Part 3: Always comply with the fixing-specific permissible loads

Two factors must be taken into consideration in specifying the loads with effects on the fixing installation: amount of load and load direction. In addition to the weight of the object or structure to be fixed, loads are also always a question of the directions of the load caused by the weight and the type of the load. The load on the installation can refer to traction force (N), shear force (V) or compression force (N). Usually, the combined load of these forces affects the fixing. The unit of load is kilonewton kN, with 1 kN corresponding to a mass of approximately 100 kg.Kuormitustyypit

The permissible load of fixtures must absolutely be complied with to ensure the safety of the installation. The permissible values include a fixing-specific safety margin. The permissible traction load and, where we have considered it necessary, the permissible shear load have been specified for all of our fixings. In connection with the loads, it is mentioned if the values are based on a European Technical Assessment (ETA) for a specific fixing base and installation.
