Product Description

Steel Grating is made by Carbon or mild steel of certain sizes through the processing of slit cutting, serration-making, press welding, inspecting before galvanization, galvanizing, checking before packing, etc.
Application:
Steel grating, designed scientifically and equisitely, is very strong and safe to support floors and walkways. It can be used for ceiling, interior and exterior decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.
Materials:
Mild carbon steel with a variety of grades; Also customerized steel.
Advantages:
Steel grating is of light weight, good strength, large carrying capacity and can save materials and cost. It offers good ventilation of light and wind, a modern sense, aesthetic appearance and anti-skid safety. It is also easy to clean, easy to installation and durable for uses.
Surface Treatment:
Steel grating untreated: Allowing quicker delivery to customers whom fabricate and galvanize the grating on their own.
