SELECTION GUIDE
Steel grating is widely used in industrial applications, including factory platforms, sidewalks, stair treads, trench covers, fences, ceilings, etc. Can ensure personnel safety and provide high strength, high load-bearing capacity, and excellent corrosion resistance. We have stainless steel grating, galvanized welded steel grating, locking steel grating, and heavy-duty steel grating for you to choose from. So how do you choose the right steel grating? Here are some tips on how to choose the right steel grating for your reference:
Correct steel grating material, type, mesh size, and surface treatment method
1. Welded Steel Grating and Pressure Locked Steel Grating
The difference between the two types of steel grilles lies in their production methods
Welded Grille
Welded steel grating is formed by resistance pressure welding at the intersection of bearing bar and cross bar. The horizontal bar is generally made of round steel or twisted square steel, and the surface can be covered with patterned plate welding. The structure is strong and strong, and is commonly used in sidewalks, stair treads, fences, and floors.
Locking Steel Grating
Compression lock steel grating is a steel grating product that tightly locks bearing bars together through high-pressure mechanical equipment. Compression grating has higher strength and load-bearing capacity compared to ordinary grating.
2. Material Selection
When choosing materials, we need to consider the expected use of the grille and environmental factors. Should we use it for ordinary grille walkway panels or for heavy load situations such as trench covers that need to pass through vehicles, or for environments with high levels of corrosion. In these cases, it is necessary to ensure that the grille has sufficient strength and corrosion resistance to ensure its long-term use. Each material has its unique characteristics and uses. Here we would like to briefly introduce it to help you choose the appropriate materials.
| Material | Feature | Application |
| Galvanized Steel | Economical, high strength, excellent corrosion resistance | Suitable for steel structure platforms and maintenance platform walkways in petrochemical industry, power plants, municipal engineering , etc. |
| Mild Steel | Economical, good ductility, excellent welding and stamping properties. | Suitable for municipal construction, interior decoration, building materials, platform aisles, etc. |
| 304 Stainless Steel | Excellent corrosion resistance, heat resistance, high tensile strength | It is suitable for chemical plants, food plants, power plants, wastewater treatment and other places where high temperature operations are required. |
| 316 Stainless Steel | Compared with 304 stainless steel, it has better corrosion resistance and pitting resistance, and higher heat resistance | Used in chemical, pulp and paper processing, textile equipment, petroleum refining, etc. |
| Aluminum Alloy | Light weight, good corrosion resistance, beautiful appearance | Widely used in indoor ceilings, outdoor curtain walls, other decorative applications and mechanical equipment maintenance platforms. |
3. The Influence of Grid Size
The commonly used mesh sizes for welding steel grating include 33mmX33mm, 33mmX50mm, 33mmX100mm, and 34mmX38mm. Depending on the usage environment and load requirements, the mesh size may vary. We can customize different mesh sizes according to your needs. The following are several requirements for determining the size o
1. Load bearing: The smaller the mesh size, the higher the load-bearing capacity of the steel grating, but an overly dense hole spacing can lead to a decrease in light transmittance. We need to consider comprehensively to customize the required hole spacing.
2. Purpose: The larger the mesh size, the higher the light transmittance. A larger hole spacing may cause some objects to fall through the grille, which may lead to safety issues.
3. Customer requirements: You can provide the requirements for your usage environment, and our professional design team will provide suggestions to ensure that your usage requirements are met.
01
Smaller grids not only have better load-bearing capacity, but also prevent objects from falling off
01
The larger the grid, the better the ventilation and transparency.
4. Surface Treatment
01
The untreated steel grating made of low-carbon steel material is black in color, while the stainless steel grating can be polished to make the surface more beautiful.
02
The surface treatment of low-carbon steel grating generally adopts galvanizing treatment, which makes the surface clean, beautiful, and has good corrosion resistance.
03
The surface treatment of steel grating can also provide additional customized services according to your special needs, such as painting treatment, powder coating spraying treatment, etc. This will make the surface color of the steel grating more diverse.
04
The bearing capacity of steel grating. Different heights and thicknesses of bearing bars, sizes of bearing bar grids, and types of crossbars will result in different bearing capacities. If you do not have specified specifications, our team can customize the most cost-effective specifications based on your design drawings to meet your needs.
Slip Resistance
There are two surface forms of steel grating: one is flat and the other is serrated. serrated grating is usually used in rings with high anti slip requirements, such as humid environments and places with frequent rain and snow weather to increase anti slip performance.
