Production process
The production process is similar for all three kinds of roof construction. It can be divided into the following stages:
Design
On the basis of the structural design of a building we draw up a working design of the roof framing. Depending on the type of designed roof, our designer prepares a plan for the roof truss, roof panel or unassambled framing.

Production
The designed roof elements are cut to size using the Randek's cut saw.

Next the cut-to-size elements are impregnated by dipping them into approved salt preservatives according to legally binding regulations. All components of the roof truss are laid on magnetically stabilized assembly tables and joined with suitable metal nail plates using a hydraulic press.

Transport
Roof framing is transported in trucks with a 20 tonne maximum load weight. In practice, loading is determined by the dimensions of roof components rather than their weight. Load capacity can be reduced, especially in the case of roof panels and truss girders.
Assembly
The roof assembly is preceded by the following preparatory work: the wall plates are laid out in previously appointed places, on top of the insulation layer. Next the crane transfers roof elements from trucks to the installation locations and they are fixed into place with systemic fasteners.

All the types of prefabricated roof constructions allow for on-site working time reduction, production independent of weather conditions and improving the quality of constructed roofs.
