Architectural Cladding Aluminium Profile | Exposed & Concealed Curtain Wall Mullion

Different from ordinary door and window profiles, these curtain wall aluminium sections feature thickened wall structure, high wind pressure resistance and strict dimensional tolerance. Fully compatible with standard glass panels, EPDM seals and assembly hardware, they support fast standardized installation and serve as core structural components for modern building facade renovation and new construction.

• 6063-T5 (Standard Universal Grade)

As the mainstream material for over 90% of conventional curtain wall projects, 6063-T5 features excellent dimensional stability, fine surface finish and good ductility. It is not prone to deformation during processing and assembly, perfectly fitting all 100/130 series exposed and concealed frame curtain wall systems. With stable coating and anti-aging performance, it is the most cost-effective option for regular mid-rise and high-rise facade engineering.

• 6063-T6 (High-Strength Upgrade Grade)

With higher tensile strength and hardness than 6063-T5, 6063-T6 is tailored for super high-rise buildings, coastal strong-wind areas and large-span curtain wall structures, effectively resisting extreme wind pressure and temperature changes to enhance overall facade safety.

• 6061-T6 (Heavy-Duty Structural Grade)

This high-performance structural alloy boasts ultra-high load-bearing and impact resistance, suitable for special heavy-load curtain walls, large-span landmark facades and extreme weather engineering scenarios that require maximum structural stability.

Three Core Curtain Wall Section Specifications

• 100*65 Exposed Frame Curtain Wall Section (Economical Standard Type)

Featuring 100mm mullion width, 65mm transom height and 2.0–2.5mm standard wall thickness, this exposed frame section is a cost-effective solution for mid-rise commercial buildings. It presents neat three-dimensional metal lines on building facades, with mature assembly technology and stable structure. It greatly shortens construction cycles and controls project costs, widely used in ordinary office buildings, community commercial facilities and public construction projects.

• 130*65 Exposed Frame Curtain Wall Section (Reinforced Stable Type)

Upgraded with a 130mm widened mullion and 2.5–3.0mm thickened wall, this reinforced section delivers stronger torsion resistance and wind pressure resistance than the 100*65 model. It supports larger glass span sizes, reduces frame segmentation, and creates a concise and grand facade effect. Ideal for high-rise office buildings, large commercial complexes and urban key projects, it maintains stable waterproof, airtight and structural performance in complex outdoor environments.

• 130*65 Concealed Frame Curtain Wall Section (High-End Decorative Type)

Adopting the same 130*65 reinforced main structure with hidden assembly design, this high-end section conceals all aluminium frames behind glass panels, forming a seamless, minimalist transparent facade. Equipped with integrated reinforced extrusion and precision locking grooves, it ensures tight glass fitting and excellent weather tightness. It is the preferred choice for high-end hotels, exhibition centers, art venues and urban super high-rise landmark buildings pursuing modern architectural aesthetics.

Surface Treatment & Weather Resistance

All 100/130 series curtain wall aluminium sections support three professional outdoor surface finishes to adapt to diverse environments and design needs:

• Anodizing: Scratch-resistant, stable color, suitable for conventional urban building facades

• Powder Coating: Rich color options, excellent decorative texture for personalized facade design

• PVDF Fluorocarbon Coating: 25–30 years service life, anti-UV, anti-salt spray and anti-acid rain, perfect for coastal and high-pollution areas

Technical Specifications
