Calculate the price according to the galvanized flat steel interval and flat steel specifications stipulated by the state. The national standard galvanized grating is generally suitable for large and medium-sized factories and mines, and some construction sites with strict specifications.

Instead of standard galvanized grating, its production specification is an error of ± 5mm. Under the same size, it uses less raw materials than the national standard galvanized grating, and the general price is more cost-effective than the national standard.

National standard galvanized grating and non-standard galvanized grating are slightly different in spacing, resulting in differences in raw materials. National standards and non-standards refer to the spacing specifications of galvanized grilles, national standards (center distance) and non-standards (clear holes).

Center distance refers to: the center distance of galvanized flat steel is the distance from the center of two adjacent load-bearing galvanized flat steels to the middle of the center (it includes the thickness of a galvanized flat steel)

The center-to-center distance of the horizontal bars is the distance from the center of two adjacent horizontal bars to the middle of the center (it includes the thickness of a horizontal bar).

The grid plate has a certain corrosion resistance, and its insulation effect is also guaranteed. For many high-level users or chemical plants, its explosion-proof and flame-retardant effects are necessary, only in this way can better avoid dangerous situations.

Another thing to note is that there are many materials for making gratings, such as stainless steel, composite steel, or glass fiber reinforced plastic. Different materials are suitable for different places. If it is in a chemical place, stainless steel should be used, which can have better explosion-proof and flame-retardant effects.
