automatic change C Z purlin roll forming machine is used to produce various types of C/Z purlins. It can produce various specifications of C/Z purlins by using the same equipment through automatic and manual simple stepless adjustment. There is no need to change specifications. Replace the forming roller. Do you know how the material width of C/Z steel is calculated?

λ is the feed width, W is the outer dimension of the bottom width, H is the outside height of the waist height, E is the outside dimension of the small edge, & is the thickness of the material, K is the empirical coefficient: when the thickness of the board is 1mm to 2mm, K takes 7 and the board thickness When it is 2mm-3mm, K takes 6. Feed width calculation method: λ=W+H×2+E×2-&×K

Take the non-standard C200×60×20×1.8 as an example: λ=198+58×2+17×2-1.8×7=335
