Project Milestones

Qinling Station on Ross Sea, Antarctica — steel structure assembled on site

Qinling Station Opens on Ross Sea — Built as a Fully Assembled Steel Structure

On 7 February 2024, China's fifth Antarctic research station — Qinling Station (74°56′S, 163°42′E) — officially opened on Inexpressible Island, Ross Sea. The station's main building was erected using a fully assembled steel structure with module-prefabricated interior units (modularisation rate 45%), a design that had to withstand extreme cold, katabatic winds and high UV radiation. The public record confirms the station building area of approximately 5,244 m² with capacity for 80 summer and 30 winter personnel.

Our company was the steel structure contractor for the Qinling Station project — the same team that delivered the Ross Sea New Station steelwork. The experience directly informs our low-temperature welding and arctic-grade coating specifications.

229 m span enclosed coal shed at Fangjiazhuang power plant, Ningxia

229 m Coal Shed Sets a Long-Span Record at Fangjiazhuang Power Plant

The enclosed coal shed at the Fangjiazhuang 2×1000 MW power plant (Guodian Ningxia / National Energy Group, Lingwu) uses a beam-string arched truss system with a 229 m clear span, 15 m truss spacing and a ridge height of 51.3 m. The structure was awarded the China Construction Steel Structure Gold Award (中国建筑钢结构金奖) — the highest category prize in China's steel construction industry.

The prestressed beam-string system (1670-grade cable, Q355B tubular members) combines the stiffness of a lattice arch with the economy of a tensioned chord — the solution we apply to bulk-storage enclosure projects worldwide.

Baiyun Airport T3 Steel Roof Topped Out — 118,000 m² of Steel Space Frame

On 29 April 2024, the steel roof of Guangzhou Baiyun International Airport T3 terminal was fully topped out. The double-curved space grid roof covers about 118,000 m² (equivalent to 16 standard football pitches), assembled from roughly 82,000 members and 18,000 welded hollow balls, with a total steel weight near 20,000 t. The roof was lifted in 35 staged sections using computer-controlled hydraulic synchronised lifting at 6–8 m/hour, with installation accuracy within 1 mm.

We supplied space-frame fabrication for the T3 roof package. The project is the largest airport expansion in Chinese civil aviation history, targeted for operation in 2025 with a design capacity of 120 million passengers per year.

Xianyang ancient ferry covered bridge across the Weihe River

748 m Xianyang Ancient Ferry Covered Bridge — China's First Qin-Style Two-Level Steel Footbridge

The Xianyang Ancient Ferry Covered Bridge (古渡廊桥) spans the Weihe River with a total length of 748 m and a deck width of 14 m, making it China's first covered pedestrian bridge in Qin architectural style with a two-level steel structure. The lower level carries pedestrian circulation; the upper level provides sheltered observation galleries with pavilions — an enclosed steel deck building on a multi-span river crossing.

Our team fabricated and erected the bridge steelwork. This project demonstrates how covered-bridge engineering combines bridge behaviour (movement, wind, corrosion) with building-envelope dead load on top — a combination we document in our bridge design guides.
