Hot-Dip Galvanized Steel Grating

Hot-Dip Galvanized Steel Grating

Hot-dip galvanized steel grating is a widely used product in steel grating applications, offering not only an aesthetically pleasing appearance but also excellent corrosion and rust resistance, thus extending its service life and gaining the trust of numerous customers.

Hot-dip galvanized steel grating panels feature high strength and light structure; their sturdy grid pressure-welded construction offers high load-bearing capacity, light structure, and ease of hoisting; they are also aesthetically pleasing and durable.

Corrosion Resistance: A stable protective film forms on the zinc layer surface within the pH range of 6 to 12.5, offering excellent corrosion resistance.

Hot-dip galvanized steel grating applications: Widely used in platforms, walkways, gangways, manhole covers, ladder covers, fences, railings, etc., for platforms, walkways, gangways, manhole covers, ladder covers, fences, railings in fields such as petrochemicals, power plants, waterworks, sewage treatment plants, municipal engineering, and environmental protection engineering.

Heavy-duty steel grating

1. Heavy-duty steel grid introduction:

Heavy-duty steel grating refers to the type with bearing steel width over 65mm and thickness over 6mm. Its transverse bars are typically made of flat steel or steel rebar with diameters of 10mm or 12mm.

2. Heavy-duty steel grating applications:

Heavy-duty steel grating is designed and manufactured for applications requiring heavy loads, suitable for airports, highways, industrial platforms, port terminals, and other special demand scenarios.

3. Heavy-duty steel grating classifications:

4. Heavy-duty steel grating can be divided into two types according to the production process: heavy-duty welded steel grating and heavy-duty riveted steel grating.

A. Heavy-duty welded steel grating refers to a type of grating where the crossbars are made of rebar, suitable for single-direction loading applications.

B. Heavy-duty pressed steel grating refers to steel grating with flat steel bars, suitable for bidirectional loading applications. However, it is significantly more expensive than welded steel grating, and is generally not recommended for use.

C. Surface shapes can be categorized into flat heavy-duty steel grating and toothed heavy-duty steel grating.

Due to cost considerations, we recommend using flat steel grating in general situations, and heavy-duty toothed steel grating for anti-slip applications such as offshore drilling platforms.

Composite steel grating

This product is composed of steel grating with certain transverse bearing capacity and patterned boards with a sealed surface. After hot-dip galvanizing, composite steel grating may experience warping and deformation due to heat, especially with larger sizes, which can be difficult to flatten. Please note the selection of size. The composite steel grating commonly uses Series 3 steel grating as the base, but Series 1 or Series 2 can also be used; patterned steel grating typically uses 3mm thick plates, but 4mm, 5mm, and 6mm plates can also be chosen. A double mesh can be formed by welding steel mesh to the front or back of the composite steel grating, preventing small items from falling out. The use of double mesh in grain silos, restaurants, and warehouses can prevent small animals like rats 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, which do not damage the galvanized layer and are easy to disassemble. 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 methods can be provided upon request. The typical installation gap for steel gratings is 100mm. Ensure that the installation is firm and reliable during assembly, and check it regularly to prevent clamps from loosening or falling off. It is recommended to weld or add rubber pads to the steel grating near vibrations.

Platform steel grating

Platform steel grating is a versatile product in the wide range of steel grating panels, primarily used in various platforms across factories, workshops, mining, and ports. It offers an aesthetically pleasing and easy-to-install option, representing a new generation of building products.

Platform specialty steel grating products include:

1. Kick plates (edging plates), patterned steel plate guards, and mounting accessories can be additionally welded around the steel grating perimeter.

2. Utilize flanges of different specifications than those on the steel grating, or use angle iron, channel steel, square tubes, etc., for edging.

3. Handles and hinges can be installed on the platform steel grating panels for frequent movement or opening.

4. Generally speaking: The welding standard for the edge of platform steel grating panels is as follows: Series 1 - weld every five panels; Series 2 - weld every four panels; Series 3 - weld every three panels. The welds are single-sided angle welds not less than 3mm, with a length of 20mm.
