Steel doors

External steel doors are great if you wish to add another entrance to your house. Unlike your main front door and windows, which should tie in with the overall aesthetic of your house, back doors made of steel are mostly functional and help keep your home safe from intruders. If you want to add external or internal garage doors to get in and out of your garage quickly, use our configurator to create the ideal steel door.

Steel look, sturdiness, and reliability: steel back and front doors

Steel doors are great for a variety of different reasons. Due to the sturdy material of the panel, these doors protect your house from burglars, even if they manage to enter your garage. As steel is also fire-resistant, it is also used for fire exit doors. If you want your steel door to tie in with your property's design, add glass or create an industrial-style panel that fits your taste and specifications.

Excellent thermal insulation: Cleverly constructed door frames and leaves

Steel doors are the standard choice for fire exits or security garage doors. They are not only hard to manipulate but also help to keep your building energy efficient. This is especially important if you wish to add a back door with a window in a heated room.

Similar to an aluminium door, steel door sets are not efficient in keeping your house warm. This is why we manufacture our steel doors with a timber core that functions as a thermal barrier and adds insulation to your steel doorway.

We only use double or triple glazing for our steel doors to ensure high-quality insulation.

This increases the U-value of your external metal door, making it a great choice if you want to keep your energy costs down.

Keep your home safe from fire with our steel doorsets

Unlike some other materials, steel is virtually impossible to manipulate and resistant to fire. That´s why it´s the ideal material for security doors. The steel acts as a fire barrier compared to other timber-made internal doors. Therefore, steel security entrance doors are also the best choice for fire exits.

Burglars will have difficulty manipulating or passing an internal or external door made of steel and usually decide against trying to break in. At windows24.com, we also use triple glazing to ensure the highest security for internal and external steel security doors. This allows you to add glazed elements to your door that function as a window.

All our steel doors are hinged with security furnishings such as multi-point locking systems or security pins. This means that the door lock, which is often the weakest point of any back or front door, cannot be forced open with standard tools.

Create your bespoke steel entrance doors

Choosing the perfect design for steel entrance doors can be daunting. Whether you desire a plain industrial steel door with a timeless solid panel or opt for glazed elements to spice up your external steel door with glazing: our configurator can easily guide you through our range of security doors. Glass elements on your hinged door also function as a window and let sunlight into your home. To keep the glass window from becoming a security breach in your steel security door, we use double or triple glazing that further increases the thermal insulation of your door leaf, too.

Our steel doorsets come in an extensive range of designs and colours. This allows you to create an on-trend external or internal entrance that perfectly suits your building's aesthetic. These entrance doors are powder coated, making them very resistant to rain or sun exposure. If standard white and grey do not meet your taste, our range of wooden decors may be a nice alternative. This allows you to benefit from the advantageous properties of industrial steel doors while adding the warm and inviting finish of wooden doors.

Depending on the chosen model, you have a great selection of different points to decide on, including:

  • Swing direction
  • Handles
  • Door stop
  • Glass
  • Security measures

Deciding whether the security entrance should be hinged on the left or the right-hand side depends on your unique situation. Whether you choose an inward opening or an outward opening – keep the surrounding area in mind. If you have a large door opening, side panels can add to the steel look. But with too little space, you want to maximise your steel doorsets’ functionality. If you're going to enlarge your home´s living space, you may want to look into our outswing design option – or think about bi-folding French doors. The side on which your door leaf is hinged is up to you.

We offer a variety of different front door handles for our security doors. While some doors only come with regular stainless steel door handles, you can also select stainless steel door knobs for most of our models. Door knobs require a key for opening the steel lock, making it a safe option for the outside panel – perfect for garage doors in need of a locking system.

Frequently Asked Questions

Steel doors are convincingly durable and secure. Due to their material and weight, they are virtually maintenance-free and impossible to manipulate, making them a very unpopular choice for burglars to break into. Due to the standard steel finish these doors are also resistant to fire. This makes them an excellent choice for hinged back entrances, or inside a garage, where burglars can easily break into an entrance unnoticed.

The price of external or internal doors depends on various factors. The chosen model and desired furnishings are usually the main factors for a higher price point. Unlike more favourable uPVC entrances, our full-range steel doors are the most durable and safest option for a door. Increased security measures and strong materials result in a higher price. Non-standard sizes and added glass windows also play into the costs of security doors.

We are sure that you’ll find your perfect door in our variety of doorsets at windows24.com. From solid panels to ornamental glass inserts, our configurator can help you choose a door or window that looks great and offers you great value for your money.

To ensure that your new door ties in with the style of your front door and windows, we have a few colour options for our steel security doors. Our classic white or modern grey doors may suit you best if you prefer a timeless look. If you want to add a unique touch to your back door, you might want to look into our wooden decors. Our elegant 'Walnut' decor is darker than our slightly reddish and warm 'Golden Oak' decor and works well with glazed elements. As our steel doors have the same colour on the inside as they do on the outside, you may want to keep your style, glass elements, and other interior doors in mind when selecting a colour or decor.
