The grid grating, also known as the steel grating plate, is an iron - and - steel product made by cross - arranging flat steel at a certain spacing with crossbars (such as twisted square steel, square steel, round steel, flat steel, etc.) and welding them into a form with square grids in the middle. The steel grating plate is mainly used for making gutter cover plates, steel - structure platform plates, tread plates of steel ladders, etc. Generally, twisted square steel is used for the crossbars. The steel grating plate is generally made of carbon steel and hot - dip galvanized on the surface, which can prevent oxidation. It can also be made of stainless steel. The steel grating plate has the properties of ventilation, daylighting, heat dissipation, anti - slip, and anti - explosion.

Production Standards for Grid Gratings: (In China, the latest version of the steel grating standard in 2019) YB/T4001.1 - 2019 standard; In addition, the United States, the United Kingdom, Australia, and New Zealand also have their own respective standards. The steel standards are in accordance with GB700 - 88 and GB1220 - 92. Surface Treatment Methods for Grid Gratings: Hot - dip galvanizing, cold - galvanizing, spray painting, immersion in anti - rust oil, no treatment (generally, stainless - steel materials do not need treatment). Production standards for grid gratings in China include YB4001 - 1991 and YB/T4001 - 1998 standards. Grid gratings can also be produced in accordance with standards such as British BS4592 - 1 - 1995 and American ANSI/NAAMM (MBG531 - 88).
