METU-FORM parts have generally a nice and inconspicuous appearance and can compete with painted ductwork. They are however "industrial" ducts and our main focus remains on their function and performance more than their appearance.
The METU-FORM ductwork offers a discrete appearance: the ducts do not necessarily need to be hidden behind walls or ceilings or painted!
A consistently homogeneous surface cannot be guaranteed as production processes leave unavoidable traces on the surface.
In addition, there are no exact standards regarding the appearance of raw material surfaces.
