If you’re a new or seasoned business owner, you’ve likely needed to repair or install commercial exterior doors. Choosing the right doors is not just about aesthetics; it’s about functionality, security, and compliance with local regulations. With so many new options available, from security features like keyless entry to energy-efficient double-glazed glass panels, it can be overwhelming and difficult to know what is best for your business. 

This comprehensive guide will walk you through the various types of commercial doors available, their benefits, and how to select the best option for your specific business needs.

Types of Commercial Doors for Businesses

There are many types of commercial exterior doors, each built for different environments and different use cases. Here is what you need to know about each type, and what their features are best utilized for. 

Overhead Doors

Also referred to as sectional doors or commercial garage doors, they are made up of panel sections connected with hinges. As the door opens and closes, wheels at the edge of each panel roll inside a vertical track on each side of the door opening. 

These doors are commonly made from steel, making them strong and durable options for businesses. They also come in a variety of sizes, large enough to accommodate anything from forklifts to semi-trucks, and are standard in warehouses, loading docks, and any facility that requires a large, secure opening.

Rolling Doors

Rolling doors, also known as roll-up doors, consist of numerous horizontal slats that roll up into a coil at the top of the door opening. These doors are ideal for businesses with limited ceiling space because they take up much less space than traditional commercial overhead doors.

They come in a variety of configurations, such as rolling grilles for security and airflow or insulated rolling doors for better protection from the elements. Rolling grilles are a popular choice for retail storefronts that want to remain visible after-hours, but have an extra layer of security. 

Metal Doors

Metal doors encompass a wide variety of commercial doors and are by far the most common door choice for businesses. They include hollow metal doors, a lightweight and durable door solution, as well as steel doors, and more. 

Metal doors are unique for their limitless customization options. They can be fixed with windows, louvers, push bars, specialty locks, and much more. Metal doors are the standard choice for fire-rated door applications, such as emergency stairwells, for their ability to withstand high heat for long durations of time.

Glass Doors

Glass doors are typically an aesthetic choice for retail stores, offices, restaurants, and more. They can be made from glass only or fitted with aluminum hardware for better durability and insulation. 

Glass doors for businesses are an inviting choice that opens up your space and lets in lots of natural light. And, despite being made of glass, they can also be fitted with security features to prevent any issues or break-ins. Tempered glass, laminated safety glass, and reinforced framing options are all available for business owners who want added safety and durability.

Automatic Doors

Automatic doors are most commonly utilized in buildings that need to accommodate both high foot traffic and ADA compliance, like medical offices, hotels, and restaurants. They meet ADA compliance standards by providing an entry point that eliminates the use of grasping, twisting of the wrist, or pinching to open. 

Automatic doors can be customized with a range of different options, including sliding, swinging, or revolving doors with adjustable opening speeds. For businesses looking to prioritize accessibility and the customer experience, automatic doors are the most straightforward option available.  

Specialty Door Options

They can be outfitted with a range of custom features, like keyless entry systems or energy-efficient insulation, to optimize your door for maximum performance. Below is a list of features that can be customized and their function.

When to Replace or Repair Your Commercial Exterior Doors

Commercial doors are built to last, but high foot traffic, heavy usage, and exposure to the elements can take a toll.Here are some signs and common issues that may mean it’s time to get your commercial exterior doors replaced or repaired.

Damage to the Door:

Visible damage, such as cracks, dents, or holes, are a good indicator that your exterior door needs some attention. Compounding physical damage can result in more costly issues over time, so resolving them quickly is the most effective way to extend the lifespan of your doors. 

Difficulty Opening the Door:

A door that sticks or has malfunctioning entry hardware is not just a minor inconvenience; it is a serious security and safety risk. These issues are most commonly caused by hinges, locks, or a frame that needs to be replaced. It is important to address these problems as soon as they arise to prevent potential fire hazards or unauthorized entry to your building. 

Drafts or Leaks:

A door that lets in an excessive amount of outside air or water can result in costly energy bills or lead to water damage. If you notice a draft or pooling water after rain, the door seal has most likely been compromised and should be inspected promptly.

Outdated Appearance:

The entrance to your building is often the first impression of your business, and contributes to the overall look and feel of the building. If you are considering a renovation or have recently renovated, replacing your exterior commercial door is a straightforward way to give your building a fresh new look.

Outdated Hardware:

Entry hardware like keycards, pin pads, and maglocks can degrade over time. Hardware that is aging or underperforming is worth replacing for both security purposes and day-to-day convenience of anyone entering your building. 

How to Choose the Right Commercial Door For Your Business

After exploring the various commercial door options available, you may discover that several options could be a good fit for your business. Below are a few key considerations that can simplify your decision-making process, and ensure you invest in the right solution for your operational needs.

Assess Your Business Needs

Consider the primary function of the door. Does it need to be highly secure, fire-rated, or visually appealing? Assessing your specific business needs will help you narrow down your choices. Make a list of your top priorities and concerns for your doors and see what checks all the boxes.

Consider Location and Environment

The location of your business plays a crucial role in your choice of door. For instance, businesses in areas prone to severe weather might require doors that are robust and can withstand such conditions. Different materials, door types, and hardware options can vary in their durability.

Consider Your Budget

Determine your budget for the purchase and installation of the door. Keep in mind that investing in a higher-quality door might save you money in the long run due to lower maintenance costs and better durability. Typically, investing more into your doors upfront saves your money over time in terms of energy bills, maintenance, and repairs.

What to Look For in a Commercial Door Company

Selecting the right commercial door company is just as important as selecting the right door for your business needs. Different companies have different specialties, distributors, and service policies, so it’s important to know what to look for before making a decision. 

  1. Experience and expertise: Look for a company that has experience installing and repairing the specific types of commercial doors your business needs. They should be knowledgeable about their services, able to answer your questions with confidence, and capable of tailoring their recommendations to your situation. .
