Product Name: Steel Grating/Stair Tread/Drainage Cover Model NO.: gratings Material: Carbon Steel Manufacturing Method: Machine Welding Shape: I Shape Application: Steel Structure Walkway, Foot Pedal, Drain Cover Certification: CE, ISO Trademark: BEWIN Transport Package: Container Loading Specification: Wide: 2' to 3' Origin: China HS Code: 7308900000 Product Description Galvanized steel gratingis an ideal product for wet, slippery situation where corrosion resistance is vital. The mild steel gratings are hot dipped galvanized in the galvanizing bath. The galvanizing bath has got 7 tank surface cleaning process, the purity of the zinc used for hot dipped galvanizing shall be 99.95 % pure. The galvanized coating shall be as per IS-3202/IS-4759 / IS-2629/IS - 2633/IS-6745,ASTM -A -123 or equivalent to international standards. The appearance of surface is plain or serratedGalvanized steel gratingis widely used in most general industrial plants as well as commercial buildings, it has wide applications as walkways, platforms, safety barriers, drainage covers and ventilation grates. It is also ideal for use as mezzanine decking since it supports the same loads as comparable solid flooring. More than that, its cost saving openness maximizes the circulation of air, light, heat, water and sound, while promoting cleanliness.Material:carbon steelSurface treatment:hot-dipped galvanizedWidths:2'or 3'Lengths:20' or 24'Galvanized steel grating is available in: Grade 2 (Medium) or Grade 3 (Coarse)Available in light duty and heavy dutyAvailable in welded, press-locked, swaged lock or flush mount constructionFeatures:* Can be purchased in stock sizes or custom fabricated to meet the project specifications.* Excellent load bearing capabilities* Ventilation of air, light, sound* Don't collect Liquid and debris* Long service life* Wide range of open areas* Galvanized steel grating has an unmatched surface.
