Aluminum bar grating is an open-mesh structural panel manufactured from high-strength aluminum alloy bearing bars and cross bars, mechanically or adhesively joined to form a rigid grid. It delivers the structural performance of metal bar grating with properties that steel cannot match: natural oxide-layer corrosion resistance, non-sparking characteristics in flammable environments, non-magnetic behavior around sensitive equipment, and a clean architectural appearance that complements modern industrial and commercial design.

CANRI WIRE MESH offers many options for aluminum bar grating, such as: swaged rectangular bar,flush top, press lock, riveted, plank, and I-bar aluminum bar grating products.

Whether you are building offshore platforms, chemical plant walkways, or architectural facades, our aluminum grating panels provide long-lasting performance with zero maintenance requirements.

Lightweight yet strong, our aluminum grating is the ideal choice for pedestrian walkways and corrosive environments.

1. Corrosion Resistance – Ideal for corrosive environments (e.g., chemical plants, wastewater treatment, marine applications) where traditional steel grating fails.  

2. Lightweight and High Strength– Up to 70% lighter than steel but with comparable load-bearing capacity, reducing installation and structural support costs.  

3. Slip-Resistant Surface – Molded with grit-coated or patterned surfaces for enhanced safety in wet/oily conditions.  

4. Non-Conductive and EMI Transparent – Safe for electrical hazards and compatible with sensitive RF/communication equipment.  

5. Low Maintenance – No painting or galvanizing required, with long-term cost savings.  

6. Customizable– Available in various mesh sizes, thicknesses, colors, and resin types to meet specific load/chemical exposure needs.  

Aluminum Bar Grating vs. Steel Grating — Complete Comparison

Why Buyers Select Aluminum Bar Grating?

Aluminum bar grating is normally selected when a project needs an open-grid walking or screening surface but excessive structural weight would increase fabrication, lifting or installation costs.

Its low density can reduce dead load on elevated catwalks, maintenance platforms, roofs, pedestrian bridges and modular access systems. Its naturally formed surface oxide provides corrosion resistance in many wet and outdoor environments without depending on galvanizing or routine repainting.

The open-grid construction permits drainage, ventilation and the passage of light. Removable panels also provide access to equipment, channels and services below.

This material is especially useful where buyers need:

• Easier manual handling and installation
• Lower weight on supporting structures
• Corrosion resistance in compatible environments
• Clean lines for visible architectural applications
• Non-magnetic and non-ferrous construction
• Custom panel fabrication for complex layouts
• Recyclable metal content and reduced coating maintenance

Aluminum is electrically conductive. It must not be described or specified as a non-conductive substitute for fiberglass grating.

At Canri Steel, we understand that every project is unique. We manufacture and supply a wide variety of configurations to meet your specific load requirements:

Type 1:Swage locked aluminum grating

The swage locked rectangular bar, the most commonly used aluminum grating, features clean lines. Its bearing bars come with standard plain surfaces, and optional serrated surfaces are also available. The cross bars are completely locked into the bearing bars, positioned slightly below the top surface.

Type 2: Swage locked I bar aluminum grating

The I bar grating has lighter weight than rectangular bar and is a great option for any project that has weight limit restrictions.High strength,slip resistant bearing bars and low cost making the grating and excellent choice.

Type3: Swaged flush top aluminum grating

Swaged flush top aluminum grating is produced using a distinctive extruded cross bar that aligns evenly with the top surface of the bearing bars. This design offers an improved walking surface, making it ideal for areas with constant pedestrian movement.

Type 4: Dovetail pressure locked grating

Dovetail pressure locked aluminum gratings are characterized by their deep rectangular cross bars. They are fabricated by arranging pre - punched bearing bars and cross bars in an “egg - crate” pattern and then deforming the cross bars through high - pressure hydraulic processes.

The prominent deep cross bars of this gratings render them highly sought - after in architectural uses like sun shades and infill panels. The depth of these cross bars acts as a striking visual feature, enhancing the aesthetic appeal of the structures.

Surface Options for Aluminum Bar Grating

Smooth / Plain Surface
Standard surface for aluminum bar grating in indoor environments, architectural applications, and any installation where a clean, unobtrusive appearance is required. Provides adequate traction for dry pedestrian environments.

Serrated Surface
Bearing bar top edges are notch-cut to create a saw-tooth pattern that increases friction and traction under wet, oily, and contaminated surface conditions. Recommended for all outdoor aluminum bar grating applications, food processing plants, marine decking, wash bays, and any surface exposed to liquid.

Grooved Surface (I-Bar type)
The top flange of I-bar bearing bars is extruded with longitudinal grooves that provide multi-directional traction. Standard on Type SGI aluminum grating.

OnGrip™ / Applied Grit
Abrasive grit particles bonded to the top surface. Maximum traction for environments with extreme slip hazard — used where serrated surface alone is insufficient.

Custom Aluminum Walkway and Catwalk Solutions

Aluminum walkway grating is purchased as part of a complete access system, not as an isolated panel.

A successful walkway package should coordinate the support spacing, panel joints, fixing clips, guardrails, toe plates, stairs, landings and site-installation sequence.

For elevated or modular structures, lower panel weight can simplify lifting and reduce the permanent load carried by the supporting frame. For outdoor access, drainage and traction must be considered together. For public areas, opening size and walking comfort may be more important than maximum open area.

Canri can review drawings for:

• Industrial access walkways
• Elevated equipment catwalks
• Roof maintenance paths
• Water and wastewater platforms
• Pedestrian bridge decking
• Marine and dock access areas
• Cooling-tower and utility access
• Modular skid and packaged-equipment platforms
• Architectural walkways and entrance grilles

Our aluminum walkway grating is trusted by engineers worldwide for diverse applications:

Stair Treads & Ramps

When adding a mezzanine floor or elevated walkway to an existing structure, minimizing added dead load on the supporting framework is often a critical structural constraint. Aluminum bar grating panels at one-third steel weight allow mezzanine projects to proceed within existing structural capacity that would be exceeded by steel grating — often eliminating the need for structural reinforcement.

Water and Wastewater Treatment Facilities

Continuous exposure to moisture, hydrogen sulfide, chlorine compounds, and biological effluent makes conventional galvanized steel grating a maintenance liability in water treatment plants. Aluminum bar grating handles these conditions without coating failure, rust staining, or structural deterioration. 6063 alloy with serrated surface is the standard specification for platform flooring in water and wastewater treatment.

Marine and Offshore Environments

Aluminum bar grating is the dominant grating material for marine dock decking, boat landing stages, offshore platform walkways, and shipboard flooring. The combination of lightweight (reducing vessel deck load), inherent salt-air corrosion resistance (no galvanizing required), and non-magnetic properties makes it far superior to steel in marine applications.

Food Processing and Pharmaceutical Manufacturing

Aluminum bar grating meets food-safe hygiene requirements: it is non-toxic, non-contaminating, and resistant to the cleaning chemicals and steam washdown used in food processing environments.
