Durable Durulite Doors

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).

Granted, that’s a very good way to manufacture a door: many traffic doors (including our Proline and SC3000 series) are made this way: differing materials “laid up” into the final door assembly.

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? 

Roto Molding Def

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!

What Makes it XHD?

With StorePoint 2013 wrapping up, we thought it was a great time to clarify some questions we’ve been asked before – what does the XHD stand for, and what makes it XHD? In the case of the Durulite Retailer XHD, it means “eXtra Heavy Duty”, and it is the ideal door for busy, high volume retail and grocery establishments.

Retailer XHD To make it XHD, we build on the strength of our Durulite Retailer door, adding several features to make this door even tougher and able to withstand all sorts of abuse, from frequent personnel and carts, to manual and motorized pallet jacks and even occasional low speed forklift traffic.

For example, the upper V-Cam hinge is upgraded to a fully composite roller assembly featuring stainless steel bearings, allowing it to resist corrosion and rust over the life of the door while traveling up to 120 degrees in either direction. XHD V-Cam Hinge

The lower hinge is upgraded to a heavy duty, stainless steel lower hinge guard assembly, which not only protects the door from impact, but creates a positive hinge mount. Finally, we add a heavy duty aluminum back spine with a powder coat finish, which adds strength and rigidity to the entire panel – this allows us to offer more size options on the XHD than the standard Durulite Retailer.

Retailer XHD LHGLike its little brother, the Durulite Retailer, the Durulite Retailer XHD is made from rotationally molded cross-linked polyethylene and is filled with impact absorbing non-CFC urethane foam. With no gaps, joints or seams, the XHD is USDA acceptedUSDA_logo and is ideal for high moisture or regular washdown environments such as those found in supermarkets, food processing and cold storage facilities. Replaceable perimeter edge gaskets and an overall R-factor of 10.8, minimize energy loss between different environments within your facility.Durulite Edge Gasket

If you’ve got a busy grocery or retail environment and want the most rugged, durable door for your opening, the XHD offers you the best combination of long-term value and durability.
