Bending 18 Gauge Sheet Metal

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.

Bending 18 gauge sheet metal. Showing how i bend steel plate without using a brake. 22 gauge 0 030 0 76 mm. For example in one gauge system 18 gauge steel. Cut the section of metal out or otherwise prepare the metal to be bent by removing any burrs or sharp edges.

Determine the angle at which you want to brake the metal and mark it on the protractor. How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools. It is well built and easy operating. π 180 x b x ir k x mt bend allowance ba where b is the angle complementary to your desired bend angle 1 to 180 degrees mt is the thickness of the material ir is the inside radius and k is the k factor.

The material thickness will be measured in decimal form not by the gauge number. Bends metal up to 18 in. You will use the protractor to gauge the brake as you bend the metal little by little. You can find your bend allowance with the following formula.

Category thickness minimum bend bend radius. Makes bends to 90º. This 18 inch mini sheet metal bending brake is an excellent choice for bending with less width and high capacity. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.

It has the same cutting gauge capacity compared to 30 and 40 inch bending brake. How to bend sheet metal without a brake. There are several different gauge systems used today with specific gauge designations used for specific metal types. Handles material as thick as 16 gauge.

The gauge number 18 holds no relevance to the actual measurements. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Easily clamps or mounts to workbench.
