High speed doors are exactly what they sound like; doors that open and close quickly which helps to save you and your company time. They are generally made of a fabric material such as vinyl and are usually the most aesthetically pleasing option which makes them great for customer-facing applications.
Knock out doors have the look of a traditional sectional door with one important difference; they are designed to be impacted which gives them more durability and longevity. If a forklift happens to run into the door, the panels will pop or knock out, and then those panels can simply be pushed back into place. This saves you from having to replace or repair a regular sectional door that would be damaged by such an impact.
Rolling Doors offer a simple and straightforward solution. They are usually made up of thin panels which roll up or to the side. This makes them usable with a variety of height parameters. The trade-off with this more lightweight option is that these doors have less security and insulation benefits than some other doors.
