highly extending bellow covers black or yellow colour for protecting precision transmission parts
Structure .
A: Flange :
Use proper thickness of plate to fix at both sides or the protective curtain or punched stiffener , and the other side should be fixed at the guide way .
Normally a SPCC sheet metal is applied . upon customer's request , any shape , thickness , other metal or mounting method are available.

a single side with yellow or white color is available . the protective curtain
and stiffener are welded securely without sewing lines or holes . it features
excellent water-resistance and oil-resistance .the material thickness of the protective

doe fast moving speed ,vertical movement or large-scale protective curtain.
the additional restricted belt is fitted for the protective curtain used in a closed
confined space for extending the service life of protective curtain .
