Abstract As a product with high added value, the full hard(FH) strip is mainly used for building and its shape control is a difficult problem in hotdip galvanizing. By mechanical test of the steel strip and simulation of strip deformation in tension leveling using finite element method, characteristic features of the strip were obtained, such as; high yield stress, high yield ratio and low plastic elongation as the basic reason of difficulty in tension leveling and shape control. Based on simulation results and debugging of process parameters on site, full set of technical measures including optimum tension leveling parameters for FH product were put forward, and good effect of strip shape control was obtained.Varieties of color coated hard full strip are steady produced.
