PRESS BRAKE TONNAGE CALCULATIONS FOR SPECIAL SHAPES- printable PDF  

 The Press Brake Bending Chart gives you the approximate tonnage to form a 90 degree bend with mild steel. 

 An important factor when press brake forming is the width of the flange.  The tonnage charts provide will provide the tonnage to bend the form, but you also must consider the tonnage required to lift the sheet.   Consider the wieght of the steel plate - check out the metal weight formula page on this website.  When you have trouble bending a large plate on a press brake and think it may be the press brake problem, take a close look at the actual tonnage required.
