Installing a new commercial door is a big investment that directly impacts your business security, efficiency, and curb appeal. Whether you are upgrading your current entryway or installing commercial doors for the first time, proper preparation ensures a smooth process and long-lasting results.

At CDF Distributors, we provide high-quality commercial doors with fast nationwide shipping. To help you get ready, here is a guide on how to prepare for your upcoming installation.

For a straightforward installation, an experienced contractor can usually complete the job in about thirty minutes to an hour. More complex projects, such as double doors, specialty hardware, or fire rated doors, may take longer.

Hiring a skilled contractor ensures the installation is done correctly the first time and keeps business downtime to a minimum. If you need reliable doors that ship quickly, explore our in-stock steel doors and wood doors.

It is not far-fetched to say that when you walk into the building, your eyes might be drawn to the décor, flooring, and even the lighting. But have you ever noticed the humble door frame, which plays an important role but is often overlooked? Even during the renovation or building of a property, door frames are often not the focus of attention, but rather the doors themselves. Yet this small detail carries more weight than most people imagine.

Door frames are not only for aesthetics, but they also determine durability, security, and functionality. They are the backbone of your door system, quite literally. Door frames support the weight of the door, aligning it perfectly, and contributing to insulation and safety. Although you will find numerous options in the market, the best door frames boil down to two options: knockdown (KD) steel door frames and welded commercial metal door frames. CDF Distributors offers both options, giving builders and contractors the flexibility to choose the best

Every year, businesses in the U.S. lose nearly $45 billion to theft. While some incidents happen during operating hours, most occur when businesses are closed. Even more alarming, an estimated 56% of burglaries involve forcible entry, proving that many standard commercial doors can be bypassed with ease.

Protecting your property starts with reinforcing your entry points. A strong, secure commercial door can help prevent costly losses and give you peace of mind. Below, we’ll cover five practical ways to reinforce your commercial door and safeguard your business.

No commercial property is completely immune to break-ins. By strengthening your doors, you create a serious obstacle for criminals and reduce the likelihood of forced entry. Even simple upgrades can save you thousands in damages and lost inventory while protecting your employees and customers.

To keep your business compliant and protected, it’s also important to understand building code laws

Since the 1940s, technology has significantly improved the manufacturing process of commercial hollow metal doors. The manufacturing process involves nine steps before a metal door is shipped to a job site for installation. First, the process begins with the raw materials. The standard material for a commercial metal door is galvanized steel.

Galvanized steel is a steel surface that has received a galvanized coating, which has been annealed. Galvannealed steel starts with a galvanized coating, where the steel is dipped in zinc to protect it from rust. After coating, the steel is heated (annealed) to allow the zinc to bond with the surface. The result is a corrosion-resistant matte finish that holds paint well.

Steel shaping for commercial doors involves several key steps:

• Large steel sheets are cut down to the required door size.

• The sheets are bent and formed into the outer shell of the door.

• Reinforcement channels are shaped and

Selecting the right warehouse doors is more than just a design choice. It directly impacts your facility’s productivity, safety, and security. A high-quality warehouse door should open smoothly, stay secure after hours, and meet the unique needs of your operation. At CDF Distributors, we make it easy to find durable and affordable doors for warehouses, factories, and commercial buildings.

In this guide, we will cover the key factors you should consider when buying new commercial doors, including foot traffic, safety, measurements, and environmental conditions.

The amount of door traffic in your warehouse determines the type of door and opening mechanism you will need.

• Low-traffic doors that open once at the start of the day and close at the end do not need to prioritize ease of operation.

• High-traffic doors that open 50 to 100 times daily require smooth functionality to maximize workflow.

For office spaces, break rooms, or high-traffic interior areas,

Different commercial door locations call for various materials and features. For example, interior commercial doors do not require the same level of durability and security as external doors. Your back exits should provide security for your building and an easy way for occupants to leave the premises. Let’s look at a few examples of the best door options for back exits.

There are many different door varieties to choose from, from wood to metal to glass. While glass doors or doors with glass inserts are an attractive option for the design of your business, glass is generally not a suitable material for backdoor exits. 

Back exits are often not visible and can be a tempting place for thieves and unauthorized visitors to break in. In fact, nearly a quarter of break-ins in 2025 happened through the back door. Glass, by its nature, is more vulnerable than other types of doors. For these back exits, it is best to choose a material such as metal, wood, or another solid material.

One of your worst nightmares as a business owner is to watch your building go up in flames. Unfortunately, this happens more often than you might think (approximately 10% of insured small businesses!). Research shows that between 2008 and 2017, more than 100,000 nonresidential fires were reported every year and led to about 95 deaths, nearly $3 billion worth of property damage, and 1,200 injuries.

Commercial fires can spread fast if your building isn’t fireproof. This is why it is wise to install fire-rated doors versus non-fire-rated doors. Here’s a rundown on doors and how they can help you to protect your business assets in the event of a fire. Let’s get started!

Fire-rated doors save lives. They also minimize costly property damage. They work by containing flames, smoke, and radiant heat to one area. At the same time, they provide a safe exit route for people inside the building.

In a fire-rated door assembly, each part has a specific role:

Commercial entry doors are more than just access points. They are the first line of defense for your building. Whether you manage a retail store, office, school, or financial institution, installing entry doors that comply with building code requirements is essential for safety, accessibility, and security.

In an emergency, entry doors also serve as the primary method of exit. If they are not up to code, you risk endangering occupants and violating compliance laws. Below, we will break down some of the most important building code laws that apply to commercial doors and why they matter.

Building codes vary by state, city, and municipality. While there is no single global law, many jurisdictions adopt parts of the International Building Code, which is published by the International Code Council and updated every three years.

Chapter 10 of the International Building Code, titled Means of Egress, covers critical details such as:

• Minimum door sizes and clearances

When doors aren’t weather-tight, they let in wind and moisture. That leads to uncomfortable spaces and higher utility bills. Fortunately, there are some techniques you can use to better weatherproof the commercial doors on your business. Take a look at five of the most effective.

A sweep is a material installed at the bottom of a door to prevent drafts from entering. Its purpose is to close the gap between the door and the threshold. That stops air and moisture from getting through that space and causing a draft. If your door didn’t come with a sweep, you can easily install one.

Here’s how to properly install a door sweep:

• Measure the width of your door to ensure you buy the correct size sweep.

• Mark and cut the sweep to fit if it’s too long.

• Position the sweep along the bottom edge of the door so it seals the gap evenly.

• Drill pilot holes if required.

• Screw or snap the sweep into place.

• Test the door to make sure it opens and closes smoothly without dragging.

Once you install
