STORM PRO 361

TORNADO

RESISTANT

SEVERE WEATHER DOOR AND FRAME SYSTEM

Strong gusts of winds up to 70 miles per hour are not uncommon anywhere in the world, but sustained winds of that magnitude, or winds of higher speed, are generally associated with tornados, hurricanes, and tropical storms. 

Damage can be caused by flying debris (referred to as windborne missiles). If wind speeds are high enough, missiles can be thrown at a building with enough force to penetrate windows, walls, or the roof. 

Wind hazard maps have been developed for today's model building codes. 

An object such as a 2” x 4” wood stud weighing 15 pounds, when carried by a 250-mph wind, can have a horizontal speed of 100 mph and impact with enough force to penetrate most common building materials used today. 

The StormPro^®361 was developed to resist missile penetration for use in buildings designed as shelters to protect occupants from injury.

Applications for Storm Pro:

• Community Shelters

Doors and frames that have been tested and approved for use in accordance with F.E.M.A. Guidelines are not required to bear a label indicating there approval. Metropolitan insures the label is affixed to certify that the door you are using has been tested and approved.

THE IMPACT TEST
This test is designed to simulate the impact of air-borne debris from a Class 5 Tornado with wind speeds of 250 mph. Most commonly used building materials, including block walls, fail this impact.
