3 Ways To Color Aluminum Windows
What methods are used to color aluminum windows?
Anodization
Powder-coated finishing
Wood color aluminum
Aluminum windows appear in a wide range of colors, but did you ever wonder how they came to be that way? There are many ways to color aluminum windows. From powder coating to Anodization, many professionals use these methods to add a touch of design to your window.
However, what many don’t know is that coloring an aluminum window is about more than just aesthetics. It’s also a method of protecting and finishing. Without a protective layer, the aluminum is entirely exposed to the elements, and eventually, a chemical reaction called oxidization will occur. Over time, this oxide collects and becomes more prominent on the aluminum.
What is mill finish?
When an aluminum extrusion is created, its raw form is called mill finish.
Mill finish retains many of the original properties of cast aluminum, with its natural appearance depending on the specific metals used in its production. In general, it is characterized by flat and even surfaces with a few soft, white oxidation spots and maybe even dye and tooling marks.
While it is entirely possible to make a window or door in mill finish, the entire surface is going to be exposed and therefore unprotected. If you want to preserve the integrity, appearance, and durability of your aluminum extrusions, it’s best to add this layer of protection—and fortunately, it looks good as well.
Now that we’ve discussed architectural aluminum in its rawest form, let’s take a look at how it’s colored and protected with finishes.
Anodization
Anodizing aluminum involves applying a coating of oxide that, in contrast to the natural oxide that forms when the metal is exposed to the environment, is both attractive and protective. It enhances the durability and corrosion resistance of aluminum.
This coloring method has been used to finish aluminum as early as the 1930s. It’s the only finishing process that virtually replicates the appearance of untreated aluminum, though other shades of the metal are available.
Anodized aluminum does not come in many colors, unlike its powder-coated counterparts, but it remains very popular with architects to this day because it offers high protection and retains aluminum’s original metallic appearance.
Powder-coated finishing
Powder coating is the most familiar kind of finish for most people, thanks to its very wide range of over 200 possible colors. The coating material is made from various resins and polymers and is often combined with pigments, flow modifiers, curing agents, or other additives.
The coating is similarly applied onto the aluminum to spray paint. The method is called electrostatic spray deposition, and in it, a powder spray tool precipitates the particles of coating onto the aluminum.
At sawin sazeh Aluminum, we powder-coat our aluminum profiles through an ISO machine . All this is to ensure that our aluminum windows and accessories have excellent quality, durability, design, corrosion resistance, and cost-effectiveness.
Wood color aluminum
Aluminum color finish process is a heat transfer system, based on the physical reaction that makes the inks, from a solid stage, become gas and again a solid. At the precise temperature and pressure, the pigment inks transfer from the paper support and move into the synthetic layer of powder coating, fixing the original color and position into it.
A powder coat base that is applied to our aluminum substrate and heated precisely under controlled conditions.
Upon cooling, the woodgrain ink is applied using a plastic envelope of heat transfer inks, smoothed and vacuumed to remove any trapped air.
Regulated warming of the transfer elements, facilitates an ideal finish bond for exterior applications.
Finally, the plastic envelops of patterned ink vaporizes, leaving behind a stable woodgrain finish pattern that is unified with the powder coat base.
Advantages of Aluminum Wood color
The wood color on the aluminum profile is a highly durable product that is easy to clean and does not require any maintenance on the solid wood. It is highly resistant to heat, acid, humidity, salt, detergents and ultraviolet rays. Therefore, it is very suitable for indoor and outdoor residential and commercial building applications.
Appearance grade
The biggest advantage of wood color aluminum is that it can be used for indoor and outdoor applications. The aluminum, packaging layer and glue have all undergone extensive testing to ensure long-term performance.
This article discussed Three of the most common ways to color aluminum windows. While there are other ways to color aluminum, these two are the methods used for architecture and building design.
