Satin brushed exterior with a square hollow profile.

Product Overview

Our 50x50mm stainless steel square tube features a directional satin brushed finish for visible metal components. Available wall thicknesses range from 1.2mm to 3.5mm, with material options including 201, 304 and 316 stainless steel.

Flat exterior faces make the square profile convenient for positioning and joining during fabrication. Specify the required material grade, wall thickness, length and finish before ordering so the supply matches your project requirements.

Technical Specifications

Size note: 50 x 50mm describes the outside dimensions. It is not identical to 2 x 2 inches (50.8 x 50.8mm). Photographs illustrate appearance; final specifications follow the confirmed order.

Satin Brushed Surface

The satin finish provides a fine directional texture and softer reflections for decorative metalwork. For orders requiring a consistent appearance across multiple components, please confirm the brushing direction, grit and reference sample before production.
