Rain profiles at the rear portal – aluminium water guidance for dry cargo in the truck body
Rain profiles are the slim, pressed aluminium profiles installed at the rear portal of the truck body above the rear doors. They guide rainwater and splash water laterally away from the door area and prevent moisture from entering the box body when the doors are opened. In this category you will find rain profiles for common truck bodies, corner closures and matching fastening elements, as well as additions to the sealing system at the rear portal. At SULEJ Ladebordwand, decades of experience in maintenance and repair of commercial vehicles flow directly into the selection of these components – for reliable drainage of precipitation water, a permanently dry cargo area and high-quality protection of the transported goods.
Function and area of application on the truck body
Rain profiles are installed directly above the rear portal on the truck body. During travel and during loading and unloading, precipitation water hits the roof, runs along it and collects at the rear edge of the body. Without a defined rain profile, this water would run directly over the door and sealing edge into the interior as soon as the rear doors are opened. The aluminium profile catches the water, guides it laterally to the body corners and drips it off in a controlled manner. Rain profiles thus complement the sealing system at the rear portal and protect sensitive goods such as cardboard packaging, food or electronics against moisture and damage.
Designs, profiles and materials
Rain profiles are mostly manufactured from extruded aluminium. Aluminium is light, dimensionally stable, corrosion-resistant and can be precisely adapted to the lines of the truck body. Common are L-shaped drip edges, angled water drainage profiles and multi-shell versions with integrated outlets at the outer sides.
The surfaces are generally anodised, powder-coated or clear-lacquered to permanently protect the material against UV radiation, road salt and weather. Corner connectors, end caps and angled transition profiles ensure that water is guided cleanly away from the rear portal and does not enter open body cavities. Rain profiles are usually fastened with stainless steel screws, rivets or a combination of gluing and screwing, depending on the construction of the respective box body.
