Stainless Steel Pipe Profile

Stainless steel profile pipe is a product with a square, rectangular, or oval cross-section. It is made from steel grades alloyed with chromium, nickel, and molybdenum. The most common grades are AISI 201 and AISI 304. The profile shape provides high bending stiffness at a significantly lower weight compared to solid bars.

Economic efficiency:

Using profile pipes instead of round ones provides metal savings of up to 25% and significantly speeds up the assembly of metal structures.

Surface Finish Types:

»
Matte (2B) — for industrial and structural applications.
»
Mirror (BA) — decorative polished finish (600 GRIT).
»
Brushed (4N) — matte textured finish (180-320 GRIT).

Technical Parameters (TIG welding):

Parameter	Tolerance / Value
Wall thickness (S)	± 10.0% of nominal (1.0 — 3.0 mm)
Corner bend radius	External radius ≥ 1.5 * S
Perpendicularity	± 1%
Twist (torsion)	Max 1° per 1 meter of length
Straightness (deflection)	Max 2 mm per 1 meter of length

* Our company supplies pipes welded using the TIG method, ensuring maximum weld seam reliability.

FAQ

We supply stainless steel pipes with square and rectangular cross-sections. Wall thickness ranges from 1 to 3 mm. Standard pipe length is 6 meters, with custom cutting services available.

Our pipes are manufactured using TIG welding (Tungsten Inert Gas). This provides the cleanest and most durable weld, which remains virtually invisible after polishing and matches the strength of the base metal.

Stainless steel profile pipes are manufactured according to international quality standards ASTM A554.
