Side Sliding Munitions Storage


Our side sliding blast door systems are available in many configurations to meet your specific requirements. Having built side sliding blast doors to the standard Type C,E and F magazines, "Stradley" and several custom designs we are confident that we can fulfill you blast door requirements.


Doors are designed using CAD and structural engineering software. Door frame structure and connection designs are certified by an independent engineer (if spec drawings are not supplied or further design engineering becomes necessary). Blast loads are calculated using U.S. Army Corp of Engineers supplied software to insure the loads are correct and meet Government requirements. Door frames are engineered using structural steel and cold formed members per AISC and AISI codes. While usually insignificant when compared to the blast loads, wind loads are calculated using your location and building size for the most accurate structural loading possible. We don't make an assumption on the wind load by using an arbitrary standard, we verify every time.


Door components are manufactured to the highest standards and designed to be bolt together where possible and allowed, avoiding costly delays due to welding inspections and the availability of certified welders in the field. Doors are fully assembled, welded and coated at our facility, ensuring a timely delivery and installation to the job site.

Support Trolley

Our support trolley wheels are machined in house on CNC lathes and assembled using taper roller and needle roller bearings to transmit the vertical forces imposed by the weight of the door and the lateral forces imposed by wind, seismic and blast loads (when wheels are meant to restrain the door instead of guide angle or catch). Support wheels are supplied with grease fittings installed on the support axles. Support trolley is manufactured in house to ensure the best designed trolley possible. Trolley is fully assembled and wheel bearings are greased prior to shipment.

Drive System

Drive motor(s) is installed onto a mounting plate that is adjustable for chain tension. Drive motor has a worm gear drive gearbox and is equipped with a motor brake that is directly mounted to the drive motor for the Chain drive features an overload clutch to prevent damage in the case of overloading. Overload clutch is easily released, allowing manual operation in the event of a power failure. Drive motor is also equipped with a manual chain fall for operating the door in the event of a power outage. Smaller doors are supplied with the chain fall as standard with the option of adding a drive motor. Please contact us for more information on the drive system supplied for your size/type of door.


Weatherstrip is 1/8" cloth inserted epdm. Weatherstrip meets military specifications for durometer, UV resistance and incidental exposure to paint thinners. Retainer bar is fastened by zinc coated self drilling screws every 8" for a secure seal without oil canning of retainer bar. Retainer bar is easily removed for replacement of weatherstripping if it becomes necessary. Leading edge bubble seals allows for 4" of compression.

Electrical Controls

Door control panels are manufactured in house using only the highest quality UL listed components. Door control systems utilize electromechanical relays that are highly resistant to electrical interference and have no programming that can become corrupted requiring service. Door control systems also utilize drive system mounted rotating limit that is connected to the door drive chain sprocket. This design allows the overload clutch to slip without losing limit switch timing. Interior door control buttons supplied are hazardous location approved. Door control systems can be supplied ranging from 12VDC to 600VAC. Variable frequency drives are available for custom tuning or varying of door drive speed. Variable frequency drives come with variable speed buttons with 3 adjustable speed settings standard, 5 speeds as an option.

Standard options

Timer delay with safety noisemaker and/or strobe light, safety edge with delay and/or auto reverse, personnel door frames and safety interlock sensors, explosion proof drive system, air drive operating system, hydraulic drive operating system. Door drive motors and control panels are fully assembled, wired and tested at our facility prior to shipping.

Please call with your custom option requirements, we are here to create the system that meets your needs and your imagination.
