Long Description
We specialize in custom structural steel beam and column welding fabrication for construction and engineering projects, providing high-strength, high-stability load-bearing structural parts. Adopting national standard H-beam, I-beam, channel steel and angle steel profiles, we implement full penetration welding process in strict accordance with construction engineering welding standards, ensuring overall structural strength and load-bearing safety.
All structural steel beams and columns undergo strict raw material inspection, welding process control and finished product testing, with optional stress relief treatment to adapt to large-scale engineering construction scenarios such as building structures, factory buildings, bridges and port engineering. We provide professional anti-corrosion surface treatment, with strong weather resistance, suitable for long-term outdoor and harsh construction environments.
We support customized processing based on construction engineering drawings, including size cutting, welding assembly, hole position reservation and surface coating. With complete engineering qualification and quality certification, we provide material MTC, welding inspection reports and other complete documents to meet engineering acceptance requirements.
