SPHC Galvanized steel plate is a high-quality commercial-grade steel product designed for superior corrosion resistance and excellent formability. The "SPHC" designation refers to its Japanese Industrial Standard (JIS G 3131) classification, meaning "steel plate Hot rolled Commercial use." This product starts as a hot-rolled steel coil (SPHC) which is then cleaned and passed through a molten zinc bath in a continuous hot-dip galvanizing process.

The result is a robust steel sheet with a tightly bonded zinc coating that provides a durable protective barrier against rust and corrosion, making it an ideal and cost-effective material for a wide range of applications.

Key Features & Advantages

Excellent Corrosion Resistance: The zinc coating acts as a sacrificial anode, protecting the underlying steel from oxidation and harsh environmental conditions, significantly extending the product's service life.

Superior Formability and Ductility: The SPHC base material offers good elongation properties, allowing it to be easily pressed, drawn, bent, and formed into complex shapes without cracking, making it perfect for fabrication.

High Surface Quality: The galvanizing process can produce a consistent, spangle-free (minimized spangle) or regular spangle finish, providing a uniform and aesthetically pleasing surface suitable for painting or powder coating.

Strong Coating Adhesion: The hot-dip process ensures a metallurgical bond between the zinc coating and the steel substrate, preventing peeling or flaking during forming and fabrication.

Economical and Versatile: It offers an outstanding balance between performance, longevity, and cost, providing great value for numerous industrial and commercial uses.

Common Applications

SPHC Galvanized Steel Plate is widely used across industries due to its versatility:

Automotive Industry: Interior structural parts, brackets, shields, and non-critical body panels.

Construction & Building: Roofing, wall cladding, ceiling panels, ductwork, and structural frames.

Household Appliances: Cabinet housings for air conditioners, washing machines, refrigerators, and electrical enclosures.

General Manufacturing: Storage shelves, switch boxes, agricultural equipment, and furniture frames.

Other Industries: Signage, electrical conduits, and various fabricated metal products.
