When it comes to commercial buildings, doors and frames are more than just entry points—they are essential for security, fire safety, energy efficiency, and accessibility. In this guide, we’ll cover the basics of commercial steel and wood doors, as well as hollow metal frames. We’ll also touch on common hardware like access control devices, closers, thresholds, and sweeps to help you make informed choices for your facility.
Types of Commercial Doors
Steel Doors
Steel doors are a top choice for commercial applications due to their durability, fire resistance, and security benefits. They are typically constructed with a steel face and a core material such as honeycomb, steel stiffened, polystyrene, or polyurethane for insulation and impact resistance. These doors are commonly used in offices, warehouses, hospitals, and schools. Additionally, glass vision lites can be added to steel doors to allow visibility while maintaining security and fire-rating requirements.
- Highly durable and long-lasting
- Fire-rated options available
- Strong security against forced entry
- Low maintenance compared to wood doors
- Can be fitted with glass vision lites for added visibility
Wood Doors
Wood doors are popular for their aesthetic appeal and versatility. They are available in various finishes, including veneers and laminate, making them ideal for office spaces, hospitality settings, and high-end commercial applications. Like steel doors, wood doors can also include glass vision lites, providing visibility while maintaining a professional look.
- Offers a warm and professional look
- Available in various styles and finishes
- Can be fire-rated for safety
- Good sound insulation properties
- Can incorporate glass vision lites for aesthetic and functional purposes
Hollow Metal Frames
Hollow metal frames are commonly used in commercial settings due to their strength and adaptability. They are made from steel and can be customized for different wall conditions, including drywall, masonry, and concrete installations. These frames support heavy-duty doors and offer enhanced security and fire resistance.
- Strong and resistant to impact
- Can accommodate fire-rated doors
- Works well with access control and security hardware
- Long lifespan with minimal maintenance
Essential Door Hardware
Access Control Devices
Access control devices such as keycard readers, biometric scanners, and electronic locks help manage building security by restricting entry to authorized personnel only.
Door Closers
Door closers ensure that doors close automatically after use, preventing air leaks and enhancing security. They are required in fire-rated doors to keep them closed in case of an emergency.
Thresholds & Sweeps
Thresholds and door sweeps help seal the gap between the door and the floor, improving energy efficiency and preventing drafts, moisture, and pests from entering the building.
Opening Mechanisms
- Panic Devices – Also known as crash bars or exit devices, these allow quick egress in emergency situations.
- Push Bars – Similar to panic devices but used in non-emergency settings.
- Lever Handles – A standard option for commercial spaces that provides ease of use.
- Knob Handles – Less common in commercial settings due to accessibility concerns.
- Automatic Operators – Ideal for ADA compliance, allowing hands-free access with motion sensors or push buttons.
- Magnetic Locks (Maglocks) – Used in conjunction with access control systems for secure entry.
Choosing the Right Commercial Door and Frame
When selecting commercial doors and frames, consider factors such as security requirements, fire ratings, environmental conditions, and aesthetic preferences. Steel doors with hollow metal frames are ideal for high-security and high-traffic areas, while wood doors work well in office environments where design matters.
For optimal performance, ensure that your doors are paired with the appropriate hardware and installed correctly. Consulting with a commercial door specialist can help you make the best choice for your needs.
