    Hi,

    Quick question. Is it possible to screw your frame together instead of welding the frame?

    If not why not?

    Thanks.

    The problem with screwing metal parts together is that it almost always tends to loosen up after a while and will not give you the stability you need that is something you want to avoid with your frame ..Welding the frame will also be more stable and give you more strength...screws is defiantly not recommended for this application…

    Its amazing how the salt will rust a metal stand, thats why it is important to paint the stand in thick hammerite

    IMO, I think it will be a bit more complicated using screws instead of welding. Mainly because you just have to weld the structure and paint over it. Using screws you gotta consider galvanic corrosion as well. There are ways around this but if you can weld, then I say go for it. Personally, I'm really bad with welding, so I'm actually planning on building an aluminium rack for my lighting unit using extruded tubing and some bolts.

    When you say screws, do you mean bolts?
    The latter would be fine if sized correctly, galvanised, and nyloc nuts used.

    Thanks guys. Busy moving my tank so I need to make a new stand and was just thinking whether "bolts" not "screws" would be better. I can weld so I guess I should just stop been lazy and weld it all. My current stand is welded but was not painted very well which is why I want to build a new one.

    Care to elaborate why you think bolts are not strong enough?
    How do you think many sky scrapers are put together, massive bridges etc.

    Only reason to weld a frame together is because its cheaper and quicker, not necessarily stronger.
