Door closers ensure that the door closes automatically after it has been opened, preventing drafts and ensuring security.

C. Glazing Options

For glass doors or doors with window inserts, the glazing options play an important role. Different types of glass can be used, such as clear glass for maximum visibility, frosted glass for privacy, or tinted glass for solar control. Insulated glass units can be installed to improve energy efficiency by reducing heat transfer.

D. Decorative Elements

Commercial entry doors can be enhanced with decorative elements such as embossed patterns, carved details, or custom signage. These elements add a unique touch to the door and help to create a distinctive brand identity for the business.

IV. Security Considerations for Commercial Entry Doors

A. Locking Mechanisms

A robust locking system is essential for the security of commercial entry doors. Deadbolts are a common choice as they provide a strong physical barrier. Mortise locks offer additional security features and can be integrated with access control systems. Electronic locks, such as keypad locks or card - reader locks, provide convenient and secure access control.

Multi - point locking systems are often used for swinging doors. These systems engage several locking points along the door edge, making it more difficult for intruders to force the door open.

B. Reinforcement

Commercial entry doors can be reinforced to enhance their resistance to forced entry. This can include the installation of steel plates or bars on the door surface or within the door core. Reinforced frames and hinges also contribute to the overall security of the door.

C. Access Control Systems

Access control systems are becoming increasingly common in commercial buildings. These systems can include key cards, biometric scanners, or proximity readers. They allow for precise control over who has access to the building and at what times. Access control systems can be integrated with security cameras and alarm systems for a comprehensive security solution.

D. Impact Resistance

In areas where there is a risk of impact, such as loading docks or industrial facilities, commercial entry doors should have high impact resistance. This can be achieved through the use of heavy - duty materials and reinforced construction.
