Aluminium Gratings

Corrosion, weight, and installation time often challenge aluminium grating selection for infrastructure or architectural use. Our Aluminium Gratings address these with marine-grade alloys and open area up to 85% for drainage or airflow.

Panel Size (L × W)

Up to 6000mm × 1200mm (Custom sizes available)

Bearing Bar Thickness

2mm to 6mm

Bearing Bar Depth

20mm to 50mm

Bearing Bar Spacing

15mm to 50mm (Typical: 30mm, 34mm)

Cross Bar Spacing

50mm to 150mm (Standard: 100mm)

Overall Height/Thickness

20mm to 60mm (Depends on bar depth + joint design)

Product Description

They weigh as low as 5kg per square meter yet hold up to 3 Ton per square meter, reducing dead load without sacrificing strength. With slip-resistant surface variants and sizes up to 6000mm, these gratings support both long-span and compact-fit projects efficiently.

Open Area Percentage

60% to 85% (30mm spacing ≈ 75%)

Material Composition

Aluminium 6061-T6, 6063-T5, 5052-H32 (Marine grade: 5083/5086)

Load-Bearing Capacity

Up to 3 Ton/m² (30mm depth: ~1 Ton/m²; 50mm: ~2.5 Ton/m²)

Surface Treatment

Mill Finish, Anodized (Clear/Color), Powder-Coated, Anti-Slip Serrated

Edge Treatments

Plain, Banded (Al Flat Bar), Safety Nosing, Tooth Edges

Weight per m²

5kg to 25kg/m² (30mm depth ≈ 10kg/m²)

Compliance Standards

ASTM B221, EN 573, ISO 9001, OSHA

Corrosion Resistance

Excellent (Natural oxide layer; anodizing/powder coating enhances durability)

Temperature Resistance

-80°C to +200°C (Anodized); Up to +400°C (Uncoated, short-term)

Slip Resistance

R10 to R13 (Serrated), Smooth (Standard), Diamond/Gripper Patterns

Technical Advantages

Gratings often fail due to weak joints or low crossbar retention under repeated load. We use fusion-locked joints or mechanical swaging for permanent bar anchorage.

With aluminium 6061-T6 and 6063-T5 options, the material retains 85% yield strength even after surface treatment. Standard spacing of 30mm ensures pedestrian safety while maintaining over 70% open area.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can you confirm the weight range and how it impacts structural design?

Yes, our aluminium gratings range from 5kg to 25kg per square meter. This wide range helps structural teams reduce dead load, especially for retrofits or lightweight mezzanines. You can select thickness and bar depth based on the required load class.

How do you validate load-bearing claims during production?

We use pressure bench testing with point load and uniform load simulations across panel spans. Every lot undergoes verification using 30mm and 50mm bar depth samples. These reports are included with dispatch if requested during ordering.

Can you support large panel sizes without warping or deflection issues?

Yes, we manufacture up to 6000mm in length with banding or additional support ribs to control flex. Panel design includes deflection limits under static and live loads. We also provide suggestions on mid-span supports when required.

What surface finish works best for anti-slip access areas?

Serrated surfaces and diamond top bars both meet R10 to R13 slip ratings under DIN standards. Powder-coated or anodized finishes improve grip and also reduce dust settling. You can choose finish and slip level based on zone classification.

Are the gratings suitable for coastal or marine environments?

Yes, we offer 5052-H32 and 5083 aluminium for high chloride resistance. These marine-grade alloys prevent pitting and intergranular corrosion. You can also opt for anodized surface treatment for enhanced longevity in salt-laden air.
