Just going on - those steels would weigh a ton.

I had a 203x102x26 3.2m long and it weighed 100kgs or there abouts.

I paid about £90 for that delivered and it took a few of us to lift it into place, I bet they weigh a fair bit more than that.

What have the architect specced for it to sit on??? (are the blocks in your garage walls dense blocks or aircrete type blocks?)
