Z-type open-sections of galvanized metal sheets can be used as structural profiles in all types of steel constructions. Their main use is to support the building shell, cladding panels, in all types of buildings.

 

They are distinguished for:
  • Excellent bearing capacity as a structural component
  • Excellent reaction to fire, category A1
  • Excellent weather and corrosion resistance
  • Acceptance of intumescent paints where required
  • Easy and fast standard mounting

 

Product parameters:
  • Cover width 140mm, 180mm and 210mm
  • Nominal sheet thickness 1.50mm, 2.00mm, 2.50mm, 3.00mm
  • Fixed lengths up to 14m, depending on the project requirements
  • Optional punched holes Φ12, Φ14, Φ18, Φ22, in any position

Open sections type Z 140, Z 180, Z 210

Z-type cold rolled thin walled open sections are manufactured on the basis of the company’s high quality criteria covering a wide range of applications. Produced in desirable lengths up to 14m depending on project requirements. It is possible to be produced with punched holes of diameter Φ12, Φ14, Φ18, Φ22, at any point with excellent precision.

 

Open sections type Z, are usually used as girts or purlins to support the side cover or top cover of the building. Obviously the number of applications of these cross sections is unlimited, provided that the static study of the structure has been issued.

Characteristic Metal Sheets

Metal Sheets

Different materials in different thicknesses are available for the production of the profiles. The metal sheets available for the production of the profile can be steel, which produced according to EN 10346 and EN 10143 as per quality and tolerances. The thickness of the metal sheets ranges from 1.50mm up to 3.00mm.

Galvanized steel sheets, without color coating
  • according to EN 10346 & EN 10143,
  • hot dip zinc protection Ζ 70 ~ 275 gr/m2
  • aluzinc protection AΖ 70 ~ 265 gr/m2

 

Different materials in different thicknesses are available for the production of the profiles. Please refer to the sales department about the available coatings and the available colors (RAL 1014 to RAL 9010).

Essential Properties

Open section type Z

Z 140 Z 180 Z 210
Nominal sheet thickness [mm] Weight per unit length * [kg/m*]
1,50 3,40 3,80 4,00
2,00 4,50 5,00 5,40
2,50 5,60 6,30 6,80
3,00 6,70 7,50 8,10

* Weight per unit length was calculated taking into account the specific weight of steel = 7850 kg/m3.

Connection/Support Options

Thin wall open sections type Z, are fixed to the structure by the standard screw connecting method. It is not recommended the use of self-drilling screws or rivets. In general, welding in thin wall sections is not applicable.

 

These sections, due to their specific design, can be flip-over and overlapped. In advance, it is not necessary to use extra fasteners and fittings for the joining of the parts, thus reducing the cost of construction. The overlap length depends on the span between the supports. It is recommended to place the joints always at the support positions (columns, beams).

 

For structural construction, the straight reduction, at the position of the holes, shall be calculated taking into account the provisions of EN 1993-1-3.
