Description
Needle Beam Propping is a temporary structural support system used in construction and renovation projects to transfer loads from walls or structures to a stable foundation while openings are created, or structural modifications are made. It is commonly used in underpinning, wall removal, façade retention, and structural alterations, providing safe load distribution to ensure stability.How Steel Needle Beam Propping Works:
- Steel needle beams are inserted horizontally through an opening in the wall or structure to redistribute loads.
- The beams rest on adjustable propping systems (Acrow props, hydraulic jacks, or engineered shoring supports).
- This method allows safe removal or modification of lower structural sections while maintaining upper-level stability
- Temporary support for wall removals and lintel installations
- Load-bearing support during façade retention
- Underpinning and basement excavations
- Propping for bridge and civil infrastructure works
- Structural modifications in commercial and residential renovations
Applications
Features
- Material: High-strength structural steel (typically S355 or equivalent) for maximum durability.
- Beam Sizes: Available in various standard lengths (e.g., 100mm, 150mm, 200mm, and 250mm UB or UC beams), with custom sizes available based on load requirements.
- Load Capacity: Engineered to handle high-load applications in propping, shoring, and falsework systems.
- Corrosion Resistance: Hot dip galvanized or painted for long-term durability in harsh environments.
- Adjustable Support: Used in combination with Acrow props, hydraulic jacks, and shoring systems for controlled load transfer.
- Compliance: Meets AS/NZS 3610, AS/NZS 1576, and structural engineering safety standards.
