Flat Bars

Flat bars, which have a wide range of uses, are manufactured using hot or cold rolled raw materials in different sizes and in S235JR (ST37), S275JR (ST44) and S355JR (ST52) qualities according to their width and thickness.

Flat bars, which are needed in many areas of manufacturing and are an important building material, are named in two separate categories as cold or hot surface according to surface types. Cold surface flat bars are generally preferred in production processes that require surface precision, and hot and cold flat bars can be diversified according to raw material qualities in terms of flexibility and strength.

Generally, 6 meters of hot flat bars and 3-4 or 6 meters of cold flat bars are manufactured, and some sizes of flat bars can be manufactured in different lengths.
