MP-32/250 Roof and Wall Trapezoidal Sheet
Trapezioidal Sheets can be produced from galvanized sheet metal or aluminium, as coilcoating painted or unpainted, in various thicknesses and forms. They are used as single layer without thermal insulation or, as multi-layer roof and wall applications where thermal insulation is laid down in between two corrugated sheets.
In multi-layer systems applied by insulating between two trapezes, purlins used to determine span distance. Vapour barrier must be used on bottom trapeze to prevent water vapour and condensation. The intermediate purlin and therefore the roof load must be transferred to the carrier structure of the construction by using plates to hesitate loading bottom trapeze. Min 1 lame (thin plate) must be used in every 1 mt.EPS, XPS, Polyurethane, Rockwool or Glasswool plates are used for insulation.
In Mineral Wool insulations steam barrier must be used btw upper trapeze and insulation material. Heat bridges between the profiles that are determining the span distance and the trapezes must be prevented by insulating bands.

Notes:
. Values have been calculated using the allowable “Stress Design” method, taking self weight, imposed loads (wind load) and temperature (Δt=±20ºC) into account.
. If loads are effected as downwards l/200 and l/150 , ıf loads are effected as suction l/150 deflection limits have been used
. Values have been calculated using the steel quality fγ=240 Mpa(Yield Strength).
