I have installed a good deal of traditional Dexion shelving in the workshop. Even with the screws securely tightened and with a lightweight load, it was still necessary to install cross-bracing to avoid that 'parallelogram effect'. Although such bracing was made by Dexion specifically for that purpose, I had none, so I used lengths of softwood, suitably painted.
The 'golden rule' for fitting bracing, of course, is always to aim at making triangles.
