly determined according to the requirements of customers. Packing is the most common packing method for rain grate, which is to bind the tree grate with rope. However, if it is a special-shaped rain grate, we suggest that you lock it with screws in order to stabilize it. Screw locking is to use four screw rods to fix through the hole diameter of the tree grate, which is relatively stable, and the composite well cover is not easy to slide, but it consumes a lot of time and materials. In a word, it is for the convenience of customers and the protection of the product during transportation.

Generally speaking, the traditional manhole covers have relatively high strength, high cost and certain recycling value, so many manhole covers are easy to be stolen. And the well cover in the next three to five years slowly use the composite well cover, in the anti-theft aspect, its market potential is huge. The strength and appearance of resin well cover are beautiful, so it can be colored at will, so it is more convenient for installation, maintenance and identification, so it has no recycling value In the next three to five years, it will be replaced with resin well cover, which has greater market potential. For it, the most outstanding thing is not the reinforcement of steel skeleton, and its glass fiber composite is also enhanced, so it is a GRC product, and it will not be affected even if the price of steel does not rise. At the same time, resin well cover does not contain any iron, so it has better anti-theft performance compared with stone plastic fiber concrete well cover. The comprehensive performance of resin well cover is between stone plastic well cover and concrete well cover. Compared with concrete, its performance is better. For such a thing, it can be applied to the occasions with higher technical requirements for well covers.

As far as we know, the application range of fiber reinforced materials in composite materials is relatively wide, and the dosage is relatively large. It also has the characteristics of small specific gravity, large specific strength and specific modulus. When we use carbon fiber or epoxy resin composite materials, the strength and specific modulus are several times higher than those of steel and aluminum alloy. At the same time, it also has good chemical properties, lubricity, heat resistance and fatigue resistance.
