Standard Steel Grating

Standard steel grating is usually made of carbon steel. The outer hot galvanizing can prevent oxidation. It can also be made of stainless steel. Steek grating has ventilation, lighting, heat dissipation, anti-skid, explosion and other properties. The steel grating surface can be punched to increase anti-skid performance. Flat steel can also be made of I-type flat steel.
Production standards:
China's YB4001-1991, YB/T4001-1998, YB/T4001.1-2007 standards (China is the latest version of the steel grille standard in 2007); in addition, the United States, Britain, Australia and New Zealand have their own standards, but also in accordance with the British BS4592-1-1995 and the United States ANSI/NAAMM (MBG531-88) standards. Steel standards are implemented according to GB700-88 and GB1220-92. .
Preparations: Inspection before installation; Steel grating in place in different areas; Temporary fixing; Deviation measurement; Deviation correction; Final fixing.
