Weather door withstands hurricanes, twisters, storms
StormPro 320 (shown before and after storm damage) can protect community storm and disaster shelters from destructive winds and flying debris. Swing-in severe weather door is constructed of heavy-duty, 14-gauge cold-rolled steel with 16-gauge-steel stiffened core, reinforced 12-gauge channels, and welded edge seams. StormPro 361 is swing-out version. Both doors were tested at Texas Tech Universitys Wind Research Center to be in compliance with Homeland Securitys FEMA guidelines and carry UL-Windstorm labels that certify testing and approval of doors and frames for use in FEMA 320 or FEMA 361 shelter designs.
