Dx51d Z60 Construction Material GI Steel Coil 1.5mm Galvanized Iron Coil

Dx51d Z60 Construction Material GI Steel Coil 1.5mm Galvanized Iron Coil

Hot dipped galvanizing involves steel into molten zinc pool, creating a protective layer. This

process forms a metallurgical bond between the steel and zinc, acting as a shield against

corrosion.

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.

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.
