    Cutting Disassembling Steel Grate

    Long time reader, Great people here!

    Thanks in advance for any help you can give me

    I have a 48 x 48 steel bar grate that has 2 sides of 1/4 bars with 3/16 bar sandwiched between to join them

    I'm trying to remove the bars from one side and reorient them on the other side

    The goal is to make the openings smaller and lighten it a bit

    I've tried a cutting wheel, recip saw, and plasma torch. All of which have their upside and down sides in time and consumables

    I realize that this may just be the nature of the beast, but I just feel like I'm missing something obvious

    If anyone has any experience with grates, maybe you could give me some suggestions

    Thanks!

    Buy more material (1/4" rod is cheap), cut more bars and weld them on the other side.

    On second thought, just make a new one - way faster

    That's what I thought, just didn't want to overlook something obvious

    I just keep thinking about the wire pipe cutters but I've never seen one done in a portable

    Something like a portable band saw

    Anyway, thanks again to all

    The 1/4" bars would be "easy" to snip off with some large bolt cutters, and then you'd just be left with grinding down the stubs where they're welded to the main body. The problem is that you're then left with a bunch of short bits that aren't really reusable to fill in the other side. Of course, buying some 1/4" round bar in long pieces is cheap and easy, so it's not like you absolutely have to use the cut-offs to do the filling in.

    What will be its use. It it must be used then i would use a thin cutoff wheel. Cut vee notch at the weld. Seem like as much work as removing them in pieces.

    It has not been my experience that making grating is easy. Fixturing, spacing, checking , rechecking, bending distorted bars, then discovering you were 1/8 inch off and the last bar shows the difference.

    I have several of these, so at the moment I am making a equipment storage cart and shelves

    I also wanted to make a plasma cutting table (although the powder coating burning off might be a an issue with that)

    Cutting off the bars around the perimeter is fairly easy

    That should give me enough to make add to the grid, for the rest I'm just going to cut them off to save weight

    I am going to try the V Cuts because that might actually help lining them up when rewelding

    I had an old stick welder that I donated to a friend of a friend. I'm kicking myself now because it had an attachment for "fusing/melting" bars together (I forget what they call that process)

    That would have been helpful DOH!
