Aluminium Curtain wall profiles
A curtain wall hangs on the structure of a building and carries only its own weight plus wind load. The frame is aluminium (aluminum in US usage) and the infill is glass or panels. Snalco extrudes the mullions, transoms, pressure plates, caps and glazing sections for these frames, and can design a new die if your system is not on our list.
| Snalco supplies curtain wall profiles in 6063-T5/T6 and stronger 6061 or 6082 for load-bearing mullions, finished in anodised, powder coat or PVDF, and cut to your lengths. |

Why aluminium suits curtain walls
- Light: about one third the weight of steel, so less load on the building frame.
- Corrosion resistant: a natural oxide layer, improved further by anodising or PVDF paint.
- Easy to shape: hollow sections, glazing pockets and drainage channels are extruded in one pass.
- Quick to install: parts are cut and drilled at the factory, so site work is mostly fixing.
- Recyclable: aluminium (aluminum) can be remelted again and again with little loss of quality.
Where curtain wall profiles are used
- Office towers and business parks
- Hospitals and campuses
- Airports, railway stations and exhibition halls
- Stadium canopies and skylights
- Retail frontages and showrooms
Finishes for outdoor facades
For exposed facades, PVDF paint and 2-step anodising are the usual choices because they hold colour in strong sun and monsoon rain. Powder coating is common on lower-cost projects, and wood grain suits entrance lobbies and interior-facing frames.
Why Snalco
- Own extrusion plant at Kosamba, Surat, built around a 1600 UST four-column hydraulic press that handles 6 inch and 7 inch billets.
- An in-house tool shop, so new dies and die corrections do not wait on an outside vendor.
- A working quality lab: spectrometer for chemistry, UTS machine, Rockwell and Brinell hardness testers, conductivity meter, metallurgical microscope and a profile projector for dimensions.
- Cutting to length, drilling, punching and machining done at the plant, so you can receive parts ready to fit.
How to order
- Section and size: dimensions in mm, wall thickness, and the profile number or drawing.
- Alloy and temper: for example 6063-T5, or 6061-T6 where more strength is needed.
- System: stick, thermal or unitized, plus the glass thickness the pocket must hold.
- Finish: mill finish, anodised, powder coated or another finish from the list above.
- Length and quantity: cut lengths in mm or full mill lengths, and the total weight or number of pieces.
- Delivery point: a city in India or an export port, so freight and packing can be quoted.

Aluminium curtain wall profile is a thin and lightweight wall system used for high-rise buildings. It is normally composed of aluminium and glass. And snalco is a leading aluminium curtain wall profile manufacturer and supplier with a very strong tie-up with various construction companies across India for the consistent and quality supply of aluminium curtain wall profile manufacturing.
As a professional aluminium extrusion factory, Snalco sells various high-quality aluminium extrusion curtain wall products, and our products have already been widely used in small to large architectural and commercial projects in India.
Moreover, as one of the most experienced aluminium curtain wall suppliers in India, we have the most professional engineering team. If our existing unitized aluminium facade systems are not suitable for your special purpose, our experienced engineers can also help you to design your own curtain wall aluminium profiles and realize custom aluminium extrusions.
Aluminium extrusions from our architectural systems are available in a variety of finishes which contain mill finish, clear anodized aluminium including 2-step electrolytic anodizing, powder coating, PVDF painting and wood-gram finish. We also offer aluminium extrusion fabrication services for bulk projects. If you are looking for trustworthy aluminium curtain wall suppliers, don’t hesitate to contact us.

Benefits of Aluminium Curtain Wall Profile
- Aluminium curtain wall profile is in high demand due to it’s rigidity, lightweight and high strength. Aluminium veneer curtain wall panels have good corrosion resistance, and the fluorocarbon paint can last for 25 years.
- The aluminium curtain wall profile has good workmanship. The aluminium plate can be processed into a variety of complex geometric shapes such as plane, arc and spherical surface by adopting the process of processing first and then spraying paint.
- The aluminium curtain wall profile is not easy to be stained and is easy to clean and maintain. The non-adhesiveness of the fluorine coating film makes it difficult for contaminants to adhere to the surface, and it has good cleanliness.
- The installation and construction of aluminium curtain wall is convenient and quick. The aluminium plate is formed in the factory, and the construction site does not need to be cut and simply fixed.
- The aluminium curtain wall profile can be recycled and reused, which is beneficial to environmental protection. Aluminium plate can be 100% recycled, with a higher recycling value.
Aluminium Curtain Wall Profile Application
The most important characteristics of Curtin Wall Profile in production are heat insulation, moisture resistance, and sound insulation, which can optimize the ambient temperature and light, thereby reducing the building’s demand for electricity.
On the other hand, the curtain wall, because it is a very light structure, reduces the overall load of the building, and is also very resistant to earthquakes. It is ultimately superior to other exterior walls in terms of installation, aesthetics and affordability.
The aluminium curtain wall is actually the chassis and lamps placed around the project. The glass used as the facade of the building is installed on the curtain wall structure, not on the building itself, so the weight shrinks in the building. This weight reduction increases the earthquake resistance of the building.
High-strength, light-weight and beautiful curtain walls are widely used as curtain wall panels and substitute solid wall structures. The curtain wall can be used as the outer wall, skylight and canopy of large-span buildings such as hospitals, office buildings, stadiums, airports, railway stations, exhibition centers, etc.
