Galvanized angle steel is a specific type of galvanized steel. Galvanized steel is a steel material that has been galvanized. Galvanizing is a technology that coats the surface of steel with a layer of zinc. This layer of zinc can prevent the steel material from corrosion.
Galvanized steel angles are an important building block in the construction and engineering fields, known for their strength and durability. Their L-shaped profile makes them a fundamental component in many applications, from transmission towers to everyday racking solutions.
Q235B is a carbon structural steel with a chemical composition of carbon (C) ≤ 0.22%, manganese (Mn) ≤ 1.4%, silicon (Si) ≤ 0.35%, etc. In the national standard GB700-88, Q235B material is often subjected to temperature shock tests, V-notch, and carbon content between 0.14 - 0.22﹪.
After hot-dip galvanizing, a zinc layer is formed on the surface of the steel. This zinc layer can effectively isolate the steel from the external environment, prevent oxygen, moisture, etc. from corroding the steel, and greatly extend the service life of the angle steel. It is especially suitable for humid and corrosive environments, such as seaside buildings, chemical plants, etc.
The galvanizing treatment is an important feature of these angle steels. The galvanizing layer can provide good anti-corrosion protection for the angle steels and extend the service life of the angle steels in various environments, especially in humid and corrosive environments. At the same time, the galvanizing layer makes the surface of the angle steels smoother and more beautiful.
American standard H-beam A36 is a carbon structural steel with excellent performance. It is made by adding a certain amount of alloy elements such as silicon, manganese, phosphorus, etc. to ordinary low-carbon steel. Its main component is iron, the carbon content does not exceed 0.2365%, the silicon content is between 0.15% - 0.40%, the manganese content is between 0.30% - 0.60%, and the phosphorus content is between 0.035% - 0.045%. The reasonable ratio of these elements makes A36 have excellent performance in strength, hardness and toughness. It also has excellent plasticity and weldability.
