No corrosion problems with composite

The aggressive wastewater in treatment plants gradually causes traditional building materials to corrode - this problem is easily solved by using fibreglass composite instead, which is corrosion-free

Fiberline fibreglass profiles are particularly suitable for use in wastewater and chemical plants, as the material is corrosion-resistant and therefore resistant to wind, rain, chemicals and, not least, the water that flows through the plants every day. This also means that the fibreglass doesn't rust or rot and only requires minimum maintenance. This is also why our fibreglass profiles have an unrivalled durability and a long functional life, even in demanding conditions, and why they are an economic advantage in the long run. Great demands are placed on the materials that are used to cover the large aeration tanks at wastewater treatment plants. The air is full of hydrogen sulphide and other aggressive gases, and traditional materials therefore succumb and corrode, causing major safety risks.

Fiberline's planks and gratings, which have a non-slip surface, are therefore used in a number of wastewater and chemical plants in Europe for walkways, bridges, roofs and as lids on even very large structures, helping to increase staff safety. The fibreglass profiles can also be used to cover the wastewater tanks to reduce bad odours.

Our products

Combining advantages

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

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

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.
