H-shaped fiberglass beam is an economical cross-section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of H-shaped fiberglass beam are arranged at right angles, H-shaped fiberglass beam has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used.
An economical cross-section profile with a cross-section shape similar to the capital Latin letter H, also called universal fiberglass beam beam, wide edge (edge) I-beam or parallel flange I-beam. The cross section of H-shaped fiberglass beam usually includes two parts: web and flange plate, also known as waist and edge.
The inner and outer sides of the flanges of H-shaped fiberglass beam are parallel or close to parallel, and the flange ends are at right angles, hence the name parallel flange I-beam. The web thickness of H-shaped fiberglass beam is smaller than that of ordinary I-beams with the same web height, and the flange width is larger than that of ordinary I-beams with the same web height, so it is also called wide-edge I-beam. Determined by its shape, the section modulus, moment of inertia and corresponding strength of H-shaped fiberglass beam are significantly better than ordinary I-beams of the same unit weight.
