Key Technical Specifications

Material	Mostly malleable cast iron or ductile iron. Specialized versions for aluminum scaffolding may be made from cast aluminum.
Compatible Tube Size	Suitable for standard scaffolding tubes with an outer diameter of 48.3 mm (or 48.6 mm).
Weight	Generally lighter than heavy-duty forged couplers, ranging from 0.75 kg to 1.1 kg.
Standards Compliance	High-quality casted couplers can meet EN74 and BS1139 requirements, though they are mostly used in light-duty or non-structural applications.
Surface Treatment	Commonly electro-galvanized or painted for corrosion resistance.

Usage Considerations

Brittleness Risk

Cast iron is comparatively more brittle than forged steel. Under heavy load or sudden impact, casted couplers may crack rather than deform, potentially leading to sudden failure.

Recommended Applications

Ideal for temporary scaffolding, lightweight staging, and interior maintenance work where total loads are low and design flexibility (e.g., compatibility with various tube sizes) is required.

Maintenance Requirements

Regular inspection for cracks and rust is essential. Due to the nature of the casting process, internal micro-voids may exist, increasing the importance of routine checks.

Product Information

Benefits of Casted Fixed Couplers

Casted fixed couplers, also referred to as cast iron or ductile iron swivel couplers, are scaffolding fittings produced by pouring molten metal into preformed molds.

Although drop-forged couplers remain the industry standard for high-strength structural applications, casted couplers provide a practical alternative with greater design flexibility and distinct material characteristics.
