Max-Gain Systems, Inc. carries a complete line of fiberglass preformed shapes, including fiberglass round tube, square tube, round solid rod, square solid bar, angle, and channel. Most of our product line is designed to "sleeve" inside adjacent sizes, allowing almost any custom length and wall thickness, while at the same time retaining the ability to be shipped via UPS or FedEx! Be sure to see our fiberglass push-up masts page! We are quite unique in that we sell our wide product line in small (even single piece!) retail quantities, which allows individuals and hobbyists, as well as industry prototyping research personnel to economically try multiple possibilities before buying larger quantities.
