Rectangular ducts and fittings made of plastics are
manufactured from sheet using the welding method. The
sheet thickness of which the ducts are made depends on
the length of the side and the circumference of the duct.
The thicknesses are selected in such a way as to ensure the
appropriate rigidity of the duct. On top of this, additional
reinforcements are applied. The dimension of the duct is the
external dimension.

Depending on the type of termination,
the system of ducts made of plastic materials is joined by
welding (female end), screwing (flanges) or gluing (only PVC).
Minimum duct size: 300 x 280 mm.
Standard duct lengths: 1000, 1500, 3000 mm.
Other lengths available upon request.
