Standard Stainless Steel Grating is a corrosion-resistant flooring solution made from premium alloys such as ASTM A240, AISI 304, 316L, 310S, 201, SUS304, SUS316L, or SS304. It features rectangular or I-bar bearing bars (e.g., 25×3 mm to 100×10 mm; US standards: 1”×3/16” to 1 1/2”×1/4”) with pitches of 12.5–80 mm (e.g., 19-W-4, 15-W-4). Cross bars include round (φ6–φ12 mm) or twisted square steel, spaced at 38.1–120 mm (2”–4”). Available in plain/smooth or serrated styles, with untreated, polished, or painted finishes. Material Test Certificates (EN 10204 3.1) available on request.
