| Product List |
A prefabricated steel structure building is a bolt-together steel frame system in which every column, rafter, purlin, and connection plate is precision-cut, drilled, and welded in our factory — then containerized and shipped to your site for rapid assembly.
Unlike traditional on-site steel fabrication (which is slow, weather-dependent, and expensive in most countries), our approach delivers:
