Prices are approximate per metre, based on a standard modulus laminate with approximately 30% hoop strength and manufacturing a tube to the full length of the tooling. Shorter lengths are available but may incur a higher per-metre price.
Please note that there is a minimum order value of NZ $400 per export shipment.
Price will depend on laminate thickness and carbon fiber modulus or fiber type required. Price calculators are provided on some pages. If price information is not available please enquire about a tube to suit your specifications.
