Choosing This Size
At 3.5 inches with a 3/8 inch wall, this is one of the strongest square tubes we list. It is used where a column or main frame member must be stiffer than a 3 inch tube, while staying much lighter than a steel column of similar size.
Frequently Asked Questions
Is 88.9 mm the largest square tube you list?
No. The SQ 101.6 x 101.6 x 6.35 is wider at 4 x 4 in, but it has a thinner 6.35 mm wall. The 88.9 mm tube has the thicker 9.53 mm wall.
Which connection method is used for columns?
Usually bolted FRP angles or base plates with stainless steel bolts. Send us the drawing and we will suggest the detail.
Can it be cut and drilled on site?
Yes, with standard power tools. Wear a dust mask and seal cut edges and holes with resin to protect the fibres.
What length can I order?
The standard stock length is TBA. Tell us the length and quantity you need and we will confirm; we can also cut profiles to size.
