Steel grate, also known as steel grating or grid plate, is a steel product made of flat steel and cross bars arranged crosswise and welded at a certain interval, with a square grid in the middle of the structure.
Ⅰ. Basic characteristics of steel grate
Material: It is usually made of carbon steel or stainless steel. Carbon steel is widely used due to its high strength and low cost, while stainless steel is suitable for more demanding environments due to its excellent corrosion resistance.
Surface treatment： Common treatment methods include hot-dip galvanizing, cold-dip galvanizing, electro-galvanizing, spray painting, immersing in anti-rust oil, immersing in plastic, etc. Among them, hot-dip galvanizing can significantly improve the corrosion resistance of steel gratings.
performance: Steel grating plate has the characteristics of high strength, lightweight, strong anti-corrosion ability, durability, beautiful appearance, bright surface, etc. At the same time, it also has the properties of ventilation, lighting, heat dissipation, anti-slip, explosion-proof, etc.
Ⅱ. What are the classifications and specifications of steel gratings?
- Classification:
According to the welding method, it can be divided into pressure welding type, interlocking type, locking type, and through welding type.
According to the shape of the side surface of the load-bearing flat steel, it can be divided into flat type, tooth type, and “I” type, etc.
According to the purpose, it can be divided into general-purpose steel grating plates and special-purpose steel grating plates, such as trench covers, step plates, etc.
According to the material, it can be divided into stainless steel grating plates and carbon steel grating plates.
- Specifications:
The vertical strip spacing is usually 30, 40, 60 mm, and there are non-standard spacings such as 25, 34, 35, 50, etc.
The horizontal bar spacing is usually 50, and 100mm, and there are non-standard spacings such as 38, 76, etc.
The width range is generally 20–60mm, and the thickness range is generally 3–50mm.
Ⅲ. How are steel gratings made?
- Shearing and punching: According to the design requirements, the raw materials are sheared into the required size and punched by a punching machine.
- Welding: The sheared steel bars are welded into a grid shape using resistance welding or arc welding. The welding quality directly affects the overall strength and stability of the steel grating.
- Hot-dip galvanizing: A layer of zinc is plated on the surface of the steel grating to form a protective layer to improve its corrosion resistance.
Ⅳ. Where are steel gratings used?
Steel grating is widely used in many fields due to its excellent bearing capacity, corrosion resistance, water permeability and anti-slip properties:
- Industrial platforms and walkways: used as floor materials for platforms and walkways in factories, mines, docks and other places.
- Petrochemical and chemical equipment:used to make parts such as partitions, filters, container covers, etc.
- Equipment maintenance and work platforms:used as the main materials for equipment maintenance, platforms, operating tables and other facilities at industrial production sites.
- Stairs, platforms, stairs, overpasses:widely used in public places such as industrial plants, commercial buildings, gymnasiums, etc.
- Steel structure buildings: used as floor materials, fences and handrails in large steel structure projects such as high-rise buildings and bridges.
- Sewage treatment and landfill: used as key components of environmental protection facilities such as covers and walkways.
- Transportation field: used as safety facilities such as vehicle guardrails and guardrails.
- Warehouses and logistics: used as the main materials for equipment such as stacking racks, shelves, and truck sheds.
- Public facilities: widely used in facilities such as garbage bins, public toilets, and bus stops.
