Welcome to Wikipedia. Everyone is welcome to contribute constructively to the encyclopedia. However, please do not add promotional material to articles or other Wikipedia pages, as you did to Steel square. Advertising and using Wikipedia as a "soapbox" is against Wikipedia policy and not permitted. Take a look at the welcome page to learn more about Wikipedia. Thank you.
