What is the allowable deviation range of curtain wall aluminum profile wall thickness?

As the skeleton material of the curtain wall system, the accuracy of the wall thickness of the curtain wall aluminum profile is crucial to the stability of the entire curtain wall system. So, what is the allowable deviation range of the wall thickness of the curtain wall aluminum profile?

According to the national standard GB/T 5237-2017 “Aluminum Alloy Profiles”, the allowable deviation range of the wall thickness of the curtain wall aluminum profile has clear standards. Specifically, for curtain wall aluminum profiles with a nominal wall thickness of 1.5mm, the allowable deviation is ±0.15mm; and for profiles with a nominal wall thickness of 2.0mm, the allowable deviation is ±0.20mm. This regulation ensures the dimensional accuracy of the curtain wall aluminum profile during processing and installation, thereby ensuring the overall stability of the curtain wall system.

In the actual production process, in order to strictly control the allowable deviation of the wall thickness of the curtain wall aluminum profile, aluminum manufacturers need to start from multiple aspects. First of all, the mold design should ensure that the wall thickness of the aluminum profile is uniform to avoid uneven thickness. Secondly, the selection of materials and processing accuracy should be strictly controlled during the production process to ensure that each batch of aluminum profiles can meet the specified wall thickness requirements.

In addition, the inspection of curtain wall aluminum profiles is also an indispensable link. Through various inspections such as appearance inspection, dimensional measurement and mechanical property testing, the wall thickness deviation of aluminum profiles can be discovered and corrected in time to ensure that its quality and performance meet the standards.

In summary, the allowable deviation range of the wall thickness of curtain wall aluminum profiles is an indicator that needs to be strictly controlled. Only by ensuring the dimensional accuracy of aluminum profiles can the stability and safety of the entire curtain wall system be ensured.
