The study aims to examine the impact of hot-dip galvanizing technology on mechanical properties (Re - yield strength, Rm - ultimate tensile strength and percent elongation - A) of carbon steels HC260LA and DD11 (StW22). These steels are commonly used to manufacture components of building scaffoldings, guardrails, pipes etc. Obtained results showed the effect of galvanization parameters on mechanical properties. The yield stress (Re) increased by 24.49% for HC260LA and by 9.98% for DD11 (StW22). The decrease of the ultimate tensile strength (Rm) was: 2.07%, and 0.29% respectively. Moreover, the average percent elongation (A) dropped comparing to ungalvanized samples for HC260LA steel by 19.96%, and increased for DD11 (StW22) steel by 4.59%. This may be important information for many constructional applications.
