Galvanized Butt-Weld Fittings Manufacturer, Exporter & Supplier

Dipti Metal Industries is a leading manufacturer, exporter, and supplier of Hot-Dip Galvanized Butt-Weld Fittings, supplying to industries worldwide. Our galvanized fittings are produced in compliance with international standards and are designed to offer long-term corrosion resistance in harsh environments such as oil & gas, marine, chemical, power plants, and water treatment systems.

We specialize in Elbows, Tees, Reducers, Caps, Stub Ends, Crosses, and Special Butt-Weld Fittings, all available with Hot-Dip Galvanized (HDG) coatings. These fittings not only provide durability but also meet the demands of modern infrastructure, ensuring safety, reliability, and extended service life.

What are Galvanized Butt-Weld Fittings?

Galvanized Butt-Weld Fittings are carbon steel or alloy steel fittings that undergo Hot-Dip Galvanizing (HDG), where they are immersed in molten zinc at 450°C. This process forms a zinc-iron alloy layer that acts as a protective barrier, ensuring resistance to corrosion, rust, and atmospheric damage.

These fittings are widely used in piping systems, fluid transmission lines, and structural applications where enhanced corrosion protection is required.

Hot-Dip Galvanized Specifications

• Process: Immersion in molten zinc at ~450°C (840°F)

• Coating Layers: Zinc-iron alloy layers with pure zinc top layer

• Average Coating Thickness: 70–100 µm (up to 125 µm for heavy-duty applications)

• Minimum Coating Weight: 610 g/m² (as per ASTM A123 for >6mm steel)
