Sep 16, 2019

A Detailed Comparison of Rolling Steel Doors and Commercial Sheet Doors 

Due to their basic similarities, both rolling steel and commercial sheet doors share competitive advantages in the commercial industrial marketplace that make them superior choices in the overhead door industry. Some similarities include being made from quality steel, operating with similar functionality, and having long-preforming, easily-sustainable life cycles. But what makes the two doors different and how should you choose between them? That all depends on product application which we'll explain in greater detail below.

Application Comparison from Rolling Steel doors and commercial sheet doors



Rolling Steel Doors, also known as slat doors, are coiling doors commonly found in commercial and industrial applications. These overhead doors are constructed of narrow thin strips of steel that interlock forming a strong and continuous curtain. Interlocking steel slats minimize vulnerability through increased strength and durability, making rolling doors ideal for heavy-duty, high-cycle applications. Rolling steel doors are often found in industrial buildings involving production, storage, and the distribution of goods.

Available in a wide variety of models, sizes and color options, rolling steel doors can be customized to meet your exact design needs, from aesthetics to functionality. A full-line of rolling steel doors range from service doors and fire rated doors to counter shutters, rolling grilles and more.

  • Commercial Slat Doors
  • Heavy Duty Service Doors
  • Fire Rated Doors
  • Fire Rated Counter Shutters
  • Insulated Service Doors
  • Counter Shutters

Rolling steel doors are often the answer if your building requires specific performance needs such as design pressures or fire ratings.


Commercial Sheet Doors are constructed of larger sections of corrugated steel, lock seamed together to create one continuous curtain. There are many models of sheet doors ranging in design to suit different applications. Although commercial sheet doors can be used for a variety of applications, they're typically designed for commercial settings ranging from light to medium duty such as garages, warehouses, and commercial facilities.

With the right design, commercial sheet doors can be easy to install , operate and maintain. 

Choosing the right door based on Key Differences:

  • Construction - The biggest difference between rolling steel doors and commercial sheet doors is how they're constructed. Rolling steel doors are constructed of many interlocking steel slats, and commercial sheet doors are constructed of corrugated sheets lock seamed together. 

  • Application - Commercial sheet doors are ideal for commercial applications ranging from light to medium duty while rolling steel doors are ideal for heavy-duty, high-cycle industrial applications.

  • Price - With reduced material, labor and maintenance costs, you can access significant savings over time with both rolling steel and commercial sheet doors.

  • Repair - When it comes to repairing damage, rolling steel doors are cost efficient to repair thanks to their extended service cut outs and versatile steel slats. Their unique design allows you to pull the curtain out of it's guides to repair and replace individual slats that are subject to damage.
