Steel structure engineering is one of the main types of building structures and is one of the more common structural forms in modern building engineering. China was the earliest country to manufacture load-bearing structures using iron、 and steel structure engineering is a structure mainly made of steel. Iron was already used as a simple load-bearing structure during the reign of Emperor Qin Shi Huang (246-219 BC)、 while Western countries only began using metal load-bearing structures in the 17th century.
