In actual use, the use of steel gratings on steel platforms and steel ladders is often used as a stepping stairway. Therefore, such steel gratings are also called tread plates and stepped treads depending on the purpose. Because the tread board is often used at the connection of stairs, it is necessary to pay attention to possible problems during production and use, and to perform regular maintenance.


At present, there are four types of pedals commonly used in China, namely, ordinary type, protective type, plus side type, plus protective plate and side plate type. The specific parameters of some treads can be designed according to the drawings and actual use requirements.


The processing flow for the four stepping steel gratings is basically as follows:
1, single-sided fillet welding, welding height is not less than the thickness of flat steel bearing, weld length can not be less than 3.5 times the thickness of flat steel bearing, allowing four flat steel bearing interval, but the maximum interval should be ≤ 160mm.
2. The depth of the protection plate is "C", but it should not be lower than the load of flat steel. The recommended size of "a" (ie, the extension of the guard plate above the checker) is 100mm. Attached in the bearing span direction of the flat steel. In the length direction of welding flat steel, the protective plate should be welded with 3mm fillet welds. The welding length is 12mm per 300mm pitch. Attached to the end of the flat bearing steel.
When purchasing a steel grating tread plate, it is necessary to purchase according to the steel ladder or the use environment in combination with its own reality, and strive to purchase the steel grating tread plate that is most suitable for itself.
