Pultruded carbon fibre box section manufactured using high strength carbon fibre and an epoxy resin matrix for maximum performance. This small, square section profile measures 4mm outside, 2.5mm inside, leaving a 0.75mm wall thickness best suited to lightweight applications such as R/C modelling, UAVs, automation and more.
Being a pultrusion, 100% of the fibres run length-ways down the length of the profile, providing maximum stiffness in this direction.
Sold in a 1m length.

Pultruded 4mm carbon fibre box section manufactured from 100% unidirectional carbon fibre.
The box section has an outer width of 4mm and a wall thickness of 0.75mm leaving an inner width of 2.5mm.
Our micro pultruded 4mm carbon fibre square tubes are only available in 1m (39") lengths.
Typical Uses
This tiny 0.75mm wall thickness box section is recommended for use in UAVs, quad copters/quad rotors, robotics and automation.
Further Information
Pultrusion Explained
Pultrusion is a method of manufacturing continuous lengths of fibre reinforced section (in this case box section) by pulling continuous strands of carbon fibre through resin and a former before curing the resin all in one process.
Pultruded sections feature 100% longitudinal fibre orientation which gives them excellent strength along their length but does make them vulnerable to crushing forces. Care should be taken when employing pultruded section to ensure that the fixing points which transfer the load to the section do so in such a way as to minimise any crush forces and distribute the load as much as possible.

Generally, the pultrusions are used ‘as-is’ and don’t require painting. If you really do need/want to paint the pultrusions then a light key with a fine abrasive paper like a 1200 grit wet and dry paper and a thorough degrease and clean using mild detergent or an alcohol wipe should be all that is needed to prepare the surface for paint.
No these pultrusions are not magnetic.
No, this pultrusion is manufactured from standard modulus fibres.
We do not currently offer a custom cutting service for our tubes and pultrusions. However, they are able to be cut DIY relatively easily as you can see from our tutorial video: How to Cut Carbon Fibre Sheet, Tube and Parts
Unfortunately it is not possible to cut a usable thread into carbon fibre composites. The nature of the material is such that the teeth on a thread would not be able to take any load and would break up either during thread turning or the first attempt at using the thread.
Where it is desirable to have a threaded method of attaching the tube or rod, it is commonplace to fabricate and then bond an aluminium insert into the tube or over the rod end which can then have a thread cut into it.
In simple terms these carbon rods would work with linear bearings in that fashion. The only concern is long term durability as the carbon surface is not quite as hard as aluminium and thus would likely wear quicker in many circumstances. For low usage or low load situations this may well not be a limiting factor.
The HDT of these pultrusions is 80 °C.
Yes absolutely! If done carefully, a hacksaw can be used to cut a pultrusion. Take a look at this VIDEO where we show various methods of cutting carbon fibre.
Many people prefer the natural finish of these carbon products, however if you wish to paint them for your specific application then you can do so. A light key with a fine abrasive paper like a 1200 grit wet and dry paper and a thorough degrease and clean using mild detergent or an alcohol wipe should be all that is needed to prepare the surface for paint.
The Box Section surface finish is the natural finish achieved during the pultrusion process which is smooth and has a low level of sheen. The Box Section does not, at this time, come in any other finish.
