Classification of profiles

1. Classification by cross-section shape

1.1 Hot rolled profiles

Characteristics: Produced by hot rolling process, usually with larger cross-section size and better mechanical properties.

Types:

I-beams (I-beam): used for load-bearing structures with high strength and stability.

H-beam: with larger cross-section and load-bearing capacity, suitable for large buildings and bridges.

Channel steel (U-channel): used for supporting and framing structures.

1.2 Cold rolled sections

Characteristics: produced by cold rolling process, usually with smooth surface and high dimensional accuracy.

Types:

Angles: used for frame structures and bracing with good bending resistance.

Rectangular and square tubes: used for load bearing and structures, suitable for welding and joining.

1.3 Specialized profiles

Characteristics: profiles designed to meet specific needs, usually with unique cross-sectional shapes and features.

Types:

Special profiles: including various non-standard shapes, widely used in automobile, aviation and other industries.

Composite profiles: made of a combination of different materials with multiple properties.

2. Classification by material

Characteristics: mainly made of carbon steel or alloy steel, with good strength and corrosion resistance.

Application: widely used in construction, machinery manufacturing and transportation.

2.2 Aluminum profiles

Features: lightweight, corrosion-resistant, easy to process and molding.

Applications: used in construction, automobile, aviation and electronic products.

2.3 Plastic profiles

Features: mainly made of PVC, PP and other plastics, lightweight and corrosion-resistant.

Applications: widely used in construction, furniture and electrical equipment.

3. Classification by Application

3.1 Construction Profiles

Characteristics: Used for building structure and decoration, requiring high strength and good corrosion resistance.

Types:

Steel beams and columns: used for load-bearing structures.

Aluminum window and door frames: for building appearance and heat insulation.

3.2 Machinery profiles

Characteristics: used in the manufacture of machines and equipment, requiring a certain degree of strength and wear resistance.

Types:

o Drive shafts: for connection and transmission of power.

Brackets and supports: for equipment mounting and fixing.

3.3 Decorative profiles

Characteristics: used for indoor and outdoor decoration, requiring aesthetics and durability.

Type:

Skirting and corner guards: used for interior decoration.

Aluminum alloy curtain wall: used for building facade decoration.

4. Classification by surface treatment

4.1 Hot-dip galvanized profiles

Characteristics: Enhanced corrosion resistance by hot-dip galvanizing treatment.

Application: Widely used in outdoor structures and occasions with high corrosion resistance requirements.

4.2 Sprayed profiles

Features: Surface sprayed with different colors of paint to increase aesthetics and corrosion resistance.

Application: Used for home, building and transportation.

4.3 Anodized Aluminum Profiles

Features: through anodizing treatment, a protective film is formed to enhance corrosion resistance and aesthetics.

Application: Widely used in construction and electronic products.

To summarize

Profiles are categorized in a variety of ways, covering a wide range of standard types based on cross-sectional shape, material, use and surface treatment. When selecting profiles, specific application requirements, environmental conditions and economics should be considered to ensure that the right profile is selected to achieve the best performance results.
