The main steel structure of the large workshop project in Peru has been completed
Canglong Steel Structure, with its focus on full-cycle service and precise delivery, has created a benchmark project for a modern workshop for a high-end industrial client in Peru. Its one-stop solution covers the entire process from design to implementation, earning high praise from the client for its technical strength and sense of responsibility.
This project is positioned as a comprehensive industrial workshop integrating production and warehousing. Considering the variable climate and high-intensity operational requirements in Peru, the Canglong team adopted a portal frame structure system in the early design phase. This maximizes site utilization through a large-span, high-clearance spatial layout, while also ensuring structural stability and economy. The main steel structure uses Q355B grade low-alloy high-strength steel, whose excellent tensile strength and low-temperature impact toughness are perfectly suited to the large diurnal temperature range of South America, laying a solid foundation for the long-term safe operation of the workshop.
The beams and columns all use hot-rolled H-beams, which have high section modulus and strong bending resistance. Combined with precise node calculations, this effectively reduces steel consumption. The roof and wall purlins innovatively utilize galvanized C-shaped steel with a hot-dip galvanized surface treatment (zinc layer thickness ≥275g/㎡). Combined with factory pre-punching technology, this not only extends corrosion resistance but also simplifies on-site installation.
In terms of service chain extension, Canglong demonstrated strong resource integration capabilities.
On the design side, BIM technology was used to complete 3D modeling and clash detection, optimizing node structures for Peru’s earthquake fortification intensity and outputting a complete set of drawings conforming to local standards.
On the manufacturing side, its own 120,000㎡ intelligent workshop achieves automated H-beam assembly, efficient submerged arc welding, and dual protection with shot blasting and epoxy zinc-rich primer, controlling the error of key components within ±2mm.
On the logistics side, a customized reinforcement solution was implemented for transoceanic transportation, using dedicated containers stacked in layers and tracked by GPS throughout the process, ensuring that over 100 tons of components arrived at the Port of Lima with zero deformation.
On the installation side, senior engineers were dispatched to provide on-site guidance. Through modular hoisting and temporary support systems, the main frame was erected in just 45 days, shortening the construction period by 20% compared to traditional methods.
Currently, the main steel structure frame construction is complete. The portal frame rises like a steel spine, and the standardized layout with a 9-meter column spacing and clear axis markings demonstrate the rigor of industrialized construction. The subsequent enclosure system has been fully upgraded. Both the roof and walls use 75mm thick polyurethane sandwich panels, which combine thermal insulation, fire resistance (B1 grade), and wind uplift resistance. The fluorocarbon coating on the surface resists UV aging. A complete set of accessories is provided, including thermally broken aluminum windows and doors (airtightness level 8), UPVC drainage pipes (highly weather-resistant), curved color steel gutters (with precisely calculated drainage slope), φ20 round steel tie rods, and turnbuckles, truly achieving a “turnkey” delivery.
From blueprints to industrial plants standing at the foot of the Andes Mountains, Canglong, driven by both technology and service, has not only saved clients 30% on coordination costs but also set a new benchmark for overseas projects with its “Made in China” quality. As the enclosure system installation enters its final stages, this workshop, embodying the wisdom of Sino-Peruvian cooperation, is about to go into production. Canglong’s one-stop service model will continue to shine in more international projects.
