Fireman’s Phone Cabinet Custom Steel Fabrication

Fireman’s Phone Cabinet Custom Steel

This fireman’s phone cabinet was designed to house a phone which enables fireman to communicate within a distressed building. Fabrication required processes and materials that would enable the box to meet requirements of various governing agencies. Bull Metal Products, Inc. is a full service sheet metal fabrication and manufacturing organization. Our 50+ years of experience and expertise in metal fabrication allowed us to creatively engage with our customer in the development this product which incorporates a number of our manufacturing capabilities.

Fabrication began with shearing sheets to sizes that will give us the best sheet yield for the flat blanks that are punched on one of our CNC turret presses. The door and back-box are made with .048” (18 gage.) cold rolled steel. The interior dead front partition is made with a .050” (16 gage) 5052 aluminum alloy. Components were formed utilizing brake presses to tolerances as required by product design.

The formed components were then joined with spot welds. This assembly also required the insertion of various threaded inserts; Pem studs, nuts, and stand offs, which were inserted using a Pem insertion press. The completed component parts (door, backbox, deadfront partition) were degreased and prepped for powder coating with the application of iron phosphate primer. Our BMP # 161 red textured powder coat was applied, followed by application of the screen-printed image on the door. All of the work involved in producing this product is completed in-house allowing Bull Metal to control and monitor each and every step in production of this cabinet.

Maintaining quality is an integral part of all of our fabricating and manufacturing processes. We perform dimensional and visual inspections at every step of production, ensuring that parts not only meet your specification but our own stringent requirements for quality.
