These specially designed vents are great for underfloor, in wall and sofit ventilation of your steel building. Corro VENTS address that problem of how do we vent the structure neatly when we have a corrugated or Custom Orb wall? They can be supplied to suit horizontal or vertically clad walls. These vents work with all standard Custom Orb and Corro profiles (not mini orb). These vent plates are available in Zincalume, Galvanised (Gal) Colorbond and Stainless Steel(call us). Vents come supplied with pop rivets and spark excluding mesh for BAL purposes. Minimum order quantities of 6 vent plates applies* ?

  • 150 x 150mm Square
  • 150 x 300mm Rectangle
  • 300 x 300mm Square
  • 200 x 200 Square for Trimdek, Monoclad, Trimclad
  • 200 x 300 Rectangle for Trimdek, Monoclad, Trimclad

How to Order –  Minimum order is 6 vents. From the drop down menus, please select the pack sizes that suit you best? Enter in the text box what colorbond colour, Zincalume or Gal you require? You may mix your colour choices if you wish. Then let us know if you are mounting to horizontal Corro or vertical Corro? If you are ordering 150 x 300 vents we also need to know the orientation of the vent?

Drilling Vent Holes – When installing we recommend drilling the following number of 25mm vent holes in your cladding rather than chopping out a section this is much better for the structural integrity of your cladding.

  • 150x150 = 6 x holes in the pan
  • 150x300 = 12 x holes in the pan
  • 300x300 = 22 x holes in the pan
  • 200x200 TD vent = 8 x holes in the pan
  • 200x300 TD vent = 12 x holes in the pan

The airflow for these vents is measures in millimetres square. The chart below indicates the airflow per vent and to help we have listed total airflow per 6, 12, 24 & 36 vents and for the different size vents.
