We use proprietary manufacturing technology to produce tubes with all of the above.
A combination of properties not available from conventional filament wound or prepreg tubes, ideal for;
Inspection Equipment & Standards
Precision Jigs & Fixtures
Optical Machine frames
Rollers for Printing, Paper, Textile and Industrial Machinery
Driveshafts for Cooling Towers, Marine and Industrial Equipment..
The following relates to just one size of tube, hundreds of which are in service around the world.
