Steel Bar Grating

Raw Material of steel bar grating

Steel bar grating is made by welding bearing bars and cross bars together. Bearing bar is typically ordinary steel plates available in various models and sizes. Commonly used steel types include 253, 255, 303, 304, 305, 403, 404, 405, 505, and so on. In the model number, 253 represents that the flat steel has a width of 25mm and a thickness of 3mm, with subsequent models following a similar pattern. AGICO provides customization service so that our customers can choose the raw material they need.

How does AGICO Manufacture Steel Bar Grating?

The production of steel bar grating typically involves the following steps, starting from the selection of raw materials:

Step 1: Raw Material Selection

The raw materials used for manufacturing steel bar grating are typically high-strength, low-carbon steel. It is important to choose the appropriate thickness to ensure that the final product has good geometric shape and relatively low maintenance costs.

Step 2: Assembly Welding

Steel bar grating is composed of two or more metal stripes that are fixed together through welding methods. Combination welding, such as electron beam welding or gas shielded welding, is commonly used to ensure the strength and durability of the welded joints.

Step 3: Molding

Molds are essential components in the production of steel grating. Molds are usually manufactured according to the desired specifications and design details to ensure accurate dimensions of the grating and produce stable, uniform, and deformation-resistant steel grating.

Step 4: Cutting

Cutting is a crucial step in the production of steel grating. Highly automated cutting equipment, such as mechanical cutting, flame cutting, or plasma cutting, is used to cut the steel bar grating material into the predetermined sizes of the panels.

Step 5: Cold Pressing

Cold pressing is employed to create the unique serrations and round bars in the final product. By adjusting and controlling the pressure, a stable and durable texture and shape are formed, resulting in excellent anti-slip properties and load-bearing strength.

Step 6: Surface Treatment

Surface treatment of steel bar grating is typically carried out to enhance the surface hardness, corrosion resistance, and appearance quality of the material. Common methods include hot-dip galvanizing, painting, or electrophoretic coating.

Step 7: Quality Inspection

Strict quality control procedures must be followed throughout the production process, from raw material selection to the final product leaving the factory. This ensures that the end product meets the required standards and specifications, guaranteeing product quality and safety.

How to Choose Steel Bar Grating?

Type Selection: First, it is necessary to understand the load-bearing capacity of the steel grating and the span of the installation. Then, based on the “Load-Span and Deflection Relationship Table,” the best type of steel grating should be selected in coordination with the manufacturer.

Workmanship: Choose steel grating with a flat surface and small welding gaps. This ensures precise and sturdy workmanship of the steel grating.

Application Area: Consumers should purchase steel grating based on the requirements of their specific environment. Factors such as moisture, corrosion, and temperature greatly impact the service life of the steel grating. Therefore, before making a purchase, it is important to inquire about the application area and corrosion resistance of the steel grating, as these factors significantly affect the overall quality of the product.

Specific Applications: Determine whether the steel grating will be used for stair treads, trench covers, platforms, or other purposes. It should be noted that both trench covers and platform steel grating have load-bearing requirements, and the orientation of the flat steel is crucial. With the same dimensions but different orientations of the flat steel, the weight-bearing capacity can vary significantly.

Deflection and Deviation: The deflection of the steel grating should not exceed 1/200 of its span and must not exceed 6mm at maximum.

Layout Rules: When selecting steel grating, the nominal width table should be given priority, and if the original width is not available, the nominal width value corresponding to the number of flat steel should be chosen.
