Heavy-Duty Steel Grating Solutions for Industrial Platforms, Walkways and Infrastructure Projects
Steel grating is composed of bearing flat bars and cross bars, which are arranged orthogonally at fixed intervals and connected through welding or press-locking techniques. This open-grid structure combines both strength and flexibility, making it ideal for applications that require high safety and performance standards. Its robust design has made steel grating the preferred choice for various industries, including construction, mining, and manufacturing, where reliability and durability are essential. Trusted for its exceptional quality, steel grating is a go-to material for demanding environments and critical infrastructure.
Welded Steel Grating
Our Type "W" Welded Steel Gratings are made by forge welding rectangular bearing bars to drawn cross bars, creating a strong, fused connection that ensures long-lasting performance, even in the toughest environments.
The 19-W-4 spacing is our most popular choice and is ideal for a wide range of industrial flooring applications. Offering nearly 80% open area, it allows dirt, debris, snow, and liquids to pass through easily, making it essentially self-cleaning.
For public spaces, we offer ADA-compliant spacings such as 11-W-4 and 7-W-4. These gratings are designed to meet accessibility standards. When selecting 11-W-4 for ADA applications, it's important to specify bearing bars that are 3/16” thick to ensure compliance.
Swage Locked Steel Grating
Type "SL" Steel Gratings are produced by inserting hollow tube cross bars into pre-punched holes in the bearing bars. These cross bars are then hydraulically compressed, creating a strong mechanical connection. The recessed cross bars sit below the surface of the bearing bars, giving the grating a sleek and uniform architectural look.
The swage locking process is particularly effective for producing ADA-compliant gratings. For example, the 7-SL-4 type, featuring 3/16" thick bearing bars, creates a 1/4" clear opening between the bars. This narrow spacing is ideal for public spaces where pedestrian traffic includes high heels, and efficient drainage is required.
Dovetail Pressure Locked Steel Grating
Type "DT" Steel Gratings feature deep rectangular cross bars and are created by inserting pre-punched bearing and cross bars into an "egg-crate" pattern. The cross bars are then deformed under high hydraulic pressure to form a strong, secure connection.
The distinctive deep cross bars make Type "DT" gratings especially popular for architectural applications, such as sunshades and infill panels. The deeper bars not only enhance the grating’s strength but also add a unique architectural accent to any design.

Standard Trim Banding
Standard Trim Banding The band bar matches the exact height and thickness of the bearing bars, creating a consistent, flush finish on all sides of the panel. This is the most common choice for general applications.
Trench Banding
The band bar is intentionally shorter than the bearing bars, sitting slightly above the bottom edge. This design improves drainage by preventing liquid from pooling between the grating and support structures — ideal for drainage trenches, gullies, and wet areas.
Banding is a practical and popular finishing option that adds both strength and a clean, professional look to your steel grating panels. It involves welding a flat metal bar along the open ends of the grating, creating a framed edge that significantly improves lateral stiffness and protects the cut ends.
Steel Grating Projects Requiring Edge Banding
We recommend banding for the following situations:
Removable Panels: Provides extra safety for workers when lifting or moving panels.
Vehicular Traffic Areas: Helps distribute impact loads, reduces deformation, and extends the service life under repeated vehicle traffic.
Architectural & Visible Installations: Delivers a neat, uniform appearance suitable for commercial and public projects.
Heavy Duty Steel Grating for High Load Applications
Designed for demanding environments, heavy duty steel grating features reinforced bearing bars and optimized load-bearing structures to handle higher static and dynamic loads. It is widely used in ports, airports, highways, mining facilities, power plants, and heavy industrial areas with frequent vehicle or equipment traffic.
Our engineering team evaluates load requirements, span conditions, and application environments to recommend suitable bar sizes, spacing configurations, and fabrication methods, helping customers achieve safe and cost-effective solutions for heavy-duty projects.
Standard Steel Grating for Industrial Applications
Our standard steel grating solutions are manufactured for industrial flooring, walkways, platforms, drainage covers, and maintenance areas where strength, safety, and durability are required. With precise control of bearing bar dimensions, cross bar spacing, and surface treatment, we provide reliable grating solutions that meet different load requirements and installation conditions.
Custom Fabrication for Complex Project Requirements
Beyond standard sizes, we provide customized steel grating fabrication based on customer drawings, load calculations, and installation requirements. Our manufacturing capabilities include cutting, edge banding, surface treatment, stair treads, kick plates, cut-outs, and special shapes for complex industrial applications.
