Long Length Tooling Steel Stock

[spggodd]

Hi,

Does anyone know where I can purchase a precision ground flat bar with dimensions of:

Width = 24mm
Height = >24mm
Length = 1.5 - 2m

The bar is being used for the alignment of two large frames and needs to be precision ground.

Can I get this as a standard tooling item or will this need to be custom made?
If so can you suggest a supplier. (UK based if possible!).

Thanks
Steve
