Corrugated web beams
A corrugated web girder is the name given to girders for wide-span roof and ceiling structures, the solid upper and lower chords of which are connected to one another or kept at a distance by a lightweight web made of plywood or sheet steel . In order to avoid bulging of the thin web, it is laid in a wave shape.
Corrugated web beams made of steel
Corrugated web girders are welded sheet metal girders with which similar load capacities and spans can be achieved as with lattice girders . The undulating course of the web ensures that no failure due to lateral deflection of the web ( kinks or bulges ) occurs before the plastic limit load of the web is reached.
Corrugated web beams made of wood
Wooden belt girders with wave-shaped glued-in plywood bars in I-shape or box-shaped with parallel wood belts up to a height of 80 cm.
Similar wide-span roof and ceiling constructions made of wood can be made with Kielsteg wooden construction elements or the trapezoidal web element.
