An established provider of long-span modular bridging

Mabey Bridge is a long-span bridging specialist. Launched in 2003, our high-quality long-span bridging solution, the Delta™, is a permanent, lightweight, modular steel bridge which features standardised, interchangeable steel components with full highway loading capability. The Delta™ can be configured as a single clear span of 100m. It can also be supplied in multiple spans, supported on intermediate piers, meaning that there is no limit to the length it can bridge.

Mabey Bridge has supplied the Delta™ to numerous customers around the world, from Canada to Chile and from the Philippines to Pakistan; a 328.5m Delta Bridge was installed in Pakistan's Swat Valley following severe flooding in 2010. In 2015, Mabey Bridge installed its first Delta™ in Latin America, in the Arauco region of Chile to replace infrastructure which had previously been destroyed by a severe earthquake. Most recently, we have been back to Pakistan to install more Deltas in Gilgit-Baltistan.

A thought leader in long-span bridge innovation

Mabey Bridge is a master of long-span bridging design. Our long-span Delta™ features an innovative proprietary steel decking system, and can accommodate special load requirements, site-specific topography, high wind loads and seismic requirements.

Extremes of temperature are also taken into consideration; we design using certified high-grade steels to provide a physically strong and durable product, which is hot-dip galvanised to international standards to protect it from corrosion. Additionally, full-scale testing, to verify design calculations and fatigue characteristics and to prove structural integrity, features as an integral process in our design statement methodology.

It is the versatility and robustness of the Delta Bridge's design, combined with its aesthetically pleasing triangular-shaped panels, which differentiates it as a superior high-quality product in the long-span market.

A world leader in speed of installation

Mabey Bridge’s expertise goes far beyond design and manufacture. We pride ourselves on the comprehensive bridge installation advice we offer our customers in support of their project to ensure their bridge installation is rapid, safe and trouble-free; our qualified bridge installation advisors are experts in site reconnaissance, planning, logistics, infrastructure development and installation, and have overseen the installation of thousands of bridges worldwide.

The Delta™ combines the best of off-site fabrication with high speed construction and rapid installation, offering significant advantages over more traditional construction techniques which involve major site work. Delta™ components can be transported to remote sites easily in ISO containers and bridges can be erected quickly using locally sourced labour and a minimum of specialist equipment.

Installation times are impressive; a 90m single-span Delta™ was built in Chur, Switzerland, in 16 days.

A globally trusted partner for the future of long-span bridging

There is more to Mabey Bridge. Our product development work continues to push Delta™ bridge developments: to continue to strengthen it so as to respond to industry’s demand for longer single spans; to accommodate new customer requirements and to identify new markets and applications.
