Aluminum Door Extrusions FAQ

Here are most of the questions related to aluminum door extrusions. We hope you will find the answer to your question. If not, please leave us a message.

What surface treatment would you recommend for aluminum door frame extrusions?2024-01-09T02:29:22+00:00

The ideal surface treatment depends on your preference and project requirements. However, there are several common surface finishes for these extrusions. Each has its pros and cons, which can help in choosing. One of them is powder coating, a process based on electrostatic charging. It offers different colors and is UV-resistant. If you are fascinated by the raw look of aluminum, you can try mill finish for aluminum sliding door extrusions. The extrusion is left as it is when it emerges from the extrusion die. If you are looking for a combination of corrosion resistance and decorative surface, consider the anodized surface. Get in touch and we will guide you about these and other surface treatment options.

Why should I pick an aluminum sliding door frame over uPVC?2024-01-09T02:26:06+00:00

The uPVC material may be more thermally efficient and affordable, but aluminum beats it in some crucial areas. For instance, aluminum is significantly stronger. This means that aluminum can support the design of sliding doors with a larger glass exposure area than uPVC can. Even on the initial price, the difference is sometimes not even notable. Aluminum can last for well over four decades while uPVC usually starts to deteriorate after 35 years. Adding the shorter life to the need for thicker frames, the return on investment for aluminum door extrusions starts to make more sense.

What is the recommended thickness for these aluminum door frame extrusions?2024-01-09T02:23:35+00:00

There is no specific recommended thickness for these extrusions. We can only talk about the minimum thickness, which is 0.8mm. Other than that, Fonnov Aluminum will always strive to deliver frame extrusions that fit the door design requirements. We would urge you to consider a few factors when determining the thickness of your aluminum door frame extrusion profiles. First, look at the exact design of your sliding door. Consult your contractor on the best thickness to order. You may even involve a designer.  The desired performance of the sliding door is another critical factor. While a thicker frame is good for security, it is more tasking to use. It might even be a safety hazard, say, where kids are involved.

Can alloys 6063 and 6060 match the lightweight and strength requirements for sliding door extrusions?2024-01-09T02:20:05+00:00

Yes, aluminum alloys 6063 and 6060 are ideal for sliding door extrusion applications in this respect. The aluminum extrusions are inherently strong, a reason why many users prefer it for applications added security is paramount. The sturdiness also comes with low weight, which adds to the performance and durability of the door extrusions. Being lightweight, the sliding door extrusions make the installation, use, and maintenance of the sliding door relatively easy.

How is the anodizing process carried out?2024-01-09T02:18:20+00:00

To anodize the sliding door aluminum extrusions, we immerse it in an electrolytic solution. This solution is often an acid. The aluminum is the anode (positive electrode) in this setup. To complete the circuit, we introduce the cathode (negative electrode). We then pass a direct current through the circuit. Thanks to the current, hydrogen is generated at the cathode. The anode side gets oxygen. Oxygen is formed on the aluminum side. Consequently, aluminum oxide forms a thick layer. Once this layer is formed, the alloy is protected. We can then dye the material to seal it even more for optimum durability.

Do the materials you use for sliding door aluminum extrusions withstand warping?2024-01-09T02:16:03+00:00

Yes, these doors are highly resistant to any form of deformation, including warping. The two popular alloys are balanced in composition which makes deformation highly unlikely. This feature works excellently together with the thermal stability of the metals. You can be sure that doors made from our extrusions will maintain their shapes. The structural integrity of the aluminum door frame extrusions also stays intact despite the prevailing weather. So, yes, the extrusions perform reliably for a long time.

How do you inspect the aluminum door extrusions for the highest quality?2024-01-09T02:14:13+00:00

Our quality inspection for the door extrusions is based on the need for the die design and the resulting extrusion to match. Further, the visual inspection focuses on any scratch marks, physical damage, stains, and die lines. We don’t give the product a quality pass until we have ruled out any form of imperfection on the aluminum door extrusions.

Inspection is done throughout the production process. The raw materials and machinery & equipment are keenly inspected for compliance to specifications.
