How To Choose Extruded Aluminum Profiles？

Material

The main materials of extruded aluminum profiles generally include three aspects: Aluminum profiles, glass, and hardware. The wall thickness of the aluminum profile used for high-quality aluminum alloy profiles should be more than 1.4 mm, and the thickness of the oxide film should reach 10 microns; for rack mount case and aluminum enclosure, yongucase is made of high-quality, corrosion-resistant aluminum alloy with super strong compactness.

Precision machining

High-quality extruded aluminum profiles, with fine processing, smooth tangent lines, and consistent angles, should not have obvious gaps during the splicing process, with good sealing performance and smooth switching. Inferior aluminum alloy profiles, especially extruded aluminum outdoor profile products, if the processing is unqualified, there will be problems of sealing properties, not only air leakage and rain, but also bursting and falling off under the action of strong wind and large external force.

Appearance

There should be no obvious scratches, scratches, bumps and other defects on the surface of the profile. There should be no obvious color difference between the colored surfaces of adjacent components on the profile. There should be no aluminum chips, burrs, oil spots or other stains on the surface of the profile, and there should be no spilled adhesive at the assembly connection. Yongucase has a professional design team and a 4.0 factory, which is operated by professional technicians. After that, the quality inspection department checks the product for defects. If there is any defect, we will treat it as invalid. After the quality inspection is completed, it will be shipped immediately in the afternoon of the same day.

Performance

The performance of extruded aluminum profiles usually needs to consider the following aspects: Strength, reflected in the selection of aluminum alloy profiles, whether it can withstand ultra-high pressure; air tightness, mainly reflected in the structure of the profile, the inner fan of the profile and the whether the outer frame structure is tight, etc.; water tightness, mainly to check whether there is water accumulation and leakage in the aluminum alloy profile; sound insulation, which mainly depends on the sound insulation effect of insulating glass and other special sound insulation airtight strip structure and opening and closing force, durability of other profile accessories such as opening and closing durability.
