The nowadays the using of S235 J2 and S355 J2 steel grades in civil engineering to design structures elements of cranes, bridges, building structures or simple engineering parts allows material and economical savings meeting the strict construction requirements. The aim of this contribution was to determine the mechanical, fatigue and strength properties of the old steel from steel truss crane runway in VĂtkovice Company. The second task was the comparison of obtain data from old steel with properties of standard used S235 and mild steel S355 and to make recommendations based on the results which steel grade can replace existing damaged elements made from old steel.
