INOX STEEL INDIA is a leading manufacturer of Fabricated Welded Tubes designed specifically for projects where standard sizes, shapes, or alloys are not sufficient.
When engineers, OEMs, EPC contractors, and design consultants require custom OD, precision-shaped, or non-standard alloy tubes, INOX STEEL INDIA is chosen for multi-process welding capability, precision tolerances, and full customisation.
From 6 mm micro-tubing to 1200 mm custom OD fabricated sections, INOX STEEL INDIA supports both small-batch specialised requirements and long-run industrial production.
Fabricated Welded Tubes are custom-engineered tubular sections manufactured by welding sheets, strips, or profiled plates to create tubes with non-standard dimensions, shapes, or alloy combinations.
