Can scaffold fasteners of different materials be used together?
Thread Content
Recently, I went to a construction site to inspect the scaffolding and found that fasteners of different materials were being used together (cast iron and alloy steel). I assumed that they shouldn’t be used together, as their load-bearing capacity and tensile strength vary. However, after returning to the office and checking GB 15831-2006 \"Fasteners for Steel Pipe Scaffolds\" as well as JGJ130-2011 \"Safety Technical Specifications for Fastener-Type Steel Pipe Scaffolds in Building Construction\", I didn’t find any information on this matter. If anyone knows something about it, please help me out!
It seems the standards haven’t taken this aspect into account yet
Not necessarily; if the specifications don’t mention it, it’s likely that the developers simply don’t want to discuss this issue with the users. I once talked to someone who reviewed documents: such issues are not within the scope of consideration, so there’s no need even to bring them up.
