Round bars as key components for making moulds, dies, jigs and fixtures
Round bars are indispensable in many areas of manufacturing. They serve as a base material for high-precision components and provide a solid foundation for a wide range of applications.
Round bars are primarily used in applications where dimensional stability and dimensional accuracy are crucial. Typical applications include:
- Mould making: Here, round bars are processed into core pins, guide pins or cutting elements. They ensure the highest precision and durability of the moulds.
- Die making: Guide bushes, retainer clips, guide pillars and cutting punches can be made from round bars.
- Machine and jig construction: Round bars serve as the basis for shafts, axes, bolts or bushes used in machines or jigs and fixtures.
- General turning of round parts: From simple axes to complex precision parts – round bars enable the manufacturing of a wide variety of components for a diverse range of industrial applications.
Why choose round bars from Meusburger?
Our round bars are hot rolled or peeled and sawn to the desired dimensions. This guarantees consistent quality and high dimensional accuracy for every application.
Whether for core pin production, precision parts or general round part manufacturing – with our round bars, you can count on reliability and precision that will take your manufacturing to the next level.
Round bars in all varieties and grades of hardness

Material numbers for steel explained simply
Choosing the right material is a key factor for success in mould and die making – yet behind these seemingly cryptic material numbers lies a clear system. In this blog post, we show how material numbers are structured, what their digits mean, and why they are so important in practice.
