Compatible with O.D. 48.3 mm.
Hot Dipped galvanised finish.
Drop forged to ensure strength and reliability.
Option for customisation.
Conform to BS 1139 EN 74 and AS 1576 standards.

Material and Finish Options

Material: Q235 carbon steel for optimum tensile strength and toughness.

Surface Treatments:

Hot-Dip Galvanized (HDG) for long-lasting corrosion resistance in harsh environments.
Electro-Galvanized (Zinc-Plated) for a smooth finish and indoor/outdoor versatility.

These finishes help extend the life cycle of the couplers, even in high-humidity or offshore construction conditions.
