Blast-Resistant Doors

Metal Manufacturing Industries has manufactured swing-type blast-resistant door and frame assemblies since 2012.

Our assemblies are built in accordance with the standards of the Hollow Metal Manufacturers Association (HMMA).

Blast-resistant door designs reference the following codes and engineering references:

Mexican Complementary Technical Standards for Structural Design Criteria and Actions (NTC).
Seismic Design, Civil Works Manual, Federal Electricity Commission (CFE).
Wind Design, Civil Works Manual, Federal Electricity Commission (CFE). Complementary Technical Standards for Seismic Design (NTC).
Steel Construction Manual, American Institute of Steel Construction (AISC).
Mexican Institute of Steel Construction (IMCA) — Steel Construction Manual.
Design of Steel Structures, Bresler, Lin, and Scalzi.

Ideal for industrial and security applications, petrochemical refineries, laboratory facilities, public buildings, and military projects.

MMI blast-resistant doors are engineered to resist three pressure ranges:

• 1 BAR — 14.5 PSI — maximum size 80″ × 80″
• 2 BAR — 29 PSI — maximum size 80″ × 80″
• 5 PSI — special 3 m × 3 m opening size

These doors swing inward — that is, they open toward the “hot” side where the blast event would originate. They are not exit doors.

The structure receiving the blast-resistant door must include adequate reinforcement in the wall, floor, and slab — designed for the specific threat level to which the assembly will be exposed.

MMI supplies all hardware and accessories required for correct installation and operation.
