Double welded channel steel is a common building material with a wide range of applications and important roles. The following will provide a detailed introduction to the functions of double channel steel from three aspects: material characteristics, application fields, and functions. 1,Material characteristics 1. High strength 2. Good corrosion resistance 3. Easy installation 4. Reusable 2、 Application field 1. Construction field: Double jointed channel steel is often used for structural support and load-bearing parts of buildings. For example, frame structures, roof supports, staircase handrails, etc. used to build buildings. Double welded channel steel has high strength and stability, which can withstand large loads and ensure the structural safety of buildings. 2. Transportation field: Double welded channel steel is widely used in the construction of transportation facilities such as railways, highways, and bridges. For example, used for fixing and supporting railway tracks, road guardrails, beams and columns of bridges, etc. Double welded channel steel has high strength and rigidity, and can withstand vibration and impact during transportation. 3. Mechanical manufacturing field 4. In the field of warehousing and logistics unistrut channel, strut channel, unistrut pipe clamps, unistrut beam clamps, unistrut post base, unistrut fittings,seismic bracing system
