What is 7075 Aluminium?
7075 is a zinc-dominated alloy from the 7xxx series, known for its exceptional strength. First developed for aircraft manufacturing, it combines zinc with magnesium and copper to produce a high-strength aluminium alloy with excellent mechanical properties. The chequered variant includes raised patterns that offer grip and safety, making it useful in structural and flooring solutions.
Benefits of 7075 Aluminium Chequered Plates
1. High Strength-to-Weight Ratio
One of the strongest aluminium alloys available commercially, 7075 provides nearly the strength of some steels while being significantly lighter. This makes it ideal for weight-sensitive applications like aircraft flooring or military vehicles.
2. Superior Fatigue Resistance
Unlike many materials that fail over time due to cyclic loading, 7075 resists fatigue exceptionally well. This property ensures a longer lifespan even in areas subject to repeated mechanical stress.
3. Enhanced Grip and Safety
The chequered pattern—whether five-bar, diamond, or customized—provides superior slip resistance. This is particularly valuable in areas exposed to oil, moisture, or heavy foot traffic.
4. Good Corrosion Resistance (When Treated)
Although raw 7075 aluminium has moderate corrosion resistance, it can be anodized or treated for excellent protection against rust and environmental damage.
5. Workability and Machinability
Despite its strength, 7075 chequered plates can be machined, formed, and drilled under proper conditions. This workability makes it suitable for custom fabrication.
6. Long-Term Durability
Designed for rugged environments, these plates retain their form and integrity for years, even under mechanical, thermal, or environmental stress.

Sustainability and Environmental Considerations
Aluminium is infinitely recyclable, and 7075 is no different. Scrap or offcuts from chequered plates can be melted and reused without compromising quality. This reduces environmental impact and supports circular manufacturing.
Moreover, lightweight materials like 7075 contribute to fuel efficiency in transportation and logistics—lowering emissions and operational costs.
Design Flexibility and Customization
7075 chequered plates are available in various thicknesses, lengths, widths, and surface patterns. This allows manufacturers and engineers to select exactly what they need without over-specifying or overpaying.
Common chequer patterns include:
- Five-bar tread
- Diamond tread
- Custom grip designs for specific applications
Custom fabrication—such as pre-cut holes, beveled edges, or folding—makes it even easier to incorporate into modular systems.
Maintenance and Service Life
When properly treated and maintained, 7075 chequered plates offer excellent longevity. They require minimal upkeep:
- Periodic cleaning with mild, non-abrasive cleaners
- Occasional checks for corrosion (if exposed to salt or chemicals)
- Surface refinishing or anodizing as needed
This makes them ideal for facilities that prioritize both safety and cost-effective operations.
Limitations to Be Aware Of
While 7075 aluminium chequered plates are high-performing, users should consider:
- Weldability: 7075 is not easily weldable due to the risk of cracking. If welding is essential, alternate grades may be better.
- Cost: As a premium alloy, it is priced higher than many others.
- Corrosion Resistance: Requires treatment in harsh environments to maintain appearance and performance.
However, in applications where strength, fatigue resistance, and reliability are more important than weldability or initial cost, 7075 shines.
The Growing Demand for 7075 Chequered Plates
As industries evolve to demand higher standards for material performance, the demand for advanced alloys like 7075 continues to rise. Aerospace firms, defense contractors, infrastructure developers, and industrial engineers increasingly rely on this alloy to meet safety and efficiency goals.
From energy infrastructure to precision transport equipment, its capabilities open doors to new design possibilities.
Conclusion
7075 aluminium chequered plates represent a premium, high-performance solution in environments where failure is not an option. With their superior strength-to-weight ratio, fatigue resistance, and anti-slip safety design, these plates are used across industries ranging from aerospace and defense to logistics and infrastructure.
Their recyclability and long service life add to their value, making them both an economical and environmentally sound investment. By choosing 7075 aluminium chequered plates, manufacturers and engineers ensure robust, safe, and forward-looking solutions for even the most demanding applications.
If you are exploring durable, high-strength aluminium materials for your next project, 7075 chequered plates are a choice that delivers confidence, performance, and longevity.
