Product Description

The aluminum spacer bar is used in double glazing units as supportive component. More specific, the spacer bar is the thin aluminum frame which separates the two or three glass panes to improve insulation from heat and sound transmission.



As per different function of bars, spacer bars can be divided into two types: bendable and standard(unbendable) .


Bendable Aluminum Spacer bar

Bendable window spacer bar is back welded and automated manufactured with its mechanical features . Alloy material and special temper ensure the corner are smooth and well formed. Usually, high purity aluminum is applied as raw material to ensure product's quality. 


Standard Aluminum Spacer bar

The utility model relates to a thin wall high-frequency welding spacer.

Standard Aluminum spacer bar is kind of high-frequency welding spacer with thin wall thickness.It has no need to be bent,so we choose special aluminum alloy for better hardness and strength to make up for the lack of strength due to the wall thickness.The leftover of the spacer bar can also be used by connecting with steel straight connectors. Beautiful appearance, reasonable price is an excellent substitute for cold drawing aluminum spacer bar.
