TR40/1020 profiled sheet
Material and thickness to suit the building
TR40/1020 is used most often on industrial and commercial halls, warehouses, canopies and other technically demanding buildings.
It is available in hot-dip galvanised steel (Zn) or aluminium (Alu), in several thicknesses and RAL colours. The right material and thickness depend on the purpose of the building, its structural requirements and the expected durability.
On galvanised sheet the basic corrosion protection is the zinc coating (g Zn/m²), which determines how the material resists different environments. The aluminium version is lighter and resists corrosion well; it is meant above all for specific buildings or more demanding environments. For larger projects we can also make other colours and special thicknesses.

DRIPSTOP®
The DRIPSTOP® anti-condensation layer
In non-insulated or partly insulated buildings, condensation can form on the underside of profiled sheet when warm, humid air meets the colder metal, and the water then drips into the building.
DRIPSTOP® is an absorbent layer bonded to the underside of the sheet in the factory. It works by capillary absorption: it holds the condensed moisture for a while and stops it dripping. When conditions change, for example when the temperature rises or the room is ventilated, the moisture is gradually released back into the air.
It is recommended for buildings without classic thermal insulation or a suitable vapour barrier, such as halls, warehouses, canopies and farm buildings with large temperature differences. It also reduces noise, especially the sound of rain, and is non-combustible and free of harmful chemicals. Properly insulated buildings, or structures with a ventilated layer that prevents condensation, do not need it.
