Värvitud PPGI GI valmistatud tsingitud katuselehemähised
The hot-rolled steel plate is made of continuous casting slab or blooming slab as raw material, which is heated in a walking furnace, descaled by high-pressure water, and then enters the rough rolling mill. Rolling, after the final rolling, it goes through laminar cooling (computer-controlled cooling rate) and coiling by a coiler to become a straight coil. The head and tail of the straight hair curler are often tongue-shaped and fish-tail-shaped, with poor thickness and width accuracy, and the edges often have defects such as wave shape, folded edge, and tower shape. Selle mähise kaal on raskem ja terasmähise sisemine läbimõõt on 760 mm
