Characteristics and Differences of Color-Coated Sheets SPCC, SECC, SGCC, SPHC

Color-coated sheets, with designations such as SPCC, SECC, SGCC, and SPHC, exhibit distinct characteristics and differences. Let’s delve into each type:

1. SPCC:

  • SPCC is a grade for cold-rolled sheets, equivalent to DC01 and ST12.
  • It is commonly used for cold plates.

2. SECC:

  • SECC is a deep-drawing-grade cold-rolled sheet, equivalent to DC03, DC04, and ST14.
  • Widely used in automotive applications, body panels, radios, fans, air filters, filters, fuel tanks, household appliances, and office machines.

3. SGCC:

  • SGCC is a common grade for galvanized and color-coated sheets, equivalent to DX51D.
  • Applied in general galvanized and color-coated sheet applications.

4. SPHC:

  • SPHC is the grade for pickled sheets, equivalent to the national standard 08AL.
  • Primarily used in pickled sheet applications.

I. What Material is SECC?

1. SECC Material:

  • SECC is a type of stamped material, featuring a zinc coating on the surface of cold-rolled sheets.
  • Common thickness ranges from 0.4 to 3.2mm.
  • Applicable grades include SECC (originally SPCC), SECD (originally SPCD), and SECE (originally SPCE).
  • Used in automotive, body panels, radios, fans, air filters, filters, fuel tanks, household appliances, and office machines.

2. Applications of SECC:

  • Building applications: Doors, wall partitions, and keels.
  • Machinery production: Agricultural machinery, industrial robots.
  • Cleanroom industry: Interior wall decoration for operating rooms.
  • Can be used in conjunction with appliances, oil tanks, motor covers, and steel furniture bases.

II. Advantages of SECC Material:

1. Material Composition:

  • SECC’s base material is generally cold-rolled steel coil.
  • Through processes like degreasing, pickling, and electroplating, SECC becomes an electroplated zinc product.
  • Combines mechanical properties and processing characteristics of cold-rolled steel with superior corrosion resistance and decorative appearance.

2. Significance in Daily Life:

  • SECC plays a significant role in our daily lives, particularly in electronic products, home appliances, and furniture.
  • Widely used in computer cases, demonstrating its importance in our daily lives.

I. What is SGCC Material?

1. SGCC Material:

  • SGCC is essentially hot-dip galvanized thin steel plate.
  • The manufacturing process involves immersing cleaned iron components in a zinc bath to create an alloy film.
  • Offers advantages such as rust resistance, corrosion resistance, strong weather resistance, and easy processing.
  • Provides an aesthetically pleasing appearance.

2. Types of Hot-Dip Galvanized Thin Steel Plates:

  • Continuous galvanizing process: Steel is continuously melted and immersed in a zinc bath.
  • Creates a uniform zinc coating on the surface.
  • Continuous production method for hot-dip galvanized thin steel plates.
  • Galvanized steel plates: Heated and immersed in molten zinc, forming an alloy film.
  • The appearance is attractive, and processing is easy.
  • Exhibits excellent adhesion and welding properties for coatings.
  • Electroplated galvanized steel plates: Processing is favorable for manufacturing.
  • However, the coating is thinner, and corrosion resistance is lower than hot-dip galvanized plates.
  • Single-sided galvanized steel plates: Better adaptability for welding, painting, rust prevention, and processing than double-sided galvanized plates.
  • Alloyed and composite galvanized steel plates: Utilize zinc and other metals to create alloys or composite coatings.

In Summary

The distinct properties of SPCC, SECC, SGCC, and SPHC make each type suitable for specific applications. The choice depends on factors such as corrosion resistance, processing characteristics, and intended use, emphasizing the importance of selecting the most suitable material for various applications.
