Technical data for GFRP profiles

Chemical and water resistance of structural profiles 
The Chemical and Water Resistance Table below shows resistance performance for three qualities of Fiberline profile in different chemical environments. The values indicate the highest known operational temperatures in °C at which the profiles have displayed good service life in the specific chemical environments. The results have been obtained from either industrial experience or from laboratory tests (ASTM C581) carried out by Fiberline suppliers. Resistance to chemicals and water is dependent on concentration and temperature.

It is possible to use gratings, planks and structural supports in chemical environments specified as NR (Not Recommended) or at higher temperatures than stated, provided the chemical influence is not permanent or concentrated but short-term or weak (such as from fumes or spillage). In contrast to metals, Fiberline structural profiles are not subject to electrolytic corrosion.

Please note that the values stated for chemical resistance are based on profiles with surface veils and with all machined surfaces sealed. All data in the table are supplied in good faith and Fiberline accepts no liability for its accuracy. Fiberline reserves the right to make changes without prior notice.

A special polyester is used for temperatures of 150º to 180º C.

No sparks
Because it contains no metal, the material prevents sparks – an extremely important property when used in proximity to gasses and flammable liquids.

Electromagnetic transparency 
Electromagnetic transparency is an important property that is utilized in numerous ways to avoid reflection of electromagnetic waves.

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.

Corrosion-free

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.

Sustainable

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