Entrega rápidaExpanded metal gratings are an excellent choice for elevated walkways in lieu of using traditional bar grating. Available in carbon steel, expanded metal gratings are lighter in weight compared to standard bar gratings. This 6/25lb expanded metal grating has a opening dimension of 1.412″ x 5.33″ and a strand thickness of .312″. Available in 4′ x 8′ sheets, these can be supplied in mill finish, painted black, or hot dipped galvanized.
Expanded metal grating refers to the treads used for various platforms and office personnel transportation. Compared with ordinary metal mesh, expanded metal grating must have a satisfactory anti-slip effect and a certain bearing capacity to ensure the life of service personnel on the post.
The expanded metal grating deems appropriate, and adopts the heavy metal mesh products in the expansion mesh series. Various product attributes: non-slip appearance, wear-resistant, can bear more than 800 kg per square meter, high tensile strength, strong toughness, no rust. Anti-aging, strong flame retardancy, smooth mesh surface and other properties.
Accurate Alloys expanded metals gratings are manufactured in carbon steel, aluminum and stainless steel.Expanded metal grating size chart

LOAD CRITERIA:
1. Concentrated load is applied at mid-span and is in units of pounds per foot of grating width.
2. Deflection is at the mid-span, and is measured in inches.
3. The test specimens on which this table is measured were welded at alternate strands to an angle fixture.
4. Testing has shown that if the both ends are not welded in place the capacity of the grating is drastically reduced.
A A variation in weight per square ft. of ±5 % is permissible, based on the weight of any sheet or bundle.
B A tolerance of ±5% is permitted in dimensions, center to center..
Application Of Expanded metal grating:
6.25#expanded metal grating is widely used in outer wall multi-storey building scaffolding pedals, high-altitude platform pedals, facility platforms, tower crane platforms, factory office platforms, ship production platforms, power plant walkway platforms, chemical plant walkway platforms, etc.
Heavy-duty steel grating
Heavy-duty steel grating is a high-load-bearing metal grating designed for the most demanding industrial and infrastructure applications. It is manufactured using thicker and wider load-bearing flat steel bars, with a thickness of 6mm or more and a width of 50mm or more, welded or pressure-locked with cross bars to form a rigid, one-piece structure. Heavy-duty steel grating is capable of supporting loads exceeding 10 tons, making it ideal for heavy traffic areas, large-span platforms, and critical structural flooring.
FRP Grating
FRP grating, also known as fiberglass reinforced plastic grating, is a high-strength, corrosion-resistant composite grating manufactured from glass fiber rovings and thermosetting resin. Unlike steel grating, FRP grating does not rust, does not conduct electricity, and is not affected by most chemicals, making it the preferred choice for chemically aggressive, humid, and electrically sensitive environments. It is widely used for walkways, platforms, stair treads, trench covers, and structural flooring in chemical plants, water treatment facilities, marine environments, and food processing plants.
Trench cover
Trench cover grating is a heavy-duty metal grating specifically designed to cover drainage trenches, cable channels, and service ducts while supporting pedestrian and vehicular traffic. Each cover is manufactured by welding load-bearing flat steel bars and twisted cross bars together to form a rigid, open, and slip-resistant surface. The open pattern allows water, oil, and debris to drain freely into the trench below, preventing surface flooding and keeping walkways and traffic areas clean and safe.
Stainless Steel Grating
Serrated steel grating is a high-strength, slip-resistant metal grating manufactured with serrated edges on the load-bearing flat steel bars. The serrated profile creates additional grip points on the top surface of each bar, delivering superior traction in wet, oily, icy, or contaminated conditions. This makes serrated steel grating the preferred choice for industrial platforms, walkways, stair treads, drainage covers, and structural flooring where standard smooth grating may not provide sufficient slip resistance.
