Introduction of Black Square Tube
Black steel pipe Use: Widely used in building structure, machinery manufacturing, bridge construction, pipeline engineering and other fields.
Processing technology: produced by welding or seamless process. Welded black square steel pipe is made by bending and welding the steel plate; seamless black square steel pipe is made by piercing and other complex processes, which is suitable for high-pressure environment.
Advantages
High strength: due to the characteristics of its material and manufacturing process, black square steel pipe can withstand high pressure and tension, suitable for load-bearing structures.
Good plasticity: easy to cut, weld and mold, convenient for construction operations.
Cost-effective: compared with stainless steel pipe or galvanized steel pipe, black square steel pipe is less costly and cost-effective.
Variety of sizes: different specifications and sizes can be customized to meet various applications.
Aesthetically pleasing appearance: square or rectangular design makes the overall effect after installation more neat and beautiful, especially suitable for modern architectural design.

The main advantages of welded carbon steel pipe include:
1. Higher hardness and better wear resistance can be obtained after heat treatment.
2. The hardness in the annealed state is very moderate, and it has good machinability.
3. Raw materials are common, easy to obtain, and the production cost is relatively low.
4. Very strong and earthquake-resistant, it is a popular choice for construction, plumbing and supporting modern roads.
5. Safe, can be safely handled and used, is a good material for building houses that can withstand fires, hurricanes, tornadoes and earthquakes.
6. Easy to recycle and environmentally friendly.
7. For many uses, such as piping, carbon steel can be made very thin and cost-effective compared to other metals.
