The dimensions for structure is 1198mm x 2400 mm x 51 mm (In top view thesheet metal have 12 mm thickness)

I simulate the structure from top of mechanism for a man with 250 Kg which stayon. (2500 N)I use sheet metal with 12 mm thickness, we use only cut on laser and bend noother structure welded.

THICKNESS = 12 mm===============

12 mm deformation ( 1198 mm x 2400 mm x 51 mm envelope dimensions ofstructure)

We can put a plate in the middle only to reduce the deformation)

4 mm deformation for 12 mm thickness sheet metal 1198 mm x 1175 mm x 51mm

I change the space between the cuts to be 9 mm x 9mm.The general dimensions 1198 mm x 1175 mm x 51 mm

I use sheet metal with 8 mm thickness , we use only cut on laser and bend notother structure welded.
