Regarding the wall thickness of aluminum alloy profiles, are there any standards in the country?
< technical specification for glass curtain wall JGJ102-2003> open section bar is not less than 3.0mm. For example, the beams are mostly open and closed at one end with a cover plate. Closed profiles such as stand up, mostly closed type, not less than 2.5mm, these are only the minimum requirements for wall thickness, but also in accordance with the calculation of the book in the calculation of the wall thickness.
For the main force components of aluminum alloy curtain wall, such as column, transverse material and so on. Such as closed hollow profiles, the wall thickness of not less than 3mm, if the solid section (or known as non closed profiles), the wall thickness of not less than 2.5mm. The state has standards for curtain walls.
