Material of Aluminium Window Profile

The material of an aluminium window profile is primarily aluminium. This metal provides a strong, lightweight, and durable framework for the window. Aluminium window profiles are often extruded, meaning they are formed by pushing aluminium through a die to create a long, seamless profile that can be cut to size.
Aluminum window profiles are made of aluminum alloys such as 6063, 6060, 6061, 6005, and 6082 12. These alloys are known for their corrosion resistance and strength-to-weight ratio. The aluminum billet used to make these profiles is typically of national standard .
To enhance the performance characteristics of the window profile, aluminium may be alloyed with other elements, such as copper or zinc, to increase its strength. Additionally, the surface of the aluminium can be coated with paint, anodized, or finished with a powder coating to improve its appearance, resistance to wear, and protection against the elements.
In some cases, other materials may be used in conjunction with the aluminium, such as polyamide or thermal breaks to improve insulation and reduce heat transfer. These materials are often integrated into the design of the window profile to create a more energy-efficient product.

Process of Aluminium Window Profile

The process of manufacturing aluminium window profiles involves several steps, from raw material selection to final product testing. Here is an overview of the typical process:

Ingot casting: The process involves the ingredients, melting, casting, and homogenization of the aluminum billet.

Extrusion: The billet is heated and placed onto an extrusion press, which passes it through a die and goes through several processes to ensure it is straight, strong, and of the required quality. The extrusion process includes an automatic production line composed of ingot heating, extrusion, cooling, straightening, cutting, and other processes .

Heat treatment: The profile undergoes different systems for quenching and aging treatment to obtain the mechanical properties of the profile .

Surface treatment: The aluminum profile is treated with a series of cleaning and pre-treatment processes to prepare it for painting. It is then powder-coated in a specialist powder coating booth and cured in specialist ovens .

Assembly: If the profiles are to be used in window frames or other assemblies, they will be joined together using mechanical fasteners, adhesives, or other methods.

Quality Control: Throughout the manufacturing process, quality control measures are performed to ensure that the profiles meet the required specifications and standards for strength, durability, and appearance. This includes visual inspections, dimensional measurements, and testing for mechanical properties, corrosion resistance, and thermal performance.

Packaging and Shipping: Once the aluminium window profiles have passed all quality control checks, they are packaged for protection during transportation and are shipped to their final destination, where they will be used in window installations.

Components of Aluminium Window Profile

An aluminium window profile is composed of several components that work together to create a functional and secure window assembly. Here are the main components of an aluminium window profile:

Frame: The main body of the window, which provides structural support and houses the panes of glass.

Sash: The part of the window that can be opened and closed, typically composed of two or more panes of glass separated by a spacer bar.

Glazing: The glass panes that are fitted within the sash and frame. Double-glazed or triple-glazed windows have two or three layers of glazing, respectively, separated by a vacuum or filled with inert gas to improve thermal insulation.

Spacer Bar: A component that separates the two glass panes in a double-glazed window. It may be filled with desiccant to absorb any moisture between the panes.

Weatherstrip: Seals that prevent drafts, air leaks, and water intrusion between the sash and the frame.

Locks and Latches: Mechanisms that secure the window closed or allow it to be opened to various positions.

Hardware: Includes hinges, stays, and other components that facilitate the operation of the window.

Finishes: May include paint, anodizing, or powder coating that provides corrosion resistance and an aesthetically pleasing appearance.

Meeting Rails: The lower rail of the sash where the two sashes meet when the window is closed.

Trickle Vents: Small vents integrated into the window frame to allow for passive ventilation even when the window is closed.

Cover Cap: A protective cap that may be added to the exterior of the window profile to prevent water ingress and enhance the window's appearance.

How to maintain Aluminium Window Profile

To maintain your aluminum window profile, here are some tips:

Clean the window screens regularly: The window’s surface is susceptible to collecting dirt, dust, and grime, making it appear lifeless and gloomy. Use a gentle soap or glass cleaner, water solution, and a microfiber cleaning cloth to clean the door’s surface. Avoid using harsh chemicals or abrasive cleansers because doing so can ruin the door’s finish.

Lubricate the window’s moving parts routinely: The hinges and locks of old windows might experience unnecessary wear and tear over time, making them difficult to use and stiffer. Apply a lubricant that contains silicone to the moving elements to avoid this from happening. Simply add a very tiny amount of lubricant to the hinges and locks, and then open and close the door a few times to work the oil into the hinges and locks.

Inspect the seals and weatherstripping around your aluminum windows: Regularly inspect the seals and weatherstripping around your aluminum windows for any signs of wear, damage, or gaps. Replace damaged or worn-out seals to maintain proper insulation and energy efficiency. Clean the seals regularly to prevent dirt or debris buildup that can affect their effectiveness.

Protect from impact and abrasion: Protect your aluminum frame from damage caused by moisture and other environmental variables by weatherproofing it if it is located in an area where it is subjected to the elements. You can accomplish this by installing a weatherstrip made of silicone all the way around the window’s circumference.

Repaint the aluminum frame: If the aluminum frame of your door or window is starting to show signs of wear and tear, you should repaint it to make it brand new and give your home a more modern feel. However, before you start, you must ensure that the surface is properly prepared by washing and sanding it. This will ensure that the new paint will attach in the correct manner. Make sure the paint you use is of a high quality, exterior grade, and was developed expressly for use on metal.
