1800㎡ staggered double-linked steel structure workshop frame installation in Boston, USA
Recently, the large-scale steel structure workshop project in Boston, USA, for which Canglong Group provided a one-stop service from detailed design, complete material supply, cross-border logistics and customs clearance to remote installation guidance, has achieved a breakthrough. The main steel structure frame has successfully passed the stringent US standard inspection and is now complete.
Located in Boston, a city where American history and culture intertwine with modern industry, the project faces extremely complex terrain conditions. Canglong’s technical team, adapting to local conditions and leveraging its superior structural engineering design and high-precision Chinese manufacturing capabilities, created a staggered double-linked production base for the North American client, combining efficient space utilization with modern industrial aesthetics.
Ingenious Space Planning
The most challenging yet most remarkable aspect of this project lies in its unique sloping terrain. Instead of blindly undertaking large-scale excavation and filling, the design team followed the natural topography, ingeniously designing a double-layered functional interconnected space.
Core Specifications: The building measures 60.77 meters long and 30.92 meters wide, with an eaves height of 13 meters and a total floor area of nearly 1800 square meters.
Low-level Sloping Base: Material Storage Workshop. Utilizing the natural elevation difference between the sloping base and the flat ground, a robust and compact lower-level workshop was constructed, dedicated to storing raw materials and core materials, achieving efficient low-level turnover of heavy-duty materials.
High-level Sloping Top: Core Production Workshop. The upper flat and open area serves as the main production workshop. The large-span, high-clearance design provides extreme flexibility for the layout of automated production lines. The two levels work in tandem, maximizing the efficiency of logistics throughput in the three-dimensional space.
Rugged Framework
To combat Boston’s snowy winters and humid summers, the project’s framework system meets extremely high standards in terms of mechanical strength and corrosion and weather resistance.
Classic Portal Frame: Utilizing a portal frame structure with a main span exceeding 30 meters, the 13-meter-high ceiling provides ample flexibility for future installation of heavy-duty cranes or high-legged shelving.
High-Strength Steel: The main load-bearing beams and columns are uniformly constructed using high-tensile and high-bending-strength H-beams, forming the building’s earthquake-resistant and wind- and snow-resistant steel frame system. The secondary structure is fully equipped with high-precision CNC prefabricated C-shaped steel purlins, forming a stable three-dimensional geometric stress grid.
A Balanced Enclosure System
In the planning of the enclosure system, this project perfectly integrates the building’s functionality with Boston’s local community landscape regulations.
The Fusion of Brick and Metal: The lower half of the building’s enclosure uses robust and thick brick walls, effectively resisting lateral soil moisture from the terrain and giving the building a stable base. The upper half of the building and the entire roof utilize lightweight, high-strength modern metal panels.
Dual Advantages of Waterproofing and Weather Resistance: The profiled metal sheet system boasts excellent drainage slope and airtightness. Combined with the standard high-capacity gutters and downpipes, it easily withstands Boston’s unpredictable rain and snowstorms.
One-Stop Delivery
The building approval process in Boston is extremely lengthy, and local labor and hoisting costs are exceptionally high. Canglong Group maximizes the certainty of multinational factory construction through a one-stop, full-package delivery model.
Closed-Loop Turnkey Service: Canglong not only provides detailed design schemes that pass US building code review, but also handles precision manufacturing in the factory, international booking and transportation, and all the complex customs clearance and documentation.
100% On-Site Welding-Free: All H-beams and columns undergo precision welding of the gusset plates by automated welding robots and high-precision CNC punching before leaving the factory. Materials are transported to the Boston construction site in batches via 40HQ containers according to the construction sequence.
Full installation guidance: With remote high-definition 3D BIM installation guidance provided by Canglong Group engineers, the local construction team assembled industrial building blocks, with all bolts used for rigid fastening, zero cutting and zero hot work on site, directly shortening the on-site installation period by more than 50%.
