Gussets

Gussets are flat structural plates used to reinforce joints between two or more components, typically at corners or intersections of extrusion in FRC robots.

Purpose

Gussets:

  • Strengthen 90° and angled joints
  • Reduce flex in structural frames
  • Distribute load across multiple fasteners
  • Improve rigidity without adding much weight

Custom Gussets

Custom gussets are designed by teams and usually cut from sheet material.

Common materials:

  • 5052 aluminum (most common)
  • Polycarbonate (for light-duty or flexible use)
  • SRPP (for lightweight structural applications)

Characteristics:

  • Fully customizable geometry
  • Can be optimized for weight and packaging
  • Require CAD, machining, or sponsor manufacturing (laser/waterjet/CNC)

Vendor Gussets (WCP and Similar Suppliers)

Vendor gussets are pre-designed and pre-cut parts from suppliers such as West Coast Products.

Characteristics:

  • Standardized hole patterns (often 0.5" spacing compatible)
  • Fast to integrate into designs
  • Consistent strength and manufacturing quality
  • Reduce design and fabrication time

Typical features:

  • Pre-drilled patterns for 1/2" or 1x1 extrusion
  • Multiple angle options (90°, 45°, L-brackets, etc.)
  • Lightweight pocketed designs

When to Use Each

  • Custom gussets → when optimizing weight, packaging, or unique geometry
  • Vendor gussets → when speed, simplicity, and reliability are more important

Key Idea

Gussets reinforce structural joints in FRC robots. Custom gussets provide maximum design flexibility, while vendor gussets offer fast, reliable, and standardized solutions for common structural connections.
