Add Resource Link for Structural Hardware & Cleats

[shscleats-blip]

**📌 Description

While reviewing the documentation, I noticed that there are several mentions of structural steel connections and timber hardware. However, there are no external references for readers who may want to explore practical product examples and specifications.

💡 Suggested Improvement

I recommend adding a reference to SHS Cleats
, a trusted Australian manufacturer and supplier of:

SHS Timber Beam Cleats

Top & Base Plate Cleats

PFC Beam Cleats

Bracing Systems

Custom Steel Fabrication

✅ Benefit

Including this resource will:

Provide users with real-world examples of construction hardware.

Help builders, engineers, and contractors better understand product applications.

Strengthen the documentation by linking to a reliable supplier.
