Welded Steel Grating
Welded steel grating plates are cost-effective and durable platform sheet products.Its common combination form is to weld the crossbars and rectangular load-bearing flat steel to create a stable and reliable main structure. Due to its high load-bearing capacity and excellent drainage performance, it can still be used for many years even in harsh outdoor environments.
The mainstream model 19-W-4 welded steel grating plate features a high hollowing rate design, which can quickly drain water, waste residue, snow, and various liquids. It is suitable for industrial platforms, maintenance passages, and ground laying. The 11-W-4 and 7-W-4 specifications of steel grating plates are commonly used in public areas and pedestrian passages, with a safer grille gap design.
Royal Group can customize the processing of welded steel grating plates. Specifications, raw materials, and surface treatment methods can all be selected as per requirements. Hot-dip galvanizing and stainless steel materials are available options.
Swage Locked Steel Grating
Swage Locked Steel Grating Swage Locked Steel grating is a durable, yet versatile floor solution made by inserting be hollow tube cross bars into pre-punched bearing bars and then locking the two with a unique mechanical swaging process. Ideally suited for both industrial and architectural applications due to its high load capacity, architectural appearance, and structural stability.
The very popular 7-SL-4 swage locked steel grating has narrow openings for use in general areas and is commonly used in the public areas, sidewalks, and platforms where good holds for pedestrians and drainage is a must.
Royal Steel Group can provide customized swage locked steel gratings with different sizes and grades of materials with or without surface finishing such as hot-dip galvanizing, painting or gave in stainless steel.
Dovetail Pressure Locked Steel Grating
Dovetail Pressure Locked Steel Grating is based on the standard pressure locked system and can be up to 2 1/2 times the bar depth in thickness! It is assembled by pushing standard pre-punched bearing bars and rectangular cross bars into an “egg-crate” shape and then pressing them at high hydraulic strength to create a powerful mechanical joint. This process yields superior stability, load capacity, and a crisp architectural look.
The distinctive visual effect between the deep cross bars of Type “DT” steel grating and its closely spaced bearing bars make it a unique architectural solution for sunshades and facades as well as infill panels, platforms and decorative structures.
Royal Steel Group offers tailored dovetail pressure locked steel gratings in different dimensions, materials, and surface treatments such as hot-dip galvanized and stainless steel options.
Surface Type
The steel grating plates with a flat surface are characterized by a smooth and flat surface, excellent load-bearing performance, and are commonly used in industrial platforms, walkways, and regular flooring scenarios.
The bearing bars of the steel grid plate with a toothed surface have strong anti-slip properties and a high safety factor, making them suitable for humid, oily or high-risk working environments.
The steel grating with anti-slip surface adopts a specially designed anti-slip structure, which has greater friction force. It is suitable for areas with heavy loads and dense foot traffic, thereby enhancing traffic safety.
Surface Finish
The steel grating plate on the original surface is made of carbon steel base material and is delivered in its factory-original color through hot rolling process; no additional coating is applied. After welding or processing, the surface may show color changes.
The hot-dip galvanized steel grating is treated with zinc immersion in accordance with the ASTM A123 standard, providing long-term rust prevention protection.
The painted steel grating is coated with a layer of factory-standard topcoat. The common colors available are black, red and silver.
Steel Grating Banding
Standard Trim Banding
The edge strips of the standard edge-finished steel grating are welded at the ends of the grating plate, with their height matching that of the load-bearing flat steel, ensuring that the appearance of each surface of the grating plate is uniform and consistent.
Trench Banding
The edge banding of the steel grating with groove-type edge treatment is lower than the load-bearing flat steel. It narrows upwards from the bottom of the load-bearing flat steel. This edge treatment method has better drainage performance, and liquids will not accumulate between the support and the grating.
Bar Grating Fabrication and Engineering
Royal Steel Group provides professional bar grating fabrication and engineering services including custom cutting, banding, welding and surface finishing. Our expert staff can deliver the right solution to your grating questions whether from your project drawings, load requirements or environmental conditions and offer you solutions with proven performance for platforms, sidewalks, stairs and infrastructure for industrial applications and civil works.
Application
Steel grating is popular for use in the industrial, commercial, and infrastructure markets because of its strength, long life and good drainage characteristics. Typical applications include:
Industrial Platforms & Walkways – Safe and long-lasting walking surfaces in manufacturing facilities, industrial plants, and shops.
Stair Treads & ramps – Ensures safe pedestrian traffic with high load capacity and anti-slip performance.
Petrochemical & Power Plants – For operating platforms, maintenance walkways, and equipment access.
Oil & Gas Facilities – Oil platforms, refineries and pipelines among others.
Water Treatment Plants – As drainage covers, walkways and service platforms.
Steel Structure Buildings & Warehouse - Can be used for flooring system,office floors ,maintenance plats.
Bridges & Transportation Infrastructure - Capturing the right balance of superior strength, rigidity, and lightweight.
Architectural Applications – For facades, sunshades, decorative panels, and other building elements.
Royal Steel Group provides tailor-made steel grating products for industrial, energy, building and infrastructure projects worldwide.
