Quality Check


Quality policy

At Fiberline, quality is at the heart of our business and everything we do. We have described this in more detail in our quality policy, which we strive to live up to every single day.

A professional partner 

Our quality system is designed to ensure that our customers think of us as a professional business partner that provides composite solutions of the very highest quality. We measure customer satisfaction through close contact with our customers and by performing an annual survey. We are therefore able to react quickly to significant deviations and keep our focus on constantly improving. Among other things, we use the 8D Problem-Solving Process, with the target of giving our customers an initial response within 48 hours.

Close collaboration 

We want to work closely with our customers to develop new solutions. We use the APQP process in our development work; it is a systematic, structured approach. We do this in order to achieve the agreed values for quality and material properties. To supplement this, we also use elements from the automotive industry in order to ensure process stability and thus reduce errors; specifically, these elements are PPAP, FMEA, MSA and SPC. We use APQP4WIND for our work with the wind industry.

Anchored in our management system

Our quality policy sets out our commitment to continually develop and streamline our management system and business processes with the clear aim of creating added value for our customers. Among other things, we do this by having a complete overview of our quality costs so that we can continuously reduce them. In addition to this, we continuously monitor the process parameters for our pultrusion lines, in order to ensure a high level of capability. Finally, all product batches are inspected in accordance with our instructions before they are dispatched.

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.
