Corrugated steel tiles are specifically designed 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 profile resembling an inverted T-shape on the weight-bearing structure, with the top of the profile supporting an oval shape. During panel installation, the panels are overlapped onto this profile, and then secured using a locking machine to咬合 the two sheets onto the profile.
