According to The Design Requirements of Galvanized Steel Composite Panel

Galvanized Steel Composite Panel has the characteristics of lightweight, convenient installation and disassembly, transparent ventilation, high bearing capacity, material saving, durability, safety and skid resistance, easy cleaning, beautiful appearance, etc. Galvanized steel composite panel is widely used in cement plant platforms, corridors, stairs and other places, and gradually become the trend of modern cement plant construction.

The production of galvanized steel composite panel shall meet the following requirements:

1. Galvanized steel composite panel are welded by single-sided fillet welding. Galvanized steel composite panel are allowed to weld one of four kinds of flat steel under pressure at intervals, but the spacing is not more than 180mm, under the condition that the composite plates are unloaded. Spacing and full welding. The weld height shall not be less than the thickness of the bearing steel, and the weld length shall not be less than 4 times the thickness of the bearing steel.

2. Galvanized steel composite panel determines the distance between bearing flat steel and beam according to design requirements. As an industrial platform, the spacing of bearing flat steel shall not exceed 40 mm. At the end of the loading flat steel, the edge of the loading flat steel and the flat steel with the same specification as the loading flat steel; Under special circumstances, the edge of the blanket is directly covered with steel or flange plates. Section area shall not be less than the load-bearing flat steel.

3. The end edge plate of the stair tread must be completely welded to one side. The edge plate of the stair tread must be welded to each horizontal bar in the direction of the bearing flat steel. If the galvanized steel composite panel has a leading-edge covered guard plate, it must run through the entire step.

4. Galvanized steel composite panel generally has three types of loading flat steel. Loading flat steel can have tooth shape to increase anti-skid force, with not less than 5 teeth per 100mm.

5. The cut or opening of galvanized steel composite panel is equal to or greater than 180mm and shall be wrapped.
