Inside ShengBang Steel’s workshop, every project carries its own story. Among them, this Ø300 mm, 6-meter-long black iron pipe stands out like a massive steel dragon brought to life through precision and craftsmanship.

The process begins with high-accuracy laser cutting, ensuring every opening and contour matches the engineering requirements. Due to its significant weight and length, the pipe is maneuvered using an overhead crane, allowing it to rotate and position steadily in mid-air. This provides the perfect working angle for each weld. Following positioning, the entire structure is joined with CO₂ welding, producing long, consistent, and beautifully formed weld beads along the curved 6-meter surface.

Such large-diameter pipes are commonly used for:
• Industrial exhaust and ventilation systems
• Outdoor structural columns
• Architectural industrial-style features
• Heavy-duty machinery pipelines
• Large-scale ducting and elevated platforms

Projects of this scale—large, heavy, and requiring extreme precision—are where ShengBang’s expertise shines. From laser cutting, rolling, welding, polishing, assembly, hoisting to inspection, every step is executed with the skill and discipline of true craftsmen.

To ShengBang, this is more than a 6-meter pipe; it is proof of capability, commitment, and craftsmanship.
