Steel structure purlins are critical components in modern metal buildings. This article explains what purlins are, why they matter in structural performance, types, installation, benefits, and real-world applications such as warehouses and industrial buildings. It also includes key technical comparisons, FAQs, and strategic insights to help engineers and project managers make informed decisions.
Steel concrete formwork has become a critical solution in modern construction due to its durability, precision, and cost efficiency. Compared with traditional timber formwork, steel formwork offers higher reuse cycles, better surface quality, and improved structural consistency.
On January 12, 2025, Liweiyuan Steel Structure Co., Ltd. successfully completed the production and loading of a custom-made steel carport for Micronesia, marking the official implementation phase of the cooperative project.
On January 9, 2026, Qingdao Liweiyuan Steel Structure shipped its first batch of six modern steel structure pig farm components, weighing approximately 30 tons, to a Uruguayan client. These pig farms feature a modular design with ventilation, insulation, and environmental protection functions, meeting the Uruguayan client's needs for expanding pig farming scale and improving efficiency. This marks a further expansion of the application of Chinese steel structure products in South American agriculture. The Uruguayan agricultural department stated that the introduction of Chinese steel structure pig farms will help improve the modernization level of the country's pig farming and strengthen agricultural cooperation between Uruguay and China.
On December 28, 2025, the main components of a steel structure warehouse customized by Qingdao Liweiyuan Steel Structure for a client in the Cayman Islands were successfully produced and shipped. The warehouse utilizes a high-strength galvanized steel structure system, designed with full consideration of the Cayman Islands' tropical maritime climate. It boasts excellent performance characteristics, including resistance to category 12 typhoons, corrosion resistance, and high-temperature resistance, with a service life of up to 50 years.
On December 18, 2025, the customized steel structure processing project undertaken by Qingdao Liweiyuan Steel Structure Processing Plant for a Philippine client was in its critical production stage. Addressing the hot and rainy climate of the Philippines and the client's specific requirements for corrosion resistance and load-bearing capacity of the steel structure components, the project team, in collaboration with the design team, completed multiple rounds of design iterations. This involved using special steel with stronger weather resistance and employing the most advanced large-scale CNC laser tube cutting machine in China for drilling, cutting, and processing each steel structure component, ensuring that the component's accuracy error is controlled within ±2 mm.
