Galvanised steel pipe fittings malleable iron four-way corner elbow DN15 DN20 DN25 three-dimensional connection for plumbing and construction applications with corrosion resistance
Galvanised Steel Pipe Fittings: Four-Way Corner Elbows for Plumbing and Construction Systems

These galvanised steel pipe fittings provide essential connection points for various piping applications, from domestic plumbing to industrial installations. Manufactured from malleable iron with a protective galvanised coating, these fittings offer corrosion resistance while maintaining the strength required for secure pipe connections. The four-way corner elbow design enables three-dimensional routing of pipes, allowing for flexible system layouts without requiring multiple separate fittings. Available in three standard diameters to accommodate different flow requirements and pipe specifications.
Features and Construction

The galvanised steel pipe fittings combine practical design with industrial-grade materials for reliable performance in various applications.
Material and Build
Constructed from malleable iron with a galvanised steel coating, these fittings provide corrosion resistance suitable for plumbing systems exposed to moisture. The Grade A manufacturing standards ensure consistent quality across production batches, while the 16 compressive strength rating indicates suitability for standard plumbing pressure requirements. The galvanisation process creates a protective layer that helps prevent rust formation on the iron substrate.
Size and Practical Fit
Available in three standard diameter options: DN15, DN20, and DN25. These correspond to common pipe sizes used in residential and commercial plumbing systems. The 2mm tube thickness provides sufficient wall strength for joining sections of steel piping while maintaining compatibility with standard pipe dimensions. The fittings are designed to accept pipes of matching diameters for secure connections.
Uses and Placement

These four-way corner fittings serve multiple applications across different sectors where pipe systems require directional changes and branch connections.
Event or Professional Use
For professional plumbing installations, these fittings enable complex pipe routing in confined spaces where multiple direction changes are required. The three-dimensional design allows pipes to extend in four directions from a single connection point, reducing the number of fittings needed for branching systems. Suitable for irrigation systems, industrial fluid transport, and mechanical services where steel piping is specified.
Everyday Home Use
In residential applications, these fittings can be used for garden irrigation systems, workshop air lines, or basement plumbing where steel pipe is preferred. The corrosion-resistant galvanised coating makes them suitable for outdoor installations or damp environments where standard iron fittings might corrode. The standard diameters match common pipe sizes used in DIY plumbing projects.
Benefits and Buying Value

These galvanised pipe fittings offer practical advantages for both professional contractors and DIY enthusiasts working with steel piping systems.
Reuse and Low Maintenance
The galvanised coating provides ongoing corrosion protection without requiring additional surface treatments after installation. Unlike painted fittings that might chip or peel over time, the galvanised finish is bonded to the metal substrate. This makes the fittings suitable for long-term installations where periodic maintenance access might be difficult or impractical.
Why Choose This Product
The four-way corner design reduces the need for multiple separate elbows and tee fittings when creating branching pipe systems. Available in three common diameters, these fittings provide flexibility for different project requirements without needing to source from multiple suppliers. The malleable iron construction offers a balance of strength and machinability for secure pipe connections.
