Steel external doors are a popular choice for residential, commercial, and industrial buildings due to their durability, security, and resistance to harsh weather conditions. They come in various designs to suit different needs, whether it's for standard entryways, high-security areas, fire safety compliance, or specialized uses like container conversions and toilet blocks.
In this blog, we will explore the different types of external steel doors that are available and their specific features.
Standard Steel Door
A
standard steel door is a versatile option used in residential and commercial buildings. These doors are typically made from galvanized or stainless steel and are designed to withstand everyday wear and tear. They provide a high level of security while being cost-effective and low-maintenance.
Standard steel doors often come in different thicknesses and can be fitted with various locks and finishes to match aesthetic preferences. They are commonly used for back entrances, garages, and general-purpose access points. Some models also offer insulation properties to improve energy efficiency and soundproofing, making them suitable for indoor applications where noise reduction is important.
High-Security Steel Door
High-security steel doors are designed for areas that require enhanced protection against forced entry and vandalism. These doors are made from heavy-gauge steel with reinforced cores and multiple locking points.
They often feature:
- Anti-drill and anti-pick locks
- Reinforced frames
- Bulletproof or impact-resistant panels
- Multi-point locking systems
- Hidden hinges to prevent tampering
High-security steel doors are ideal for banks, warehouses, government buildings, and other high-risk properties where security is a top priority. Some models are also equipped with electronic access control systems, including keycard or biometric entry, making them even more secure for sensitive locations.
Fire Exit Steel Door
Fire exit steel doors, also known as emergency exit doors, are crucial for safety compliance in commercial and industrial buildings. These doors provide a secure yet accessible exit route during emergencies like fires.
Key features include:
- Panic bars for quick egress
- Self-closing mechanisms
- Fire-resistant coatings
- Weather-sealed construction
- Luminous or glow-in-the-dark signage for visibility in smoke-filled areas
Fire exit steel doors help ensure compliance with fire safety regulations and are commonly installed in offices, schools, hospitals, and public buildings. Some fire exit doors also feature alarm systems that sound when opened, ensuring they are used only in emergencies.
Double Steel Door
Double steel doors are designed for wider openings and provide increased accessibility for large equipment, vehicles, or heavy foot traffic. These doors are commonly used in industrial settings, warehouses, and commercial buildings.
They are available in various configurations, including:
- Full double doors (both doors open)
- Active and inactive leaf configurations (one door fixed, one operable)
- Fire-resistant coatings
- Custom widths and heights
- Optional reinforced glass panels for visibility and light
Double steel doors can also be customized with insulation for better thermal efficiency, as well as high-security locks to prevent unauthorized access. They are particularly useful in areas that require frequent movement of goods and machinery.
Combination Lock Steel Door
Combination lock steel doors offer keyless entry and enhanced security through mechanical or electronic keypad locks. These doors eliminate the need for traditional keys and allow for controlled access.
Benefits of combination lock steel doors include:
- No risk of lost or stolen keys
- Multiple user codes for different personnel
- Optional biometric or smart card access
- Enhanced security for restricted areas/li>
- Ability to integrate with building access control systems
These doors are commonly used in office buildings, server rooms, and high-security zones where keyless entry is preferred. Many models also feature backup power options to ensure functionality during power outages.
Shipping Container Steel Door
Shipping container steel doors are designed for modified shipping containers used as storage units, offices, workshops, or temporary buildings. These doors are specifically built to fit into the rigid steel structure of shipping containers while providing secure and weatherproof access.
Features include:
- Heavy-duty steel construction
- Weather seals for protection against moisture and dust
- Locking mechanisms suited for container security
- Custom sizing to fit different container modifications
- Reinforced hinges to withstand frequent use
These doors are popular in construction sites, temporary housing, and mobile business setups. Some models also include ventilation grilles or windows for better airflow and visibility inside the container.
WC Toilet Block Steel Door
Steel doors for WC toilet blocks are essential in public restrooms, construction sites, and outdoor facilities. They are designed to withstand frequent use, exposure to moisture, and potential vandalism.
Common characteristics include:
- Corrosion-resistant coatings to withstand humidity and chemicals
- Ventilation options for airflow and odor control
- Lockable options for privacy, including indicator bolts or key locks
- Easy-to-clean surfaces for hygiene and maintenance
- Customizable sizes to fit modular restroom setups
WC toilet block steel doors are commonly found in schools, parks, event venues, and industrial sites. Some models are also equipped with soundproofing to provide better privacy for users.
Fire-Rated Steel Door
Fire-rated steel doors provide additional protection against fire and smoke, helping to contain the spread of flames within a building. These doors are tested and certified to withstand fire for a specific period, such as 30, 60, 90, or 120 minutes.
Key features include:
- Fire-resistant core materials such as mineral core or steel-reinforced honeycomb
- Intumescent seals that expand during a fire to block smoke and flames
- Self-closing mechanisms for automatic sealing in case of fire
- Compliance with fire safety standards such as BS EN 1634-1 or UL 10C
Fire-rated steel doors are often required in stairwells, corridors, and critical escape routes in commercial and high-rise buildings. Some models also feature reinforced glass panels that maintain fire resistance while allowing visibility.
PAS24 Steel Door
PAS24 steel doors are certified to meet the security standards set by PAS 24:2016, which outlines enhanced security performance for door sets. These doors undergo rigorous testing against forced entry methods, including drilling, cutting, and prying.
Benefits of PAS24 steel doors include:
- High resistance to burglary attempts
- Multi-point locking systems
- Reinforced hinges and frames
- Compliance with building security regulations
- Tested for resistance against impact, manipulation, and lock-picking
These doors are commonly used in residential and commercial properties where higher security standards are required. Some models also integrate smart locking mechanisms for remote access control.
Conclusion
Steel external doors come in various types to meet different security, safety, and functional requirements. Whether you need a standard steel door for general use, a high-security door for added protection, or a fire-rated door for safety compliance, there is a steel door to suit every need.
Choosing the right steel door depends on factors like security level, fire resistance, access control, and environmental exposure. Investing in the appropriate steel door can enhance the safety, security, and durability of any building or facility.
