heavy duty steel grate

1.Galvanized steel grating 2.Metal grating 3.ASTM A123,SS400 4.Common pitch:30mm&40mm 5.Used in flooring,walkway           Metal grating consists of parallel bearing bars with crossbars -- or crimp bars -- set perpendicular to the bearing bars to hold them in place. The grating may be fabricated from carbon steel alloys, aluminum or stainless steel, depending on the needs of the project. Stainless steel can withstand high temperatures and is corrosion-resistant. Many configurations are available, including variations in the bar spacing, surface quality and load-bearing strength

  Heavy duty grating are manufactured usually where vehicular traffic is required. Bearing bars are wider and deeper than on standard gratings and the mesh sizes tend to be smaller in order to achieve the panel strength required. Panels are manufactured in a wide range sizes.

  Louvre gratingare normal pressed gratings but with the horizontal bars set at 45 degrees. These can be manufactured in a wide range of panel sizes and in a wide range of mesh settings depending on the levels of free-air flow and sight characteristics required.

  perforated grating have peforated holes at selected centres depending on the application and combines strength, durability and a comparatively lightweight. Usually used as walkway, platform or stair treads. This type of grating can also come complete with smaller water holes in between the perforations to provide a self-draining capacity

Notes for ordering:

1. Please clearly state specifications, types, quantity and required surface treatment. 

2. Please provide complete design-related layout plan, structural drawing, sectional view and joint drawing. 

3. In the case of stair treads, please specify its type, length, width, quantity and surface treatment.
