Rolling Sheet Metal Radius

We also specialize in sheet metal bending and plate bending with a bending capacity up to 500 tons by 18 feet.

Rolling sheet metal radius.

These parts are rolled from 18ga sheet metal that was perforated and are rolled to an inside radius of 6. 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. To solve this cmrp provides easy to use measurement calculators.

If the radius used is less than the minimum bending radius the metal can tear at the edges or can spall. But for harder materials e g. Quick video about bend radius watch more tech tip videos bend radii minimum bend sizes. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2.

Torn workpieces can then no longer be used. For steel the factor is 1. 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. If you re bending 0 020 thick material use a 0 020 radius.

In this case the minimum radius equals the respective sheet thickness. Before a metal sheet panel can be bent the minimum bending radius must be determined. 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. This value represents the limit at which the material can still be bent without defects.

Protocase tech tip video. Recommended inside bend radius for sheet metal parts should be equal to material thickness. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. When it comes to curved steel finding the precise measurements is a challenging undertaking.

Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. Bend radii minimum bend sizes. Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion.
