Electrogalvanized Steel Sheet SECC DX51D with 0.12-2.5mm Thickness and Color Coated Surface

Product Description

Electrogalvanized Steel Sheet Secc Dx51d

Galvanized sheets are steel sheets coated with zinc to prevent rust, primarily categorized by production method into Hot-Dip Galvanized (HDG), Electro-Galvanized (EG), and Galvannealed. They are further classified by coating weight (G30-G235) and surface finish, with applications ranging from automotive components to structural, high-corrosion, and aesthetic uses.

Key Types of Galvanized Sheets

Hot-Dip Galvanized (HDG) Sheet: The most common type, created by dipping steel in molten zinc, providing high durability.
Electro-Galvanized (EG) Sheet: Produced by electroplating, this results in a thinner, smoother, and more uniform zinc layer, often used for automotive components and in indoor applications needing aesthetic finishes.
Galvannealed Sheet: A hybrid process combining hot-dip galvanizing and annealing to create a matte gray zinc-iron alloy coating, which offers superior paint adhesion and weldability.
Galvalume / Alu-Zinc Sheet: Coated with an alloy typically consisting of 55% aluminum, 43.4% zinc, and 1.6% silicon, providing improved corrosion resistance and durability compared to pure zinc coating.
Pre-Painted Galvanized Sheet (PPGI): Galvanized steel that has been painted with organic coatings (such as PE, PVDF) for added aesthetics and corrosion protection.

Frequently Asked Questions

Q1: What does "DX51D" stand for?

According to the EN 10346 standard:

D: Flat steel for cold forming.
X: The base metal state is not specified (usually cold-rolled).
51: Steel grade sequence number (indicates commercial quality).
D: Hot-dip galvanized (coated with a zinc layer).

Q2: What is the difference between DX51D+Z and DX51D+AZ?

The difference lies in the coating composition:

+Z (Galvanized): 99% pure zinc coating. Offers excellent sacrificial protection.
+AZ (Galvalume): 55% Aluminum, 43.4% Zinc, and 1.6% Silicon. It offers superior heat resistance and 2-6x the corrosion resistance of pure zinc in most environments.

Q3: What are the standard dimensions for DX51D coils?

Typically, the thickness ranges from 0.12mm to 4.0mm, and the width ranges from 600mm to 1500mm (common widths are 914mm, 1000mm, 1219mm, and 1250mm).
