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!

Chase Bird Doors Keep Your Facility Cleaner

So we all know this is the season for all of those little bugs to come out and play, as well as the birds. The hot summer temperatures are upon us and you may find that more and more birds are resorting to your garage or business for shelter and shade, which can lead to big problems – birds can be more than a nuisance in your facility, they can also cause problems with machinery and their presence and droppings can create health hazards.  

One of the best ways to keep birds out of your facility is to keep the doors and windows closed or properly screened. However, this isn’t practical in many large, un-air conditioned facilities where large rollup doors are left open to provide for ventilation. In these situations, our DuraShield Bird Screen Door can help you get the best of both worlds: with the DuraShield door in use, birds (and trespassers) are kept out, while fresh air sails through. 

Bird Door ExteriorDuraShield Bird Screens are made from a durable, vinyl encapsulated woven polyester mesh that is resistant to mildew and color fading. The bird mesh standard material utilizes netting, a special oval shape weave with nine holes per square inch to allow for good air-flow while keeping birds out. The panel includes horizontal fiberglass stiffeners and a weighted bottom pocket to remain stable in wind and keep crawling critters out as well.

Bird Door VinylDuraShield doors are easy to operate and maintain – manual doors roll up and down easily with a chain pull system, while motorized operation is available for more convenience (especially helpful with high-traffic doors).

We wish you a bird-free facility this summer, and ask that you connect with us via FacebookTwitter, Google Plus and LinkedIn, or leave us a note below! We also wanted to share some additional measures that you can take to help prevent birds from becoming a problem at your facility, courtesy of FoodManufacturing.com:

Inspect the exterior of the facility at least monthly. Look for evidence of pest birds such as droppings, feathers or nesting materials. Focus inspection efforts on finding those conditions which can provide food, water and shelter. Also inspect for access points such as openings around dock doors and levelers. The inspection must cover all areas of the plant exterior including ground level and roof. Use the information uncovered in the inspection to further educate staff and correct bird-conducive conditions.

Establish a regular clean-up schedule. Food is one of the major attractions for birds.  Food spillage around dumpsters, silos and rail unloading areas are some examples where birds may find food. Establishing a regularly scheduled clean-up is essential. Roofs and product accumulations in these areas should also be checked. Roof areas can be difficult to clean, especially if there is a gravel layer on top of a membrane roof. But product can be present in these areas through equipment malfunctions. Inspect both high and low for food sources and eliminate them.

– Eliminate accessible water sources. Water will also attract birds and provide an essential need. Birds need a readily available source of drinking water. Parking lot pot holes, poorly designed drainage systems and other sources of standing water can provide the drinking water. Eliminate these sources whenever feasible.

Evaluate structures and landscaping. The last condition to focus on is harborage. Pest birds, like the English house sparrow, will readily build their nest in structures like gaps in exterior walls. Pigeons will seek harborage on ledges, especially when there is some cover provided over the ledge. Inspect these nesting opportunities and seal or use bird management devices to repel or exclude birds. Bird netting is often used to exclude nesting areas like those found underneath overhangs and canopies.
