Galvanized Steel Grating,American ANSI/NAAMM (MBG531-93) standard,British BS4592-1:1995 standard
Karola supplies various steel gratings mainly galvanized steel grating and stainless steel grating used as industrial flooring and anti-slippery tread plates.
Why Galvanized Steel Grating?
Steel Grating is made by Carbon or mild steel of certain sizes through the processing of grooving, lock-pressure, welding, finishing and other treatment. Industrial metal gratings can be actually made from copper, aluminum, stainless steel and other materials, while galvanized steel grating is the mostly used one due to its economic cost and good corrosion resistance. Steel gratings hot dipped galvanized make an better choice over non-galvanized steel bar grating due to the fact that the galvanized coating helps protects the steel from corrosion.
Where is Galvanized Grating used?
HDG Galvanized steel grating with heavy zinc coating protection serves widely in construction of strong, quick and durable bearing structures and frames in offshore oil rig platforms, refineries, walkways, flooring treads and many other industries.
Heavy welded steel bar grating galvanised is popularly used as Offshore Platform Grating Panels. Steel gratings serrated panels covered with bent diamond pattern checker plate angle nosing offer a safer and popular platform grating solutions.

The advantages, specific application and features of steel grating:
Steel grating offers the following advantages compared with steel grid sheets:
Steel structural platform has 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.
Steel grating with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway, can be used for ceiling, interior decoration, decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.
Steel grating products are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering, and they offer the following the features:
Aesthetic outlook: Simple lines and silver appearance meeting the modern trend.
The best drainage: Leakage area of 83.3 percent, more than twice of cast iron products.
Hot-dip galvanized treatment: Good rust-proof property, maintenance-free replacement.
Anti-theft design: The cover and the frame is joint with hinge offering security, safety and open convenience.
