Global Certification Ready
CE (EN 1090), UL 2703/6703, TÜV, IEC 62446 certified. Documentation packages tailored for EU, US, MENA, APAC markets. Pre-approved structural calculations accelerate project permitting.
Precision Structural Engineering
In-house engineering team performs site-specific structural calculations (wind/snow/seismic loads) per IEC 61400, ASCE 7, Eurocode. All designs validated for 30+ years service life in extreme environments – deserts, coastal zones, alpine regions.
Vertical Integration Advantage
Full control from raw steel coil → hot-dip galvanizing (65μm+) → Zn-Al-Mg coating → precision fabrication. Eliminates third-party quality risks. Every component traceable with mill test reports and coating certificates.
True Project Customization
No "one-size-fits-all". We engineer solutions for your specific terrain, roof type, or application (carports, agrivoltaics, floating). 3D modeling + BIM support provided. MOQ flexible for pilot projects.
Rigorous Quality Assurance
100% in-line inspection: dimensional accuracy, coating thickness (XRF tested), weld integrity. Salt spray testing (2000+ hrs), load testing per project specs. ISO 9001 certified process with full traceability.
End-to-End Project Partnership
Dedicated project manager from inquiry to installation. Technical support includes foundation layout, installation manuals, video guidance, and on-site engineer dispatch if required. 25-year structural warranty.
