2 sizes of round duct (100mm and 76mm) and 1 size of flat duct (72/21 for 6-4 PT tendon) shall be produced for quick production check. For each duct type we need 8 pcs. with a sample length of 1.5m. Apart from the duct we also need the couplers for the component tests.
Be sure that we clean properly the extruders before start with new color
Best regards,
David
