Working with FRP

- How do I paint fibreglass?

Fibreglass is easy to paint, but the process depends on both the solution in question and the desired finish. Here are our recommendations when it comes to painting fibreglass.

- How do I glue fibreglass?

Gluing fibreglass depends on the type of job involved, but it is usually very easy to do. Watch our How to video about gluing here

- How do I cut and saw fibreglass?

Working with fibreglass is very much like working with timber. A circular saw or jigsaw is ideal for ensuring a straight cut. Diamond-coated blades should be used for larger batches. The diamonds make the blade last longer. You can read more about cutting speeds and watch our how-to video to see how easy it is here in our How to video

- How do I drill into fibreglass?

Drilling into the profiles is relatively straightforward. An ordinary metal drill bit should be used to drill individual holes or small numbers of holes.
The use of a special drill bit is recommended for larger numbers of holes. This will ensure that the hole rims are clean and free from burring. A spoon bit and centre bit can be used to drill large holes. You can find lots of advice about drilling here

- How do I insert bolts and screws into fibreglass?

It really depends on what it is that you need to mount or fit together. We have provided the example of a square tube, which we recommend should be fitted using a sleeve, insert or washer. It is the same idea for many other types of mounting, but if you are in any doubt you can always get in touch for technical advice. See how to mount a square tube on a stair in our video here

- How do I mount fibreglass?

Mounting naturally depends on the type of structure that is being assembled. We have provided an example of how to mount a square tube onto a staircase. Watch the video here

- How do I grind and deburr fibreglass?

Our fibreglass profiles can be ground using sandpaper. For larger tasks, however, we recommend using a belt sander.

- How do I turn fibreglass?

For turning, we recommend using carbide plates with speeds of up to 400 m per minute. A top rake of 10–15° will yield the best results. The feed rate and cutting depth will depend on the machine used, but is typically between 0.05 and 0.5 mm/rev. Depending on the machine and the set-up, the depth of cut can be up to 10 mm. Using rounded tool bits and air or liquid cooling results in the best surface finish. Turning can also be done with a rotating diamond milling cutter in the tool holder.

- How do I mill fibreglass?

A diamond milling machine should be used for milling. We recommend a top rake of between 5° and 15° and speeds of up to 1,000 m per minute for the best results.

 Feeding can be up to 0.5 mm/rev. Too heavy feeding will cause unwanted heating of the surface and gives less satisfactory results.

- What about punching, threading and waterjet cutting?

Punching, threading and waterjet cutting can be used when working with fibreglass. However, it depends very much on the type of work involved and the machinery available. Please refer to our recommendations or contact us if you would like further details.

- How do I work with a HD Plank?

Glass-fibre reinforced polyester (GFRP) is a hard material, but it is as easy and fast to work with as timber. We recommend that you use diamond-coated tools, such as cutting blades. You can now buy diamond-coated blades at any hardware shop. Watch our how to video here

- How do I install HD and MD Planks?

Our planks can be bolted, pinned or glued to the substructure. Fiberline has developed special fittings that make assembly easier and faster. All of these fittings are made of acid-resistant steel. Please give us a call if you are in any doubt about how to install your particular solution.

- What is fibreglass?

Fibreglass is a composite material that consists of glass fibres and hard plastic. Fibreglass solutions can be made in many different ways, but here at Fiberline we use pultrusion, which is one of our distinguishing features. Read more here

- What are fibreglass profiles most suitable for?

ibreglass profiles have many advantages, so they are used in and for a number of different industries and applications. We have gathered some of the most usual applications here

- What does MD stand for?

MD stands for 'medium duty' and is a term used to describe our planks. Our MD planks are suitable for projects where the design load is not as high. These planks are 20% lighter than our HD planks, which can bear heavier loads.

- What does HD stand for?

HD stands for 'heavy duty' and is a term used to describe our planks. What it means concretely is that HD planks are suitable for heavy pedestrian traffic or long spans. Fiberline’s product range also includes an MD plank, which is 20% lighter and suitable for projects where the design load is not as high.

- How do I repair minor damages?

If our fibreglass profiles are scratched or cut, you do not necessarily need to worry about their mechanical properties. Find out more about minor damages here

- How do i repair mayor damages?

n the case of major damage where the fibres are clearly exposed, the profile’s properties may be affected. In such cases, we recommend replacing the profile. Find out more here

- How do I manage fibreglass waste?

There is not yet any way of re-using small quantities of fibreglass. Profiles that can no longer be used must therefore be taken to a recycling centre, where they will usually be classed as small, combustible waste. Ask your local recycling centre about the rules that apply.

For larger quantities of fibreglass, the material can be re-used by incorporating it into cement production as a raw material or substitute fuel.
