Square well, square well cover, standard square well

Detailed description
The composite manhole cover does not contain metal, and the steel frame of the stone plastic manhole cover and concrete manhole cover is less than the total weight of the manhole cover. Not much steal value. And because the manhole cover is extremely strong, it is extremely difficult to remove this small piece of steel from the manhole cover. Therefore, thieves do not steal.
Inorganic magnesite composite manhole covers have high strength, low price and beautiful appearance. This product can be colored at will, and is easy to install, maintain and identify. Since it has no recycling value, it completely solves the problem of anti-theft. Our country will gradually switch to composite manhole covers in the next three to five years, and the market potential is huge
Inorganic synthetic composite manhole covers. This manhole cover is made of a new type of high-strength inorganic synthetic material and glass fiber composite. It is a mid-range manhole cover product.
Its strength is second only to stone plastic manhole covers. Can carry vehicles over 1 ton.
Its comprehensive performance is between that of stone plastic manhole covers and concrete manhole covers. It is better than concrete and can be used in situations with higher technical requirements for manhole covers.
Its most prominent advantage is that it does not use steel frame reinforcement, but is reinforced with glass fiber composite, which is a high-end product. Therefore, it has the advantage of not being affected by the current rising steel prices. Because it does not contain any iron, it is more theft-proof than stone plastic and fiber concrete manhole covers.
Its curing speed is several times faster than that of fiber concrete, and it can be demoulded in an hour. If it is produced in three shifts, it can be demoulded three times in an hour. Although the amount of mold is more than that of stone plastic, it is only about / or so that of fiber concrete manhole cover. Can reduce mold investment. With an annual output of 10,000 sets of manhole covers, only mold sets are needed.
Compound manhole covers are the most ideal and advanced molds that cannot be compared with other molds such as rubber molds, plastic molds, and fiberglass molds.
If you want to produce manhole covers with better performance and reduce mold investment, you should choose composite manhole covers
