Slitting cutting
avoid defect of flame cutting
use slitting cutting avoid most of the defect of traditional flame cutting, such as edge defect, edge unevenness, unsmooth,crack,roughness, dregs,crack etc






Laser cutting
greatly improves the cutting accuracy and quality,also will greatly avoid the deformation of some components and the generation of welding porosity






3D H beam drilling machine
adopts 3D H beam driling machine, which can realize H beam web & flange drilling in three directions at once,this strongly improve the precision of hole making
