[China Aluminum Industry Network] Quality Standards: Vertical seam and wall verticality should not exceed 10mm within a height of 60 meters for the curtain wall.
Wallboard flatness must be within 2.0mm.
Straight seam straightness should be maintained at 2.0mm.
Horizontal straightness is also required to be 2.0mm.
Horizontal seam levelness needs to be controlled within 2.0mm.
Seam width tolerance is ±1.5mm.
The height difference between two adjacent panels should not exceed 1mm.
To ensure these standards are met, various detection tools are used, including laser theodolites, laser levelers, plumbometers, 3-meter rulers, calipers, and depth gauges.
These precision instruments help in achieving accurate measurements and maintaining high-quality construction standards. It's essential to follow these guidelines to ensure the structural integrity, aesthetic appearance, and long-term performance of aluminum curtain walls. Regular inspections during installation are crucial to identify and correct any deviations early on, preventing costly rework and ensuring compliance with industry regulations.
