What is sheet metal bending
Sheet metal bending is a mechanical process that enables sheet metal to be permanently deformed along a straight line, creating angles, bends and three-dimensional geometries.
It is one of the most common processes in the light and medium-light metalworking sector, ideal for producing functional and structural components.
With our CNC press brakes, we carry out high-precision bending on steel, stainless steel, aluminium and special alloys, ensuring maximum repeatability even on medium to large batches.

FAQ - Frequently Asked Questions
The main techniques include manual bending, bending using press brakes, roll bending and bending using CNC panel benders. Each method is chosen based on the type of sheet metal, thickness, bending radius and required precision.
Sheet metal can be bent by means of roll bending, manual bending or using press brakes. The method depends on the thickness of the material and the desired bending radius. Specific machines such as panel benders are used for precise and complex bends.
The bend is calculated based on the length of the workpiece, the thickness of the sheet metal and the bending radius. It is important to consider the so-called “developed length” which accounts for deformation during bending to ensure precise dimensions in the final product.
The minimum radius depends on the material and the thickness of the sheet metal. Generally, the minimum radius for thin steels can be equal to the thickness of the sheet metal, whilst for thicker or less ductile materials, larger radii are used to prevent breakage or cracks.
The minimum bend length is determined by the machine’s capacity and the type of bend. Generally, a minimum length is set to allow the material to bend without unwanted deformation, usually around a few centimetres depending on the machinery used.
