Air Ducts

All of metal ducting, manufactured in our production department, can be designed and constructed in compliance with all the main international standards (SMACNA, DW 144, ISO 15138, SOLAS, EN, etc.).

The range of metal thickness usually worked vary from 0.6mm up to 12mm.

Types of longitudinal and transversal seams are selected for the material, pressure classification and other construction details appropriate for the service, therefore air duct can be realized lock-formed or welded.

Structural penetration according to SOLAS can also be made.

We can provide CAD drawings as the key map with all pieces numbered and the shop-drawing for the duct construction.

We can offer you also Ductwork Leakage test performed according to EN-12237, EN-1507, DW143.

Our goal is to provide Attention to job estimating accuracy, job production quality and on time delivery.

Fabricated Duct Products include:

  • Round;
  • Rectangular;
  • Welded industrial;
  • Noise attenuators;

On request ducts can be supplied already insulated with lots of material as elastomeric foam, stone-wool, cellular glass, and several type of metal cladding as steel sheet, perforated sheet, mesh net, etc.

The Company has qualified welding procedures, certified by R.I.NA, for stainless steel and carbon steel, both according to European standards (EN ISO 15614) and according to American standards (AWS D1.1 and D1.6).

Fabricated metals include:

  • Galvanized steel (usually available Z275);
  • AISI 304L or AISI 316L Stainless Steel;
  • Carbon Steel such as S275, S355, and others;
  • Aluminum;
  • Copper;
  • Pre-painted galvanized steel.
