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 plates. It involves installing a material resembling an inverted T-shape on the weight-bearing structure, with the top end supporting an elliptical shape. During panel installation, the panels are overlapped onto this material, and then locked in place using a locking machine.
