RRF Purlin Bracket Right 210x2mm Hot-Dip Galvanized Steel 50pcs Fast 833377

Description

The RRF purlin bracket (right-hand version, 210x2 mm) is a high-quality, purpose-designed construction connector, engineered to create reliable, stable, and torsionally rigid connections within load-bearing timber structures. Specifically developed for anchoring purlins to primary beams and roof trusses, this component is essential in roof construction, where robust mechanical connections are required to withstand both uplift forces (from wind) and vertical loads.

The bracket consists of a bent profile made from 2.0 mm thick steel, featuring strategically positioned holes for fasteners. Its asymmetrical, right-hand design allows it to fit snugly against the side and top of a timber beam, providing a clean contact surface and a highly stable connection between intersecting timber elements.

Applications and Structural Solutions

The RRF purlin connector is primarily used in timber construction where floor joists or roof rafters meet at an angle or intersect. Common applications include:

• Anchoring secondary purlins to underlying primary beams or glulam beams in roof structures.
• Stabilizing and connecting intersecting beams in industrial halls, warehouses, and machinery sheds.
• Structural joints in carports, garages, outbuildings, and storage structures.
• Constructions where the load-bearing framework is covered by a sub-roof, paneling, or insulation, concealing the connector.
• Projects where visible connectors do not detract from the overall aesthetic, or where functionality and load-bearing capacity are the primary priorities.

Materials and Corrosion Protection

The connector is manufactured from durable, dimensionally stable sheet steel that has been hot-dip galvanized. This process creates a comprehensive, robust zinc coating that protects the underlying steel against moisture and corrosion. As a result, the purlin connector retains its structural strength and load-bearing capacity throughout the entire lifespan of the building even in cold attic spaces or ventilated roof environments where moisture levels and temperatures may fluctuate.

Advantages of the RRF Purlin Connector (Right-hand version)

• Provides a precise, high-strength anchor that prevents displacement and resists uplift forces between the purlin and the supporting beam.
• Constructed from 2 mm thick heavy-duty steel for superior stability and resistance to deformation.
• Hot-dip galvanized steel provides long-lasting protection against rust and external environmental factors.
• Optimized hole pattern with 5.0 mm round holes, offering flexibility during fastening and minimizing the risk of the timber cracking.
• Easy and time-efficient installation on the construction site.

Installation instructions and recommended fasteners

To achieve full load-bearing capacity and ensure proper structural interaction within the timber connection, the installation must be performed using fasteners designed for construction connectors. The 5.0 mm hole diameter is intended for:

• 4.0 mm diameter connector nails.
• 4.8 mm diameter connector screws.

To install, position the connector flush against both the primary beam and the purlin so that no gaps remain. Then, secure the connector using the number of nails or screws specified in the structural design drawings. Using connector screws simplifies installation in tight spaces and ensures uniform clamping pressure. For symmetrical or heavy-duty structures, the right-hand version can be paired with a corresponding left-hand version on the opposite side of the beam.
