Bars

Bars – Exact. Precise. Versatile.

We supply precision straightened bars with a diameter range from 0.10 mm to 4.00 mm and a length from 1,000 mm to 6,000 mm. Depending on requirements, the tolerances are ±0.001 mm to ±0.02 mm in diameter and ±0.2 mm to ±1.00 mm in length. Our bars demonstrate outstanding straightness, dimensional accuracy and a variety of materials.

Custom-made – down to the last detail: all bars are manufactured exactly to your drawings or technical specifications. We offer solutions for micromechanics, medical technology, precision engineering and industrial applications. Our manufacturing expertise allows us to process over 250 different alloys, including stainless steel, non-ferrous metals, titanium, tungsten and lead-free special alloys.

Delivery forms and packaging: we supply our bars aligned and individually packaged – whether in protective tubes, boxes or special packaging – precisely tailored to your requirements.
