Our polycarbonate multiwall garage doors feature impressive impact resistance with the following:

  • Outstanding impact performance over a wide temperature range, -40°C to +120°C
  • Impact strength is 250 times higher than glass.

A reliable garage door is essential in Australia, where temperatures and weather conditions can be extreme at any time of the year. A Steel-Line polycarbonate multiwall garage door has two sides of UV resistance, which provides:

  • Greater design flexibility
  • Superior resistance to outdoor weathering
  • Finger proof safety

With all these advantages, it’s easy to see why this type of garage door is quickly gaining popularity among homeowners throughout Australia.

Other Features

Steel-Line’s polycarbonate multiwall garage doors have excellent energy efficiency. The multiwall construction enables air to get trapped between each layer, which leads to outstanding thermal insulation. This natural insulation could save you from turning your car’s air conditioning or heating to full blast before leaving home in the morning!

These models are also incredibly lightweight despite their strength. An outstanding balance of low weight and high stiffness enables us to design lightweight structures with greater spans. This is just another example of how Steel-Line combines high-quality materials with innovative construction techniques to deliver the best possible products for our customers.
