Capabilities
Spray Applied Fireproofing
Rated protection applied and documented correctly the first time.
Fireproofing is inspected work. We build for the inspection.
Spray applied fire resistive materials on structural steel and decking, applied to tested assemblies with thickness and density documented throughout.
Sequencing matters as much as application. Caston plans fireproofing around the trades that follow it.
High-rise and institutional steel packages delivered with clean inspection records.
