MOLITEC STEEL has been handling heat-treated steel strips for half a century and created HIGH-BENT and big-breadth heat-treated steel strips with technologies developed after years of study, and have been making many contributions to all the industries with its world’s top brand products.
HARENED & TEMPERED STEEL STRIPS
MOLITEC STEEL processes carefully selected materials such as cold-rolled special steel strips, stainless steel strips, etc. by continuous heat treatment, etc. and produces heat-treated steel strips suited for various applications under the stringent quality control system. In particular, big-breadth heat-treated steel strips 400 mm (16″) wider achieve the stable profile with our original techniques and enjoy great popularity among many users.
