We manufacture aluminum curtain wall profiles in both standard and custom specifications, using commonly applied alloys such as 6063 and 6061. Profile designs include vertical mullions, horizontal transoms, and structural frame members required for unitized and stick-built curtain wall systems. Options are available for wall thickness, section depth, and glass slot configuration.
Depending on the structural load, installation method, and façade layout, we can adjust alloy type and temper to meet performance needs. From technical drawing review to extrusion, machining, and surface treatment, we provide complete support to ensure each profile integrates correctly with your curtain wall design and building envelope system.

Communication is the first step to start a project. Simply upload CAD drawings, product images or provide samples, and we will perform DFM analysis and provide you with a quotation.
After confirming the production details we will make the first sample for you, and once you are satisfied with the sample we will start the batch production of your project.
For aluminum curtain wall profiles, consistent dimensional accuracy and structural reliability are essential to ensure proper assembly and long-term performance of façade systems. Profile quality is a key focus in our manufacturing process.
We provide OEM/ODM services and offer a complete production solution—from die development to extrusion, surface treatment, and processing. With a library of standard curtain wall profile dies and the ability to produce custom sections, we deliver profiles according to project specifications with stable quality and cost-effective production.
Surface finishing enhances the weather resistance, appearance, and service life of aluminum curtain wall profiles. Depending on environmental exposure and design needs, different treatments are applied to meet architectural, technical, and durability requirements.
Creates a controlled oxide layer on the aluminum surface through electrochemical treatment.
The charged aluminum profiles are immersed in a coating solution in an electrolytic tank. Through electrophoresis, the coating evenly adheres to the aluminum surface. Electrophoretic coating provides good weather resistance, color stability, and a smooth and uniform coating.

The most commonly used aluminum alloys for curtain wall profiles are 6063-T5 and 6061-T6, selected for their combination of strength, formability, and corrosion resistance in building envelope systems.
Both alloys are processed using controlled tempering methods to meet architectural standards and structural requirements. Our profiles comply with international specifications including EN 755, ASTM B221, and GB/T 5237, ensuring performance consistency across various curtain wall applications.
We provide complete in-house processing capabilities for aluminum curtain wall profiles, covering mold design, extrusion, thermal break assembly (if required), surface treatment, and profile fabrication. Our production setup is designed to meet the technical demands of unitized and stick-built curtain wall systems, ensuring accuracy in dimension, slot configuration, and mechanical properties.
We have one-stop production capabilities, providing services from aluminum extrusion profiles to surface treatment, additional processing and finished door and window assembly.
We support packaging according to your needs, such as outer boxes with your logo, customized profile packaging. If there is no special instructions, we will use our regular packaging.
We provide custom manufacturing solutions for aluminum curtain wall profiles used in unitized and stick-built façade systems. From extrusion and thermal break assembly to surface treatment and precision processing, our production is tailored to meet architectural, structural, and installation requirements. We support both standard designs and fully customized curtain wall systems for commercial, public, and high-rise buildings.
1. Design Input
Clients provide profile drawings, structural load requirements, and installation details. We also offer design support to optimize cross-sections and wall thicknesses.
2. Die Development & Sampling
Extrusion dies are created or adjusted for system-specific profiles. Sample runs are conducted for fit and finish confirmation.

Choose from 6063-T5, 6061-T6, and other 6000-series alloys. Finishing options include anodizing, powder coating, PVDF, or custom treatments.
4. Processing & Delivery
Profiles are cut, machined, and packed based on fabrication and site needs. Full support is provided from prototype to mass production.
An aluminum curtain wall profile is an extruded aluminum section used in non-load-bearing façade systems. It forms the structural framework that supports glass panels, spandrels, and other cladding elements in unitized or stick-built curtain wall systems.
We primarily use 6063-T5 for standard curtain wall framing due to its good extrudability and surface quality. 6061-T6 is available for reinforced or load-bearing profiles where higher strength is required.
Yes. We support custom profile development based on façade system requirements, including mullion depth, glazing slot size, pressure plate fit, and thermal break integration. Die design services are included.
Yes. We produce profiles for both systems. Unitized systems use pre-assembled panels; stick-built systems are assembled on site. Profile design will vary depending on your chosen system and project requirements.
Available surface finishes include anodizing, powder coating, PVDF coating, and wood grain transfer. Finish selection depends on the environment (e.g., urban, coastal, high-rise) and visual design needs.
Yes. We manufacture thermal break profiles using PA66 GF25 polyamide strips, inserted via mechanical crimping. This improves insulation performance and supports energy-efficient façade design.
Yes. We offer cutting, CNC machining, slotting, punching, and hardware mounting preparation based on fabrication drawings or project specifications.
Our profiles comply with international standards such as:
These ensure dimensional tolerances, surface treatment quality, and mechanical strength.
An aluminum curtain wall system is a non-load-bearing external façade made of extruded aluminum frames and infill materials such as glass or metal panels. It is designed to resist wind loads, allow light penetration, and protect the building envelope from external elements.
Common system types include:
Each system varies in installation speed, site logistics, and structural detailing.
Profiles include vertical mullions, horizontal transoms, pressure plates, cover caps, and back frames. These are extruded from 6000-series aluminum alloys and designed to match glass thickness, hardware, and drainage needs.
The most used alloys are:
Both comply with EN 755, ASTM B221, and GB/T 5237 standards.
Standard surface finishes include:
Selection depends on environmental exposure and aesthetic goals.
Yes. We manufacture thermal break profiles with PA66 GF25 polyamide strips inserted between inner and outer aluminum sections. This reduces heat transfer and improves energy performance in building façades.
We support full customization, including cross-section geometry, slot configuration, wall thickness, and surface treatment. Custom dies are developed to meet specific structural and architectural project requirements.
