Cold Rolled Steel Pipes

Product Overview: Our Cold Rolled Welded Steel Pipes are manufactured with exceptional precision, designed specifically for applications that demand rigorous dimensional accuracy and superior surface finishes. The cold rolling process provides a remarkably smooth, clean surface without scale, making these tubes the perfect foundation for advanced surface treatments such as electroplating, powder coating, and premium painting.

Backed by our extensive manufacturing capabilities and massive mold inventory, we supply global manufacturers, fabricators, and machinery producers with highly customizable, top-tier steel tubing solutions.

Available Materials & Steel Grades: To meet your specific engineering and processing requirements, our production lines are fully equipped to handle a comprehensive range of materials, including:

• Cold Rolled Series: Cold Rolled-, Full Hard / Cold Hard (冷硬), Cold Formed (冷成形)
• Annealed Series: Black Annealed (黑退), Bright Annealed (光亮), Medium Annealed (中退)
• Hot Rolled & Processed: Hot Rolled (热轧), Pickled & Oiled (酸洗)
• High Performance: High Tensile Steel (高涨力), Galvanized Steel (镀锌)
