Ventilation Options

Steel Metal building ventilation is necessary in all buildings and especially important in metal buildings. The type and amount of ventilation for a metal building depends on its size, shape, location, and purpose. Ventilation is very important in order to control the interior quality of air, removal of summer heat and elimination of condensation in cooler weather which can lead to rust and deterioration of insulation. Buck Steel offers several different types of accessories used to ventilate metal buildings without HVAC systems such as, ridge vents, circular vents, louvers and roof jacks.

Circular Vent

Standard round gravity ventilator with a 20” diameter throat size, 26 gauge inner and outer bands, and rain shield. Base assembly is assembled with 4 pre-formed baffles into a simple yet sturdy ventilating unit. The design achieves a free unobstructed flow of ventilated air. The addition of a vertical-lift damper completes the weather tightness of the unit. The damper is supported in the open position by a 5’ long pull chain. Assembly is completed by the installation of a 4 x 4’ bird screen in the opening between the inner band and the rain shield to resist the entry of birds into the vent area.
