Buying Guide
What to consider when choosing heavy duty flat brackets:
- Load capacity: Larger, thicker brackets generally handle more weight. Match bracket size to the anticipated load and span.
- Material and finish: Stainless steel offers corrosion resistance; powder-coated finishes help with outdoor use and aesthetics.
- Hole pattern and screw length: Ensure holes align with your joint design and that screws won’t protrude beyond the opposite surface.
- Installation surface: Wood, metal, or combination joints may require different screw types and pre-drilling.
- Span and coverage: Longer brackets spread stress across a larger area; shorter brackets fit tighter spaces.
