    Simple Door

    A simple door is a common architectural element present in many residential, commercial, and industrial buildings. Generally rectangular, it is designed to allow access from one room to another while providing physical separation when necessary.

    Materials: Simple doors can be made from various materials, such as wood, metal, PVC, or a combination of these materials depending on their intended use and the architectural style of the building.

    Structure: A typical simple door consists of several elements, including a frame surrounding the door, hinges allowing its movement, a handle or knob to facilitate opening, and possibly a latch or lock to ensure security.

    Finish: The door’s surface can be finished in different ways depending on aesthetic preferences. Wooden doors can be painted, stained, or left natural to showcase the beauty of the wood grain. Metal doors can be coated with paint to enhance their appearance and protect against corrosion.

    Types: There are different types of simple doors, including swing doors that open inward or outward, sliding doors that move laterally along a track, and folding doors that fold in on themselves to save space.

    Size: The dimensions of a simple door vary depending on its location and use. Main entrance doors are generally larger than interior doors, and the height may vary according to local building standards.

    Additional Features: Some simple doors are equipped with windows, decorative panels, or other architectural elements to add character to the ensemble. Additionally, modern devices such as automatic door closers or electronic locks can be integrated to improve functionality and security.

    Security Door

    Structure and Materials: A security door is designed to offer enhanced protection against intrusions and break-in attempts. The basic structure typically includes a reinforced steel core, offering additional resistance. The exterior panels can also be made of steel, sometimes covered with materials such as wood or PVC for a more pleasing aesthetic.

    Locking System: Security doors are equipped with advanced locking systems to enhance security. This may include multi-point locks, deadbolts, electronic locking systems, drill-resistant locks, and other advanced security devices.

    Armoring: The term “armoring” refers to the door’s ability to resist various attacks. Armored doors can be equipped with steel plates, composite materials, or other protective layers that make them resistant to break-in attempts, drilling, or cutting.

    Security Glazing: Some armored doors are also equipped with security glazing, designed to resist glass-breaking attempts. These glazings can be bulletproof, anti-burglary, or simply reinforced to discourage intrusions.

    Anti-Pry Panels: Some models of armored doors are equipped with anti-pry panels. These devices are designed to prevent the use of tools such as pliers to force the door open.

    Finish: Although the main function of an armored door is security, manufacturers often offer a variety of finishes and styles to suit the aesthetics of different environments. This can include wood, metal, or other decorative material finishes.

    Security Certifications: Armored doors can be certified according to specific security standards. Certifications can come from independent bodies that evaluate the door’s resistance to physical attacks, break-in attempts, or even bullets, depending on the required level of protection.
