IX. FAQs
What are the main applications of S275MLH iron tubes?
Widely used in metal welded structures such as building steel structures, offshore platforms, and engineering machinery.
How do square tubes differ from other types of tubing?
Firstly, the cross-sectional shape of flat square pipes is rectangular or square. Compared to circular pipes, flat square pipes have a larger cross-sectional area and can withstand greater pressure and loads. This gives flat square pipes an advantage in some projects that require greater force, such as building structures, bridges, mechanical equipment, etc.
Secondly, the edges of the flat square tube are flat, with regular shapes on all four sides, making it easy to weld and connect. Compared with other pipes, the connection of flat square pipes is more convenient and fast, and can be achieved through various methods such as welding, threaded connection, flange connection, etc. This makes the flat square tube more flexible in engineering construction, saving time and costs.
Can yuantaiderun customize their steel products based on specific project requirements?
Yes, Yuantai Derun is one of the few manufacturers in China that can customize steel products.
