Our factory door designs aim for absolute perfection

The value of our door designs lies in their extraordinary adaptability. Your factory’s unique qualities (which include the number of staff, traffic levels, location and weather, safety factors, and the purpose of the doorway) place equally unique demands on the personal access doors you need.

Our heavy-duty Sentry™ factory door designs boast extreme durability and come in wind and cyclone-rated designs. We offer hard-wearing finishes, including Colorbond®, galvanised and Zincanneal® steel, and corrosion-resistant MetaPrep™. And if you don’t find the perfect factory door? We’ll design and manufacture a one-off custom to your exact specifications.

The industry-leading versatility of Sentry™ factory doors

Our world-class designs are suitable for all factories, regardless of size, foot traffic levels or regulatory requirements.

Steel factory doors

If you’re after heavy-duty metal factory doors that can resist the daily stresses of your factory, our Sentry™ 200 series will solve your problems.

Industrial factory doors

When finished with MetaPrep™ primer for extreme corrosion resistance, our door designs are perfect for all industrial sites.

Factory garage doors

Our personal access doors provide easy staff access and vandal-proof security to protect your factory site’s vehicles and assets.

Factory security doors

The solid, robust designs of our Sentry™ factory doors provide exceptional site security and can be upgraded with heavy-duty locksets and automatic door closers.

Factory entrance doors

Factory doors need to be able to accommodate high traffic, especially in an emergency. Our doors can be outfitted with panic bars and high-security locksets.

Frequently asked questions

Do Larnec factory doors comply with workplace safety requirements?

Larnec factory doors are designed with workplace safety and access requirements in mind. Door configurations, hardware and installation methods can be selected to support relevant Australian Standards, including safe access, durability and escape requirements, depending on the application.

Are factory doors suitable for industrial environments with chemicals or fumes?

Factory doors are supplied with Colorbond metal cladding, which offers strong resistance to everyday industrial conditions such as overspray, airborne contaminants and general exposure common in factory environments. Suitability should be assessed based on the specific chemicals and site conditions involved.

Can factory doors be fitted with kick plates or impact protection?

Yes. Optional stainless steel kick plates can be added to help protect the lower section of the door in areas exposed to trolleys, pallet jacks, or frequent foot traffic?

What type of hinges are used on factory doors?

Factory doors are typically supplied with heavy-duty hinges, including stainless steel or galvanised options, selected to suit high-use industrial applications and door weights.

Do factory doors help reduce noise from machinery or production areas?

Solid-core, metal-clad factory doors can contribute to reduced noise transfer between spaces. Acoustic performance will vary depending on door construction, seals, and surrounding building elements.

Can factory doors be integrated with automation or access control systems?

Factory doors are supplied as manual doors as standard but can be specified to accommodate many third-party automation, access control, or security systems. Compatibility should be confirmed during the design stage.

Are threshold seals or bottom seals available for factory doors?

Yes. A range of bottom seals and threshold options can be added to improve draft control, dust reduction, and overall door performance, depending on site requirements.

Can factory doors be customised for different factory layouts or uses?

Factory doors can be configured in a variety of sizes, fixing methods to suit different factory environments, including manufacturing, warehousing, and processing facilities.
