Hi there - may seem like a strange request. I need to build some detachable screens to protect the glazing at the front of a property from occasional storm waves. If I do it in stainless framework in box section of 100 x 500 x 5 the panels become too heavy to handle. They won't be sliders, they'll need to be manually lifted into place at times of need. The height is approx 2.8m and I need to cover a width of 6m. If i was doing them in steel the most I could possibly hope to lift would be panels of 500mm wide, but even that would be difficult.
