China Manufacturer Factory Supply Galvanized Steel Grating for
Industrial Flooring, Walkway, Catwalk, Driveway
Bar grating is made up of parallel bars that are connected together
with perpendicular bars. The bars are most commonly connected
through welding, however, there are other ways of joining the bars
together. Alternatives include riveting, close meshing,
press-locking and more. The most economical method of joining is
determined by the materials being used and the thickness of the
bars.
Bar grating can be made out of a variety of different materials but
is most commonly made from steel or aluminum. It has a very high
ratio of strength-to-weight and a lot of open space, making it a
widely used option for industrial flooring. However, it is also
used for things such as fire escapes, street drains, and bridges.

Galvanized grating, also called galvanized steel grating or
galvanized steel bar grating, refers to the steel bar grating made
of steel bar with hot dipped galvanized surface.
The carbon steel provides an economical, high strength for uses in
most industrial and commercial applications. And hot dipped
galvanized surface treatment supplies excellent corrosion
resistance performance for durability.
Steel grating is available in various material, such as stainless
steel, aluminum, and galvanized steel. Among them, the galvanized
steel grating is the most cost effective and economical type with
long service life and high load bearing stength. And it is the most
widely used in industrial, commercial and residential projects.
