woodward007 Posted July 1, 2007 Share Posted July 1, 2007 Hi All Can any of you experts help me with your knowledge. What I need to know is: >> What is stronger for load bearing-- a standard square cross sectional aluminium tube extrusion or a square cross sectional aluminium tube extrusion WITH grooves/channels on all 4 sides-- eg: like www.aluframesystems.co.uk (See URL below): http://www.aluframesystems.co.uk/ALUFRAME_...OME/IMAG012.JPG Its the type of tubes used for fishing box frames/display stands for sliding clips down the channels/grooves. So do the channels/grooves make the square tube distinctively stronger for load bearing (Standing On) or are they just the same as standard square tube steel? Any help would be greatly appreciated Many ThanksChris Link to comment Share on other sites More sharing options...
Chris Beesley Posted July 1, 2007 Share Posted July 1, 2007 It will depend on the wall thickness, overall dimensions and also grade of aluminium/steel. Also what are you using it for...? Link to comment Share on other sites More sharing options...
Brian Posted July 2, 2007 Share Posted July 2, 2007 If the manufacturer has designed the tube for structural use then they will be able to provide you with the basic geometric properties of the section to allow you to calculate the strength.
