AS1657 - 1992 Standard Bearing Bar Pitch 30mm Plain Welded Steel
Grating Welded Steel Grating Introduction: Steel Grating SpecificationSteel grating is commonly made of flat steel panel and supporting
bars welded together with setting spacings. It goes through
cutting, opening, edging and other processes. The popular vertical
bar grating spacing is 30mm, 40mm or 60mm, horizontal bar grating
is 50mm or 100mm normally. Details information please refer to the
specification List below. Surface Treatment: hot-dipped galvanized or electro galvanized mild
steel. Stainless Steel GratingStainless steel bar grating is a choice for corrosive environments
such as chemical, food and hydro processing areas. It is available
in welded and press locked as well as in many bearing bar sizes. Materials: The most common material is Type 304 (SUS304), however,
Type 316 (SUS316) or Type 316L (SUS316L) is also available. 304
stainless steel is the most popular type contains both chromium and
nickel to provide excellent balance resistance and workability. 316
stainless steel is better corrosion, pitting resistance and higher
strength at elevated temperatures than 304. 316L is extra low
carbon variation of 316 to avoid carbide precipitation due to
welding. Aluminum Gratingaluminum grating is designed to be a high-strength, low-weight
product that uses an I-bar or rectangular bearing bar with cross
rods hydraulically swaged under high pressure. Thus, giving you a
rigid, virtually maintenance-free flooring product. Similar to steel grating, aluminum grating can be pressure locked
as an alternative to swage locked. This application process also
allows the customer to choose a close mesh grate where certain
special needs are to be met. Open Mesh GratingThe open mesh steel grating is a flat panel with a light structure
firmly welded together. It is widely used for industrial ladders,
decking safety, ventilation ceilings and floors, platform and stair
tread protection panels. The open spacing design instead of solid
metals allows good ventilation, and easy flow of lighting and heat.
The standard sheet size is 1m x 6m standard type (special size and
American standard size are also customizable). Mostly Used Specifications of Steel Mesh Gratings from our
