Curtain Wall Aluminum Profile System

Structural curtain wall mullion and transom profiles for commercial high-rise facades.

Product Overview

Stand in front of any modern office tower in Ho Chi Minh City, Bangkok, or Jakarta, and what you're looking at is almost entirely aluminum. The glass facade that gives the building its contemporary appearance is held in place by an aluminum curtain wall system — a network of mullions and transoms that carry the glass panels, resist wind loads, and manage water infiltration across the entire building height.

Curtain wall design is one of the most technically demanding applications for aluminum profiles. The mullions need to be structural — carrying wind loads of 2.5–4.0 kPa on high-rise facades in typhoon-prone regions — while also being thermally broken to prevent condensation on the interior face. They need to accommodate the differential movement between the building structure and the facade (typically 10–15mm per floor due to slab deflection and thermal expansion). And they need to look good, because the facade is the first thing anyone sees.

Our curtain wall profiles are manufactured from 6061-T6, which provides the higher strength needed for structural mullions. The standard system includes 100mm, 150mm, and 200mm depth mullion profiles, with matching transom and pressure plate profiles. The thermal break version uses PA66 GF25 polyamide bars to interrupt the aluminum-to-aluminum conduction path, achieving U-values of 1.8 W/m²K — sufficient for green building certification in most Southeast Asian markets.

We supply curtain wall profiles to facade contractors across Southeast Asia, supporting projects from small commercial buildings to large-scale high-rise developments. Our technical team can provide structural calculations for mullion sizing, thermal performance calculations for energy code compliance, and fabrication drawings for the assembly sequence. We understand that facade contractors are often working under tight schedules, and we prioritize on-time delivery for curtain wall projects.

System Interfaces, Fabrication and Delivery Controls

Architectural profiles must be bought as an interacting system. Frame, sash, glazing bead, gaskets, hardware, drainage and finish need to be checked together rather than ordered as isolated section shapes.
