Hot dip galvanized steel grating is the best choice for steel platforms in airports. Grating with 30 × 3 mm thick load bearing bars with a pitch of 30 mm and traverse bars at 50 mm or 100 mm is the suitable one. Steel grating, with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway.

Dec 10, 2017 · ASTM A767 Standard Specification for Zinc-Coated (Galvanized) Steel Bars for Concrete Reinforcement, covers zinc coatings applied by the hot-dip process on individual steel reinforcing bars before fabrication used in concrete. HOT DIP GALVANIZED - AK SteelHOT DIP GALVANIZED STEEL, known as ZINCGRIP® Steel, is continuously coated on both sides with a zinc coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc.
The hot dip Galvanizing process The galvanizing process consists of three basic steps:surface preparation, galvanizing and in-spection. SURFACE PREPARATION Surface preparation is the most important step in the application of any coating. Any failures or inadequacies in surface preparation will immediately be apparent when the steel is withdrawn Hot Dip Galvanized Steel Sheet & Coil - GI coils - Dana SteelHot Dip Galvanized Steel Coil is produced by passing Cold Rolled Steel Coil through a Molten bath of Zinc at temperatures of around 460 degrees Celsius.The Zinc coating on the steel coil substrate acts as a barrier between the atmosphere and the surface of the metal.
Oct 15, 2019 · Quality of zinc layer is assessed readily by eye, and the thickness is easy to test with magnetic thickness gauges according to the ISO1461 and the requirement of clients. You can check the detailed standard of hot-dipped galvanized steel below. Hot-dip galvanizing process. Here is a diagram describing the process. You also can see the video below. ISO - ISO 1461:2009 - Hot dip galvanized coatings on sheet, wire and woven or welded mesh products that are continuously hot dip galvanized; tube and pipe that are hot dip galvanized in automatic plants; hot dip galvanized products (e.g. fasteners) for which specific standards exist and which might include additional requirements or requirements which are different from those of ISO 1461:2009.
