The South African Iron and Steel Trades Association (SAISTA; Afrikaans: Suid Afrikaanse Yster en Staalbedryfsvereniging) was a trade union representing white metalworkers in South Africa.
The union was founded in 1936, with support from the Nasionale Raad van Trustees.
It attempted to form a trade union federation restricted to white workers, but was unable to do so, and instead in 1944 affiliated to the South African Trades and Labour Council (SAT&LC).
[1][2] Within the SAT&LC, the union argued against representation for black workers, and in 1947 it resigned over the issue.
The following year, it was a founding affiliate of the all-white Co-ordinating Council of South African Trade Unions, and then from 1957 part of the larger South African Confederation of Labour (SACOL).
