Scope

GB/T 5237.1-2017 is the English-translated version of 铝合金建筑型材第1部分：基材.

Part 1 of China's national standard for architectural aluminium alloy extruded profiles, covering mill finish material. This is the base of the whole series: the profile as it comes from the press, before any surface treatment, and the substrate on which Parts 2 to 6 build their anodised, powder coated, painted and thermally broken products. Nearly every window, door, curtain wall and balustrade in Chinese construction is made from these sections, which is an industry of tens of millions of tonnes. What this part fixes is what the rest depend on: the alloy and temper, the dimensional and form tolerances that decide whether a frame assembles squarely, the mechanical properties, and the surface condition the coating will have to adhere to. The part applies to hot extruded aluminium alloy profiles for architectural use in doors, windows, curtain walls and guardrails, and may be referenced for hot extruded tubes of the same purpose.
