Hot Dipped Galvanized Metal Grating 505 Serrated Bar Safety Walkway Steel Grating
Galvanized Steel Grating Description
The press-lock steel grid is constructed with two close-tolerance slotted bars bonded together
by tremendous hydraulic pressure. And this production can let press-locked grating be a permanent
locking. With high strength and firm structure, it's widely used in industrial factories or parks,
commercial buildings, municipal engineering as stair treads, platforms, walkways, security screens,
tree covers, trench covers, drainage covers and so on.
Only the bearing bars are notched, the cross bars are common plain steel. And they have
different height.
Welded metal grating is joined at the intersection of the bearing bars and cross bars. Welded bar grating is a versatile option for light to moderate loads. When heavy duty loads are present, the Heavy Duty metal grating provides a nice option. This is appropriate for highways, airport runways, bridge floors and all wheel traffic applications.
Light Duty bar grating ranges in size from 3/4" x 3/16" to 2-1/2" x 3/16". Heavy Duty bar grating ranges in size from 1-1/4" x 1/4" to 6" x 1/2"

Steel Grating Type
Versatile and high quality
Steel grating has been widely used in all walks of life all over the world. Steel grating is mainly used as platform plate, ditch cover, stair tread and building ceiling.
Steel grating is made by welding with flat steel and bars with certain distances. It goes through cutting, opening, edging and
other processes. The products enjoy the features of high strength, light structure, high bearing, convenience for loading and
other properties. The hot dipped zinc coating gives the product excellent anti-corrosion resistance.
Features
1.Resistant to extremely high temperature;
2.Corrosion resistance and alkaline resistance.
3.Anti-rust.
4.Skid resistance.
5.Very rigid surface can stand heavy wear and tear.
Quality Control
Steel grating application
Application: electro forged step Steel griting are widely used by various plants such as electric power,petroleum,chemical industry,machinery industry,shipbuilding,harbor,oceanographic engineering,building,paper mills,cement plant,medicine,spinning and weaving,foodstuff factory,transportation,municipal administration,parking lot,etc.
It also used in bridges for vehicles and pedestrians.
Packing & Delivery
(1) Bandage and Paperboard: Generally applies to neat steel plate;
(2) Screw Locking Method: Use 4 screw rods through the aperture of the steel grid, for high strength;
(3) Steel Pallet: Traditional export packing.
