27/200 trapezoidal form is the most economical and common form. It can be produced in various thicknesses and colors ranging from 0.40 to 0.80 mm, painted or unpainted with the coilcoating system from galvanized sheet or aluminum. The net coating area is 800 or 1000 mm. It can be cut to the desired lengths. The maximum length is 15 meters.

ADVANTAGES OF GALVANIZED TRAPEZOIDAL SHEET:

  • Galvanized trapezoidal sheet can be produced with a 38µm film coating.
  • Galvanized trapezoidal sheet has high resistance, it does not break or crack.
  • Galvanized trapezoidal sheet is resistant to fire and heat, it does not burn.
  • Excellent heat insulation can be achieved with the Sandwich systems done with polyurethane injection or insulation materials on galvanized trapezoidal sheet.
  • Galvanized trapezoidal sheet can be easily transported and can be easily painted. The ability to be painted provides a decorative appearance as well as a long-lasting coating material.

  • Galvanized trapezoidal sheet can also be produced in painted form in the desired sizes according to user request.
  • The values given in the table above are provided for preliminary information, the loads that corrugated sheets can carry should be calculated by the user.
  • The values are calculated based on a continuous beam shape and the safety stress is 1200 kg/cm2. The individual load should not only come to one point.
