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,

Marine grade rectangular hollow section (RHS) refers to 316 stainless steel rectangular tubing specifically designed for applications in coastal, offshore, and marine environments where standard 304 stainless steel would be susceptible to pitting and corrosion from chloride exposure. The addition of 2-3% molybdenum to the 316 grade provides significantly enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking in seawater, salt spray, and chloride-rich
