If it is discovered, it is a tolerance.
Gb glass thickness 5mm, actual 4.8-4.9mm
Non-standard actual only 4.2-4.5mm, special attention should also be paid to.
Most village wall thickness can meet the national standard, and low floors can be put loose, tall floor glass wall thickness can be strengthened.
2. How to distinguish primary aluminum from recycled aluminum?
