I do not have information about the specific steel structure next to the Oval cricket ground. The Oval is a historic cricket ground located in London, England. However, stadiums and their surroundings can undergo changes and renovations over time, so it's possible that there may be a new structure built near the Oval cricket ground since then. To find the most up-to-date and accurate information about the steel structure you are referring to, I recommend checking with local authorities, cricket ground officials, or conducting an online search for recent updates and developments related to the Oval cricket ground.
