Metal bar grating is made by welding with flat steel and bars with certain distances. It goes through the cutting, opening, edging, and other processes. The metal gratings enjoy the feature of high strength, light structure, good ventilation, perfect lighting performance, high load capacity, resistance to deformation, convenience for loading, and other features. The hot-dip galvanized coating gives the metal grating excellent anti-corrosion.

Features and Advantages
* Different Materials for Choice
Metal bar grating can be made of different materials including carbon steel, aluminum steel, and stainless steel. Carbon steel grating is the most economical type with galvanized and painted surface treatment. The aluminum steel grating features lightweight and outstanding corrosion resistance while the stainless steel grating has outstanding chemical stability to be used in harshest environments.
* Various Fabrication Methods
Metal bar grating can be classified into different types according to the fabrication. The cross bars are jointed to the bearing bars through welded, press-locked, swage-locked, and riveted connections. The main types are including welded bar grating, press-locked grating, swage-locked grating, and riveted grating.
* High Load Capacity
The solid and firm structure makes the product have a high load-carrying capacity. Especially the swage-locked grating and press-locked grating, which can supply excellent lateral stiffness to the steel grating. The product can not only available for pedestrians walking but also permits heavy vehicles safely passing through.
* Humanization Design
Metal grating is available for vehicle equipment, such as wheelchairs, roller skates, and other vehicles. And there is a type of steel grating that has a serrated surface and excellent slip-resistance performance. The product is widely used in places filled with water, oil, and other elements to prevent slip accidents. It can secure the safe access of pedestrians and vehicles. Additionally, it can prevent the workers working on the platform from slipping down.
Applications
Metal grating panels are popular with industrial and commercial areas and is widely used as stair treads, walkway, drainage trench cover, sun shade panel, observation tower, bridge deck, and various platforms for temporary or permanent applications in daily life.
Packaging Methods
* Strap Packaging: generally applicable to relatively neat steel grating.
* Pallet Packaging: generally for export packing.
* Screw Rod Fixation: Four screw rods through aperture for screw-locked packaging.
