Key principles.
Standard
Triangular braces between perpendicular surfaces. Most efficient.
60% wall
Gusset thickness 60% of wall (sheet metal) or rib (plastic).
Per stiffness
Taller = stiffer. 3-5× wall height typical.
Avoid sharp corners
Generous fillets at gusset attachment. Reduce stress concentration.
Adequate fillet
Weld both sides of gusset for adequate strength.
Sink mark prevention
Same rules as plastic ribs. 60% rule prevents sink marks.
FAQ
Sheet metal corners, structural transitions, plastic features needing stiffness.
Gussets enable thin walls + stiffness. Solid wall: simpler but heavier.
Triangular more efficient. Rectangular OK but heavier for same stiffness.
Same material as base — easy to weld. Different material possible with bolted attachment.
Both sides for full strength. Single-side OK for low-load. Per AWS for structural.
Same as ribs. 60% wall thickness, generous fillet, draft for ejection.
