Stainless Rectangle Welded Tube

Stainless Welded Rectangular mechanical tubing is supplied according to ASTM A554 specifications cold worked unless otherwise. Most commonly available Grades these tubes supplied in are 304, 304-L, 316, 316L. Lean Duplex e.g W-NR 1.4162, 1.4062 supply is also available for supply from Europe. Some of the applications these rectangular & square tubing goes into are, construction industry, food & beverage, building & renovations, process machinary, offshore & marine industries, transport, architectural. Stainless corrosion resistance/self-healing properties, aesthetic elegance, hygenic features combined with higher strength with fire resistance compared to carbon steel, low maintenance, 100% recyclable, surface finish options, low temperature toughness, cold formability and long life cycle provides further advantage in all types of structures or applications.

Sizes: 10mm x 20mm to 200mm x 400mm.

Delivery: 30 - 90 Days Ex Production + Shipping. Specific accurate delivery lead-timings can be arranged - Refer sales office.
