RRF Purlin Bracket Right 250x2mm Hot-Dip Galvanized Steel 50pcs Fast 833379

Description

The RRF purlin bracket (right-hand version) from Fast is a heavy-duty, reliable construction connector developed for structural timber joints in roofs and load-bearing frameworks. The bracket is specifically designed to absorb and transfer forces where timber beams intersect—primarily when anchoring purlins to primary beams. Thanks to its well-engineered design and angled geometry, the bracket provides a firm anchor point that effectively prevents displacement and uplift forces caused by wind loads, snow loads, and other external stresses.

Construction and Stability

This purlin bracket has a height of 250 mm and a material thickness of 2.0 mm, resulting in a highly rigid component that maintains its shape under load. When constructing roof trusses, structural frameworks, and intersecting timber members, high demands are placed on the strength and geometry of the connections. The dimensions of the RRF bracket ensure a generous contact area against both the supporting beam and the purlin, providing optimal load distribution and reducing stress concentrations within the timber. In structures requiring symmetrical attachment and double the load capacity, this specific right-hand version is typically paired with a corresponding left-hand bracket on the opposite side.

Material and Corrosion Protection

The purlin bracket is manufactured from high-quality sheet steel, finished with a durable hot-dip galvanized coating. This galvanization acts as an effective barrier against moisture, oxygen, and environmental factors, protecting the steel from corrosion throughout the entire service life of the building. This makes the bracket an excellent choice for use in ventilated roof structures, unheated attic spaces, and other building components subject to fluctuating temperatures and humidity levels.

Optimal Applications

The RRF purlin bracket is designed for structural building applications, primarily in constructions that will subsequently be covered by cladding, soffits, or facade panels. It is also well-suited for installations where the bracket remains visible, provided that functional strength and the safety of the assembly are the primary priorities.

• Anchoring of secondary purlins to underlying primary beams and roof trusses
• Splicing and stabilization of intersecting members and structural frameworks in roof constructions
• Load-transfer arrangements and stiffening elements in the structural frames of residential buildings, storage structures, halls, and agricultural buildings
• Wind bracing and uplift restraint in load-bearing timber structures

Installation and fastening details

To achieve full design load-bearing capacity and ensure correct load transfer, the connector features a uniform pattern of pre-punched nail holes with a diameter of 5.0 mm. This precise hole pattern offers flexibility in the placement of fasteners and minimizes the risk of the timber splitting when fasteners are installed near the edges of the wood.

• Installation is performed using 4.0 mm connector nails or 4.8 mm connector screws to ensure maximum pull-out and shear resistance.
• The number of fasteners and their placement must be determined based on the design loads specified in the structural drawings.
• Nails or screws must be driven perpendicular to the timber surface and tightened so that the flanges of the connector lie completely flush against the timber substrate.
• In cases of high uplift forces, it is recommended to install connectors on both sides of the purlin by combining right-hand and left-hand versions.

Advantages of the RRF Purlin Connector:

• High load-bearing capacity, effectively resisting uplift and lateral forces on purlins.
• Constructed from 2 mm heavy-duty structural steel for high torsional rigidity.
• Hot-dip galvanized finish for long-lasting, reliable protection against rust.
• Optimized hole pattern for quick and easy installation using standard connector fasteners.
• Standardized geometry that facilitates precise alignment and rapid structural assembly.
