Rolling Sheet Metal Radius

For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick.

Rolling sheet metal radius.

Before a metal sheet panel can be bent the minimum bending radius must be determined. For steel the factor is 1. Recommended inside bend radius for sheet metal parts should be equal to material thickness. Sheet metal rolling is just one of our specialties here at jorgenson metal rolling forming.

Protocase tech tip video. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. Beams easy way to 44 1 1 m section depth beams hard way to 44 1 1 m section depth beams swept to 44 1 1 m section depth beams cambered to 44 1 1 m section depth square hss to 20 x 20 square hss diagonal to 20 x 20 rectangular hss easy way to 20 x 16. These parts are rolled from 18ga sheet metal that was perforated and are rolled to an inside radius of 6.

Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. But for harder materials e g. When it comes to curved steel finding the precise measurements is a challenging undertaking. In this case the minimum radius equals the respective sheet thickness.

Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion. Quick video about bend radius watch more tech tip videos bend radii minimum bend sizes. Rounding off sharp edges with radius cutters good and accurate rounding of steel constructions according to en 1090 iso 12944 iso 8501 or imo pspc is becoming more and more important in the metal working industry. Torn workpieces can then no longer be used.

To solve this cmrp provides easy to use measurement calculators. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. This value represents the limit at which the material can still be bent without defects. If the radius used is less than the minimum bending radius the metal can tear at the edges or can spall.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Bend radii minimum bend sizes. We also specialize in sheet metal bending and plate bending with a bending capacity up to 500 tons by 18 feet.
