AW 5754 H114 Aluminium Tread Plate

AW 5754 H114 Aluminium Tread Plate: The Definitive Marine-Grade Flooring Solution

In the world of industrial aluminium, few alloys match the versatility, durability, and performance of EN AW-5754. When combined with the H114 temper and a raised diamond or five-bar tread pattern, this material transforms into one of the most reliable non-slip flooring solutions available on the global market. At Gwangyang Aluminum (GYAL), we manufacture premium AW 5754 H114 aluminium tread plate—often referred to as chequer plate, diamond plate, or floor plate—engineered to excel in the most demanding environments, from offshore platforms and chemical plants to heavy-duty vehicle flooring.

What is AW 5754 H114? Understanding the Specification

Alloy 5754: The Al-Mg Marine-Grade Standard

EN AW-5754 is a non-heat-treatable aluminium-magnesium alloy belonging to the 5000 series, containing approximately 2.6–3.6% magnesium as its primary alloying element. This composition gives 5754 its exceptional properties:

Magnesium (Mg): 2.60–3.60%—provides high strength and superior seawater corrosion resistance

Manganese (Mn): 0.00–0.50%—enhances solid solution strengthening

Chromium (Cr): 0.00–0.30%—improves corrosion resistance and grain structure control

Iron (Fe): ≤0.40%, Silicon (Si): ≤0.40%—controlled impurities for consistent performance

The H114 Temper: The Standard for Tread Plate

The H114 temper is a specialized designation unique to tread plate applications. The H114 temper provides superior corrosion resistance and excellent strength compared to other temper conditions (such as H12 or H22). H114 represents a specific processing route for rolled aluminium that is particularly suitable for applications requiring high strength and outstanding atmospheric corrosion resistance.

In practice, H114 is the temper most commonly associated with aluminium chequer plate, alongside H111, making it the industry standard for non-slip flooring products.

Key Properties of GYAL AW 5754 H114 Tread Plate

Mechanical Performance (per BS EN 485-2:2008)

For 5754 H114 sheet in the 0.2mm to 6.00mm thickness range, GYAL delivers the following certified mechanical properties:

Note: The mechanical properties shown above are specifically for the H114 temper.

For comparison, the softer H111 temper delivers lower proof stress (60 MPa Min) and tensile strength (160–200 MPa), while the harder H22/H24 tempers offer higher strength but reduced elongation

Physical Properties

The Tread Pattern: Engineered for Superior Slip Resistance

AW 5754 H114 aluminium tread plate is manufactured with a raised pattern on one side, most commonly the five-bar diamond pattern (also known as five-rib or chequer plate design). This pattern provides exceptional slip resistance in all directions, making it ideal for:

Loading ramps—prevents slipping during vehicle loading and unloading

Dock flooring and trench covers—excellent grip in wet and oily conditions

Stair treads—safety-critical applications where falls must be prevented

Vehicle flooring—car, truck, ambulance, and fire truck floor protection

The raised pattern maintains consistent bar height across the entire sheet, with minimum heights of 0.6mm for thicknesses between 1.1mm and 2.0mm, and 0.8mm for thicknesses between 2.0mm and 10.0mm.

Performance Advantages of AW 5754 H114

1. Exceptional Marine-Grade Corrosion Resistance

5754 aluminium is widely recognized as a marine-grade alloy due to its outstanding resistance to seawater corrosion. The magnesium content enables the formation of a stable, self-healing oxide layer that actively resists chloride attack. Key performance highlights include:

Excellent resistance to seawater—ideal for shipbuilding, offshore platforms, and coastal infrastructure

Superior performance in industrially polluted atmospheres—withstands chemical and nuclear environments

Resistance to industrial chemicals—suitable for chemical processing facilities

2. High Strength-to-Weight Ratio

With tensile strength up to 260 MPa and density just 2.66 g/cm³, 5754 H114 tread plate offers a superior strength-to-weight ratio compared to many other aluminium alloys. This translates to:

Reduced structural load—lighter floors and walkways require less support

Improved fuel efficiency—in vehicle flooring applications

Easier handling and installation—reduces labour costs and improves safety

3. Excellent Weldability and Formability

5754 H114 tread plate offers outstanding fabrication characteristics:

Gas welding: Excellent

Arc welding: Excellent—suitable for MIG and TIG processes

Resistance welding: Excellent

Cold workability: Very good—can be formed without cracking

Note: Brazability is rated as poor.

4. Suitable for Pressure Vessel Applications

EN AW-5754 in O and H111 conditions is certified for use in pressure vessels and piping in accordance with EN 12392, with a working temperature range of -273°C to +100°C. This makes it suitable for cryogenic applications in the LNG and industrial gas sectors.

5. Anodizing Quality for Enhanced Finishes

5754 is suitable for decorative anodizing, offering good colour match and excellent surface finish quality. This allows for:

Enhanced corrosion protection through anodized coatings

Aesthetic finishes for architectural applications

Improved wear resistance for high-traffic areas
