Sgcc Dx51d Zinc Coated Steel Galvanized Iron Coil Cold Roll Steel

Galvanized steel is a form of standard steel in which the steel is coated in zinc to ensure

enhanced corrosion resistance. This galvanized coating protects the steel substrate from

damage typically caused by moisture or temperature changes.

3 Kinds Different Product Surface

1 Zero Spangle: smooth and uniform, without visible zinc crystallization patterns.

2 Electro-galvanize: smooth, bright, and uniform, with a fine metallic luster and no visible spangles.

3 Regular Spangle: visible zinc crystal patterns with a slightly textured metallic appearance.

distinct, visible zinc crystal patterns with a textured metallic appearance.

Quality Control

Our company introduced testing equipment,for product testing,raw materials,semi-finished products,

finished products.

♦ Mechanical Properties Testing

Room-temperature and high-temperature mechanical tests, Brinell hardness, HRC hardness,

Vickers hardness, micro-hardness, expansion, flattening, cupping, bending, compression.

♦ Metallurgical & Corrosion Analysis

Macrostructure analysis, fracture detection, conductivity/resistance, density, grain size, hydrogen

embrittlement, residual stress, dezincification corrosion, salt spray, annealing.

♦ Dimensional & Surface Measurement

Surface roughness, burr angle, radius, inner and outer diameter measurement.

Ocean Shipping

1) We use cushioning materials between the coil and wall, and tighten everything

with specialized lashing straps.

2) We place non-slip wooden blocks under each coil to prevent any movement during the shipping.

3) It has the waterproof layer inside the package, we also put many desiccants in the container,

to protect the cargo from moisture.

Overview of Galvanzied Steel Coil

♦ Hot-dip galvanizing applies a protective zinc coating to steel or iron sheets to prevent rust.

♦ The process involves acid washing full hard steel, then rolling it through a zinc pot to form a zinc

film on the surface.

♦ This produces hot-dipped galvanized steel sheet in coil (GI) with high corrosion resistance, paintability,

and workability.

♦ Hot-dipped galvanized steel coil is a popular, cost-effective product used across many industries.
