Commercial Doors

Choosing the right commercial exterior doors is an important part of any construction project. The wrong door can lead to maintenance issues, performance problems, and costly replacements down the road. The right door can improve security, handle daily traffic, and stand up to years of weather exposure.

When comparing commercial metal exterior doors, commercial exterior glass doors, and commercial exterior wood doors, many contractors focus on appearance first. While appearance matters, it's only one piece of the decision.

The location of the opening, the amount of traffic it receives, and the level of exposure to weather often have a bigger impact on long-term performance than the material itself.

In this guide, we'll compare the most common types of exterior commercial doors and explain how to choose the best option for your project.

What Makes a Door an Exterior Door?

Most people think of exterior commercial doors as the main entrance to a building. In reality, an exterior opening

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.

Primed hardboard wood doors are designed to make finishing easier while giving contractors and facility managers the flexibility to match virtually any interior color scheme. Supplied with a factory-applied white water-based latex primer, these paint grade commercial doors arrive ready for field painting, helping reduce preparation time while providing a consistent surface for a professional finish. 

Whether you're installing commercial flush wood doors in an office, school, healthcare facility, multifamily property, or another commercial building, proper preparation and painting are essential for achieving the best appearance and long-term performance.

This guide explains how to prepare, paint, and finish MDF commercial wood doors using the methods recommended by CDF Distributors.

Primed hardboard wood doors are one of the most widely specified options in commercial construction, but the terminology often gets mixed up. You'll hear them called MDF commercial wood doors, paint grade commercial doors, or commercial flush wood doors depending on the project. In many commercial specifications and supplier catalogs, these terms are used interchangeably to describe paint-grade flush wood doors with smooth engineered surfaces.

At their core, they all serve the same purpose: a reliable, paint-ready door solution built for interior commercial environments where consistency, cost control, and finish flexibility matter.

CDF Distributors supplies primed hardboard doors engineered for real jobsite conditions, not just showroom specs. That difference shows up in how they perform across schools, offices, healthcare facilities, and multifamily projects.

Industrial doors are designed to meet the demands of high-traffic, high-impact environments such as warehouses, manufacturing facilities, distribution centers, and metal buildings. Unlike standard doors, industrial doors are built for durability, security, and performance, often incorporating reinforced materials like steel, specialized hardware, and compliance with strict safety and fire requirements.

Whether you're looking for industrial steel doors, industrial glass doors, or durable exterior steel doors, the right solution needs to balance strength, function, and long-term reliability. That's where choosing the right industrial door supplier makes all the difference.

Industrial vs. Commercial Doors: What's the Difference?

While industrial and commercial doors are often used interchangeably, there are key differences in performance expectations and application.

Similarities

• Both must meet building codes and fire ratings (read about how doors are fire rated here)
• Both are typically built

Many people assume that commercial doors and industrial doors are completely different products. In reality, the difference is often based on where the door is installed rather than the door itself.

A steel door used in an office building may be very similar—or even identical—to a steel door used in a warehouse, manufacturing facility, or distribution center. What matters most are the performance requirements of the opening, including security, fire ratings, traffic levels, and environmental conditions.

Understanding how commercial and industrial applications differ can help architects, contractors, facility managers, and building owners select the right door system for their project.

In this guide, we'll explain how commercial and industrial doors are commonly defined, where they're used, and what factors matter most when choosing a door.

Commercial storefront doors are one of the most important features of a building's entrance. Whether you're designing a retail storefront, office building, restaurant, school, or healthcare facility, the right storefront door can improve visibility, security, and curb appeal while creating a welcoming experience for visitors.

Many modern commercial glass door systems incorporate sidelites and transoms to maximize natural light and create a more open, professional appearance. These fixed glass panels expand the visible glass area around a storefront door, helping businesses showcase their interiors while enhancing the overall design of the entrance.

From single storefront doors to complete commercial storefront door systems with sidelites and transoms, there are numerous configuration options available to meet the needs of different building types and traffic levels. Understanding how these components work together can help contractors, architects, and building owners select the best commercial

Office spaces continue to evolve, and so do the materials used to build them. In 2026, businesses are placing more emphasis on flexibility, natural light, privacy, and long‑term durability—making commercial interior doors an important part of office design and performance.

The best interior office doors are no longer selected based on appearance alone. Today’s offices require doors that support how each space is used, meet commercial code requirements, and stand up to daily wear in high‑traffic environments.

Interior Commercial Glass Doors Remain a Top Choice

Door swing direction is one of the most common points of confusion when ordering a commercial door. It is also one of the easiest things to get right once you know what to look for.

The challenge is that small mistakes can lead to ordering the wrong door, delaying installation, or even failing inspection. Understanding door swing direction early makes the entire ordering process smoother.

What Is Door Swing Direction?

Door swing direction refers to the side of the hinges and the direction the door opens. In commercial doors, this is classified as left-hand (LH), right-hand (RH), left-hand reverse (LHR), or right-hand reverse (RHR).

Once you understand how these are determined, identifying the correct swing becomes straightforward.

How to Determine Door Swing Direction

To determine the door swing direction, stand on the hinge side of the door. If it swings left, it is left-hand. If it swings right, it is right-hand.

• Stand on the hinge side of the door

• If the door swings to your left, it
