The Complete Guide to Choosing the Right Door for Your Industry

At Larnec, we know that not all doors are created equal — especially in industries where durability, security, and compliance are non-negotiable. From the dust of remote mining sites to the strict escape function compliance in commercial and industrial buildings, every sector has unique requirements.

Choosing the right door can improve safety, reduce maintenance costs, and keep operations running smoothly. In this guide, we’ll match the right Larnec door type to the right industry so you can make an informed investment that lasts.

1. Construction & Warehousing

For commercial and industrial projects, you need a versatile door solution that works across a range of wall types and installation methods.

Larnec’s Sentry™ 100 Series is a fully metal-clad industrial door that suits multiple wall thicknesses and wall types, including timber stud, steel framework, and pre-cast panel. This multi-purpose solid core door is pre-hung for quick installation, saving you time and money on site.

For tilt panel construction, our tilt panel door system is purpose-built — dual-skin, metal-clad, and prepped for locks, with our own dual quad fastening system. These doors can also be retrofitted with ease, eliminating the need to pre-cast the jamb. No external fixings or internal finishings are required, making them the perfect fit for fast, clean installs.

2. Mining & Remote Sites

Remote and mining environments demand durability and weather protection. Larnec’s modular building doors are designed for site offices and facilities in these challenging locations, with options for superior weather sealing to keep out dust, wind, and rain.

Quick to install and available in custom sizes, these doors meet the unique demands of mining operations while helping maintain safe and functional workspaces, even in the harshest environments.

3. Transport & Logistics

We deliver no-fuss, quality doors that are easy to install and meet the specific needs of steel fabricators. Whether you’re building from scratch or retrofitting, Larnec can meet your security requirements with our Sentry™ 100 and 200 Series — and up-spec your hardware to help deter break-ins and theft.

Any of our solid core, dual-skin, metal-clad doors are a strong choice for fabrication environments, offering strength, reliability, and straightforward installation.

4. Agriculture & Farming

Rural sheds, workshops, and storage facilities face everything from searing heat to coastal moisture. That’s why we offer Sentry Protect™ — a powder coating finish engineered to resist corrosion in coastal areas, wet zones, and other harsh environments. The steel and weld points are treated in a two-stage chemical wash, primed, then powder coated in your choice of colour for long-term durability.

For regions with extreme weather, Larnec offers wind-rated doors up to Region D, capable of withstanding the most severe conditions in Australia.

Our 200 Series and 250 Series portable building doors are specifically designed and engineered for the strenuous demands of transportable and modular buildings. Fully metal clad and semi-solid, these doors are pre-hung in one of four frame options and fitted with perimeter seals to protect against violent dust storms and unfavourable weather. They come with a quality knob/lever exit set and three industrial-grade hinges, delivering durability and security in one package.

5. Health & Aged Care

In aged care, healthcare, and hospital environments, doors need to balance functionality, hygiene, safety, and privacy. Larnec offers fire-rated timber and metal-clad doors with varying core options to meet different performance requirements.

For facilities that require patient observation while maintaining privacy, Larnec can integrate premium privacy vision panels into any door. These built-in blind viewing ports allow staff to discreetly monitor patients or residents when needed, then provide privacy at the turn of a lever.

In hospitals, clinics, and residential care, these panels enable both care and dignity. In educational and commercial environments, they also enhance safety and privacy while keeping the blinds fully enclosed, tamper-proof, and easy to clean.

6. Manufacturing & Food Processing

Hygiene, ease of cleaning, and temperature control are critical in manufacturing and food processing. Larnec’s cool room doors are built for superior performance, using high-quality materials and finishes for durability and a professional appearance.

We offer core upgrades such as Polyisocyanurite (PIR), which provides enhanced thermal insulation and increased rigidity for more demanding applications. Our doors are designed for easy cleaning, low maintenance, and come in a variety of designs and COLORBOND® steel finishes to suit your operational needs.
