Quality Features That Will Stand The Test Of Time

For many years Steel-Line’s range of garage doors has set the benchmark for style and quality throughout the Australian garage door industry. Most Steel-Line sectional garage doors can be automated for ease of use. As a market leader in safety and innovation, all of SteelLine’s automatic garage door openers come with a range of safety features. The standard ‘Auto Reverse System’ causes the garage door to immediately stop and reverse when it comes into contact with an object, while the optional ‘Photo Eye‘ feature automatically reverses the closing garage door if its electronic beam senses an obstruction. Furthermore, to ensure smoothness of operation and one of the quietest garage door mechanisms available, Steel-Line uses specially designed composite nylon and steel hinges

FingerProofTM Safety

Steel-Line’s sectional garage doors feature a curved finger proof joint for added safety. This unique award-winning design not only safeguards your family against serious injury, it seals out elements that can penetrate
conventional garage doors.

Heavy Duty Bottom Rail

Every Steel-Line sectional garage door is fitted with a sturdy heavy duty bottom rail to increase strength in the lower part of the garage door. A tough and durable weather seal is added to the bottom rail for extra protection from the elements.

Strong and Quiet Operation

To avoid the harsh sounds of metal-on-metal, Steel-Line uses hinges made of specially designed composite materials such as nylon for smooth, quiet and trouble free operation.
