A very regular job of ours is fabricating staircases - these are usually supply-only which is always a good earner. We've a batch of 20 to do (We do batches of anywhere between 10 and 100 usually)
4 blokes have bashed out 20 of them between 7am and 2pm today. Stringers are laser cut out of 10mm plate and me and another lad sheared and folded the treads earlier in the week. We use jigs to set the treads on the stringers which saves a lot of marking out.
Not our design this time - the treads are 1330 long and only out of 3mm sheet. Surprisingly solid when folded and all welded together.
Only fire escape stairs, and to receive a screed infill which hides all the welds, so no need for a great deal of cleaning up after welding.
Horrible trying to weld 3mm to 10mm and not swell the front of the 3mm. Welded using Speedpulse which lets us keep the heat down but not end up with a spattery mess which you'd otherwise get by coming out of spray transfer on a transformer MIG.
