Manufactured in our 8,000m² facility using automated ERW (Electric Resistance Welding) technology, these square tubes feature uniform wall thickness distribution and excellent straightness. The production process involves continuous quality monitoring through ultrasonic testing and dimensional verification systems. Our steel sourcing follows international standards, with material traceability maintained throughout the supply chain.
Project benefits include reduced assembly time due to standardized connections, lower transportation costs through efficient nesting, and extended service life even in harsh environments. The square profile provides superior torsional resistance compared to round tubing, while the flat surfaces simplify bracket attachments and safety rail installations.
For specialized requirements, we offer value-added services including custom cutting to precise lengths, pre-drilled connection points, and protective coatings tailored to specific environmental conditions. All products undergo final inspection against ASTM A500 standards before shipment. Partner with our technical team to develop optimized solutions for your structural framework challenges.
