Beschreibung
Zusammenfassung:	The utility model provides a novel metal rolling door which has the advantages of good tightness, little resistance when the metal rolling door is lifted and slides, little abrasion of the metal in a matching position, small noise for vibration, etc. The positive effects are achieved through three novel structural designs which are as following: (1) a door plate bar adopts a tubular structure; (2) a lining bar molded by soft and rigid plastic is arranged in the upper and the lower adjustable buckling positions of adjacent door plate bars; (3) a nylon slide block with a novel structure is adopted.
