Nucor Ridge Vents for Steel & Metal Buildings

Nucor Ridge Vents come completely assembled for ease of installation. The ridge vents supplied by Nucor are of a low profile design to provide gravity type ventilation. Because gravity ridge vents are designed to allow free airflow, some penetration of water during blowing rains is to be expected.

Standard available finishes for the ridge vents are polar white and Galvalume®. Other colors may be available at an additional cost. The ridge vents can be used both with Nucor Classic Roof™ and Nucor CFR™ roof systems. Nominal ridge vent length is 10’-0”. They have flat skirts for both Classic Roof and CFR systems and are attached to the major ribs (or end dam on the CFR) with self-drilling screws. Ridge vents are available with 9” and 12” throats. Bird screens are provided as a standard.
Nucor Ridge Vent

Nucor metal building ridge vents can be ordered as continuous or single units. Exterior parts are 26 gage painted or Galvalume Interior parts are all made of G90 galvanized steel. The substructure consists of 10 gage saddle straps with interior baffles of 24 gage steel. Lifter arms and damper slides are made of 18 gage steel. Manual operation is through activation of a pull bar which is attached internally to bell cranked type lifter arms connected to the damper with Teflon coated pins through the damper slides. Dampers are spring loaded to remain in the open position until the pull bar is operated and locked in the closed position. Dampers operate in a vertical manner. Each vent is opened by a pull chain that extends approximately 12” below the roof unless noted otherwise on the order documents. Other opening mechanisms are available at an additional cost upon special request.

Nucor ridge vents should not be placed closer than 5’-0” to the endwall steel line to allow room to properly flash the building. For example, a 90’-0” long building with ridge vents required the entire length should have no more than (8) units.
