Fabricating a long flashing can reduce the number of joints on the building. However, it must be delivered without permanent deformation. The thin profile requires support and proper surface protection. When planning an order, it is worth checking access, the unloading area and how the parts will be carried in. Ridge caps, barge flashings and gutter aprons may be the same length and yet behave differently when handled. Before confirming production, establish whether the vehicle can safely reach the unloading point. Check the available space and the route for carrying the elements. A long profile should not be bent to fit between obstacles. Such deformation may remain visible after installation.

In a livestock building, the entire internal surface must be assessed. This includes the cladding, joints, fasteners and flashings. Glass-fibre-reinforced laminate can be part of a suitable solution. However, it does not mean resistance to every ammonia concentration or to any cleaning agent used during washing. Gather information on the humidity, temperature and usage of the room. Ventilation and the presence of aggressive substances are also important. The term ‘agricultural building’ alone covers very different conditions. A dry store performs differently from a cowshed, and differently again from a room that is regularly disinfected.
