Product Overview

Curtain Wall Aluminum Profiles are structural aluminum extrusion components used in curtain wall façade systems for commercial and high-rise buildings. They form the primary framing structure that supports glass panels, insulated glazing units (IGUs), pressure plates, and external cladding systems.

FAQ

Q: What is the lead time for curtain wall aluminum extrusion profiles?

A: Typically depends on die development and order volume. New tooling requires mold approval before production; repeat curtain wall aluminum profiles are faster due to existing extrusion dies.

Q: Can you produce custom aluminum extrusion profiles for curtain wall systems?

A: Yes. Custom curtain wall aluminum profiles are developed from architectural drawings, including mullions/transoms and façade system structural requirements.

Q: Are your profiles compatible with international curtain wall façade systems?

A: Yes. Profiles are designed for compatibility with mainstream curtain wall façade systems, including thermal break and structural glazing applications.

Q: Which surface finish is suitable for harsh environments?

A: PVDF coating is recommended for curtain wall aluminum profiles in coastal, high UV, or extreme climates due to superior weather and corrosion resistance.

Q: How is dimensional accuracy controlled for façade projects?

A: Controlled aluminum extrusion with in-process inspection and final dimensional verification ensures stability for curtain wall system assembly.
