How to choose aluminium profile 20x40

Simply knowing the type of 20x40 profile one needs is just the start. Buyers should also understand what makes a quality extrusion. Here are some factors to help select the best profile for clients.

Profile quality

Fabricators need to use the right alloys to create strong yet workable profiles. The two ideal alloys for 20x40 profile are 6060 and 6063. They are easy to shape while still providing strength. Avoid any older alloys like 1100 or 1350. They form easily, but won't give the profile the long-term strength it needs.

Surface finish

Their surfaces can undergo various treatments that enhance the profile's resistance to wear and corrosion. Anodizing basically thickens the oxide layer for greater protection and improved adherence of paints and adhesives. Powder coating adds to the anodized layer a thicker, colorful coat that safeguards the aluminum against scratches, dents, and UV exposure. Other than that, a brushed satin finish provides a sleek metallic aesthetic. At the same time, it hampers minor corrosion. Since these finishes come with different profiles, buyers should first check the purpose behind buying them. Then use that information to select the finish that will best suit those needs.

Joining techniques

Fabricators use many means to join the 20x40 aluminum extruded part. Some of these techniques include drilling, welding, and using corner brackets. They may even use rivets or tapping directly into the profile. Each technique has its pros and cons. For instance, drilling is quite simple but may weaken the joined parts. Meanwhile, a weld creates a perfect bond but needs someone with the right skills. That's why buyers should consider the joining techniques based on their clients' needs and budget.

Other factors

At times, a 20x40 aluminum profile may become quite hot due to the high temperatures it conducts. Although this isn't really a disadvantage, it pushes buyers to consider other electrical insulation materials. Likewise, rough handling may scratch or dent the profile. So, when selecting it, always think of how clients will use it. Will it be in a place that requires constant moving around of machinery? Or will it be in a construction site? Knowing its usage will help guide buyers in choosing a profile that will serve its intended purpose effectively.
