How to Choose the Right Security Door for Your Business

Updated: October 2025

Choosing the right security door is one of the most important steps in protecting your business. A high-quality door acts as a strong physical barrier and provides peace of mind by enhancing the overall safety of your premises.

At Excel, we understand that every business has different needs. That is why we offer a wide range of industrial security doors built to provide strength, safety and durability. Whether you are looking to secure staff access points, maintain internal temperatures or meet fire safety regulations, we have a solution to match.

In this guide, we explain what to consider when choosing a security door and how Excel can support you at every stage of the process.

What to Consider When Choosing a Security Door

1. Know Your Security Requirements

Start by thoroughly assessing the risks specific to your business site. Identify vulnerable entry points such as doors, windows, loading bays or service entrances that may be targeted by intruders or exposed to environmental hazards. Consider the types of threats you want to guard against. Are you primarily concerned about break-ins, vandalism, fire hazards or unauthorised access by staff or visitors?

Think about the value of the assets inside, the crime rate in your area and any past security incidents. Also factor in environmental challenges like exposure to harsh weather, dust, moisture or pest intrusion that could affect door performance and longevity.

By gaining a clear and comprehensive understanding of these risks and operational needs, you can prioritise the features you need in a security door. This ensures you select a solution that not only strengthens your physical security but also supports the day to day running of your business efficiently and compliantly.

2. Understand the Level of Protection You Need

Security doors are available in different grades depending on the level of resistance required. Excel offers options from unrated through to LPS 1175 Security Rating Level S3, so you can choose the right level of security for your premises.

• Unrated: Suitable for low-risk areas where the focus is on access control, privacy or environmental separation rather than physical attack resistance.
• LPS 1175 Security Rating Level S1: Offers basic resistance against opportunistic attacks using simple hand tools over a short period.
• LPS 1175 Security Rating Level S2: Provides greater protection, resisting more aggressive attempts using a wider range of tools for a longer duration.
• LPS 1175 Security Rating Level S3: Designed to withstand experienced attackers using tools such as crowbars, drills and bolt cutters, maintaining resistance for up to 5 minutes of sustained attack. Ideal for high-risk or high-value sites.

Selecting the right rating ensures your door offers an appropriate level of protection based on the specific risks at your site.
