Inquiry (采购产品): Aluminum rectangular tube I'm looking for 3" x 4" rectangular aluminum extruded tube (Square or round coner is OK) with a 1/4" wall, 3/16" wall would be OK. I would like 6061 but will settle for 6063. My initial buy will be only about 20 feet for prototype but will increase to about 100 feet per month. Can you help? Thx: Gene Hamilton: Quadra Mfg.
