Premium High-Security Steel Auxiliary Entrance Doors | Customizable Collection

This collection showcases a versatile range of high-quality, made-to-measure steel auxiliary entrance doors. These doors are the optimal solution for various access points, including garages, basements (cellars), garden entrances, and courtyards. They are designed to offer both high security and excellent functionality while maintaining appealing design options.

Steel is an extremely robust material, providing superior protection against forced entry compared to wood, aluminum, or plastic. Its high density, exceeding 7 grams per cubic centimeter {7 g/cm} / over 0.25 pounds per cubic inch), ensures the door is highly resistant to deformation and damage from impact.

Key Security Features:

Every steel door in this collection comes equipped with advanced security hardware to protect your property. This includes a robust 3-bolt locking system inspired by safe technology, turning the lock into a significant obstacle for intruders. Additionally, the doors feature back-hinge bolts that provide an even more secure anchoring of the door in the frame.

Thermal Insulation and Construction:

For doors leading into heated living spaces, excellent thermal insulation is a priority. While steel is a natural heat conductor, the doors are engineered with a special energy-efficient wooden core construction to compensate, ensuring strong U-values (thermal transmittance) and helping to keep heating costs low. Models that include glass elements are fitted with high-quality thermal protection glass, which is often triple-glazed and specially treated for optimal energy efficiency. For non-heated areas like garages or cellars, the insulation requirements are less critical, highlighting the door's versatility.

Customization Options:

You can individualize your door to meet your specific needs and aesthetic preferences.

• Design Models: Choose from a wide portfolio of pre-configured designs, ranging from simple, plain concepts to more refined variants with extensive glazing and decorative elements. Available models include Dinslaken, Fulda, Celle, Aschaffenburg, Kempten, Aalen, Lippstadt, and Plauen.

• Color Finish: Available colors, such as classic White and Anthracite (Dark Gray), are applied using a durable powder coating process.

• Hardware and Handles: All models except Dinslaken allow you to choose between a knob-handle on the exterior with an interior stainless steel handle, or a configuration with stainless steel handles on both sides. The Dinslaken model is only available with standard handles.

• Opening and Hinge Direction (Door Swing): You must specify the door's opening direction (inward or outward) and the hinge side (known as DIN Right or DIN Left) based on the structural situation to ensure optimal use of limited space.

• Threshold: Each door is equipped with a durable aluminum threshold.
