Why a Heavy Duty Sectional Door?

Heavy duty sectional doors provide the perfect degree of temperature control, protection and safety – no matter what your organization requires. In most industrial spaces, collisions between forklifts and doors are common. A heavy duty sectional door provides breakaway construction that gives in both direction and can easily be reset by team members.

Heavy duty sectional doors from Calder Doors are available with polyurethane and polystyrene insulation, or with no insulation. Ensure safety, productivity, thermal efficiency and design aesthetics when you get a high-quality heavy duty sectional door from Calder Doors.

The Calder Doors Advantage

Calder Door & Specialty Co. has served as Lancaster’s trusted option for more than 100 years.  We are eager to help you identify and install the perfect heavy duty sectional door for your business. Contact us today for a free quote!



This unique series can be a single section within standard doors for increased vision, or can be all glass structured within the aluminum frame. The frame can be powder coat painted to match your facility, and the glass is available in insulated translucent polycarbonate, plexiglass, wire security glass, or standard DSB glass. Interior track is available in corrosion resistant powder coat finish, and counterbalance helical torsion spring galvanized for severe environments. Sized small enough for a single car, or large enough for an earth mover.

Why Choose a Full View Door?

Full view aluminum doors are designed to allow unrestricted visibility both inside and out. That means your team members can see outside and your customers can see in. Another benefit of full view aluminum doors is that they allow the maximum amount of sunlight to pass through, creating a brighter and more pleasant work area.

We Can Match You With the Right Product

With one of the most knowledgeable teams in the area, we have the resources necessary to find creative solutions to any engineering challenge. We can also perform every installation to the highest standard of quality possible. For more information about our full view aluminum doors, or to request a quote, call us today.


Rolling Steel Service Doors


Benefits of Rolling Steel

A rolling steel service door is a highly durable heavy-duty option for any business. They offer various advantages for long term usage such as added security, lower cost of ownership and fewer moving parts than traditional sectional type doors. Known as the industry’s workhorse, rolling steel service doors have become the favored door in severe environments.

Choose from a wide range of materials and configurations, including insulated and non-insulated models. Insulated doors are worth the upgrade if you want to save on heating and increase the comfort of your employees year-round. Non-insulated models are more economical while still delivering exceptional durability. Need assistance choosing the best door installation for your needs? A Calder Doors representative will be happy to help.

The Benefits of Knock-Out Doors are Many

If your facility is like most, your dock doors are taking a beating day in and day out. The cost associated with damaged sections on a dock door is far more than you might think.  First, there is the expense of replacing door sections, but more costly is the downtime that you experience with that dock bay being out of commission. When your dock door is damaged, you cannot ship and receive freight that is needed for you to run an efficient business.  In some cases, the damage creates a safety concern as you may not be able to lock/secure the door properly during off hours.

Designed to Take a Punch

Our Knock-Out Sectional Doors are the industry’s most rugged door, designed specifically for severe applications where other doors fail.  The Knock-Out design eliminates severe section damage, track damage and performs better in high wind load conditions.  When our Knock-Out doors are hit, the heavy-duty retractable plungers allow door to release from the opening without damage.  It requires no tools to reset the door back into the tracking. Knock-Out Doors available in 1-3/4”, 2” Thick, and 4” Thick Insulated. Also available in a Universal Superflex Section option to retrofit existing Doors.
