Getting to Know Various Metal Plate Materials

Mild steel is a low-carbon steel material—with a carbon content of no more than 2%—which makes it less brittle and easy to form. These characteristics make mild steel an ideal choice for a wide range of industrial applications, from building structures and automotive components to metal furniture.

Advantages of Mild Steel

In addition to its strength and durability, mild steel is also known for its flexibility during the forming process.
Some of its main advantages include:

• Strong and resistant to breaking, making it suitable for building frameworks.

• Easy to form and weld, thanks to its low carbon content.

• Versatile, can be used for a variety of products such as façades, door ornaments, room partitions, and vehicle frames.

With these characteristics, it’s no surprise that mild steel plates have become a primary material across many industrial sectors.

Types of Mild Steel Metal Plates

Mild steel metal plates come in several variants, each with unique characteristics and functions.
Here are four common types used in the manufacturing industry:

1. SECC (Steel Electrogalvanized Cold-rolled Commercial Quality)

SECC is a high-quality galvanized steel plate often used for computer casings or electronic components.
Its main advantage lies in ease of processing—it requires no special treatments such as bending, welding, or shallow stamping.

2. SPHC (Steel Plate Hot Rolled Commercial)

Also known as black steel plate, SPHC is a hot-rolled carbon steel with a distinct dark color.
This material meets the JIS G 3131 (Japan) standard and is often used in building construction as a structural joint due to its high strength.

3. SPHC–PO (Pickled and Oiled)

SPHC–PO is a variant of SPHC coated with protective oil (Pickle Oil) to prevent rust and stains.
Its main advantage is oxidation resistance and easier welding—no cleaning required beforehand.
This material is usually light gray in color, unlike the darker SPHC, and is widely used for automotive chassis and frame structures.

4. SPCC (Steel Plate Cold Rolled Coiled)

SPCC is a cold-rolled steel plate with a smooth surface ranging from light gray to white.
It offers high flexibility, making it ideal for stamping processes in truck bodies, car parts, or other automotive components.
SPCC is also commonly used for electrical appliances, household products, and office equipment.
