Overseas Project Showcase: Free-Form Steel Structure Buildings

As architectural design continues to push boundaries worldwide, free-form steel structures — with their high strength, light weight, and superior formability — have become the preferred solution for landmark architecture. With years of experience in overseas steel structure markets, our company has served clients across the Middle East, Southeast Asia, Central Asia, Europe, and the Americas, delivering structural detailing, fabrication, and professional erection services for commercial complexes, convention centers, sports venues, airport terminals, and more.

In compliance with client confidentiality requirements, the projects below are presented in anonymized form, showing only project regions, building types, and engineering parameters, to highlight our technical expertise and delivery capability in free-form steel structures.

Case 1: Commercial Complex in the Middle East — A Double-Curved Dome over a Waterfront City

Located in the waterfront downtown area of a Middle Eastern city, this high-end commercial complex integrates a shopping mall, a hotel, and office space. Our company undertook the structural detailing and fabrication supply, supporting the owner and general contractor throughout the entire process.

Project Location

Waterfront downtown area, Middle East

Building Type

High-end commercial complex (shopping mall + hotel + office)

Project Scale

Approx. 120,000 m² gross floor area

Scope of Services

Structural detailing and fabrication supply

Structural Highlights

Irregular double-curved dome roof approx. 80 m in diameter, formed by twisted members and space trusses; large-span curved portal frame at the mall entrance with a maximum cantilever of approx. 28 m

Challenges & Solutions

Twisting/bending fabrication and 3D lofting of double-curved members; temperature effect control in a hot climate; digitalized survey and staged erection for precise high-altitude closure

Case 2: Convention Center in Southeast Asia — Wavy Roof, Flowing City Skyline

This newly built international convention center in Southeast Asia integrates an exhibition hall and a conference center as one facility, serving as a key urban public landmark. Our company was engaged as the steel structure specialist subcontractor, covering detailing, fabrication, and on-site erection.

Project Location

Southeast Asia

Building Type

International convention center (exhibition hall + conference center)

Project Scale

Approx. 80,000 m² gross floor area

Scope of Services

Steel structure specialist subcontract (detailing + fabrication + erection)

Structural Highlights

Continuous wavy spatial truss roof over the main exhibition hall, with a maximum span of approx. 72 m, creating a flowing skyline; large cantilever shuttle-shaped steel structure at the conference center entrance

Challenges & Solutions

Segmental fabrication and integral lifting of the large-span wavy truss; coordination of multi-wave elevation levels; ground assembly combined with synchronized hydraulic lifting to lift in one operation and minimize high-altitude work

Case 3: Sports Venue in Central Asia — Annular Cantilever Roof with a Lightweight Look

This comprehensive sports venue in Central Asia comprises a 20,000-seat main stadium and a training hall. Our company supplied and installed the grandstand steel structure and the roof system, providing a safe and reliable support system for sporting events.

Project Location

Central Asia

Building Type

Comprehensive sports venue (20,000-seat main stadium + training hall)

Project Scale

Main stadium roof coverage approx. 26,000 m²

Scope of Services

Supply and installation of grandstand steel structure and roof system

Structural Highlights

Asymmetric annular curved roof with an outer cantilever of up to 32 m; inner ring with compression ring and cables acting in composite action, presenting a lightweight appearance

Challenges & Solutions

Circumferential tolerance control of annular curved members; deformation control at cantilever tips; workshop pre-assembly and zone-based erection keeping the overall closure tolerance within millimeters

Case 4: Airport Terminal in Europe — Double-Curved Lattice Shell Roof, High-Standard International Delivery

This new terminal of an international airport in Europe features a continuous wavy double-curved roof, as part of a key airport expansion program. Our company undertook the structural detailing and member fabrication for the terminal, with the entire process executed under European standards.

Project Location

Europe

Building Type

International airport terminal

Project Scale

Roof coverage approx. 40,000 m²; maximum column spacing approx. 36 m

Scope of Services

Structural detailing and member fabrication (per EN 1090)

Structural Highlights

Continuous wavy double-curved lattice shell roof with cast steel spherical joints; hot-dip galvanizing plus fluorocarbon coating system designed for coastal high-humidity environments

Challenges & Solutions

Bidirectional twisting/bending fabrication of double-curved members; full-process quality control and certification under European standards; weatherability verification of the coating system
