This 4-Roll Machine Turns Flat Steel Into Perfect Cylinders. Steel Fabrication Mega Manufacturing

Discover how massive steel plates become perfectly curved shells and tower sections using advanced plate rolling and bending technology. This video takes you through safe overhead crane handling, precise positioning, and progressive multi-pass rolling on heavy-duty 3-roll and 4-roll machines—handling thick plates (like 56 mm) with controlled pressure for smooth, accurate curvature. You’ll also see modern pipe fabrication workflows: spiral pipe submerged arc welding (external + internal SAW), high-frequency welded tube forming and square tube reshaping, and precision pipe end prep on a Pipe Spool Master lathe. Finally, explore wind turbine tower manufacturing—from cutting and grinding plates to rolling, longitudinal welding, circumferential welding on turning rolls, inspection, and protective coating for offshore-ready durability.
