Product Types & Applications
Longitudinally Welded Pipes
Straight seam welded pipes feature simple production processes with high efficiency and lower costs. Available in longitudinal submerged arc welding (LSAW) and electric resistance welding (ERW) variants, these pipes are ideal for smaller diameter applications where production speed is prioritized.
Spiral Welded Pipes (SSAW)
Spiral welded pipes offer superior strength compared to straight seam alternatives. They enable production of larger diameter pipes using narrower billets, making them cost-effective for high-pressure oil and gas transportation, pipe piles, and bridge construction.
Square Tubes
Our square and rectangular tubes are manufactured from rolled steel strip through precision forming and welding processes. Standard delivery lengths range from 4000mm to 12000mm, with wall thickness tolerances maintained within strict specifications.
Thick Walled Coiled Tubes
Thick walled coiled pipes are available in diameters from 400mm to 3000mm with wall thicknesses ranging from 4mm to 300mm. Custom lengths are available to meet specific project requirements.
