For the building and construction market, your extrusion projects take on added value when they are thermally efficient.


At Astro Shapes, we utilize our production facilities and our expertise to properly fill and debridge or create a mechanical bond between polyurethane and metal.

Options are as follows:

  • The Azon two component polyurethane system is formulated to meet the most demanding tensile, impact elongation, UV and environmental conditions. The polyurethane is poured into a thermal break channel and ‘’set’’ in line and debridged.

  • The Polyamide Strips System is a process of mechanically locking polyamide with two or more extrusions. This system allows the flexibility of producing two-tone aluminum extrusions with high performance paint on the exterior while utilizing standard paint on the interior. The system also enhances our ability to redesign complex extrusions and expand our circle size.

  • Our system provides a superior product to more conventional systems with regards to straightness, twist, and shear strength.

  • Astro Shapes can also perform the Azo-Brader® technique on your extrusions, creating a mechanical bond between the polyurethane and the metal. Beneficial to all thermal applications, this process is highly recommended for metal in a mill finish or anodized state.
