What are the precautions for using H-beams?
When flame-cutting H-beams, the web should be cut first, followed by the flange section (from thin to thick), as stress can cause cracking. Preheating treatment with the cutting flame should be applied to the cutting area before cutting (preheating temperature ≥ 200℃).
When cutting and welding H-shaped steel and similar products, assign individuals with a valid qualification certificate in building steel structure welding to operate according to the relevant standards for building steel structures.
The cutting edges should be rounded off with a radius of not less than 25mm. After cutting, the cut area should be lightly struck with a welding chisel for stress relief.
H-section steel is commonly used as a load-bearing support in steel structures for industrial construction buildings.
At the event, the underground engineering was showcased as a support layout for steel piles and groups.
Industrial configuration and layout in the coal oil chemical and power sectors.
Can also serve as components for large-span steel bridges.
Ships, rigid manufacturing framework layout.
Trains, cars, and tractor beam supports.
