Door Closers

Door closers are essential for safety, compliance, and reliability in commercial, residential, and strata settings. More than a finishing touch, a closer ensures controlled door operation—reducing impact damage, maintaining security, and meeting fire safety codes. Doric’s range of hydraulic door closers, automatic systems, and commercial-grade models are built for Australian conditions, tested to Australian Standards, and backed by decades of trusted supply.

When safety, compliance, and long-term value matter, choosing the right door closer is critical.

Types of Door Closers

Different environments demand different hardware. Doric offers options for every requirement:

Hydraulic Door Closers

The most common choice for high-traffic environments. Hydraulic fluid regulates the door swing, preventing slam and extending the life of both door and frame. Used widely in offices, schools, and shared entry points where reliability and quiet operation are key.

Automatic Door Closers

Integrate with sensors or access control systems to deliver convenience and accessibility. These are essential in healthcare, retail, and public spaces where hands-free operation and disability compliance are non-negotiable.

Commercial Door Closers

Engineered for endurance. With fire-rated models available, these are the standard for stairwells, exits, and main entry doors that must comply with the NCC.

Residential & Light Duty Door Closers

Compact solutions that provide everyday safety and convenience. Perfect for screen doors, side entries, and mixed-use sites where smaller-scale hardware is sufficient.

Maintenance & Replacement Guidance

Planned maintenance prevents costly failures and ensures compliance across sites:

Routine checks

• Clean bodies and arms to remove grit.
• Lubricate moving parts twice yearly with silicone spray.

• Regulatory updates requiring upgraded compliance.

Parts availability

Many Doric models support replacement arms, covers, and fittings, helping asset managers reduce lifecycle costs.

FAQs

Do fire doors require closers?

Yes. Under the NCC, fire-rated doors must be fitted with compliant closers to ensure they latch automatically.

How can door closers be adjusted?

Most units include valves for swing and latch speed. Adjusting these allows tuning for smoother closure without compromising security.

Can existing aluminium doors take overhead closers?

Yes. With the correct mounting plate and power size, overhead closers for aluminium doors are a standard solution in commercial fit-outs.

Are door closers compatible with access systems?

Yes. Doric closers can be integrated with strikes, card readers, and automation equipment.

Why upgrade older closers?

Upgrades reduce failure rates, improve compliance, and cut down on ongoing repair budgets.
