1、 Classification

According to different processing methods, steel profiles can be divided into three types: cold drawn profiles, hot-rolled profiles, and cold-rolled profiles.

1. Cold drawn profiles

Cold drawn profiles are formed by cold drawing rod-shaped steel, including round steel, hexagonal steel, square steel, flat steel, channel steel, irregular steel, etc.

2. Hot rolled profiles

Hot rolled profiles are formed by heating steel billets to a certain temperature and undergoing certain processing techniques, including angle steel, I-beams, H-beams, etc.

3. Cold rolled profiles

Cold rolled profiles are formed by cold rolling deformation, usually carried out at room temperature, including cold-formed thin-walled steel profiles, lightweight steel keels, etc.

2、 Common types of steel profiles

1. Round steel

Round steel is one of the most common cold drawn profiles, with high strength and toughness, widely used in fields such as machinery and construction.

2. H-shaped steel

H-beam is a type of hot-rolled profile with an "H" - shaped cross-section, which has good bending and load-bearing capacity and is commonly used in structures such as buildings and bridges.

3. Angle steel

Angle steel is a hot-rolled profile with good tensile and torsional strength, commonly used in fields such as building support and manufacturing machinery and equipment.

4. I-beams

I-beam is a hot-rolled profile with high strength and stability, widely used in fields such as building structures and bridges.

5. Channel steel

Channel steel is a type of cold drawn profile with a "U" - shaped cross-section, which has good load-bearing performance and is commonly used in fields such as building structures and manufacturing machinery.

6. Square steel

Square steel is a type of cold drawn profile with a square cross-section, which has high strength and durability, and is commonly used in fields such as building structures and mechanical components.

Summary:

Steel profiles are a widely used material that, through different processing methods, has formed a rich variety of profile types. In different fields, selecting appropriate steel profiles can improve the load-bearing capacity and durability of materials, providing reliable guarantees for the successful implementation of projects.
