Construction Features :

Safety Floor Planking

Slip resistant planking 13" wide, 12 gauge galvanized steel with raised perforated buttons and debossed holes protruding down. Galvanized steel floor planking above sump area for maximum corrosion resistance. Floor planking designed to sustain a minimum uniformly distributed load of 250 pounds per square foot. Floor planking and supports are removable to facilitate sump cleaning in the event of a spill.

Door for B200-B400 Provide one (42" wide x 62.5”) and B600-B1200 Provide one (42” wide x 80”) high door to facilitate the unloading and loading of hazardous material within the building. Installed with a UL Classified commercial grade keyed lockset. The door shall serve as personnel entrance and exit.

Door for B1600-B8000 Provide one 60” wide x 80” high double door to facilitate the unloading and loading of hazardous material within the building. Installed with a UL Classified commercial grade keyed lockset. The double door shall have one active leaf to serve as personnel entrance and exit. The active leaf must be equipped with a door closer available on B600-B1200 fire rated models.

Explsion Relief Panel

Used in the construction of buildings designed to store Class IA and Class IB flammables. Explosion relief panels limit the damage within an enclosed hazardous location. When the panel(s) are subjected to an explosive force, the pressure relieving panel quickly vents the force before it causes major damage. The panels are designed to release at 20 psf.

Factory Mutual System Approval

Securall Fire-Rated Hazardous Material Storage Buildings (10'H X 42'W X 9'D Max Dimensions) carry the Factory Mutual System Approval label and are constructed based upon UL Fire Resistance Ratings classification criteria. In addition, all Fire-Rated Buildings come with hydraulic operated self-closing, fire-rated doors and fire damper protected vents.

Securall Buildings have been tested to determine the amount of force they can withstand and were shown to withstand F-4 tornado force winds of 250 mph. The chart below demonstrates the wind speed that a particular length of wall will resist.

Upgrade package is available for Tornado Resistant Walls.

Securall Hazamat Storage Buildings are all-welded using 12 gauge (B1600X-B8000X Models) and 16 gauge (B200X-B1200X Models) galvannealed steel outer walls and 20 gauge cold rolled steel inner walls provide maximum durability, weather resistance, and rigidity.
