Another tricky bit of cutting with the angle grinder came next.
After the two corner posts were removed (previous post) I needed to cut into the thick steel boxes on the ceiling that form the 8 corners of every container. This was so that the steel "C" beams could sit flush with and support the top rails.
It took many hours and many disks to cut through, taking small chunks out at a time. The steel was 12-15mm thick in parts.
It's not pretty but it did the job!
Then it was time to put up the 1st beam.
Whilst I was doing that, outside Paul planted a dozen rhubarb plants that he had separated from his own garden, as well as mint (after using some pier tube offcuts to form a barrier so their roots don't spread like weeds)
