Frequently Asked Questions

What makes seamless square steel tube different from welded square tube?

The main difference is the manufacturing structure. Seamless square tube is formed without welded joints, creating a continuous steel structure with improved integrity. Welded square tube is produced by forming steel plates or strips and joining the edges through welding. Seamless solutions are often selected for applications requiring stable structural performance and consistent mechanical properties.

Which material grade should be selected for structural applications?

The selection depends on project requirements, load conditions and fabrication needs. Q235B is commonly used for general structural applications due to its balanced performance and good processing characteristics. Q355B provides higher strength performance for projects requiring stronger load-bearing capability.

Can the steel tube be customized according to drawings?

Yes. Shunchen supports customized processing based on technical requirements, including cutting, drilling, bending and other secondary machining services. Customized solutions help match different equipment manufacturing and structural fabrication needs.

What surface treatment is suitable for outdoor applications?

For outdoor environments exposed to moisture or changing weather conditions, hot-dip galvanizing or customized anti-corrosion coating can provide additional protection. The appropriate surface solution depends on the working environment and expected service conditions.

Does Shunchen provide quality documents for export projects?

Yes. Shunchen can provide quality-related documents such as mill test certificates, inspection reports and mechanical performance records according to project requirements. These documents support technical evaluation and international project management.
