On the curtain wall aluminum alloy wall thickness, the country has no standard?
<Glass curtain wall engineering technical specifications JGJ102-2003> open profile of not less than 3.0mm, such as beams are mostly open, one end with a cover closed. Closed profiles such as stand up, mostly closed type, not less than 2.5mm, which is only the minimum requirements of the wall thickness, but also according to calculate the calculation of the wall when used in the calculation of the wall.
For the aluminum alloy curtain wall of the main force components, such as columns, Heng expected. If the closed hollow section, the wall thickness of not less than 3mm, if the solid profile (or called unsealed profiles), the wall thickness of not less than 2.5mm. The country has curtain wall related standards.
