Rolling Sheet Metal Radius

Recommended inside bend radius for sheet metal parts should be equal to material thickness.

Rolling sheet metal radius.

For steel the factor is 1. In this case the minimum radius equals the respective sheet thickness. 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. Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion.

These parts are rolled from 18ga sheet metal that was perforated and are rolled to an inside radius of 6. If copper has to be bent a factor of 1 5 must be used. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. But for harder materials e g.

We also specialize in sheet metal bending and plate bending with a bending capacity up to 500 tons by 18 feet. Protocase tech tip video. When it comes to curved steel finding the precise measurements is a challenging undertaking. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick.

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. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. Sheet metal rolling is just one of our specialties here at jorgenson metal rolling forming. If the radius used is less than the minimum bending radius the metal can tear at the edges or can spall.

To solve this cmrp provides easy to use measurement calculators. Torn workpieces can then no longer be used. Bend radii minimum bend sizes. Before a metal sheet panel can be bent the minimum bending radius must be determined.

Quick video about bend radius watch more tech tip videos bend radii minimum bend sizes. This value represents the limit at which the material can still be bent without defects. If you re bending 0 020 thick material use a 0 020 radius.
