Square fiberglass tube is made by the pultrusion process. Fiberglass unidirectional roving (for maximum strength) with a veil mat, pulled via hydraulics through a bath of resin and pigment. Heated and cured. Our stock lengths are the perfect sizes to ship via standard parcel carriers like FedEx and Post. 8 foot long lengths fit under the oversize 3 shipping mark. Oversize 3 goods (anything over 96.02 inches) will all ship at freight rates which start at $120 and rise from there making our lengths of tube perfect for prototyping, hobbyist, etc…
