Sliding Door Technical FAQS

Yes, the Marathon system has a fire door set available. We can also offer systems as special order.

We recommend using continuous floor channel on all commercial applications and doors over 1000mm wide on domestic applications.

When there is insufficient strength in the head of the opening to carry the weight of the door.

Yes, most have test certificates to BS or EN standards. Generally partition systems have testing of 200,000 open and close cycles, and furniture systems are tested to 40,000 cycles.

Yes, most furniture systems have this option and some partition door systems now also have an option.

This is not recommended.

Sorry we do not offer an installation service.

No, we don’t supply the actual doors, but we do supply any associated ironmongery.

A system which is specified correctly will not require a great deal of maintenance. Most industrial systems will require the track and hangers to be greased every six months. Commercial systems require no greasing but benefit from having the track, and any guide channel, cleared of obstruction and dirt build up. All systems should have their fixings checked for tightness every six months.

The standard number of hangers for a straight sliding system is two. Adding an additional hanger will not increase the allowable door weight as the weight will only ever be carried on two hangers. The number of hangers required for a folding system is determined by the number of doors to be used.

The most important consideration is the weight of the door. Other factors which are important are the height of the door, the number of doors required, whether the application is internal or external, is there strength in the head of the opening to carry the door weight and is there room for the doors to be parked at the side of the opening. Environmental circumstances are also important e.g. is it to be used in a high use environment such as a school or hospital, will the gear be exposed to corrosive elements etc.
