Round components.

Round ductwork serves as well as square ducts for air transport. Preferably the circular pipe is, the better to keep clean and easier to produce pieces of simple shapes. Round duct made of sheet and rolled galvanized steel sheet DX51D MAC with a zinc coating of 275 g / m2 with suppressed flower.


General information

Dimensions of round parts:

  • We produce circural ducts in this diameters (mm) – 80, 100, 110, 125, 140, 150, 160, 180, 200, 225, 250, 280, 315, 355, 400, 450, 500, 560, 630, 710, 800, 900, 1000, 1250. Another diameters according to the order.

Groups of round parts::

  • group I - sheet thickness 0,55 mm up to 0,9 mm
  • group II - sheet thickness 1 mm up to 2 mm
  • group III - sheet thickness 2,5 mm up to 4 mm

Group of duct tightness:

  • group of duct tightness A
  • group of duct tightness B – cementing of bottom edges and joints of duct
  • group of duct tightness C – fully cemented joints and edges including the flanges or joints and edges brazed

Types of cementation:

  • Silicone, acrylic, tekasil, polyurethane, emfimastic, fire protection, up to 300 °.

Luxuriously circular pipes made of stainless steel plate, black plate, Aluzink copper or aluminum.

Assembling the part to each other:

  • Round pipes are joined together by slip in to each other, by pressed flanges or steel flanges in standard or in tight completation (cemented).

Luxuriously can be coated pipe flanges according to customer requirements outside the dimensional table or use a steel profile flange primed. To increase corrosion resistance ductwork can protect the paint or komaxit. At the customer we can supply pipes insulated or thermal insulation, including fire covered with iron (insulation to metal).
