Good Basic Mechanical Properties:
High Strength: Q235 steel itself generally has a yield strength of about 235MPa and a tensile strength ranging from 370 - 500MPa. As the base material of the hot - dipped galvanized I - beam, it can bear a certain load and stress and meet the basic requirements for steel strength in building structures, machinery manufacturing and other fields.
Good Toughness: When subjected to external forces such as impact or vibration, it can absorb energy and is not prone to brittle fracture, which can ensure the safety and stability of the structure under dynamic loads.
Suitable Ductility: It has good ductility and allows for deformation processing to a certain extent, such as bending, stretching and stamping, so it is convenient to manufacture structural members of various shapes and sizes according to actual needs.
Excellent Anti - corrosion Performance:
Zinc - layer Protection: The hot - dipped galvanizing process forms a dense zinc layer on the surface of the I - beam. This zinc layer can effectively isolate the steel from the external environment and prevent oxygen, moisture and other corrosive substances from corroding the I - beam. In corrosive environments such as humid conditions, acid rain and marine areas, it can significantly extend the service life of the I - beam.
Long - term Anti - corrosion: In relatively favorable environments such as suburbs, the standard hot - dipped galvanized anti - rust thickness can last for more than 50 years without repair; in urban areas or near - sea regions and other environments with slightly stronger corrosiveness, the standard hot - dipped galvanized anti - rust layer can also last for 20 years without repair.
Reliable Coating Adhesion:
Metallurgical Bonding: During the hot - dipped galvanizing process, the zinc liquid reacts with the surface of the I - beam to form a metallurgical bond. This bonding method makes the adhesion between the zinc layer and the steel very strong, and it is not easy to fall off or peel off, ensuring long - term use effect.
Good Machinability:
Easy - to - Process: The proportion of hardness and toughness of the steel is moderate. Whether it is cutting, welding or other processing methods, they are relatively easy to operate and can reduce processing costs and construction difficulties.
Customizability: According to different engineering requirements, hot - dipped galvanized I - beams of various specifications, sizes and shapes can be customized to meet the diverse needs of building structures, bridges, machinery manufacturing and other fields.
