Comprehensive Research Facility for Fusion Technology (CRAFT), also known as “Artificial‑Sun”, is a national major scientific‑infrastructure project of the 13th Five‑Year‑Plan. Situated in Hefei large‑science‑device cluster, the park contains 14 scientific‑research buildings and experimental workshops with total building area of 138,900 ㎡ for R&D of fusion core components such as superconducting magnet and divertor.

This project is custom‑manufacturing & contracting work for wall‑roof enclosure systems of multiple experimental and auxiliary buildings. Scientific‑research buildings impose strict indexes for roof waterproofing, air‑tightness, energy‑saving thermal‑insulation, wind‑resistance and anti‑corrosion, to satisfy constant‑temperature‑humidity requirement of precision laboratories and adapt heavy‑rain & strong‑wind climate in Anhui.

We undertook wall‑roof enclosure system works including detailed optimization, custom panel fabrication, accessory supply and on‑site installation. Complying strictly with specifications for scientific‑research buildings, we controlled panel precision and joint waterproof‑sealing workmanship, ensuring air‑tightness, water‑tightness and long‑term stability, supporting the completion and commissioning of this national major scientific infrastructure.
