Corrugated steel tiles are used for roofing, featuring a high corrugation height. The vertical locking edge is an installation method for metal panels, commonly used for titanium-zinc plates and aluminum-magnesium-manganese panels. It involves installing a profile resembling an inverted T-shape on the weight-bearing structure, with the top of the profile supporting an elliptical shape. When installing the panels, they are overlapped onto this profile, and then secured in place using a locking machine,咬合 in the profile.
