Berylco rod  and bar products availability


In addition to a variety of rod dimensions, NGK Berylco can also deliver some profile rods (square, rectangle, hexagonal, plane) cold draw or hot worked and some out of limits diameters.

The regular Berylco rods are produced appointed and chamfered

Rod scan be delivered following rectification

Special tolerances – The Berylco rods and wires can be delivered with narrow tolerances (h6, h5, h7) achieved by rectification or special process.
