Grid plate standard
The National Development and Reform Commission issued the standard YB/T400 1. 1-2007. This standard not only specifies the appropriate size and structure of the grid plate, but also specifies the technical conditions of the grid plate, such as installation and design. The grating plate in this standard is suitable for public and private decoration and construction industries, as well as some chemical and light industries. Starting with the structure of grid plate, the standards of each structure are introduced one by one.
First of all, the grid plate can be made into different sizes and shapes according to the different needs of users. The number and spacing of the lower flat steel and the number and spacing of the upper cross bars can also be customized according to the needs of customers. However, there are requirements for wrapping. Although hemming is not required according to customer's needs, the cross-sectional area of hemming must be larger than that of flat steel. The length of welding seam must be greater than 4 times of the thickness of flat steel, and the height of solder joint should also be greater than the thickness of flat steel. When the edge is to bear the load, it cannot be welded at intervals. The wrapping is not load-bearing and can be welded at intervals, but the distance must be less than 1500mm.
Secondly, the number of teeth of flat steel should not be too small, which will weaken the anti-skid performance of flat steel. The standard stipulates that there should be a tooth profile every 2 cm. The bearing edge must be welded with each cross bar, and there is no gap or missing welding. If the grid plate is used on the platform, people often pass by or have loads, then the width of the plate should be greater than 300 mm, and the side plates should be welded without gaps.

The width can fluctuate up and down, and it is also 5 mm As mentioned above, the flat steel and the crossbar should be vertical, and the verticality should not be greater than 10%. The minimum deviation of crossbar position is 1mm, and the direct distance deviation of crossbar is 6mm. The above is the relevant content of the grid board standard, I hope to help everyone!
