Product Description

The Architectural Stainless Steel Rectangular Tube is specifically designed for visible, aesthetically demanding applications in building and design projects. Manufactured from high-quality austenitic stainless steel, this tube combines structural integrity with superior surface finish options. Its clean lines, sharp corners, and polished surfaces provide a modern, sophisticated appearance that complements contemporary architecture. Unlike standard industrial tubing, architectural grades feature enhanced surface quality, tighter dimensional tolerances, and superior finish consistency.

    Precision 301 304 316 430 Cold Rolled Stainless Steel Strip 2B BA No.4 Finish
    Precision cold rolled stainless steel strip is a narrow, thin-gauge stainless steel product manufactured to significantly tighter thickness and width tolerances than standard cold-rolled sheet. Unlike standard sheet (typically 1000mm or 1219mm wide), precision strip is produced in narrow widths — usually less than 600mm — and thin gauges from 0.05mm up to 3.0mm. The key differentiator is the tolerance : the precision strip holds thickness variations to as low as ±0.005mm,
