The supporting structure of the bridge adopts I-beams, channel steel, and angle steel, which reduces its own weight and improves the overall stability of the bridge while ensuring structural strength. The cross-sectional shape of I-beams is regular, making it easy to cut, weld, and process, and also convenient to connect with other materials such as concrete. The cross-sectional shape of I-beams is regular, making it easy to cut, weld, and process, and also convenient to connect with other materials such as concrete. Angle steel is commonly used as a connector and supporting component for bridges, which can effectively connect other steel materials such as I-beams, channel steel, etc., forming a stable structural system. I-beams, channel steel, and angle steel have wide application value in bridge engineering. By selecting and combining them reasonably, their advantages can be fully utilized to improve the performance and economy of bridge structures.
