Dimensions
width mm 1000
length upon request from continuous production process.
Thicknesses (S)
mm 30 - 40 - 50 - 60 - 80 - 100 - 120 panels of non standard thicknesses can be supplied upon request previous agreement on minimum quantities.
External support
galvanized steel, galvanized prepainted or plastified steel; stainless steel; natural or prepainted aluminium.
Flexible support
brown felt bituminous paperboard. Due to its properties (hot binder, waterproof and insulating) the bitumen is widely used in roofing.
