What the AI looks for in Fencing Railings & Pickets
- Guard height
- US residential codes (IRC) generally require guards at least 36 inches high where the walking surface is more than 30 inches above grade; commercial work and some jurisdictions require 42 inches Rails and pickets must be bought to the height your inspector will accept, not cut down later.
- Opening size
- A 4-inch sphere must not pass through any opening in the guard This is the rule that sets baluster spacing and rules out many decorative layouts.
- System compatibility
- Buy rails, balusters, connectors and post sleeves from the same system, or confirm the manufacturer lists them as compatible Hole spacing, baluster profiles and bracket sizes differ between brands, and mixed parts often do not fit.
- Fasteners for treated lumber
- Use stainless steel or hot-dip galvanized fasteners and connectors rated for contact with pressure-treated lumber Modern copper-based preservatives corrode plain or electroplated steel quickly.
- Material match
- Match the material to the deck: pressure-treated wood, cedar, composite or aluminum, each with its own finishing and maintenance needs Wood needs periodic sealing, while composite and powder-coated metal do not.
Brands that matter
- Trex: Composite and aluminum railing systems sold as matched components.
- TimberTech: Composite and aluminum railing lines designed to pair with its decking.
- Fortress Building Products: Steel and aluminum railing and baluster systems.
- Deckorators: Known for aluminum and decorative balusters that fit wood or composite rails.
- Nuvo Iron: Budget-friendly metal balusters and railing components.
What to avoid
- Mixing rail and baluster brands without checking hole spacing and connector fit.
- Electroplated or plain steel screws in pressure-treated lumber.
- Layouts that leave gaps of 4 inches or more.
