Many welded bar gratings involve the determination of the load-bearing direction. Common welded bar gratings are made by cross-welding flat steel and twisted steel, and there are also those made by welding flat steel to flat steel, known as inserted gratings. The flat steel in the grating has the highest load-bearing capacity, so determining the direction of the flat steel is crucial for our grating products.
How to determine the load-bearing direction of flat steel in welded bar grating is generally determined by the welding of flat steel and twisted steel. When customers choose welded bar gratings, the purpose of the product and its application location are related to the load-bearing direction of flat steel.
Firstly, this is a very serious matter. Welded bar grating products are formed by welding load-bearing flat steel and crossbars (twisted steel) horizontally and vertically. In the dimensions, there is definitely a length of load-bearing flat steel and a length of crossbars. We must clarify these two data and cannot make mistakes. Some technicians may not understand and casually adjust these two data, which concerns us as manufacturers because we can provide suggestions, but we don’t know the actual usage, on-site conditions, or any special requirements at the construction site. We communicate continuously with customers in a responsible manner, with the sole purpose of serving the customer well and ensuring the product is installed successfully without any issues.
Generally, the load-bearing direction of welded bar grating is perpendicular to the steel structure supports. After installing two steel structure supports, when installing the welded bar grating, the two ends of the load-bearing flat steel are placed on the supports so that it can bear the load effectively.
The load-bearing direction of trench covers and stair tread plates is different. The size of the trench cover is 7001000, so 700 is the direction of load-bearing flat steel. The load-bearing flat steel direction of stair tread plates is in the length direction because people step forward on the tread, and the walking direction is usually opposite to the direction of the flat steel. For example, if the size of the stair tread plate is 800250, then 800 is the direction of load-bearing flat steel. Due to different usage scenarios, the load-bearing direction may vary.
This is to achieve better load-bearing. The flat steel direction of the trench cover is the width of the trench. On large platforms such as ordinary power plants, the direction of flat steel is between the steel beams.
