Inquiry (采购产品): general info I have a thin wall square metal tube 2"x3"x3feet. I want to fill it with a material that will bind the sides together and add structural rigidity. I want it to be quite stiff and strong. I was considering high density Urethane foam but I have no way of pouring the foam into the tube fast enough. I will need to pump the material into my tube through several holes drilled into its top. I was thinking of using a desposiable hand pump or turkey baster or poaring it down a funnel with a hose attached to its tip. Something in a spray can would be the best. It does not need to be a foam just easy to place and strong. I am Not an engineer just a do it yourself shop owner with a problem. Do you have a product that you can recommend. Any help will be greatly appreciated. Thanks, Richard Stephen **** Hidden Message ***** Richard Stephen 15 12th.
