ZST sprinkler head executes national standard structure of GB5135.1-2003 Part 1: Sprinkler Head of Sprinkler System.
ZST glass ball sprinkler head is assembled from glass ball, copper alloy gold frame and seal. Spray head frame is precision forged by copper alloy with high strength, strong corrosion resistance, polishing chromium plating in surface. And a variety of specifications for users to choose; the glass ball (temperature sensing element) and sealing gasket are made of high quality imported material which is resistant to aging and corrosion. The glass ball has high strength, reliable action and fast reaction speed.
