Counterbalance System

A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation. The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.

Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings. Cable drums are also mounted on the spring shaft and carry the aircraft quality cables which have a 7:1 safety factor.

The cables are looped and fixed through the use of specialist machinery to make sure that all fixings stay connected in both, standard day to day operations and in more demanding circumstances throughout the working life of the doors. To ensure CE legislation is fully complied with, spring break devices are fitted.

Guide Tracks

The galvanised door tracks are manufactured and designed to ensure that the bearings run smoothly. This is done by mounting them on the galvanized steel angles for fixing, via HAG unique stud welding system which ensures the most secure seal to the building as the tracks need no adjustment on site. Cable brake devices fitted to all doors to comply with CE markings.

Guide Track Options

To ensure the perfect installation on site, all sectional door guide tracks are individually manufactured to suit site conditions as headroom and roof pitch will differ on each installation.


All HAG S Door sectional doors are sealed around all outer edges and intermediate panels to provide a superior and long-lasting weather seal when all fixing faces, floors & lintels are flush & square.
