Inquiry (采购产品): box Tube I am looking for box tubing 1/4" thick 4" x 6" OD; 4 lengths 11' long for a salt water environment. Also, I would like to have channel 1/4" thick x 48" long that would fit over the top of the rectangle tube. That would be 4" + ID wide by 3 " deep -- 8 pcs. I want to hinge the 48" pcs to each top end of the 11' pcs. I'd consider anything you have to make this work. Thanks Carl Smith I have had great success with aluminum over stainless in salt environment **** Hidden Message ***** Carl Smith 34104 Company: Mac Holdings Corp E-mail: macholdings@earthlink.net **** Hidden Message ***** macholdings@earthlink.net
