At LOONG'S ARC, we bridge ambitious architectural geometry and real-world execution through rigorous structural engineering. Backed by international code compliance, an integrated digital workflow, and proprietary connection details, we deliver reliable, precise, and efficient structural steel and envelope solutions for projects worldwide.
ENGINEERING & INNOVATION
Engineering built for multi-regional compliance.
We design and fabricate in accordance with major international standards—including North American (AISC, AWS, CWB), European (Eurocode, EN 1090 EXC3), and Chinese (GB) codes. Our team ensures that every structure meets local safety, seismic, and environmental requirements wherever your project is located.
Global Design Codes & Compliance
An integrated digital workflow from parametric concept to fabrication.
Digital Engineering & Software Stack
Connection detailing that balances load capacity with clean architectural lines.
Joints are critical to structural performance and aesthetics. We specialize in custom cast steel nodes, concealed bolting systems, and self-aligning assembly details tailored for long-span, curved, and Architecturally Exposed Structural Steel (AESS 4) applications.
Structural Joint Innovations
Envelope System & Node Innovations
High-performance building enclosures engineered for thermal efficiency and weather tightness.
