Portal Steel Structure & Prefab Factory Workshop
The steel portal frame industrial buildings feature a rigid frame structure design. The main structure utilizes high-quality steel materials, including both Q355B and ASTM A572 grades. These materials offer high strength and excellent toughness, effectively supporting various loads encountered during daily operations and providing a solid and reliable structural foundation for industrial production. The bolted connection system ensures convenient and efficient assembly with secure and stable joints. The structures feature clear spans of 10–50 meters and eave heights of 4–15 meters. Provision is made for crane installation (5–50 tons). The structures undergo hot-dip galvanizing treatment and have a service life exceeding 50 years.

Modern Manufacturing Workshop Steel Structure Factory Construction
Core Features & Advantages
Portal-frame steel structure workshops fundamentally represent a perfect alignment between structural characteristics and industrial requirements. By effectively addressing the pain points associated with traditional industrial buildings—such as spatial constraints and cumbersome maintenance—while simultaneously ensuring flexible adaptability and low-cost construction, they have emerged as the optimal choice for modern industrial facility development.
♦ High-strength steel, crane ready;
