I ordered the flat bar from my mates’ engineering shop, had it cut and the edges lenished.

On site we remeasured the lengths and primed the steel with an oxide undercoat. Steel posts were cut to size and plated top and bottom. The existing beam was plated in stages and then welded. Where the existing beam ended we laminated two lengths of pine the same size and used it as a packer. This was to prevent the steel from buckling or distorting when we were tightening up the bolts and when the building load would be applied. The holes were marked, drilled and bolted. The post were bolted and welded to the steel plates.

Finally we re painted the areas where I welded.
