Simpson Strong Tie Heavy Engineered Strap Bent

High-Performance Restraint Straps with Reinforced Bend for Structural Stability

Overview

The Simpson Strong Tie Heavy Engineered Strap Bent range offers a next-generation solution for structural restraint applications, replacing traditional heavy-duty bent straps with a design optimized for strength, efficiency, and ease of installation. These bent straps are essential in securing timber elements such as wall plates, roof trusses, and floor joists to masonry walls, providing lateral and vertical restraint in accordance with building regulations.

Available in multiple lengths (600mm, 1000mm, 1200mm, and 1500mm), these straps are manufactured from 1.5mm thick galvanized steel, making them lightweight yet structurally robust. Their formed edge and reinforced corner design significantly enhances performance, particularly at stress points, while also eliminating the need for joist or block notching—saving time and effort during installation.

Product Specifications

• Thickness: 1.5mm

• Material: Galvanised steel

• Design: Pre-bent with formed edge and reinforced corner

• Compliance: Conforms to BS EN 845-1 standards (1000mm variant explicitly stated)

Key Features

• Reinforced Corner Design
  Provides added strength at the bend, a critical area where traditional straps often experience weakness under load.

• 1.5mm Thin Profile
  Strong enough to meet structural requirements while thin enough to be installed without the need for notching joists or masonry blocks, ensuring faster and simpler fitting.

• Formed Edge for Extra Rigidity
  The formed edge detail improves the overall rigidity of the strap, enhancing performance without increasing material thickness.

• Easy Installation
  Designed to fit over the top of floor joists and truss bottom chords, simplifying alignment with blockwork courses and reducing time on site.

• Corrosion Resistant
  Manufactured from galvanised steel, providing protection against rust and corrosion in indoor and protected outdoor environments.

• Regulatory Compliance
  Meets the stringent requirements of BS EN 845-1 for wall ties, straps, and other structural components used in masonry construction.

Applications

• Lateral Restraint of Roof Trusses and Rafters
  Helps anchor timber roof structures to masonry walls, reducing lateral movement under wind load or shifting.

• Vertical Restraint of Wall Plates
  Ideal for use on top of masonry walls where wall plates require secure anchoring.

• Securing Floor Joists to Walls
  Ensures horizontal restraint of floor systems in accordance with UK Building Regulations.

• General Structural Strengthening
  Can be used in new builds, extensions, or retrofit projects where a reliable restraint solution is required.

Installation Notes

• Fixing Method: Use all specified fasteners—typically steel screws or round nails—to fix securely to both timber and masonry.

• Positioning: The strap should be placed so the reinforced bend sits at the intersection of the timber and masonry. No notching required.

• Spacing: Follow applicable building regulations regarding strap spacing and fixing positions (commonly every 2m for horizontal restraint).

• Blockwork Compatibility: Easily courses with blockwork due to its thin profile.

Benefits

• Reduced labour time with no notching required

• Higher strength at structural stress points

• Fully compliant with UK and EU building standards

• Durable and corrosion resistant

• Versatile length options to suit a variety of building layouts

Available Variants

• 600mm – Compact for limited space applications

• 1000mm – Most commonly used for standard installations

• 1200mm – Extra length for added restraint reach

• 1500mm – Longest option for large-scale connections

Conclusion

The Simpson Strong Tie Heavy Engineered Strap Bent series is an advanced solution for builders and contractors seeking a high-performance, regulation-compliant restraint strap that saves installation time while delivering excellent structural support. Its reinforced construction and user-friendly design make it ideal for both modern builds and renovation projects.
