It is important to discuss the design pressure requirements for doors and door openings with your design professional before finalizing your drawings for permit submittal as each door and each opening is building-specific. Parameters to consider when calculating door opening pressures include building height, roof slope, end zone area, center zone area, exposure classification and building classification.
In self-storage projects, there may be "factors" for reducing the standard pressure requirements. The matrix below has been calculated using these reduction factors.
As design pressures increase, so does the cost of design and manufacturing for most components used in self-storage buildings. We recommend reviewing your specific requirements with your design professional as early as possible..
Model 155
Our Model 155 is an economical choice for an efficient, performance-oriented rolling steel door. Constructed of roll-formed hot-dipped galvanized steel, the Model 155 has proven to be a reliable, practical, low-cost alternative to a slat-type rolling or commercial sectional door.
As with all MBD rolling steel doors, the Model 155 features a polyester base and prime coat for a long-lasting, durable finish, which eliminates the added expense of field painting. The Model 155 has an exterior polypropylene wear-strip to reduce friction and ensure smooth, quiet operation.
Quality design and strong construction provide flexibility for mounting to wood, masonry or steel jambs. The Model 155 is available for areas of up to 144 square feet (14 square meters), 12’ (3658 mm) wide by 12’ (3658 mm) high. It is identical in appearance to our other door models, so you can use different models on the same job site.
Model 160
Our Model 160 is the industry leader in commercial and industrial curtain doors. Engineered for frequent use and longevity, the Model 160 features roll-formed galvanized guides with a polypropylene wear-strip to reduce friction and noise. Quality design and strong construction provide flexibility for mounting to wood, masonry or steel jambs. The Model 160 is designed to fit most standard openings and is available in sizes up to 16' wide (4,877 mm wide) and 16' high (4,877 mm high). It offers value, quality and proven dependability that is unsurpassed in the industry.
Model 165
Our Model 165 wind-lock door is the undisputed industry standard for maximum security and protection from hurricane-force winds. Originally engineered to meet the tough Miami-Dade County, Florida Building and Zoning Codes, Model 165 doors have been laboratory-tested to withstand winds equivalent to 58 p.s.f. or 140+ mph (225+ km/hr). During Hurricane Andrew in 1992, our Model 165 doors performed to withstand wind loads that far exceeded the most stringent building codes.
With 10-gauge wind-locks reinforced and fastened to the curtain, Model 165 doors offer unbeatable protection with solid construction. They can be manufactured to fit openings as large as 20’ wide (6,096 mm wide) by 16’ high (4,877 mm high). Smooth operation, reliable performance, nationwide distribution and a proven track record have made the Model 165 the No. 1 choice for wind-load doors.
