Fiberline's FRP U-profiles are a cost-effective alternative to timber, concrete, steel or aluminium. They are corrosion-free and do not deteriorate, which gives them a long life and saves you maintenance costs in the long term.


Fiberline's fibreglass I-profiles combine several unique properties such as outstanding stiffness-to-weight ratio and corrosion resistance in almost any environment. This makes the I-profiles a cost-effective alternative to steel and aluminum. 

Square tubes
Square tubes

GRP square tubes combine a number of unique advantages such as high strength, low weight and corrosions resistance, which provide a sophisticated, cost-efficient alternative to concrete, steel, aluminum and wood.

Angle profiles
Angle profiles

Working with our FRP angle profiles is very much like working with timber and does not require any special tools or welding. This makes them easy to fit and adjust to existing components on site, such as piping systems, etc.

Strip profiles
Strip profiles

We offer strip fibreglass profiles with a high level of quality. All of our structural profiles are CE-marked, which is your guarantee of consistently high quality every time you make a purchase from us. Our strip profiles are corrosion-free and have a long life, even in demanding and corrosive conditions.

Handrail profiles
Handrail profiles

With our GRP handrail profiles you get a number of unique advantages in one product namely high strength, low weight as well as corrosion and chemical resistance. This makes our GRP handrail profiles a cost-efficient alternative to traditional materials, such as steel, aluminium and timber handrail, and are often used to ensure a safe passage for railing, stairs, staircase, bridges, walkways and platforms.

Use fiberglass profiles for clever construction

Our fiberglass profiles combine several unique benefits that are not found in other, traditional materials:

  • Low weight
  • Great strength
  • Corrosion free
  • Chemical resistance
  • Minimal maintenance
  • Electrical insulation
  • Easy to work with
  • Non-organic and sustainable building material
  • Thermally insulating
  • CE marked GRP profiles

All these advantages combined into a single GRP material gives you a cost-effective alternative to concrete, steel, timber and aluminium. Here you can find an overview of the 10 most important advantages.

The lightness, strength and durability of glass fiber reinforced polymers (GFRP) allow you to create intelligent end solutions. Our fiberglass profiles will give you the same great strength as steel, but at only a quarter of the density. This allows great weight savings with the GFRP components resulting in a lighter design and a lower total weight for the finished solution.

As a general rule, this will result in savings on the installation costs in terms of special machinery, personnel and assembly time, which can affect other operations.

Why you should consider glass fiber

GRP profiles from Fiberline are corrosion-free and make for a cost-effective alternative to concrete, timber, steel or aluminium. This means that the profiles have a long functional life which makes it possible to avoid the need for costly replacements due to rust or deterioration.

With our fiberglass composite profiles you get no or only minimal maintenance. This results in lower costs over the lifetime of the product. Fiberline’s composite beams and profiles are extremely durable, even in harsh weather conditions and when exposed to corrosive conditions. Usually, they do not require any additional coating following production. Visit our download area for more information.

Should you choose FRP or GRP-profiles?

FRP (Fiber reinforced polymers) and GRP (Glass fiber reinforced polymers) are often used as synonyms referring to the same composite material. At Fiberline, our GRP-profiles are produced with material properties tailored to specific purposes.

Comparing both FRP-profiles and GRP-profiles with steel and wood show some interesting possibilities for your next sustainable construction whether it is for building, industry or offshore. See the product comparison here.

The large number of standard geometries that we offer you, such as U-profiles, I-profiles and square tubes, are widely used in a great many industries and sectors. Among other things, you can currently find them used in offshore installations, in the railway sector, and for swimming pools, wastewater treatment plants, cooling towers and infrastructure.

We deliver high quality fibreglass solutions

Fiberline fiberglass profiles are CE-certified, which is your guarantee of high and consistent quality every time you make a purchase from us. Among other things, CE marking on our fibreglass profiles means that both internal and external, the properties of our profiles are being constantly monitored and tested and that we can ensure traceability from raw materials through to your end products.

One of Fiberline’s distinguishing features is our production process, which is called pultrusion. This process involves pulling fibres through an enclosed tool where they acquire their very special properties. In addition, the quality also remains consistently high, because it is a continuous process.

Frequently asked questions about fibreglass profiles

How do I dispose of fibreglass waste?

In the case of smaller quantities of fibreglass, there is no one recycling method yet. Therefore, the profiles that are no longer of use must be delivered to recycling stations, where they often are categorized as ”small flammables”. Consult your local recycling site to find out about the specific conditions. In the case of larger quantities of fibreglass, the material can be reused as a raw material and substitute fuel in cement production. Learn more about fibreglass here.

How to sort fibreglass waste properly?

As there is no one method of recycling fibreglass yet, the profiles that are no longer
of use must be delivered to local recycling stations, where they are often categorized as ”small flammables”. Consult your local recycling site for specifics. In the case of larger quantities of fibreglass, there are some companies which purchase fibreglass material and use it for different processes, e.g. in cement production. Read more about fibreglass here.

Can fibreglass waste be reused?

Fibreglass profiles have a very long useful life and generally shall not be reused. Currently, there is no one recycling method for smaller quantities of fibreglass. Therefore, you should always consult your local recycling site. With regard to larger quantities, the material can, among other approaches, be reused as a raw material and substitute fuel in cement production or, alternatively, as a subassembly in new constructions.
