Hot Dip Galvanized Steel Grating
In modern industrial and scientific research fields, the demand for precise measurement and efficient optical equipment is growing. As an important optical component, gratings are widely used in spectral analysis, laser ranging, imaging systems, and other fields. Large gratings with a size of 5800×1000mm not only represent advanced manufacturing technology but also ensure precise measurement and efficient experimentation.
The ultra-large grating with dimensions of 5800×1000mm can meet the application needs of large areas and high resolution. It can provide a wider spectral coverage and higher spatial resolution in spectrometers, thereby enhancing the accuracy of data and the overall performance of the instrument. This large-sized grating plays an important role in fields such as astronomical observation, environmental monitoring, and high-end manufacturing, injecting strong impetus into scientific research and technological innovation.
The steel grating is a kind of iron and steel product with square grid in the middle, which is made of flat steel according to a certain distance and cross bar, and welded by pressure welding machine or manual. Steel grating is mainly used to make ditch cover plate, steel structure platform plate, steel ladder step plate, etc. The cross bar is generally made of twisted square steel.
Steel grating commonly used is 30 series and 40 series. Steel grating is generally made of carbon steel, and its surface is hot-dip galvanized to prevent oxidation. It can also be made of stainless steel and I-type flat steel. Steel grating has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other performance. The surface can be punched teeth to increase the anti-skid performance.
Advanced manufacturing technology ensures the flatness and precision of the steel grating surface. Strict quality control during the production process of steel grating ensures its uniformity and stability. The successful development of 5800×1000mm steel grating reflects a leap in industry technology and demonstrates the excellent innovation ability of the R&D team.
The widespread application of such large steel grating will significantly enhance the performance and efficiency of related equipment, driving technological advancements in more fields.
Welded Steel Grating: The most popular type, manufactured by electro-forging, where bearing bars and cross rods are welded to create a robust, permanent grid.
Press-Locked Grating: Features interlocking bars pressed together, ideal for architectural applications where a clean, smooth appearance is needed.
Heavy-Duty Grating: Utilizes deeper, thicker bearing bars to handle higher loads, suitable for high-traffic areas, vehicle loading, and large spans.
Plain：Our standard grating comprises plain square edge flat load bars, with a 6mm square twisted bar, forge welded on top of load bars. In steel grating there is a better slip resistance in patterns with 100mm cross rod centres.
Serrated：Another method for improving slip resistance is the use of serrated grating. The serrations are made up of small notches cut into the load bar during the slitting of the material.
Materials and Finishes
Carbon Steel: The most common and economical option.
Stainless Steel: Used for superior corrosion resistance in food processing, chemical, and marine environments.
Hot-Dip Galvanizing: The standard finish, applying a zinc coating to protect against rust, conforming to standards such as BS EN ISO 1461.
Common Applications
Industrial Flooring & Platforms: Walkways, catwalks, and maintenance platforms in plants.
Drainage Systems: Trench covers and sewer grates.
Stair Treads: Used for industrial staircases.
Architectural Screens: Fencing and decorative grilles.
Technical Specifications
Spacing: A common spacing is 19-4 (1-3/16" x 4"), offering ~80% open area.
Bearing Bar Thickness: Typically ranges from 1/8" to 1/2", with depths determined by load requirements.
Standard Sizes: Panels are often supplied in 1000mm x 6000mm.
Steel grating offers exceptional sustainability, as it is generally manufactured from recycled materials and is fully recyclable.
