What Is Heavy Steel Plate?

What Is Heavy Steel Plate?

Heavy steel plate refers to any steel plate that is 6mm thick or more. These plates come in a wide variety of grades and are widely used across construction, mining, energy, and automotive industries. Heavy steel plates are most commonly applied in structural and building projects, where strength and stability are essential.

Common Grades of Heavy Steel Plate

Cheongfuli offers a full range of heavy plate grades, including:

• Structural steel: SS400, S235JR, S355JR, Q235

• Wear-resistant steel: NM400, NM450, NM500

• Weathering steel: A588 GrA/B, A709HPS50W/70W

• Pressure vessel steel: A516 Gr70, A537 Cl1/Cl2

• Shipbuilding steel: ABS-A, AH32, AH36, DH36, EH36, E40

• Offshore steel: API 2W, API 2H

Each grade is alloyed to enhance strength, hardness, and durability, making these plates ideal for heavy-duty structural and industrial use.

Material Testing of Heavy Plate

As plate thickness increases, the risk of internal laminations—tiny defects formed during the rolling process—also rises. These flaws can reduce a plate’s structural integrity if left undetected.

To ensure quality, buyers often request Ultrasonic Testing (UT). This advanced inspection uses high-frequency sound waves to detect hidden layers, folds, or trapped gases, guaranteeing that your heavy steel plate is structurally sound and safe for demanding applications.
