Hot-Dip Galvanized Steel Grating

The original plate is made by welding load flat steel and crossbars in a certain spacing, then it is deeply processed into the finished product as required by the customer through cutting, notching, punching, and edge wrapping, etc., on a high-voltage resistance welding machine.

Galvanized steel grating is categorized into the following types:

1. Hot-dip galvanized steel grating, categorized by manufacturing process, includes pressure-welded hot-dip galvanized steel grating and pressure-locked hot-dip galvanized steel grating.

2. Hot-dip galvanized steel grating surfaces are categorized by shape into toothed hot-dip galvanized steel grating and flat hot-dip galvanized steel grating.

3. Type I hot-dipped galvanized steel grating and composite hot-dipped galvanized steel grating.

Labeling Method:

(1) Hot-dip galvanized steel grating扁steel spacing: Differentiated by series: Series 1 is 30mm; Series 2 is 40mm; Series 3 is 60mm.

(2) Hot-Dipped Galvanized Steel Grating Bar Spacing: Series 1 is 100mm, Series 2 is 50mm. Other specifications available upon request.

(3) Hot-Dip Galvanized Steel Grating: Made of Q235 or stainless steel, available in flat, anti-slip toothed, and I-section designs. Common sizes include 20*5, 25*5, 25*3, 32*5, 32*5, 40*5, 40*3, 50*5, 65*5, 75*6, 100*8, and 100*10.

(4) Hot-Dip Galvanized Steel Grating Crossbars: Made of round steel, twisted square steel, square steel, or hexagonal steel with material grade Q23 or 304 stainless steel. Twisted square steel is produced by drawing through square dies from round steel wire and twisting it, with common sizes including 5*5, 6*6, 8*8mm, etc.

Features include: high strength, lightweight structure: the sturdy grid weld structure offers high load-bearing capacity, light structure, and ease of hoisting; attractive appearance, durable in use.

Hot-Dip Galvanized Steel Grating Applications: Widely used in platforms, walkways, bridges, manhole covers, ladder, fences, railings, etc., for industries such as petrochemical, power plants, water treatment plants, sewage treatment plants, municipal engineering, and environmental protection projects.

Composite steel grating

This product is composed of steel grating with certain transverse load-bearing capacity and patterned boards with a sealed surface. After the composite steel grating is hot-dip galvanized, it may exhibit warping and deformation due to heat, especially with larger sizes, making leveling challenging. Please pay attention to the selection of sizes. The composite steel grating commonly uses series 3 steel grating as the base, but series 1 or series 2 steel gratings can also be used. Patterned steel gratings typically use 3mm thick plates, but 4mm, 5mm, or 6mm plates can also be employed. A reinforced mesh can be attached to the front or back of the composite steel grating to prevent small items from falling out, and using such reinforced mesh in grain silos, dining halls, and warehouses can prevent rodents and other small animals from entering.

Composite Steel Grating Installation Method: Directly weld the steel grating or tread plate to the supporting steel structure, and apply two coats of zinc-rich paint at the welding joints. Use steel grating installation clamps for assembly without damaging the galvanized layer, and disassembly is convenient. Each set of installation clamps includes one top clamp, one bottom clamp, one M8 round head bolt, and one nut. Stainless steel installation clamps or bolt-connection fastening methods can be provided upon request. The typical installation gap for steel grating is usually 100mm. Ensure the installation is secure and reliable during assembly, and regularly inspect to prevent clamp loosening or detachment. For steel grating near vibration, it is recommended to weld or add rubber pads.
