What does steel structure cross section L75*5 mean?
Steel structure is mainly made of steel material, and it is one of the main types of building structure. The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
In the steel structure, except the angle steel, there are channel steel, C steel, I-beam, H steel, Fang Gang, fish plate and so on.
The "L" in the drawing of the steel structure refers to the angle steel, the 75 is the angle steel limb width, and the 5 is the angle steel thickness, so the steel structural section L75*5 represents the equilateral steel angle with 75mm 5mm and wall thickness of both sides.
Steel is characterized by high strength, light weight, overall rigidity and deformation ability, so it is suitable for building large span and ultra high and super heavy buildings.
