RRF Purlin Bracke Left 250x2mm Hot-Dip Galvanized Steel 50pcs Fast​ 833380

Description

The RRF purlin bracket (250 x 2 mm, left-hand version) is a robust structural connector designed to create secure, durable joints in demanding timber structures. It is specifically engineered to transfer forces and establish a stable connection between intersecting timber members—most notably when attaching purlins to primary beams, roof trusses, or load-bearing rafters. Thanks to its carefully engineered profile and offset fastening flanges, the bracket enables efficient force transfer, counteracting both wind-induced uplift and lateral movement within the roof’s structural framework.

It is manufactured from high-quality, hot-dip galvanized sheet steel, which provides effective corrosion protection and a long service life—whether in unheated attic spaces or sheltered outdoor environments. This purlin connector is particularly well-suited for structures where the load-bearing framework will be covered by a ceiling, insulation, or other cladding. It is also ideal for buildings where the visibility of the connector is of no aesthetic concern—such as utility buildings, machinery sheds, warehouses, and garages.

The RRF purlin connector is available in both left-hand and right-hand versions. This specific unit is the left-hand version, offering flexibility during the planning phase and enabling symmetrical installation. To achieve full load-bearing capacity and prevent asymmetrical loading, these connectors are often installed in pairs, with a left-hand and a right-hand connector working together on opposite sides of the intersecting timber beam.

Applications and Structures

The RRF purlin connector is designed for various types of intersecting timber joints:

• Anchoring purlins directly to primary load-bearing beams or glulam beams in roof structures.
• Joining secondary members and structural frameworks in industrial-style buildings, carports, machinery sheds, and agricultural structures.
• Connecting and stabilizing intersecting timber joists in attic floors and truss assemblies.
• Joints requiring high uplift resistance to withstand strong wind loads on the roof.
• Structures that will be concealed behind materials such as gypsum board, timber paneling, ceiling tiles, or exterior cladding.

Material and Corrosion Protection

The connector is manufactured from robust 2.0 mm thick sheet steel, which is hot-dip galvanized to resist moisture and minimize the risk of rust. The substantial steel thickness ensures high torsional rigidity and dimensional stability during installation and under long-term loading. Hot-dip galvanizing provides a comprehensive zinc coating that protects the steel core—even around the punched nail holes—contributing to a secure and durable connection throughout the building's entire lifecycle.

Installation and Fastening

Installation is quick and efficient, thanks to a regular pattern of pre-punched 5.0 mm holes. To achieve the calculated load-bearing capacity, approved fasteners designed for structural connectors must be used:

• Fastening is carried out using 4.0 mm anchor nails or 4.8 mm anchor screws.
• Fasteners should be installed in all—or the specifically designated—nail holes, depending on the structural design calculations and load conditions.
• During installation, the connector must be positioned flush against both the supporting beam and the intersecting rafter (or purlin) before nailing or screwing begins, in order to prevent any gaps.
• For optimal stability and symmetrical load distribution, it is recommended to use a left-hand connector and a right-hand connector on opposite sides of the beam.

Features and Benefits

• High load-bearing capacity: The 2.0 mm thick steel effectively resists tension and uplift forces between intersecting structural components.
• Hot-dip galvanized finish: Provides long-lasting protection against rust and wear, even in Nordic climates.
• Well-positioned nail holes: The 5.0 mm hole pattern is designed to accommodate standard anchor nails and anchor screws.
• Efficient installation: Easy fit against timber, reducing labor time during structural framing and roof construction.
• Left-hand version: Enables correct geometric connection and allows for paired installation with the right-hand version.
