Yup, two people can move it with no problem. One of them will be on a fork lift, though. :laughing: With out having the specs to go by I'd guess it weighs about 450 lbs.
That piece of channel will stay with the stair.
This stair is a replacement for an existing, but very rusty, stair. The channel that goes under the landing, and the channel at the other end of the landing will get welded to the existing channel from the old stair, that goes through the masonry into the structural steel, after it's removed. I've left the grip strut planks on the landing loose, and just tacked the piece of channel that goes against the building so they can be removed for installation.
I know this explanation is screwy but I don't know how to explain it better unless I draw it, which I will if you'd like.
