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

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

Angle profiles
Angle profiles

The FRP angle profiles have high strength and can advantageously be used for the assembly of stair treads and as brackets for many applications where load-carrying capacity coupled with thermal insulating properties is needed. Furthermore, the FRP angle profile can be used as lateral bracing for constructions.

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.

Tube profiles
Tube profiles

Our fibreglass tube profiles are corrosion-free and weather resistant which ensures a long lifetime even under demanding conditions in industry and construction. These tubes are often used as knee rails for railing solutions.

Kick plate
Kick plate

Our kick plate/toe plate is corrosion and chemical resistant which make it suitable for demanding industrial and offshore environments. Furthermore, the kick plate has a low weight and with easy mounting it forms part of different stair and railing solutions.

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 smart construction

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

  • Low weight
  • High strength
  • Corrosion resistance
  • Chemical resistance - Chemical resistant
  • 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 of our GRP profiles.

Properties of our fibreglass pultruded profiles

The low weight, high strength and durability of our range of GRP pultruded profiles allow you to create intelligent end solutions. Our GRP pultruded profiles will give you the same great strength as steel, but at only a quarter of the density. This allows great weight savings of up to 50% with the GRP profiles resulting in a lighter design and a lower total weight for the finished solution.

As a general rule, our light GRP pultruded profiles will enable savings on the installation costs in terms of minimising special machinery, heavy lifting equipment, transport, personnel and assembly time.

Advantages of GRP pultruded profiles

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

With our fibreglass profiles you get minimal maintenance. This results in lower costs over the lifetime of the GRP profiles and the end product. Fiberline’s fibreglass beams and fibreglass 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 about our GRP profiles.

Should you choose fiberglass and 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 pultruded profiles are produced with material properties tailored to specific purposes. See our range of GRP pultruded profiles here 

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

Typical uses of GRP pultruded profiles

The large number of standard geometries that we offer you, such as U-profiles, I-profiles/i-beams and GRP 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, water treatment works, cooling towers, industrial environments and infrastructure. Learn more about our customers within these industries here 

We also have a number of competitive standard solutions made with our GRP pultruded profiles which makes it easier for you as a customer with us, e.g. pedestrian bridges, stair towers and platforms. Explore all solutions here 

We deliver high quality fibreglass structural profiles

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 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 our structural profiles distinguishing features is our production process, which is called pultrusion process. This production process involves pulling fibres through an enclosed tool where the end products, our GRP pultruded profiles, acquire their very special properties. In addition, the quality also remains consistently high, because it is a continuous process. Learn more about our approach to quality of our GRP pultruded profiles here.

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.
