What Does a Complete Fence System Actually Include? Posts, Rails, Infills, Gates, and Hardware Explained

"Complete fence system" gets used a lot. What it actually covers varies more than the label suggests. Some systems include posts and panels but treat the gate as a separate purchase. Others bundle the gate but leave hardware off the list. This guide breaks down what a genuinely complete system should include, and what to check before you commit.

At a glance

A complete fence system covers five things: 

• posts, 

• rails, 

• infill panels, 

• a gate,

• hardware

The gate and lock should be part of that same design, not sourced separately. 

Modern Yard's modular fence and gate system covers all five across composite, steel, and aluminum material options.

What each component does, and what goes wrong without it

1. Posts

Posts anchor everything. If the post dimensions don't match the rail system, you're looking at field cutting before anything goes up. If the posts aren't engineered for outdoor exposure, corrosion starts from the inside out, quietly. Check that the post profile is specified to work with the rails, not sold as a generic structural post.

2. Rails

Rails hold the infill between posts. The thing to verify is whether the rails are matched to the specific infill you're choosing. Generic rails often don't account for board thickness or spacing requirements, which shows up as gaps or uneven spacing after installation.

3. Infill panels

The infill is what your fence actually looks like. It also determines maintenance load, climate performance, and whether the fence meets local requirements. If you're in a fire zone, not all infill materials qualify. In a well-designed system, the infill dimensions are matched to the rail profile so standard configurations go together without modification.

4. Gate

The gate is where most homeowners run into trouble. It carries its own weight on hinges, gets opened and closed daily, and needs to stay aligned over time without sagging. If the gate frame isn't designed to accept the same infill as your fence, the finished project won't match. If the gate comes from a different manufacturer, expect to work through hinge sizing, lock fitment, and finish inconsistencies on-site.

5. Hardware 

Hardware is the most underdefined part of most fence system descriptions. It should cover hinges rated for the gate weight, corrosion-resistant fasteners matched to the infill material, and a lock compatible with the gate frame.

Please note. When a system says "hardware included," ask what's specifically in scope. Hinges, locks, and fasteners are not always bundled together under that label.

What hardware actually covers

In a complete gate system, hardware falls into three things:

• Structural fasteners. 

  Screws, bolts, and brackets that hold the fence components together. Should be corrosion-resistant and matched to the material they're securing.

  
  

• Gate hardware.

  Hinges and mounting hardware for the gate frame. In a well-integrated system, hinges come pre-installed and the lock mount is pre-drilled. That removes the most error-prone steps from installation.

  
  

• Access control.

  The lock or latch. For outdoor gates, it should be rated for outdoor conditions and compatible with the gate frame thickness without requiring on-site drilling.

  
  

What to ask before you buy

These aren't technical questions. They're the practical ones worth raising with any dealer before you commit.

Does the gate come with the system, or is it separate? 

Many fence systems are sold without a gate. If you need one, you're sourcing it separately, which means a separate compatibility check for every connection point.

What hardware is actually included? 

Get a specific list: hinges, lock, fasteners, brackets. "Hardware included" without a breakdown is worth clarifying.

Are the rails and infill matched, or do I need to verify sizing myself?

In a purpose-built system, the rail profile is specified by infill type. If the answer is "you'll need to check," the components likely weren't designed together.

Is installation documentation available? 

A PDF manual and installation video per product is a reasonable expectation. If those don't exist, post-purchase questions get harder to resolve.

Does one warranty cover the whole system? 

Split warranties across manufacturers make claims complicated. A single warranty covering the full system is a meaningful signal.

The Modern Yard System

Modern Yard is a modular fence and gate system built around a single slotted steel post that supports fence panels, gate frames, and hardware across three material lines.

Posts. 

The Modern Yard slotted steel post works as both a fence post and gate post, so you're not buying two different types for one project. Triple-coating system: galvanized zinc, epoxy primer, electrostatic powder coating, with foam-sealed ends to block internal moisture.

Rails. 

Two rail systems. myRail-System-Horizontal for composite boards in horizontal layouts. myRail-System-Vertical for FireGuard steel panels. myAir aluminum slats install directly into the post slot with no rail set needed.

Infill panels. 

Three options. myRedwood composite board for residential horizontal and vertical layouts. myFireGuard steel panel, tested to ASTM E84 Class A and listed on the California Fire Safe Council Vendor List, for WUI and fire zone projects. myAir aluminum slat for a ventilated, open modern look.

Gate frames.

Fully welded aluminum. Accepts the same infill as the fence, so the gate matches without coordination work. Aluminum hinges are included in the package and installed during assembly. Lock mount is pre-drilled.

Hardware.

 The myLock-Combination is a 304 stainless steel sequential mechanical lock, 665,000 unique code combinations, no battery, 25-year limited warranty. Fits gate frames 1-1/4" to 1-7/8" thick. Mounts directly into the pre-drilled position on the gate frame.

Installation tip. Step-by-step videos, PDF manuals, and technical drawings for every product are at the Modern Yard installation guides page. Each guide is product-specific, not a generic overview.

Start with the system, not the components

The most common fence project frustration isn't the installation. It's discovering mid-project that something doesn't fit: posts that don't match the rails, a gate from a different supplier, a lock that needs custom drilling. A system designed as a whole moves those decisions to before you order, where they're easier to resolve. The Modern Yard product catalog lists every component with its compatibility relationships so you can verify the full picture upfront.
