What is a Grating Panel? Everything You Need to Know About Grating Panels

Grating panels, also known as grating floor panels, consist of parallel load-bearing bars that can be either flat or serrated, with equal spacing between them. These bars are held upright by twisted square crossbars, forming a strong mesh structure. Today, grating panels are widely used in construction projects, factories, and even in everyday life. Let’s explore this versatile material with Butraco through the article below!

1. What is a Grating Panel?

A grating panel is a multi-functional material made from steel, aluminum, stainless steel, and other materials, and is often referred to as a grating cover. The metal bars in a grating panel are arranged in parallel with equal spacing and are held in place by twisted square crossbars, forming a steel mesh panel.

The load-bearing grating panels are produced using non-corrosive bars. Grating panels are typically composed of:

Flat Bars: These bars have low carbon content (e.g., SS400, A36 steel, Q345B, Q235, or C45). They usually range in thickness from 2mm to 12mm and in height from 20mm to 150mm.
Twisted Square Bars: These bars connect the flat bars together. They are typically 6×6 mm in size and are designed with a twisted pattern.

Common Grating Panel Designs:

• Manhole covers and grating floor panels
• Grating platforms: These are mesh floors with a design similar to that of grating panels, often used as scaffolding platforms or elevated walkways in industrial parks, construction sites, shipbuilding, and the oil & gas industry.
• Hot-dip galvanized grating panels
• FRP composite grating panels

Specifications and Dimensions of Grating Panels:

• Distance between load-bearing bars: 30mm, 40mm, or 60mm
• Distance between twisted square bars: 40mm, 50mm, 60mm, or 100mm

2. Applications of Grating Panels

Grating panels offer high corrosion resistance and open surfaces of up to 80%, making them ideal for a wide range of applications. They are commonly used in power plants, oil and gas industries, chemical and machinery industries, parking lots, shipbuilding and seaports, etc. Additionally, grating panels are widely applied in floors, walkways, platforms, and covers.

Specific Applications of Grating Panels:

• Grating Platforms: Grating platforms are assembled from multiple grating panels. They are installed at elevated positions to facilitate tasks such as assembly, operation, maintenance, and machinery repairs.
• Grating Drain Covers: Grating panels, when assembled, form drain covers that function as debris filters, preventing waste from clogging the drainage system and ensuring quick water flow.
• Grating Stair Treads: Grating floor panels are also used to create stair treads for residential and public structures.
• Load-Bearing Grating Floors: Similar to working platforms, these grating floors feature greater thickness. Crossbars are welded together with flat bars to support heavier loads and are commonly used in transportation infrastructure projects.

3. Grating Panel Production Process

The production of grating panels follows four main stages:

3.1. Stage 1: Preparing Load-Bearing Flat Bars

Grating panels are constructed from flat steel bars and crossbars. Therefore, the first stage of production involves preparing the load-bearing flat bars according to the grating panel blueprint.

3.2. Stage 2: Preparing Crossbars

After preparing the flat bars, the next step is to prepare the crossbars. This preparation involves three steps:

• Step 1: The steel crossbars are fed into a machine to twist them. This process enhances the strength and load-bearing capacity of the product.
• Step 2: Once twisted, the crossbars are fed into a flattening machine to eliminate any curves or warps.
• Step 3: The crossbars are thoroughly inspected to detect and remove minor defects, ensuring a perfect final product.

3.3. Stage 3: Welding the Grating Panel

Once the main components are ready, the production team proceeds to weld the grating panel. This process includes:

• Welding the frame to establish the product’s size and structure.
• Welding the flat load-bearing bars onto the frame.
• Welding the twisted crossbars perpendicular to the flat bars to create a strong mesh structure.

3.4. Stage 4: Surface Protection and Final Inspection

After welding, the grating panel is coated with an appropriate protective layer based on the material. Once coated, the product undergoes final inspection to identify any defects, which are corrected immediately to ensure the product meets quality standards.

4. What Are the Advantages of Grating Panels Manufactured by Butraco?

The grating panels produced by Butraco offer the following advantages:
