Choosing the right commercial exterior doors is one of the most important decisions when designing, constructing, or renovating a commercial building. The right door impacts security, durability, energy efficiency, code compliance, and curb appeal. At CDF Distributors, we work with contractors, facility managers, business owners, and property developers every day to help them select the best door solution for their specific needs. Whether you're looking for commercial metal exterior doors, commercial exterior glass doors, or guidance on where commercial exterior wood doors fit into a project, our team has the expertise to help you make the right choice.
In this guide, we'll compare three of the most common types of exterior commercial doors: hollow metal doors, metal building doors, and storefront doors. We'll cover their similarities, differences, ideal applications, and which option is best for your project.
What Doors Are Compatible with Exterior Applications?
Several door types can be used successfully in exterior commercial applications, but not all are built for the same environments.
The most common and effective options include:
Among these options, hollow metal, metal building, and storefront doors are among the most popular because they combine durability, security, and long-term value. Each serves a different purpose and offers unique advantages depending on the building type and desired appearance.
Hollow Metal Doors
When it comes to versatility and performance, hollow metal doors are one of the most widely used commercial metal exterior doors available today.
These doors are an excellent choice for virtually any exterior application. Hollow metal doors are available in multiple fire ratings, including:
- 20-minute
- 45-minute
- 60-minute
- 90-minute
- 3-hour (available only with masonry wall)
CDF Distributors' hollow metal doors can be configured with pre-installed lite kits and louvers, making them adaptable for a wide variety of building requirements. They are factory primed and ready to paint, allowing contractors and building owners to easily match the building's design.
Constructed from durable 18-gauge galvannealed steel, hollow metal doors provide superior strength and resistance to damage compared to many alternative door materials. When paired with a 16-gauge steel frame, they create a highly secure entrance solution for commercial properties.
To further improve performance, these doors can be configured with hardware options such as mortise locksets and accessories, including weatherization kits. These additions help improve security, insulation, and protection from the elements.

Best Applications for Hollow Metal Doors
Hollow metal doors are ideal for:
- Schools and universities
- Hospitals and healthcare facilities
- Manufacturing facilities
- Government buildings
- Warehouses
- Service Entrances
- Multi-tenant commercial buildings
- Any location requiring fire rated openings
For projects prioritizing durability, security, and code compliance, hollow metal doors are often the preferred solution.
Metal Building Doors
Metal building doors are specifically designed for installation in pre-engineered metal building systems. They offer many of the same benefits as hollow metal doors while simplifying installation.
CDF Distributors' metal building doors come pre-assembled and pre-hung for easy installation on metal buildings. The door leaf is constructed with strong 18-gauge galvannealed steel and can be configured with various lite kit options to provide visibility and natural light.
Unlike standard hollow metal doors that are primed and ready for paint, metal building doors are powder coated and available in:
- White
- Black
- Bronze
They are offered in both single-door and double-door configurations, making them suitable for a wide range of building layouts and access requirements.

Best Applications for Metal Building Doors
Metal building doors are best suited for:
- Pre-engineered metal buildings
Because they are delivered pre-hung and pre-assembled, metal building doors can significantly reduce installation time and labor costs.
Storefront Doors
For projects where appearance, visibility, and customer experience matter, storefront doors are often the preferred choice.
Storefront systems are available in clear or dark bronze anodized aluminum. Both the door and frame are constructed from aluminum, creating a strong, attractive entrance system that resists corrosion while maintaining a clean, professional appearance.
CDF Distributors' storefront doors come with the glass and hardware pre-installed, streamlining installation and reducing time spent on site.
As one of the most popular forms of commercial exterior glass doors, storefront doors are designed to maximize visibility and allow natural light into a building. This makes them especially effective for customer-facing businesses.
Storefront systems can also be customized with:
- Sidelites
- Transoms
- Additional glazing options
These features create a more open and inviting entryway while helping businesses establish a distinctive architectural appearance.
For many renovations, storefront doors can serve as an attractive upgrade from traditional hollow metal openings, instantly improving aesthetics while maintaining strength and functionality.
What Doors Shouldn't Be Used for Exterior Applications?
While many customers ask about commercial exterior wood doors, the reality is that most commercial wood doors are not suitable for long-term exterior exposure.
Our wood doors should not be used for exterior applications because they are susceptible to moisture and temperature fluctuations. Over time, exposure to changing humidity, rain, sunlight, and temperature extremes can negatively impact their appearance and performance.
However, wood doors remain an excellent option for interior applications. CDF Distributors offers a variety of stained veneer doors as well as MDF primed wood doors designed specifically for interior commercial use.
Replacing Doors
One of the most common challenges during door replacement projects is dealing with non-standard openings.
In many cases, contractors can use standard door sizes in non-standard openings through the use of frame modifications, filler panels, or custom configurations. Working with an experienced supplier helps ensure the replacement door meets both code requirements and project specifications without unnecessary delays.
The CDF Distributors team can help identify the best replacement solution and determine whether a standard opening product or custom configuration is the most cost-effective option.
