Hello,
we are looking for precision reference beams that will stand vertically and support weights up to 2Kg. We would like a flatness spec. of 20mil or less over 6', and low weight => aluminum, fiberglass or carbon fiber might be best. Standard aluminum extrusions, and fiberglas pultrusions, cannot meet the flatness spec. Can anyone suggest a supplier that might meet our needs ?
Thank you,
Declan Hughes
