Centunion

What Centunion does

Centunion (legal name CENTUNION, S.A.) is a privately held Spanish general contractor founded in 1968 and headquartered in Madrid. The company specializes in the design, manufacture, and supply of steel structures with a primary focus on bridges, viaducts, and flyovers. Its core product line comprises flyovers (mixed steel-concrete and steel deck bridges), modular bridges (proprietary steel truss and multi-girder systems for spans of 30-120m), singular typologies (arch, cable-stayed, hanging bridges), and pedestrian walkways. The firm has installed over 25,000 linear meters of modular steel bridges across Southeast Asia and Africa, supported by ISO 9001:2015 and ISO 14001:2015 certifications.

The company operates an end-to-end EPC (Engineering, Procurement, Construction) business model, delivering turnkey project services from feasibility studies and pre-design through financing arrangement, manufacturing, logistics, construction supervision, and training. It maintains permanent regional offices in the Philippines (Centunion Filipinas), Kenya (Centunion East Africa Ltd), Serbia, and Finland, enabling direct engagement with government infrastructure clients across Europe, Southeast Asia, Africa, and South Asia. Revenue is generated through fixed-price project contracts with government and public works authorities, with no software, subscription, or recurring product revenue streams.

Centunion's customer base is exclusively governmental, including agencies such as Indonesia's Directorate General of Highways (114 bridges, 6,045 lineal meters, 1999-2015), the Philippines' Department of Public Works and Highways (91 bridges, 3,675 lineal meters), Kenya's National Highways Authority (T-Mall Flyover, Nairobi), Sri Lanka's Road Development Authority (Rajagiriya flyover), Angola's INEA, and Ivory Coast's AGEROUTE. Notable differentiators include proprietary modular bridge technology optimized for remote-area deployment, financing arrangement services (export credits, soft credits, project finance), and an EU Directive 2019/1937-compliant whistleblower channel. The firm employs 51-100 people and distributes exclusively through direct government contracting with no channel partners or resellers.
