Hybrid bridge by Fiberline



Hybrid bridges are bridges where load-bearing beams/girders and the deck consist of two different materials. Substructure made of steel girders and the deck of fibreglass is the most common constellation. However, it is also possible to have girders in reinforced concrete, aluminium or wood. Hybrid bridges combine the good properties of the materials optimally, for example, a steel substructure can contribute to large spans while an FRP deck is a lightweight and can contribute to the corrosion protection of the steel as it is waterproof.

Fiberline Medium Duty Plank
Fiberline Medium Duty Plank is designed with an excellent price-performance ratio. The plank weighs only 6.58 kg/m, making it easy to handle on-site. Like other products from Fiberline, plank MD is made of GFRP. This material has noteworthy properties such as a long, proven service life as well as high corrosion resistance and strength. Fiberline plank MD is also available with anti-skid surface

Fiberline Heavy Duty Plank
The strong Fiberline Heavy Duty Plank is suitable for applications were load requirements are 5 kN/m2 and point loads are 10 kN, e.g. decks for bike paths and pedestrian bridges. Plank HD is corrosion-free and has a long service life, even under demanding and corrosive conditions, e.g. swimming pools, industry and cooling towers settings as well as offshore. Other advantages include great strength, low weight and electrical insulation. Plank HD is also available with anti-skid surface.

Fiberline Ultra Duty Plank
The Ultra Duty Plank is our strongest bridge decking, designed to meet the most stringent load requirements for pedestrian and cycle bridges. The UD plank reduces the weight of the structure and is easy to work with at the installation site. It is also corrosion-resistant against a range of chemicals and salt water. Asphalt or PPMA/Epoxy strewn with sand or gravel can be used as a wearing surface.

How to video

The most advantageous way to mount an FRP deck on a substructure is by adhesive but mechanical connections are also possible. See our detailed instruction video regarding the bonding of UD Plank on a steel substructure here

CE marking

Our products have a number of international and highly sought-after certifications, among other, within the construction, offshore and railway sectors. This is your guarantee of consistently high quality every time you buy from us and use our products.

Low weight

Fiberline's GRP profiles are low in weight. This makes them easier to work with and means that great weight savings can be achieved on the finished structure.

Great strength

Fiberline Building Profiles give you the same great strength as steel, but at only a quarter of the density. It is also possible to make weight savings in comparison with aluminium, as the density is 30 % lower.


Our fibreglass profiles are resistant to aggressive chemicals, and liquids. This makes them ideal for wastewater treatment plants, swimming pools, cooling towers and construction, where there is a risk of corrosion.

Chemical resistance

Electrical insulation

Fiberline's GRP profiles provide electrical insulation and minimise the complexity of earthing. This makes our profiles a future-proof choice where the costs of both installation and future inspections can be reduced considerably.

Easy to work with

GRP profiles are just as easy and fast to work with as timber. This means that solutions which incorporate our profiles can be installed easily on site or adjusted to fit existing components, such as piping systems, etc.

Thermally Insulating

Fiberline's fibreglass profiles have a significantly lower heat distribution gradient than steel and aluminium, enabling energy-efficient end products.

Minimal maintenance

Our GRP profiles have unrivalled durability and a long life, even in demanding conditions.


Fiberline's fibreglass profiles are produced using an energy-optimised process that takes the environment into consideration.
