Introduction

High-Performance Structural Framework

Our aluminum mullion and transom profiles are manufactured from premium 6063-T5 or T6 alloys to provide the essential structural framework for glass curtain walls. These profiles are designed to accommodate various glazing thicknesses and integrate seamlessly with thermal break technologies for superior energy efficiency.

Benefits

Why Choose APEX Curtain Wall Profiles

  • Superior Structural Load Bearing Capacity

    Engineered with optimized wall thicknesses to withstand significant wind pressure and dead loads in high-rise applications.

  • Advanced Thermal Break Integration

    Designed to house polyamide thermal strips that effectively minimize heat transfer and prevent condensation.

  • Precision Extrusion for Seamless Assembly

    Tight manufacturing tolerances ensure perfect alignment between vertical mullions and horizontal transoms for water-tight joints.

  • Exceptional Corrosion and Weather Resistance

    Available with high-grade PVDF or powder coatings that protect the substrate against UV radiation and coastal salinity.

Standard

Customization and Material Standards

We offer a wide range of profile geometries to support stick-built, semi-unitized, and fully unitized curtain wall configurations. Standard depths range from 120mm to 250mm, with custom die-cutting available for unique architectural requirements.

All profiles meet international standards including ASTM and GB/T. Finish options include clear or color anodizing, electrophoresis, and AkzoNobel or PPG certified powder coatings for long-term aesthetic durability.

FAQS

Frequently Asked Questions

Shaped aluminum panels are commonly used in architectural projects requiring customized facade geometry. Below are key questions.

What aluminum alloys are used for these profiles?
We primarily use 6063-T5 for standard applications and 6061-T6 for projects requiring higher structural tensile strength.
Can these profiles support triple-pane glazing?
Yes, our transom designs can be customized with various pocket widths to accommodate double or triple-glazed units up to 50mm thick.
Do you provide structural calculation reports?
We provide technical data sheets and can assist with preliminary structural analysis based on your project's wind load requirements.
Are the profiles compatible with hidden frame systems?
Absolutely. We offer specific profile designs for exposed cap, semi-hidden, and fully hidden frame curtain wall systems.
What is the maximum length available for mullions?
Standard extrusion lengths are 5.8m or 6.0m to fit shipping containers, but we can extrude up to 12m for specialized local projects.
