Stainless steel flat bars look not like a challenge for most steel fabrication related people. However, in some particular applications, the flatness, the straightness, the perpendicularity, surface quality，one or all of these four factors are taken as the very critical considerations.
Here below are the steps how we produce flat stainless steel bars，and every step is done with advanced machines and strictly quality checked to ensure good quality.
1, Grinding，oil abrasive grinding or dry grinding can be chosen on whole width of the coil
2, Slitting, slit the coil into needed strips
3, Prime flattening
4, Straightening
5, Flattening
6, Trimming and Deburring
7, Transversal cutting to needed length
Here below are the main machines we use to produce high quality flat bar:
Slitting machine with following capacity:
Thickness: 2.0-14.0mm
Width: 20-2050mm with tolerance +/- 0.1mm
Weight：Max. 35 tons
Transversal cutting line with following capacity:
Thickness：2.0-14.0mm
Width: 20-200mm
Length:600-12000mm
Flattening and grinding line, capacity:
Thickness:2.0-14.0mm
Width: 20-200mm
Length: 600-12000mm
