What are the Significant Types of Galvanized Iron Pipe?
Let’s discuss the imperative types of galvanised pipe in Mosul, Iraq, from the perspective of innovation and study why it has become more essential than standard steel pipes and tubes. It will guide you in purchasing the best GI pipes according to your needs and preferences:
1. Hot Dip Galvanized Steel (HDG)
We can deduce from its name that it will be produced using the Dipping of steel in any alloy. However, this is the correct answer because it is made by dipping Steel in Zinc alloy. First, the base metal must be cleaned manually with chemicals. Both provide a good quality bond that can be formed between the zinc coating and the steel. The benefit of this specific process is that it is considered cost-effective and can also be done quickly, even for complicated shapes. Nevertheless, the final galvanization of galvanized pipe Erbil, Iraq, is not the same as the other galvanization processes. Additionally, it is included in galvanization.
Technical Configuration
| Parameter | Specification / Range | Unit | Remarks |
|---|---|---|---|
| Base Material | Mild Steel / Carbon Steel | — | Complies with ASTM A36, IS 2062, etc. |
| Galvanization Method | Hot Dip Galvanizing | — | As per ASTM A123 / ISO 1461 |
| Zinc Coating (Thickness) | 40 – 120 | μm | Depending on exposure and |
| Zinc Coating Mass | 275 – 610 | g/m² | Higher coating for outdoor/industrial use |
| Steel Thickness Range | 1.6 – 25 | mm | Can vary based on the application |
| Tensile Strength | 250 – 550 | MPa | Varies with base steel grade |
| Yield Strength | 240 – 350 | MPa | Based on IS 2062 / ASTM A36 grades |
| Elongation | 20 – 30 | % | Minimum elongation in 50 mm gauge length |
| Hardness (Brinell) | 130 – 180 | HB | Before galvanization |
| Zinc Purity in Coating | ≥ 98.5 | % | Commercial-grade zinc |
| Adhesion of Coating | No flaking, peeling, or cracking | — | Visual inspection as per standards |

| Storage Guidelines | Dry, ventilated area; avoid water traps | — | To prevent white rust |
2. Electrogalvanized Steel (EG or EGI)
One of the most distinctive of these methods, detailed, electrogalvanizing, doesn’t entail immersing the material in a molten tank of zinc. Instead, in a GI pipe in Najaf, Iraq, an electric current is brought into an electrolyte solution applied to the steel, reducing the positively charged zinc ions to zinc metal, which is then plated onto the positively charged steel. Similar to pre-galvanizing, this process is typically performed at the first stage of manufacture.
Technical Configuration
| Parameter | Specification / Description |
|---|---|
| Material | Cold-rolled steel (CR) base with electroplated zinc coating |
| Zinc Coating Method | Electrolytic (electroplating) |
| Coating Thickness | Typically 5–30 g/m² per side (can vary up to 60 g/m² total) |
| Coating Weight | 10–60 g/m² total (Z10 to Z60) |
| Surface Finish | Smooth, uniform, with spangle-free appearance |
| Corrosion Resistance | Moderate (lower than Hot-Dip Galvanized Steel) |
| Thickness Range | 0.3 mm – 3.0 mm |
| Width Range | 600 mm – 1500 mm (varies by manufacturer) |
| Tensile Strength | 270–600 MPa (depending on grade) |
| Yield Strength | 140–420 MPa |
| Elongation | 10% – 40% depending on grade and processing |
| Surface Treatments | Oiled, phosphated, chromated, or non-treated |
| Weldability | Excellent |
| Paintability | Excellent (ideal for automotive and appliance industries) |
| Formability | Very good (suitable for deep drawing and press forming) |
| Applications | Automotive panels, home appliances, HVAC systems, office equipment, electronics, and furniture |
3. Galvannealed Steel
Galvannealed Steel is highly resistant to electrical corrosion and easier to weld than other types of steel. It is ideal for architectural purposes due to its high resistance, more rigid core, and strength. You can utilize it for doors, windows, and frame construction.
Technical Configuration
| Property | Specification / Description |
|---|---|

| Base Steel Grade | Commercial Steel (CS), Drawing Steel (DS), Structural Steel (SS), High Strength Low Alloy (HSLA) |
| Tensile Strength | 270–550 MPa (varies by grade) |
| Yield Strength | 140–340 MPa (varies by grade) |
| Elongation | 20–35% (depending on thickness and steel grade) |
| Surface Appearance | Matte gray, slightly rough texture (ideal for paint adhesion) |
| Weldability | Excellent (better than galvanized due to reduced zinc content at weld interface) |
| Paintability | Superior (thanks to the porous iron-zinc surface for better paint bonding) |
| Corrosion Resistance | Good (not as high as pure galvanized but improves with painting) |
| Formability | Good to Excellent (varies with steel grade and coating weight) |
| Common Standards | ASTM A653, JIS G 3313, EN 10346 |
| Applications | Automotive body panels, appliances, door frames, electrical cabinets, construction parts |
| Available Forms | Sheets, coils |
| Thickness Range | 0.4 mm to 3.0 mm (typical commercial range) |
| Width Range | 600 mm to 1500 mm (varies by manufacturer) |
4. Continuous Galvanizing (CGL)
The reason for a continuous galvanization line is to offer corrosion protection for steel using zinc alloy. Zinc coat thickness controls are extensive, and GI pipe in Baghdad, Iraq, is employed for numerous applications. The primary applications are building materials, automobiles, and electrical appliances. CGL of Steel Plantek has unparalleled functions that are highly rated by customers across the globe.
