ROCK's aluminum spacers are the first choice for glass insulation due to their continuous production using the latest roll-forming and high frequency induction welding equipment.

To meet the needs of various markets, aluminum spacers are available in various dimensions for insulating glass production.

Aluminum spacers are suitable for cut-and-plug applications with plastic corner connectors and for machine bending with metallic straight connectors.

The thickness of the aluminum materials varies from 0.18 mm for lower thermal conductivity and cost efficiency to 0.35 mm for bendability and strength.

Aluminum spacers are available in different sizes, with a nominal width of 4 mm to 40 mm. The standard length of aluminum spacers is 5 meters, although other lengths are optional upon request.

In addition, if required, ROCK can produce colored spacers in many colors using powder coating technology.
