China Railway Sixth Group Completes Roof Enclosure of Vietnam Wind Turbine Blade Factory Combined Workshop

en.Wedoany.com Reported - On August 24, the combined workshop of the Vietnam Wind Turbine Blade Factory project undertaken by China Railway Sixth Group completed the overall roof panel enclosure. With a building area of 100,921.7 square meters, the combined workshop transitioned from open-air to enclosed construction after the roof cladding work was completed. The project has not yet reached the stage of workshop completion or equipment commissioning.

Located in Khanh Hoa Province, Vietnam, the project has a total construction area of approximately 120,000 square meters, comprising 10 individual structures including the combined workshop, office building, and canteen, along with supporting site roads, a wind turbine blade turnover yard, and a storage yard. China Railway Sixth Group undertakes civil works, steel structure installation, decoration and finishing, and outdoor engineering. According to project progress released in April, the steel components of the combined workshop had been hoisted at that time, and this roof enclosure marks the subsequent cladding milestone following the steel structure work. China Railway Sixth Group stated that this combined workshop is currently the industrial building with the largest span and the largest single-building floor area in Khanh Hoa Province.

During the peak construction period, the project deployed over 400 construction and management personnel, equipped with 7 units of 50-ton truck cranes, 6 aerial work platforms, 4 truck-mounted cranes, 6 precision measuring instruments, and 1 fully automatic intelligent roof sheet forming machine. Roofing materials were stockpiled in advance via sea freight, including over 400 tons of steel coils for roofing and over 1,000 tons of primary roofing materials.

In response to the local high-temperature, high-humidity, salt-spray, and heavy rainfall environment, the construction team adopted digital cutting, laser layout, segmented alignment verification, and closed-loop error control to manage the dimensions, seam gaps, and flatness of roof panels throughout the entire process. Procedures such as panel seam lapping, edge trim pressing, sealant application, and fastener anti-corrosion treatment were implemented using waterproofing and anti-corrosion standards adapted to tropical environments. The roof slope was adjusted based on local meteorological data to meet drainage, seepage prevention, and corrosion resistance requirements.

The roof enclosure provides enclosed working conditions for subsequent interior and equipment works. In the next phase, the project will advance wall enclosure, pipeline embedding, and fire protection system installation, followed by the mobilization, installation, and commissioning of large-scale production equipment.
