Floor railing pipe diameter
Thread Content
There are many prefabricated buildings in the chemical plant area, and railings need to be installed on the floors. What are the standards for selecting such railings? What should the pipe diameter and wall thickness be?
You can refer to GB4053, which sets requirements for columns, handrails, and crossbars
You can simply choose a steel pipe with D=38! !
Refer to the national standard catalogues: \"Steel Ladders\" 02J401, or \"Railings, Guardrails…\" 06SJ403 (which are more commonly used in civil applications); there are also specialized catalogues for railings in the chemical industry, though they are a bit old, dating back to around 1997.
Just choose a steel pipe with D=38×3! !
If you want to save money, you can use some old heat exchanger tubes and make do with them, haha.
