The choice of resin largely depends on where the gratings are to be used. Our two most used materials are Ortho polyester and Iso polyester.
Ortho polyester: Moderate corrosion resistance without fire-retardant substances. Suitable for contact with salt water and for light industrial use. Read more here 'Ortho' (English)
Iso polyester: Superior corrosion resistance with improved fire-retardant properties. Suitable for environments with aggressive chemicals and high temperatures. The gratings are DNV-approved for use on ships. Read more here Isophthalic Polyester (English)
We also have a limited stock of gratings in Vinyl Ester, which are therefore typically produced on demand. Read more here: Vinyl Ester (English)
The load tables are used to determine the height of the gratings, which depends on e.g. range and deflection requirements.
Here you'll find useful information about our gratings, ready to print out or attach to your project file.
The gratings' appearance (such as gratings with smooth edges) can be of significance to the end customer, and may therefore determine their overall dimensions.
The dimensions of the table can be combined freely in longitudinal(L) and lengthwise(B) directions. Note however the basic dimensions of the chosen grating panel.
Gratings cut to dimensions as listed in the below table have smooth edges (i. e. no "fingers"). Cutting tolerance +2/-5.
The outside grid of whole panels is 3 mm smaller than the inside grid.
Gratings cut to smooth edges, where the inside grid is used, is therefore 3 mm smaller than listed in the table. Allowances were made for this in the cutting tolerances.
Grid size 20 x 20 / 38 x 38 mm:
Grid size 40 x 40 mm:
Grid size 50 x 50 mm:
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.
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.
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.

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.
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.
Fiberline's fibreglass profiles have a significantly lower heat distribution gradient than steel and aluminium, enabling energy-efficient end products.
