Grating Standard:

Grating, like any other product, needs its own standards so that the product has the highest quality in all respects. Below, we have explained about the grating standard.

Standard grating lengths:

The most common standard dimensions of gratings are 1000 * 3000 and 1000 * 6000 mm, which for gratings with galvanized coating, these dimensions should not exceed 1000 * 3000 mm. Other dimensions and sizes can be made according to workshop drawings.

Due to the inevitable production errors in manual gratings, these gratings are usually not produced with a length of more than 1500 mm.

Standard grating widths:

Grating is produced as standard with widths according to the table. In order to maintain the order and integrity of the belts in terms of appearance and also no negative impact due to overtime on the gratings, it is recommended to use standard widths in the design of gratings.

Sample and standard layout: (According to DIN24537)

Layout of wide gratings Grids with a width of 1000 mm are used as standard. An example of this is drawn in the figure below. The open distance between two adjacent grating is considered to be between 6 and 10 mm.
