Product Overview

The Simpson Strong Tie Heavy Duty Angle Bracket range is engineered to provide high-strength, multi-directional support in structural timber connections. Made from 3.0mm thick pre-galvanised mild steel, these brackets offer robust resistance against tension, compression, and shear forces, making them suitable for load-bearing joints in timber frames, roof structures, and cladding systems.

These brackets ensure consistent structural integrity, even under demanding conditions, and are ideal for applications where safety, durability, and compliance with building standards are critical.

Key Features

• Heavy-Duty Construction
  Manufactured from 3.0mm thick pre-galvanised mild steel, ensuring high strength, stability, and long service life in both indoor and sheltered external environments.

• High Load Capacity in All Directions
  Designed for multi-directional loading, allowing transfer of loads vertically, laterally, and diagonally. Offers increased strength in tension and shear.

• Full and Partial Nailing Performance
  Optimised for full or partial nailing patterns, ensuring flexibility in installation while still maintaining excellent load-bearing capabilities.

• Wide Range of Applications
  Suitable for structural connections including:

  • Small trusses

  • Cladding plates and uprights

  • Cantilevered beams and rafter anchors

  • Joist-to-beam and beam-to-column connections

  • Wall plate reinforcement

  • Headers and corner junctions

• Pre-Galvanised Finish
  Provides corrosion resistance and durability, suitable for sheltered outdoor use or moist indoor environments.

Installation Advice

1. Positioning

   • Align the bracket against the timber-to-timber or timber-to-concrete junction.

   • Ensure a flush, tight fit for optimal performance.

2. Fixing

   • Use appropriate fixings such as galvanised nails (4.0mm diameter) or countersunk screws or bolts.

   • For structural use, it is strongly recommended to follow the manufacturer’s nailing schedule (available in Simpson Strong Tie technical documentation).

3. Nailing Patterns

   • Use full nailing to achieve maximum strength.

   • Partial nailing may be used for lighter loads or where spacing limits full fixing—consult engineering guidance.

Common Applications

• Timber frame buildings

• Joist hangers and trimmers

• Reinforcement at beam ends

• Securing wall plates to uprights

• Roof rafter and truss connections

• Cantilever and corner junction strengthening

• Internal and external cladding support

Benefits

• Superior structural performance and durability

• Versatile usage across timber-framed structures

• Quick and simple installation with standard fixings

• Resistant to warping, twisting, or deformation under load

• Trusted by engineers, builders, and timber frame manufacturers

Frequently Asked Questions (FAQ)

Q1: What is the main purpose of a heavy duty angle bracket?

A: Heavy duty angle brackets are used to create strong, stable 90-degree joints between timber elements. They provide enhanced load transfer and structural rigidity in high-stress applications such as roof trusses, beams, and cantilevered timber.

Q2: Can these brackets be used externally?

A: While they are galvanised for corrosion resistance, they are recommended for internal use or sheltered external applications. For fully exposed outdoor use, stainless steel brackets may be more appropriate.

Q3: How many fasteners are required?

A: The exact number depends on load conditions and application. Refer to Simpson Strong Tie’s installation guide or engineering tables. Typically, using at least 4–6 nails or screws per side is advisable.

Q4: Are these brackets suitable for masonry?

A: These are primarily intended for timber-to-timber or timber-to-steel applications. For timber-to-masonry connections, consider using masonry-compatible angle brackets or wall starters.

Q5: What tools are needed for installation?

A: A hammer or nail gun for nails, or a drill/driver for screws or bolts. Always ensure fixings are flush and not overdriven to maintain bracket integrity.

Q6: Do these brackets comply with building regulations?

A: Yes. These brackets are manufactured in accordance with BS EN 14545 and Eurocode EC5, ensuring compliance with UK and EU structural building standards when installed properly.

Q7: Can I use this for furniture or DIY shelving?

A: These brackets are over-engineered for light furniture use, but they can be used where superior strength and durability are desired. For smaller DIY projects, a light-duty bracket may suffice.

Q8: Are technical datasheets or load tables available?

A: Yes. Simpson Strong Tie provides full technical datasheets, load capacity tables, and CAD drawings upon request or via their website. These should be consulted for load-bearing projects.

Conclusion

The Simpson Strong Tie Heavy Duty Angle Brackets provide high-performance, reliable timber connection solutions for critical structural joints. Whether you’re building a roof, extending a timber frame, or reinforcing load points, these brackets deliver outstanding strength, versatility, and long-term performance trusted across the construction industry.
