What are the size specifications for steel grating to choose from?
The size and specification selection of steel grating should be determined comprehensively based on parameters such as flat steel, cross bars, grid spacing and overall dimensions. The following is a specific classification description:
I. Dimensions of Flat Steel
Thickness : Common types include 3mm, 4mm, 5mm, 6mm, etc. The greater the thickness, the stronger the load-bearing capacity .
Width : usually 20mm to 100mm, such as 30mm, 40mm, 50mm, etc. An increase in width can enhance the load-bearing performance .
Ii. Crossbar Parameters
Diameter : Commonly used are 6mm, 8mm, and 10mm. The larger the diameter, the better the fixation effect .
Spacing : The standard is 50mm or 100mm, and non-standard options include 38mm, 76mm, etc. The smaller the spacing, the higher the stability .
Iii. Grid Specifications
Spacing :
Vertical bar spacing: 30mm, 40mm, 60mm are standard for .
Mesh size: common 30×100mm, 40×100mm, 50×100mm. The smaller the mesh, the stronger the load-bearing capacity .
Shape : mostly square or rectangular, special shapes can be customized for specific requirements.
Iv. Overall Dimensions
Length : standard 1m, 2m, 3m, customizable up to 6m.
Width : commonly 1m, 1.2m, 1.5m, and supports adjustment of as needed.
V. Load-bearing Grade
Light type (1-3 tons /㎡) : suitable for sidewalks, stairs .
Medium-sized (3-5 tons /㎡) : used for industrial platforms, parking lots .
Heavy-duty (5-10 tons /㎡+) : docks, heavy industrial environments .
Vi. Surface Treatment
Galvanized coating : 45-80μm, thickness affects corrosion resistance .
Spray paint : 60-100μm, balancing aesthetics and protection .
Purchase suggestion : Select parameters based on the actual scenario. For example, for ordinary construction sites, Q235 carbon steel (economical and practical) can be chosen. For special environments, non-standard sizes or reinforced materials need to be customized .
