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.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Sheet metal rolling is just one of our specialties here at jorgenson metal rolling forming. In this case the minimum radius equals the respective sheet thickness. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material.

Bend radii minimum bend sizes. Protocase tech tip video. We also specialize in sheet metal bending and plate bending with a bending capacity up to 500 tons by 18 feet. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend.

Torn workpieces can then no longer be used. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. If copper has to be bent a factor of 1 5 must be used.

But for harder materials e g. 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. If you re bending 0 020 thick material use a 0 020 radius. 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.

Recommended inside bend radius for sheet metal parts should be equal to material thickness. For steel the factor is 1. These parts are rolled from 18ga sheet metal that was perforated and are rolled to an inside radius of 6. When it comes to curved steel finding the precise measurements is a challenging undertaking.

To solve this cmrp provides easy to use measurement calculators. This value represents the limit at which the material can still be bent without defects. Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion.
