Hi Sales,rnrnWe are looking at installing some spiral lockseam tubing as venting for composting tanks. rnrnI am interested spiral ducting 305OD x 0.6mm thick in 304 stainless. What is your minimum order quantity and how much would it cost per metre. We would need a quote for 6m of spiral ducting cut into 3m Lengths if possible. rnrnKind regardsrn
