Light gauge ducting systems

Roof passage for pipe

Roof passages are standard longitudinally welded with a stitch-welder and spot-welded on a flat plate.

They are used in combination with storm collars (AAGA) to ensure a waterproof passage of a pipe through the roof of a building.

They are designed to fit ducting with edges. It might be necessary to switch to a bigger diameter If ducting with flanges is used.

Rolled stitch-welded and spot-welded sheets.
