Galvanized Steel - GI , GP and GA
Galvanized steel products undergo thorough cleansing and heat treatment of rolled coils prior to immersion in a bath of molten zinc. Through this process, the coils are plated with zinc only (GI), zinc and iron (GA) or zinc, aluminium and magnesium (PosMAC – POSCOs’ Patent and Trademark Brand).
Galvanized steel is a durable, rust-resistant material with a silver-grey finish. Its protective zinc coating makes it ideal for outdoor use, and it can be left unpainted or decorated. It is cost-effective and low maintenance, perfect for construction and industrial projects.
We deliver a wide range of galvanized steel products according to customer specifications and needs in terms of plating, quantity, lubrication and post-treatment. With good resistance to corrosion, formability, weldability, printability and other useful features, galvanized steel is increasingly used in many areas including civil engineering, architecture and automotives industries.

Hot-Dip Galvanization
- Hot-dip galvanization is a process that is used to protect steel and other metal products from corrosion and rust. This process involves dipping the metal into a bath of molten zinc, which coats the surface of the metal and creates a protective barrier. The hot-dip galvanization process is commonly used in a wide range of industries, including construction, automotive manufacturing, and electrical engineering, among others.
- Increases corrosion resistance
- Prevents Rusting
GalvAnnealed Steel
GalvAnnealed Steel is a type of steel that is well-known for its durable and long-lasting properties. It is considered a hybrid product as it combines the benefits of both galvanized steel and annealed steel.
The galvanizing process adds an extra layer of protection to the steel by coating it with a layer of zinc, which helps to prevent corrosion and rust from forming. The annealing process strengthens the steel by heating and cooling it to a specific temperature, which improves its ductility and toughness.
These unique properties make GalvAnnealed Steel ideal for a variety of industrial and commercial applications, including automotive manufacturing, construction, and transportation. Additionally, it is a cost-effective and eco-friendly option, as it is widely available and easily recyclable. If you are looking for a high-quality, durable steel product, GalvAnnealed Steel is an excellent choice.
Annealing + Galvanization = GalvAnnealed
- Better welding performance than GI
- Better paint adhesion than GI Steel
GI Spangle
A spangle is a visible aesthetic feature of crystallites on the surface of a galvanized steel sheet. The spangle appears as either a snowflake or a six-pointed star pattern
- High Spangle – Grainy finish (above picture)
- Zero Spangle – Smooth Finish
- Achieved by regulating the cool down time post hot-dip

GI/GI(H)
Galvanization of cold-rolled plates (GI) and hot-rolled plates (GI(H)) involves immersing them in molten zinc, which solidifies to form a surface with finely suppressed crystallization. This process ensures excellent plating reliability, rust inhibition, and cost-effectiveness, making it indispensable across various industries.

GA/GA(H)
GA is applied to the surface of cold-rolled steel, while GA(H) is applied to hot-rolled steel surfaces. Upon heating, the base plate and zinc undergo diffusion to create a durable alloy coating containing 9 to 13 percent iron. Known for its excellent weldability, this coating is widely utilized in automotive parts and beyond.

Galvanized Steel - Post Treatment
The post-treatment process includes applying a protective film to zinc or Zn-Mg-Al coated steel plates, extending their lifespan by safeguarding the substrate steel. This enhances corrosion resistance and other properties such as resistance to contamination and fingerprints, making it highly suitable for a wide range of applications.
