Fiberglass Tube(include fiberglass round tube,fiberglass square tube and fiberglass rectangular tube),glass tubing glass tubing are made through pultrusion process. During the pultrusion process, the raw materials are pulled through a heated steel forming die using a continuous pulling device.glass tubing are made of different resins reinforced with fiberglass by pultrusion technology.glass tubing are widely used in many areas. Fearures of glass tubing: ♦Corrosion Resistant ♦ Low Conductivity - Thermally and Electrically ♦ Non-Magnetic - Electromagnetic Transparency ♦ Light Weight and High Strength ♦ Dimensional Stability ♦ Low Maintenance
