Bending Sheet Metal

Bending is the forming of sheet metal by application of force, which exerts pressure on a certain length of material either at a certain point or linear as an evenly distributed weight. This applied... Read more

Brinell Hardness Test

The Swedish engineer Johan August Brinell lived from 1849 to 1925. During his career he researched for alternatives to the resistance test methods that existed until then. His original suggestion was... Read more

Inert Gas

Most metals are characterised by their stability and strength and are therefore a perfect material for structures, which have to withstand extreme loads. These include, among other things, bridges... Read more

Iron Carbon Diagram

Carbon is the most important alloying element in iron. The quantity of carbon contained in the iron is decisive with regard to the hardness of the material and therefore its subsequent usability. At... Read more

Material Numbers

With the introduction of material numbers, a practical system was developed for uniquely defining different materials. A material number consists of 7 digits, which are in turn divided into 5... Read more

Material Types

At Rime different material types are worked. Sheets and plates made of Steel (black sheet/plate) are most frequently used. If sheets and plates are required, which have to withstand wind and weather,... Read more

Metal Sheet Formats

The large variety of sheet and plate formats and properties are found today in steel. A metal sheet or plate is basically relatively thin but has a large area. It is because of this low thickness... Read more

Minimum Bending Radius

Minimum bending radii must be adhered to in order to prevent quality losses caused by stretching and compression. If the bending radius is smaller than this minimum value, cracks form on the outside,... Read more

Press Capacity Tool

Sheet metal bending is one of the most used sheet metalworking services. A lot of press capacity is needed to bend a metal sheet by a bench press. It is necessary to calculate the needed press... Read more

Rockwell hardness testing

In Rockwell hardness testing, the hardness of a material is determined by pressing an indenter against the material be tested with a predefined force. The hardness of the material can then be... Read more

Sheet Metal

Sheet metal has been much sought-after for thousands of years. In production terms it is a semi-finished product, which is processed to produce a finished product by undergoing further machining... Read more

Standard Specifications

There are many different standard specifications that are applicable for different kinds of sheet metal. Here is a list of important standards like relevant EN standards for metal sheets and plates... Read more

Steel Alloy Elements

Over the centuries, very many different alloys have been developed, which satisfy all kinds of different requirements. Metallurgy is a complex science, and today precise statements can be made about... Read more

Steel Grades

Today, several hundred different steel grades exist, which differ according to the many different compositions of their alloy elements. Depending on the planned place of use, steel grades with... Read more


The stress-strain curve can be used to read off the structural loadability of materials. For many materials, including metals, their loading bearing capability (loadability) is one of the most... Read more


The general term wear can also be understood as consumption and is the continuing loss of material from the surface of a solid body. The progressive consumption is caused by grinding, rolling,... Read more

Weight calculator

Steel, aluminium and stainless steel are the most used construction materials. A precise weight calculation is extremely important for big metal constructions, in the the transport sector and for... Read more
