Why Aluminum Louvers?
The major advantages of fabricating aluminum louvers are aluminum’s low cost and ease of maintenance. Aluminum louvers will be light and durable and yet with aluminum’s high strength to weight ratio they will still offer sufficient strength for many applications. On average, an aluminum louver is lighter by as much as two thirds compared to a counterpart in steel or stainless steel. Aluminum louvers will not rust. Aluminum is however, less strong than steel and so might not be selected for some heavy-duty applications. In high temperatures, aluminum expands twice as much as steel and this may be also be a factor in deciding which material should be used for your louver depending on your particular application. Aluminum alloys used by EMW include the 3000 series (Al-Mn, on the softer side and with good corrosion resistance), the 5000 series (Al-Mg, higher strength) and the 6000 series (Al-Mg-Si, heat treatable with good properties of both strength and corrosion resistance).
