Pultruded Carbon Fiber Square Tubes - 4x4 to 8x8 Industrial Grade

• Pultruded carbon fiber square tubes, ranging from 4x4 to 8x8 inches, are industrial-grade structural components engineered for heavy-duty load-bearing applications. Pultrusion—a continuous manufacturing process—aligns carbon fibers parallel to the tube length, maximizing axial strength and stiffness, making them ideal for columns, support beams, and machinery frames. Unlike traditional steel square tubes, they offer 70% weight reduction while maintaining comparable compressive strength, easing installation and reducing structural stress. The 4x4 inch tubes suit light industrial frames (e.g., conveyor systems), while 8x8 inch tubes handle heavy loads in construction shoring or offshore platform supports. Constructed from high-tensile carbon fiber and vinyl ester resin (for chemical resistance), they resist corrosion from acids, saltwater, and industrial solvents, outperforming steel in harsh environments. With consistent cross-sectional dimensions (±0.2mm tolerance) and smooth surfaces,
