Resablok is a multi-level, multidirectional scaffolding system, consisting of a set of standard tubular parts assembled and fitted together by means of a rosette-shaped system (4 or 8 holes) providing as a final result a light, but completely rigid structure. This is a patented system holding a Product Certificate for compliance with the UNE – EN 12810-1 and UNE – EN 12810 – 2 Standards. Using the Tricalc (Arktec) software, space calculations for three-dimensional structures can be performed (in terms of resistance and finite elements).
