Identifying the unique security needs of your facility

Every facility, factory, shed, warehouse, or other commercial building requires protection against forced entry. The real challenge lies in deciding the degree of protection that is appropriate – and therefore which commercial door products are the right option.

Larnec is in the business of manufacturing superior personal access doors to promote better security for businesses and job sites around Australia. Get in touch with us now to learn more about our products, and order now for the fastest lead times in the business.

Why is a solid door important?

A door is often a building’s first line of defence and can significantly reduce the amount of damage to people and property during a break-in. When manufactured to correct standards, doors can provide a lockable, impermeable entry point that can be restricted to whoever has been granted access.

Below we will explore the different options of secure doors available to suit your needs as a business. If you have any questions about the below information, be sure to get in touch with the friendly customer service team at Larnec.

What are your security requirements?

The first step is to determine what level of protection is appropriate for the building’s use and location. Some buildings may not require much protection. These include garages, warehouses, and other locations with valuable goods that are more difficult to steal. It is unlikely that an attacker will force entry to steal a damaged car at a panel beater’s garage.

  • Retail and commercial building operators are usually more concerned with theft.
  • Government and high-end buildings tend to be more at risk for attacks that will result in wider damage.
  • The security needs of schools can range from burglary protection to improving the safety of students and staff.

Distinguishing between what you need in terms of security is important because different needs are addressed with different methods. Ensure compliance with Australian security standards by referring to the guidelines from Standards Australia.

It’s important to distinguish between the types of threats because they are addressed quite differently. Choosing a comprehensive door security solution is often the best way at mitigating any and all threats to people and property.

Finding the correct amount of security

Specifying a steel door rated with the highest levels of forced entry resistance would be appropriate for high level government facilities, or other facilities that contain sensitive material or personnel that need higher levels of protection.

But what about warehouses looking to protect retail stock? Or other retailers who are concerned with theft and burglary?

What is appropriate for corporate offices or retail locations whose owners are generally more concerned with theft? When it comes down to choosing features and applications of steel doors, there’s one simple thing to keep in mind: over-specification means unnecessary costs.

Design professionals and architects should consider the following:

  • The budget
  • The risk of physical attack and burglary
  • The severity of the risk

If you need a high level of security for any commercial or domestic door applications, the Larnec team can help you find the right solution.

Frequently asked questions

What are the most effective ways to reduce the risk of forced entry through a commercial door?

The most effective ways include using reinforced steel doors, heavy-duty locksets, and properly installed frames.
Doors designed to support high-security applications can be configured with anti-burglary hardware, tamper-resistant hinges, and multi-point locking. These features work together to reduce vulnerability at common forced entry points.

How does door construction impact resistance to forced entry?

Door construction directly impacts how well a door can withstand physical attacks such as prying, kicking, or forced leverage.
Dual skin steel doors are designed to provide greater strength and rigidity compared to single skin options. This makes them more suitable for external doors and high-risk industrial or commercial environments.

What type of locking system is best for preventing forced entry in commercial settings?

Heavy-duty commercial locksets or multi-point locking systems are typically the best options for preventing forced entry.
These systems distribute force across multiple نقاط, making it harder to breach the door. Similar configurations are commonly used in security door applications to support controlled access and asset protection.

Are door frames and installation as important as the door itself for security?

Yes, door frames and installation are just as important as the door itself when it comes to security.
Even a strong door can fail if the frame or fixings are weak or incorrectly installed. Pre-hung door systems are designed to support proper alignment and structural integrity, reducing installation-related vulnerabilities.

When should I consider upgrading to a high-security or specialised door solution?

You should consider upgrading when the site involves high-value assets, remote locations, or increased security risks.
In these cases, doors can be configured with reinforced components and advanced locking systems to support higher levels of protection. These solutions are suitable for warehouses, construction sites, and storage facilities where forced entry risk is elevated.
