RRF Purlin Bracket Right 290x2mm Hot-Dip Galvanized Steel 50pcs Fast ​833381

Description

The Fast RRF purlin bracket (right-hand version, 290x2 mm) is a specialized construction connector designed to create strong, reliable, and perpendicular joints within load-bearing timber structures. It is specifically engineered to anchor intersecting timber members—most notably where purlins meet underlying primary beams. Thanks to its well-considered geometry and comprehensive hole pattern, the bracket provides a uniform, robust grip that effectively resists movement caused by wind loads, snow pressure, and other mechanical stresses acting on the roof’s structural framework.

Its asymmetrical design, featuring two offset flanges, is tailored for easy installation on the right-hand side of a beam. This ensures the bracket fits snugly against the timber surfaces, allowing for a clean, precise attachment without adding unnecessary bulk to the structural frame. The connector is ideally suited for all types of roof trusses, floor joist systems, and timber frameworks that will subsequently be covered by roof underlayment, insulation, or facade materials. It is also well-suited for exposed roof structures, where the connectors can remain visible without compromising the building's function.

Technical properties and material quality

The RRF fixed purlin connector is manufactured from durable sheet steel with a thickness of 2 mm. This substantial material thickness ensures high dimensional stability and torsional rigidity, preventing deformation under load or during the installation of screws or nails.

To provide long-term protection against corrosion and moisture, the sheet steel is hot-dip galvanized. The zinc coating creates a robust barrier against external environmental factors and prevents the formation of rust, making the connector highly suitable for Nordic construction conditions. The hole pattern consists of punched, circular nail holes with a diameter of 5.0 mm, arranged in rows to distribute the load optimally across the wood fibers without causing cracking.

Applications and Structural Solutions

The RRF purlin connector (right-hand version) is used in a variety of contexts within modern timber construction:

• Anchoring purlins to primary beams during the new construction or renovation of roofs
• Joining intersecting joists and beams in floor systems and structural frameworks
• Stabilizing load-bearing structures in agricultural buildings, industrial halls, garages, and storage sheds
• Constructing patio roofs, carports, and pergolas that feature intersecting layers of timber
• Reinforcing structures that will have cladding applied over the load-bearing framework

Installation Instructions and Recommended Fasteners

To achieve full load-bearing capacity and ensure a secure connection, the component must be installed using approved fasteners designed for structural connectors. For the RRF purlin connector, use 4.0 mm anchor nails or 4.8 mm anchor screws. The pre-drilled 5.0 mm holes provide a precise fit for these dimensions, minimizing the risk of play (looseness) and ensuring effective load transfer.

During installation, position the connector flush against the intersecting timber surfaces. Install the fasteners, distributing them evenly across the hole pattern on both flanges, in accordance with the relevant structural drawings and load requirements. The smooth contact surface ensures that the connector sits firmly against the substrate from the very first fastener, which significantly simplifies the installation process.
