Due to their many similarities, both rolling steel doors and commercial sheet doors share competitive advantages in the market that make them a superior choice in the overhead door industry.

Application Comparison from Rolling Steel doors and commercial sheet doors



Rolling Steel Doors, also known as slat doors, are coiling doors typically found in commercial and industrial applications. These 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 industrial and high-cycle applications. These doors are typically seen in industrial buildings involving production, storage, and the distribution of goods.

Available in a wide variety of models, sizes and colors, rolling steel doors can be customized to fit exact design needs from aesthetics to functionality. A full-line of rolling steel doors ranges from service doors and fire rated doors to counter shutters and rolling grilles.

Rolling steel doors are the answer if your building requires specific performance needs such as fire rated doors, fire rated shutters or counter shutters.



Commercial Sheet Doors are constructed of larger sections of steel, corrugated and lock seamed together to create one continuous curtain. There are many models of sheet doors ranging in design to suit different environments. 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 and warehouses.
