These doors offer a range of benefits that provide your business with unparalleled protection and add value and curb appeal. In this blog post, we will explore the 5 reasons to buy a steel security door for both residential and commercial properties.

From enhanced security features and durability to energy efficiency and aesthetic appeal, steel security doors offer a multitude of advantages that make them a top choice for homeowners and businesses alike. This comprehensive blog post delves into the world of steel security doors, the benefits of steel doors, and why they are worth every penny.

1. Enhanced Security Features

Primarily designed for commercial or industrial premises, steel security doors offer exceptional protection against potential forced entries. They boast advanced locking systems, reinforced frames, and force-resistant impact, affording businesses and homeowners a sense of security and peace of mind superior to what traditional doors can offer.

Steel doors, typically constructed from solid metal like aluminium or steel, exhibit greater robustness and security than their wooden or fibreglass counterparts. Their design - featuring advanced locking systems, reinforced frames, and resistance to impact - not only boosts your property’s security but also provides a fire-resistant barrier, enhancing overall safety.

Locking System

One of the key features of these industrial metal doors is their high-quality deadbolts and other locking mechanisms, which ensure a higher level of security.

A variety of locking systems can be incorporated into steel security doors, including:

  • Europrofile lock cylinders
  • Multi-point locking systems
  • Electric locks
  • Lever locks

Reinforced Frames

Reinforced frames add extra strength to steel security doors, making it difficult for intruders to force their way in. Materials such as galvanised steel are employed to reinforce steel security door frames.

Steel security door frames can be reinforced using several methods. These include:

  • Installation of a steel kick plate at the door’s bottom
  • Use of safety studs, corrugated pins, or setscrews for securing hinges
  • Reinforcement of the strike plate and/or door frame to deter forced entry
  • Utilisation of steel L-angle or door reinforcement plates to augment strength
  • Addition of security hinges to enhance security.

This reinforcement significantly contributes to the prevention of forced entry, increasing the strength and durability of the door and providing superior security and protection.

Force-Resistant Impact

With their force-resistant impact, steel security doors pose a formidable obstacle to break-in attempts. Constructed from reinforced steel, these doors offer robustness and longevity, maintaining their resilience even under excessive force. Their drill-proof design further complicates unauthorised access.

To measure the force-resistant impact of a steel security door, standards such as PAS 24 are used. This involves assessing the door’s resistance to impacts from both soft and hard bodies, such as a 30 kg bag to simulate an impact. Dynamic impact tests can also be performed to simulate an intruder attempting to kick their way through the door, helping to evaluate the door’s ability to withstand forced entry and enhance overall security.

2. Durability and Longevity

Key advantages of steel security doors include:

  • Durability
  • Longevity
  • Weather resistance
  • Tolerance for high traffic
  • Long-term investment value

Depending on factors like usage and location, these doors can last anywhere up to 80 years. To ensure longevity, regular maintenance, including cleaning and lubrication of hinges and locks, is advisable.

Business owners will find steel security doors to be an excellent long-term investment due to their durability and reliable security, bringing assurance of their premises’ safety.

Weather Resistance

With their ability to endure extreme weather conditions, steel security doors remain functional and secure over the years. Their features include:

  • Steel construction
  • Protective finishes like powder coating or galvanised
  • Exceptional resistance to water, allowing them to withstand heavy rainfall without performance or integrity compromise.

In addition to their resistance to water, steel security doors also possess a remarkable resistance to extreme heat and are not affected by warping or moisture. Furthermore, they are designed to withstand high temperatures and provide a fire barrier, making them an ideal choice for both residential and commercial properties.

High Traffic Tolerance

The high traffic tolerance of steel security doors enables them to withstand frequent use without sacrificing structural integrity. Made from heavy-duty materials, these doors are designed to resist break-ins and withstand wear and tear. Stainless steel, known for its strength, durability, and resistance to corrosion, is an optimal choice for high traffic doors.

To ensure high traffic tolerance, regular inspection and maintenance are highly recommended. This includes periodic assessments, routine tasks, and adherence to manufacturers’ service specifications and legislation compliance. Additionally, it is advised to consider ongoing maintenance and repairs for doors that experience high traffic usage.

Long-Term Investment

Investment in a steel security door is a long-term proposition, as these doors are durable and consistently secure. On average, they are estimated to last between 30 and 80+ years, making them a worthwhile investment. To ensure their longevity and effectiveness, regular maintenance is crucial. This includes:

  • Cleaning the door regularly
  • Lubricating hinges and locks
  • Inspecting the door for any damage or wear
  • Touching up paint as needed
  • Replacing weatherstripping when necessary
  • Adhering to a maintenance schedule

By following these maintenance practices, you can ensure that your steel security door remains in optimal condition for many years to come.

A steel security door can provide homeowners and businesses with enhanced security and peace of mind, potentially increasing the value of the property and lowering insurance costs. Security features can increase the value of a home. Buyers are usually willing to pay extra for such added protection.

3. Energy Efficiency Advantages

Energy efficiency is another significant advantage of steel security doors. They offer excellent insulating properties and a tight seal, which can help reduce energy bills and improve overall home comfort. Steel security doors are typically insulated with mineral wool, which helps to impede thermal transmission and bolster insulation. Furthermore, the two-piece construction and seals of steel doors provide weatherproofing and draught-proofing, thus augmenting their insulation properties.

The insulation in steel security doors contributes to energy efficiency by preventing heat loss and reducing air leakage. This helps to minimise the requirement for central heating and also cuts energy waste through conduction. Insulated steel doors are equipped with an insulating core and high-quality weather seals, making them energy-efficient.

Insulating Properties

The insulating properties of steel security doors include:

  • Foam core that helps maintain indoor temperatures and reduce energy consumption
  • Insulated core, such as mineral wool, helps to maintain temperature and minimise heat loss
  • Two-piece construction and high tensile steel material that offers additional insulation advantages

The strong insulation and air tightness of steel security doors help to keep the internal temperature comfortable during both cold and hot weather, thus reducing the need for excessive heating or cooling and resulting in energy savings. Moreover, insulated steel doors can also help to keep out draughts and minimise air leakage, further improving energy efficiency.

Tight Sealing

Steel security doors are designed to seal tightly, preventing air leaks and further improving energy efficiency. They are made airtight through the use of weatherstripping and proper installation techniques, eliminating gaps and leakage.

Steel security doors incorporate a variety of materials to ensure a secure connection, including:

  • Rubber seals
  • V-seals
  • Galvanised steel
  • Polyurethane insulation
  • Laminated glass panels

The steel construction of the door also enhances its strength and durability, further contributing to its tight sealing properties.

5. Boosting Value

Steel security doors offer several benefits for homeowners, including:

  • Increased security
  • Peace of mind
  • Enhanced curb appeal
  • Potential reductions in insurance premiums
  • Increased resale value

By combining strength, durability, and appealing design, these doors can significantly boost a property’s aesthetic value.
