Self closing doors shut on their own after someone passes through – keeping an entrance secure, energy-efficient and safe without anyone having to pull it closed. From automatic sliding and swing doors to spring-loaded and closer-fitted hinged doors, self closing doors are everywhere in shops, clinics, offices and public buildings. This 2026 guide explains how these doors work, the types available, and how Coetz supplies, installs and services them across South Africa.
If you want a door that opens and closes on its own, see our guide to the automatic door closer options.
How self closing doors work
Self closing doors use a mechanism that returns the door to the closed position after opening – a hydraulic or spring closer on a hinged door, or a powered operator on an automatic door. On automatic entrances the operator holds the door open for a set time, then closes it gently under control, set up to recognised automatic door technology safety principles so it never closes on anyone in the way.
Types of these doors
Self closing doors come in a few forms to suit the opening and use:
- Automatic sliding doors – slide open on sensors and close behind you.
- Automatic swing doors – a powered swing door operator opens and closes the leaf.
- Door-closer hinged doors – a hydraulic closer returns the door to closed.
- Spring-hinge doors – a sprung hinge pulls the door shut.
Why use self closing doors?
Self closing doors deliver real benefits beyond convenience:
- Security – the door is never left open by accident.
- Energy efficiency – keeps conditioned air inside and cuts running costs.
- Hygiene and comfort – keeps dust, insects and noise out.
- Fire safety – fire-rated these doors help contain smoke and flames.
- Accessibility – hands-free automatic self closing doors suit everyone.
