We offer blast and bullet resistant structures that are ideal for use in hazardous locations. Our bullet resistant structures are built to UL standards and are available in levels ranging from 1 to 8. The structure’s panels arrest and capture the penetrating projectile, while preventing the bullet from ricocheting, as is common with steel panels.

Our blast resistant structures are available from 5 through 20 psi. They are manufactured from FSP tested and V50 rated materials. In addition, these bullet resistant enclosures meet ballistic limits specified under MIL-STD-622F and MIL-P-46593A military standards. Our explosion resistant structures are manufactured for use in classes I, II, and III, division 1 & 2, groups A to G, hazardous locations classified under OSHA standards.

Speed Space modular structures are ideal for guardhouses in secure facilities. The bullet resistant structures can be provided with transaction windows, dip trays, fully enclosed package receivers, and drawers. While our modular buildings feature enhanced anti-ballistics for multi shot protection, their panels carry a standard 1-hour fire rating.
