适用范围: This standard lays down the requirements regarding materials, fabrication and finish of metal rolling shutters and rolling grills for normal use.Note —Since the term ' rolling shutters ' is more commonly used, the reference in this standard is mainly to rolling shutters. However, since rolling shutters and rolling grills are similar in design, construction and operation, all references to rolling shutters in this standard shall apply to rolling grills also. A separate clause (see 9) dealing with the special features of rolling grills, as different from rolling shutters, has also been incorporated.
