Structure Fittings – Double Bend

Double bend fittings for complex directional changes in structural systems.

Structure Fittings Double Bend Overview

Double Bend fittings provide a two-leg change in direction, effectively combining bends to redirect structural tubing in more complex geometry. These fit over matching galvanised tubes and are fixed via grub screws, allowing modular routing of frame members. The catalog uses the same dimensioning as standard bends—DT25, DT30, DT40, DT50—for nominal bore sizes and associated H and L dimensions. Double bends are especially useful when needing to route around obstructions or providing offset parallel paths while maintaining structural continuity.

Design Considerations

Provide sufficient overlapping tube length in each leg.
Check that directional change does not cause interference.
Use bracing or support to handle bending moments.
Useful in tight layouts where two consecutive offsets are needed seamlessly.

Applications

Double Bend fittings are used in structural frameworks where complex or multi-leg turning is needed, such as:

– Routing the support frame around equipment or obstacles with two sequential offset changes

– Creating structural paths with parallel offset segments

– Simplifying multi-leg frame geometries without multiple single bends

– Maintaining load continuity while achieving complex alignment

– Modular re-arrangements of structural paths around plant constraints
