Metal Fence Panel Systems: Welded vs Assembled, Costs & Installation Tips

Metal fence panels are one of the highest-margin products a fence contractor can install. But the range of options — welded steel, assembled aluminum, ornamental iron, tubular steel — can make quoting tricky if you don't know the differences.

This guide breaks down the major metal panel systems, what they cost, and how to bid them profitably.

Welded Steel Panels vs Assembled Aluminum Panels

These are the two big categories, and they serve different markets.

Welded Steel Panels

Welded steel panels are fabricated in a shop or factory. Pickets are welded to horizontal rails, creating a rigid one-piece panel.

Characteristics:

Heavy and extremely durable
Typically powder-coated or galvanized (or both)
Standard panel widths: 6' or 8'
Heights: 3' to 8' (4' and 6' most common for residential)
Requires heavier posts (2.5" x 2.5" or 3" x 3" steel)

Best for: Commercial properties, high-security perimeters, pool enclosures in code-strict areas, customers who want a premium look.

Assembled Aluminum Panels

Assembled (also called "screwed" or "racked") aluminum panels use pickets inserted through pre-punched rails and secured with fasteners. No welding required.

Characteristics:

Lightweight — easier to handle and install
Rack on slopes without custom fabrication
Won't rust (aluminum doesn't corrode like steel)
Standard panel widths: 6' or 8'
Heights: 3' to 6' typically
Posts: 2" x 2" or 2.5" x 2.5" aluminum

Best for: Residential properties, sloped terrain, coastal/humid climates, budget-conscious homeowners who still want a metal fence look.

Cost Comparison: Metal Fence Panels by Type

Here's what you'll typically pay for materials (contractor cost, not retail) and what the installed price looks like:

Panel Type	Material Cost/LF	Installed Price/LF	Notes
Assembled aluminum (residential grade)	$8-$15	$25-$40	Most common residential metal fence
Assembled aluminum (commercial grade)	$14-$22	$35-$55	Thicker walls, larger pickets
Welded steel (residential ornamental)	$15-$25	$35-$55	Powder-coated, decorative tops
Welded steel (commercial/industrial)	$20-$40	$50-$85	Heavy gauge, anti-climb options
Ornamental wrought iron	$25-$50	$55-$100+	True wrought iron is rare — most is mild steel
Tubular steel	$12-$20	$30-$50	Good middle ground, common in commercial

These are 2026 estimates. Your local market, supplier relationships, and volume will shift these numbers.

Ornamental Iron vs Tubular Steel

Contractors sometimes use these terms interchangeably, but there are differences:

Ornamental iron (mild steel):

Solid or hollow pickets, often with decorative finials
Heavier gauge material
Typically welded construction
Requires high-quality coating to prevent rust
Premium product, premium price

Tubular steel:

Hollow tube pickets and rails
Lighter than ornamental iron but stronger than aluminum
Available in both welded and assembled configurations
More affordable than ornamental iron
Good commercial option

When to recommend each:

Ornamental iron for high-end residential estates and historic properties
Tubular steel for commercial, HOAs, and customers who want metal but have a mid-range budget

Powder Coating vs Galvanizing

How you protect steel panels determines how long they last — and what you can warranty.

Powder Coating

Electrostatically applied dry powder, cured with heat
Available in any color (black is 80%+ of orders)
Looks great initially
Can chip, scratch, and eventually fade
Lifespan: 10-20 years depending on quality and climate

Hot-Dip Galvanizing

Steel is dipped in molten zinc
Provides sacrificial corrosion protection
Silver/gray appearance (not decorative on its own)
Extremely long-lasting: 30-50+ years
Can be powder-coated over galvanizing for best protection

The Best Option: Galvanized + Powder Coated

For any steel fence that needs to last, galvanize first, then powder coat. Yes, it costs more — about $3-$6/LF extra — but it's the gold standard. This is what you should push on commercial specs and high-end residential.

Coating Method	Added Cost/LF	Expected Lifespan	Best For
Powder coat only	$0 (included)	10-20 years	Budget residential
Galvanized only	$2-$4	30-50 years	Industrial, not decorative
Galvanized + powder coat	$3-$6	40-60+ years	Commercial, coastal, premium

Labor Considerations for Metal Panel Installation

Metal panels install differently than wood or vinyl, and your labor pricing should reflect that.

Typical production rates:

Assembled aluminum: 80-120 LF/day (2-person crew)
Welded steel residential: 60-90 LF/day (2-person crew)
Welded steel commercial: 40-70 LF/day (2-3 person crew, heavier panels)

What slows you down:

Slopes and grade changes (aluminum racks easily, steel needs stair-stepping or custom panels)
Rocky soil (post holes for steel posts need to be deeper and wider)
Gates (metal gates are heavy, hardware is finicky, automation adds complexity)
Existing landscaping (metal panels are less forgiving of obstacles than wood)

What speeds you up:

Flat terrain
Pre-set posts (set posts day 1, hang panels day 2)
Using panel brackets instead of welding to posts on-site
Consistent panel lengths (avoid lots of custom cuts)

Gate Compatibility

Gates are where metal fence jobs get complicated — and profitable. Metal fence gates need to match the panel style exactly, so you're usually ordering from the same manufacturer.

Key gate considerations:

Single swing gates — up to 5' wide, standard hinges
Double swing gates — 6'-16' opening, need center drop rod or cane bolt
Sliding gates — 12'-30' openings, need track or cantilever system
Automated gates — add $1,500-$5,000+ for operator, controls, and safety devices

Margin tip: Gates are where your margin lives on metal fence jobs. A $300 gate with $200 in hardware and automation can bill out at $1,500-$3,000 installed. Don't underprice gates.

Popular Manufacturers (2026)

Here are the brands most fence contractors work with:

Jerith — The standard in aluminum. Wide product line, good dealer support, residential and commercial.
Ameristar (Assa Abloy) — Commercial and high-security. Montage and Echelon lines are popular.
Merchants Metals — Major distributor/manufacturer. Good commercial steel options.
Ultra Aluminum — Competitor to Jerith, good pricing, strong in the Northeast.
Specrail (Master Halco) — Residential aluminum, distributed through Master Halco network.
Ideal Aluminum — Industrial-grade aluminum, commercial focus.
Fortress Building Products — Pre-packaged panels for residential, sold through big-box channels too.

Dealer tip: Establish direct dealer accounts with 1-2 manufacturers. You'll get better pricing, warranty support, and access to custom fabrication.

Residential vs Commercial: Which Jobs to Chase

Factor	Residential	Commercial
Average job size	100-300 LF	500-5,000+ LF
Margin	35-50%	20-35%
Payment speed	Faster (homeowner pays at completion)	Slower (net 30-60 typical)
Complexity	Lower	Higher (specs, submittals, inspections)
Competition	High	Moderate
Repeat business	Occasional	Significant

Most contractors do best with a mix — residential for cash flow, commercial for volume and relationship building.

Bidding Tips for Metal Panel Jobs

Measure exactly — Metal panels are fixed widths. You need to know where cuts fall.
Account for end posts, corners, and gate posts — These are all different and priced separately.
Price gates individually — Don't bundle gate cost into per-foot pricing.
Include concrete — Metal posts need solid footings. Budget 2-3 bags per post.
Check local code — Pool fences, front yard fences, and fences near roads often have height and style restrictions.
Add for slope — Stair-stepped steel panels cost more than raked aluminum. Quote accordingly.
