Nelson Fastener Systems Cupped Head Insulation Pin CHP

CHP studs are designed to weld through and secure blanket insulation to metal heating and air-conditioning ducts, ovens, tanks, boilers, and other hot or cold equipment. The studs are welded through the insulation for a one-step attachment. The insulation blanket may be fiberglass, rock wool, or other low-density insulation. Cupped Head Pins may also be used to anchor sprayed or gunned-on fireproofing to structural steel members in buildings to protect them from heat in the event of a fire. This protection slows the loss of structural strength to increase the time available for evacuation, and reduces the likelihood that beams will buckle or collapse. The pins may also be welded to cellular sheet metal deck to guarantee permanent anchorage of the sprayed fireproofing which protects electrical wires running through the cells, and provides added fire resistance per UL 263 and ASTM E119 standards, Fire Tests of Building Construction and Materials. In addition to securing the fireproofing, the pins also act as a reference gauge for the thickness of fireproofing to be applied.
