Service and Maintenance

With many years of experience working in the industry DNA Products bring together an experienced workforce specializing in many products including Sliding, Hinged and High-Speed Doors.


A door with worn gaskets can be very costly when trying to keep a room at a low temperature. We can service all types of Sliding, Hinged, Steel and High-Speed Doors, Roller Shutters and Sectional Doors to prevent these extra and unnecessary costs.

We can replace Gaskets, Guide Rails, Handles, Locks, Hinges, Rollers and much more.


We can modify existing doors with upgrades like protective Kick Plates to prevent damage to your door leaf.


We can also fit new heaters to Sliding and Hinged doors in a freezer environment.


We can service or replace your Sliding Rail. Some of these can have bearings that wear over time.


We can replace damaged door leaves or supply an entirely new door with complete with frame if needed.

We also manufacture our own Universal Auto Kit which is available for installation to almost every Sliding Door track on the market to date, including Fermod Rails.

From a Health and Safety point of view this prevents you from having to physically open the door yourself and can increase efficiency with the Auto-Close feature.

See our Universal Auto Kit page for more information

Impact Damage

Doors do not fail simply because of wear and tear. Quite often we are called to site after a collision with a Forklift Truck or a wagon has led to severe damage of a door or loading bay area. Quite often this damage can prevent the door or dock leveller etc. from working properly. We can assess the safety of the existing products while taking measurements for replacement parts. We will try to match the colour of the existing products or the surrounding area if it is colour coded.
