Frequently Asked Questions

How do I know what door package to choose?

Your door package should be specific to your facility. Each facility has different considerations and exposures that it must deal with; amount of moisture and corrosion, contamination, dirt and other elements both inside and outside the opening, noise, security, amount and direction of traffic and the list just goes on.

How do I measure headroom?

What's a Full Vision Section ?

A full vision section includes acrylic (or plexiglas) as the panel material and allows full visibility through the door. Most commonly used with polycarbonate doors, it is constructed with two 1/8" acrylic sheets forming a 5/8" thick insulated panel. Used instead of our normal polycarbonated panel that only allows around 62% visibility; it is ordered as an option with our complete Survivor Polycarbonate Doors. Most customers prefer to install them in their door as the second or third section especially on the entrance side of their operation.

Polycarbonate, Lexan, Plexiglass, Acrylic, Lucite ... What's the difference?

Polycarbonate and Lexan are the same material, with Lexan being is a brand name. Acrylic Plexiglas and Lucite are also the same material with Plexiglass and Lucite also being brand names. Polycarbonate has characteristics that offer great flexibility, memory and strength, but it scratches easily. It is the same material that bullet-proof glass is made of. Acrylic is much more brittle and cracks easily with a sharp impact, but it doesn't scratch easily making an ideal material for full vision doors and sections.

Why should I choose stainless steel over galvanized track?

Durability. Contrary to what many believe, galvanized track will rust and corrode over time. Galvanizing is a zinc coating adhered to steel products through an electro-chemical process. Galvanization can and will wear off and expose the base material to corrosion which will eventually migrate to other parts of the product. Stainless Steel track includes chromium, nickel and molybdenum within its base composition which cannot wear off even when exposed to corrosion or wear. Galvanized track is still a great choice if you are on a budget and don't anticipate extremely high moisture or exposure to corrosion, but stainless steel track handles just about any exposure.

Bearingless rollers, bearing rollers... What?

Bearingless Rollers are a good choice for light weight, low-cycle doors and are a good choice for areas that may have excess moisture. Rollers with a sealed bearing like the Magnum Roller, should be used with heavier and higher cycle doors and they have a much higher load capacity that handles the rigors of extra door weight and abuse.

Why did my salesperson spec out two different sizes of rollers?

They did that to protect you and your customer. The longer stems are placed in the corners of the doors to prevent door derailment. If the door is hit it won't come out of the track and potentially hurt anyone.
