Chase Duralite doors are well known for being the toughest traffic doors on the market, and for good reason. They are rotationally molded, meaning they don’t need mechanical fasteners or adhesives to keep different layers of material together (such as a frame, wood, laminates, and composites, you get the idea).
It’s just that the adhesives and mechanical fasteners used in a laid up door don’t have much “stretching” ability upon large impacts, so if the door is used in situations where they are subject to frequent heavy impacts like those from a forklift, they can be more susceptible to failure.
Roto Molding – Say What?
Rotational Molding, often referred to simply as “roto molding”, offers many distinct advantages when building an industrial-strength traffic door.
- The door is a one-piece hollow shell, without seams to separate or deteriorate.
- The cross-linked polyethylene we use is strong, flexible, and able to withstand exposure to solvents and adhesives.
- Non-CFC foam fills the entire core of the door, providing excellent insulation and helping the door to absorb heavy impacts with ease.
- The doors are lighter than a traditional laid up door would be, since there is no internal framework necessary.
- Since Durulite doors are sealed, they can be used in cooler and freezer environments without worry.
Roto molding a traffic door is actually a very interesting process – read more about what happens at our facility.
Why Durulite Doors?
Chase invented the roto molded traffic door in 1976 and we have sold over 500,000 since then! Every one of these doors is custom manufactured at our facility in Redmond, Oregon, where we can monitor the entire process, from raw material inputs to proper molding techniques, to make sure you’re getting the highest quality door possible.
Standard impact resistance tests have shown that cross-linked polyethylene is 5x more puncture resistant and 3x more flexible than ABS panels which are typically used by competitors.
So when you need the strongest, yet lightest door possible, stick with the name that says it all: Durulite!
