Choosing the right material for industrial louvers is a crucial decision for any construction or commercial project. Louvers don’t just control airflow—they also affect durability, maintenance costs, and even the overall weight of your building’s ventilation system. Two metals dominate the market: aluminium louvers and steel louvers. Let’s break down the pros and cons of each to help you make an informed choice.
Aluminium Louvers – Lightweight, Durable, and Corrosion Resistant
Aluminium is widely considered the superior material for louvers, and for good reason:
- Lightweight: Aluminium weighs roughly one-third of steel. This makes handling, installation, and supporting structure requirements much easier. For example, a 10-meter louver panel in aluminium can weigh as little as 30 kg, whereas the same steel panel might weigh 90 kg.
- Corrosion Resistance: Aluminium naturally forms a thin oxide layer that protects it from rust, even in humid or coastal environments. This means less maintenance and longer life.
- Recyclability and Scrap Value: Aluminium is highly recyclable, retaining 90–95% of its original value. In India, aluminium scrap can fetch around ₹120–150 per kg, making end-of-life disposal both eco-friendly and profitable.
- Ease of Fabrication: Aluminium louvers are easy to cut, shape, and assemble without heavy-duty machinery, making them ideal for custom metal louvers and intricate designs.
Steel Louvers – Strong but Heavier and Maintenance-Intensive
Steel louvers are a strong alternative but come with trade-offs:
- Weight: Steel is significantly heavier than aluminium, roughly three times the weight for the same size panel. This adds structural load and increases installation effort.
- Corrosion Risk: Steel needs galvanization or protective coating to resist rust. Without it, steel can deteriorate in just a few years in harsh environments.
- Lower Scrap Value: Steel scrap is abundant but less valuable than aluminium, fetching around ₹20–25 per kg in India. Recycling steel is important but doesn’t provide the same financial incentive.
- Maintenance: Regular painting or coating is required to prevent corrosion, adding ongoing costs over the louver’s lifespan.
Cost vs Lifecycle Value
While steel louvers may seem cheaper upfront, aluminium often provides better long-term value:
| Feature | Aluminium | Steel |
| Weight | 1/3 of steel | Heaviest option |
| Corrosion Resistance | Excellent | Requires coating |
| Maintenance | Minimal | Moderate to High |
| Scrap Value | ₹120–150/kg | ₹20–25/kg |
| Recyclability | 90–95% | ~60% |
| Lifespan | 25+ years | 10–15 years (coated) |
The aluminum louver is like a marathon runner—light, long-lasting, and low maintenance. Steel louver is more like a powerlifter—strong but heavy, requiring more upkeep and energy to keep performing.
Which Should You Choose?
- Use Aluminium louvers if your project demands lightweight, corrosion resistance, long-term savings, and higher scrap value. Perfect for commercial buildings, coastal structures, and high-performance ventilation.
- Use Steel louvers if your priority is heavy-duty strength at a lower initial cost, and the environment is less aggressive. Suitable for industrial facilities where weight isn’t a concern.
