Commercial doors take a beating. Every day they're opened hundreds—or even thousands—of times by employees, customers, students, patients, tenants, and visitors. Add weather exposure, moving equipment, accidental impacts, and years of routine use, and even the highest-quality doors eventually reach the point where repairs become less practical than replacement.
The challenge isn't deciding whether a commercial door should be replaced. It's understanding what needs to be replaced.
Can the existing frame stay? Should the hardware be reused? Does the replacement need to maintain a fire rating? What measurements are actually required before ordering? These are the questions that determine whether a project moves smoothly or results in delays, unexpected costs, and compatibility issues.
At CDF Distributors, we've helped thousands of customers navigate commercial door replacement projects of every size. Some are facility managers replacing a damaged office door. Others are contractors

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
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?

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.
What Are Primed Hardboard Wood Doors?
Primed hardboard wood doors are commercial flush wood doors manufactured with a smooth hardboard facing over a solid particle core or fire-rated mineral core. Before leaving
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.
What Are Commercial Doors?
Commercial doors are designed for use in public and private buildings. They provide security, durability, accessibility,
Commercial door sizes are one of the most important specifications on any construction project. Selecting the correct door width and height affects code compliance, accessibility, safety, occupant flow, hardware selection, and overall building performance.
Whether you are purchasing commercial metal doors, commercial wood doors, storefront doors, wind-rated doors, or metal building doors, understanding standard commercial door sizes can help prevent costly delays and installation issues.
This guide covers standard commercial door widths, average commercial door heights, common door size combinations, and the standard dimensions available across the most popular commercial door types.
What Is the Standard Commercial Door Size?
The most common standard commercial door size is 3'0" x 7'0" (36" x 84").
This commercial door width and height combination is widely used in office buildings, schools, healthcare facilities, multifamily housing, retail spaces, warehouses, and industrial buildings.
When planning a commercial door installation, many people ask: what is standard door size, and can it be used in a non-standard opening? The answer is yes, and in most cases, it’s the smarter approach. At CDF Distributors, we strongly recommend using standard size doors instead of ordering fully custom products whenever possible. With the right adjustments, standard doors can fit a wide variety of openings while delivering significant cost and scheduling benefits.
What Is a Standard Door Size?
In commercial construction, door sizes are standardized to simplify manufacturing, installation, and replacement. Both metal and wood doors typically come in a 1-3/4” thickness and are produced in a range of common dimensions.
