Difference between Hot Galvanized Steel Lattice Trench Cover

　　Gradually withdraw from the market. The toughness of the groove cover is low and the hardness depends on the thickness of the product. At present, the groove cover of the glass grid plate is a very thin product, and the price of the glass grid plate is very thin, high and fragile.

　　Hot-dip galvanized steel lattice plate groove cover (water groove cover) also improves the toughness, hardness and durability of groove cover. It also improves the corrosion resistance and impact resistance, greatly reduces the toughness, hardness and durability of groove cover. It also improves the corrosion resistance and impact resistance, and greatly reduces the production cost of groove cover.

　　Because it is not made of cast iron (cover and frame hinge connection, anti-theft, easy to open), so it is not easy to lose, can directly play the role of anti-theft. Therefore, the steel grille slot cover plate is practical and innovative, not only has significant economic benefits, but also has good social benefits.

　　Characteristics of groove cover plate: The groove cover plate is made of steel plate. It has modern shape, strong impact resistance and 83.3% leakage area. It is several times of cement hollow and cast iron cover. After hot galvanizing surface treatment, it has good corrosion resistance without maintenance and replacement. It has the incomparable advantages of cast iron groove cover and is easy to install. In order to ensure the strength of the bottom plate, it must be installed before the cover plate is installed. Pre-support shall be made for the cement floor or angle steel. The bottom of the groove cover shall be filled with cement mortar at the bottom of the groove cover. The groove cover plate of any shape and size can be made according to actual requirements
