Galvanized steel grating (steel grating,hot-dip galvanizing grating )
is that flat steels and bars are welded by 200 tons of hydraulic resistance welding equipment in accordance with a certain distance, at the same time, arranged in cross, then welded into metal products with square lattices.
Flat steel space ,30-90 mm
Bar space ,30-100 mm.
Production standards
China , YB/T4001.1-2007 standards
Or, UK standard, BS4592-1-1995
USA standard , ANSI/NAAMM（MBG531-88）
Surface treatment
Hot-dip galvanizing, cold galvanizing, painting, dip rust oil, or ,do not deal
Superiority
a. Material savings: under the same load conditions,it is the best way of saving materials, accordingly, can reduce the supporting structure of the material.
b. Reduce investment: saving materials, labor, the provincial period, free cleaning and maintenance.
Applications
