The system can be used for the construction of good-looking footbridges and bridges, for various types of roof structures, pylon constructions, sports stadiums and similar buildings. However, the system is also used in interiors, such as airport halls, car showrooms, shopping centres or various representative spaces, where a high aesthetic and architectural effect of the construction work is required. The PROTAH system is popular for its simplicity, modern aesthetic appearance and easy installation.
The tie-rods are offered in two strength series - PROTAH S355 and PROTAH S460. The system allows tie-rod length rectification depending on the type used and the choice of additional parts. The tie-rods consist of standard parts, but their use can be extended by appropriate use of additional or atypical elements.
The tie-rods are designed and tested according to the standard ČSN EN 1993-1-11 for the effects of static and dynamic loading, and the production is governed by the requirements of the standard ČSN EN 1090 (Certificate of conformity of production control according to ČSN ISO 1090-1:2009+A1:2011). The tie-rods are designed to meet the requirements of the TKP 19A, TKP 19B and TKP 20 regulations of the Czech Directorate for National Roads and Motorways.
