RRF Purlin Connector Left 170x2mm Hot-Dip Galvanized Steel 50pcs Fast​ 833376

Description

The Fast RRF Purlin Connector (170x2 mm, left-hand version) is a robust structural connector designed for the reliable joining of load-bearing timber elements in roof and floor framing. The connector is specifically engineered to resist uplift and shear forces that occur where purlins meet primary beams or other intersecting timber members. By creating a stable, geometrically precise connection point, it ensures that the roof structure maintains its structural integrity, even under varying loads from wind, snow, and the structure's own weight.

Applications and Usage Environments

This purlin connector is primarily intended for joining and anchoring intersecting timber members most notably between purlins and load-bearing primary beams. It is ideally suited for construction projects where the load-bearing framework is covered by internal or external cladding, such as roof underlayment, paneling, or sheet materials. It is also excellently suited for structures and spaces where the visibility of the connector is of no aesthetic concern, such as unheated attic spaces, machinery sheds, carports, utility buildings, and storage sheds.

Material properties and corrosion protection

The RRF purlin connector is manufactured from high-quality, hot-dip galvanized sheet steel with a thickness of 2.0 mm. The hot-dip galvanizing process creates a durable zinc layer that protects the underlying steel against oxidation, moisture, and corrosion. This makes the connector well-suited for Nordic construction conditions and environments subject to recurring humidity. The robust material retains its shape and load-bearing capacity without sagging or deforming during installation or under long-term loading.

Design and left-hand version

The connector is manufactured in two mirror-image versions: right-hand and left-hand. This item refers to the left-hand version, meaning the angle and positioning of the flanges are adapted for installation on a specific side of the timber joint. The carefully designed hole pattern ensures optimal force distribution across the timber surface and minimizes the risk of the wood splitting during nailing or screwing. In structural calculations, right-hand and left-hand connectors are often combined diagonally or in pairs to achieve full symmetrical load-bearing capacity and prevent distortion within the joint.

Installation instructions and fastening details

Proper fastening is crucial for achieving maximum strength in the timber joint. The purlin connector features pre-drilled 5.0 mm holes, optimized for 4.0 mm connector nails or 4.8 mm connector screws. To install, position the connector firmly against the adjoining timber members and secure it using the recommended fasteners in all designated holes, as specified in the structural drawings.

Important installation considerations:

• Ensure that the timber members fit tightly against the contact surfaces of the connector before fastening.
• Use 4.0 mm connector nails or 4.8 mm connector screws to ensure full load transfer.
• Avoid overtightening screws, as this can damage the wood fibers or compromise the strength of the connection.
• Follow all applicable structural guidelines and design codes for timber construction when positioning the connectors.

Advantages of the RRF Fast Purlin Connector:

• Creates a mechanically strong and reliable connection between the purlin and the supporting beam.
• Hot-dip galvanized steel provides effective, long-lasting protection against moisture and corrosion.
• The 2 mm thick steel plate offers high rigidity and resistance to torsional forces.
• A hole pattern designed for standard fasteners facilitates quick and accurate installation.
• The left-hand version allows for geometrically correct assembly in systems that require mirrored (symmetrical) connectors.
