Alutech offers two types of garage doors differing in the leaf balance system.
Maximum size of this type of doors is 6000 x 3085 mm.
Leaf balancing is achieved by torsion springs located above the door leaf.
There are three types of garage doors mounting (low, standard, and high) which allow to install Classic garage doors almost in every opening.
|Standard mounting||Low mounting||High mounting|
To mount Classic garage doors the headroom height should be not less than 100 mm for manual control, and 125 mm for electric drive control.
Maximum size for Standard garage doors is: width – 3,500 mm, height – 3,085 mm.
A distinctive feature of this type of doors is that leaf balancing is achieved by tension springs. Tension springs ensure easiness of the door movement and prevent their spontaneous lowering.
The tension springs in the Standard type of doors are located between the door leaf and vertical tracks, two on each side.
Use of this type of springs significantly reduces mounting time. The door mounting process usually takes 2.5 – 3 hours from the start of mounting to the moment when the product is accepted by the customer.
Sectional doors of the Standard type can be mounted almost in every garage opening. A 100 mm headroom height is required for their mounting, which is very convenient in case when old iron hinged doors are replaced by up-to-date Alutech sectional doors.
