THE PROOF IS IN THE COLUMN

Black Rock Fireproof Columns save owners cost and installation time through:

  • • Factory fireproofing (in-shop labor eliminates need for field labor to apply other forms of fireproofing)
  • • Exacting quality control performed by our in-shop factory professionals
  • • Decreased long-term maintenance costs and the added durability of exterior steel shells
  • • Predictable scheduling as Black Rock Fireproof Columns are delivered to site completely fabricated, fireproofed, and ready for erection
  • • No additional trades needed for on-site fireproofing
  • • Added security and confidence of working with an AISC-certified structural fireproof column fabricator
 

Black Rock assures on-time deliveries by maintaining our own trucking fleet of 15 tractors and 40 trailers. We also tap into our network of over-the-road trucking firms whenever needed to meet owner demands.
