For columns there is no specific code and it so happen to most of the columns manufacturer. It is not a common practice…
The way we order the column is always to type in the full description to ensure the product is in accordance to specification.
Some people choose to make record in shortcut in their final drawings or Spare Parts List and when the next person try to order, problem arise because the information is insufficient and so much time is wasted just to find out the correct specification.
So when you place order is the same always type in the full description.
