Product Description
The Alu20 SLAT Contractor Line 4′ × 6′ Horizontal Gate Kit is a heavy-duty aluminum pad gate system engineered for professional contractors and experienced homeowners who want a strong pedestrian gate with a clean horizontal-slat design.
Built around a 4″ HD USA aluminum gate frame, the Contractor Line package combines a rigid frame, ALU20 horizontal slats, channel components, a 6′ L-shape gate stopper, and heavy-duty hinge hardware. The 1/2″ gap layout provides a practical balance of privacy, airflow, and visibility, while the current product configuration is also offered with a 3/8″ gap option.
The result is a repeatable aluminum gate package for residential walk gates, side yards, pool-area access layouts, courtyards, gardens, modern aluminum fence systems, light-commercial projects, and multi-family properties.
Benefits: Why Homeowners and Contractors Should Choose It
Contractor-grade strength
Heavy-duty aluminum components are designed for frequent-use pedestrian access and repeatable installations.
Modern horizontal design
Clean architectural lines work with contemporary and traditional exterior settings.
Corrosion-resistant aluminum
6063-T6 aluminum avoids iron-oxide rust and is suited to coastal, humid, and weather-exposed environments.
No-weld assembly
Precision-fit components reduce field fabrication while supporting square, rigid assembly.
Professional finish
Consistent horizontal spacing and a rigid frame create a clean installed appearance.
Multiple post options
The gate can be coordinated with 2″, 2.75″, or 2″ × 3″ aluminum posts based on the project condition.
Applications: Where and How It’s Used
Residential walk gates
A heavy-duty pedestrian-gate format for everyday residential access.
Side-yard & pool access
Horizontal aluminum design for controlled access. Final pool-barrier compliance depends on the complete installation and local requirements.
Courtyard & garden entrances
A clean architectural gate for landscaped and hardscape environments.
Modern fence systems
Coordinate the ALU20 slat pattern with compatible horizontal aluminum fencing.
Light commercial & multi-family
A contractor-grade direction for appropriate higher-use pedestrian access conditions.
A 4″ HD frame, ALU20 slats, channel components, stopper, hinge, and fastening hardware.
The Contractor Line package centers on structural aluminum components sized for a 4×6 single-swing pedestrian gate.
Non-combustible material: the 6063-T6 aluminum substrate is non-combustible. Complete Zone Zero, wildfire, pool-barrier, or other project compliance depends on the full assembly, spacing, hardware, placement, and local requirements. 0120′ gate-frame material
4″ HD USA aluminum gate-frame material for the Contractor Line structure.
02Inner corner bracket
Internal frame connection hardware for square assembly.
03Channel kit
Channel components used to organize and secure the ALU20 slat field.
046′ L-shape gate stopper
Receiver-side stop component for the finished single-swing gate.
05Heavy-duty 5″ two-way support hinge
Heavy-duty hinge hardware for the Contractor Line swing connection.
06#10 × 1″ screws
Specified fastening hardware included in the gate-kit component list.
07#12 × 2″ black screws
Black fastening hardware for the specified gate assembly.
08#10 × 3/4″ screws
Additional assembly fasteners specified for the kit.
09NEW ALU20 slats
2″ × 3/4″ × 6′ horizontal aluminum slats for the gate infill.
Design & Durability: Materials, Finishes, and Customization
The ALU20 Contractor Line uses architectural 6063-T6 extruded aluminum for the frame and slat system. Aluminum is lightweight relative to steel, corrosion resistant, dimensionally stable, and appropriate for long-term exterior gate applications.
The finish direction uses an AAMA 2604 architectural powder-coating system. Powder-coated finishes can be coordinated with matching aluminum fence systems, subject to the finish options available for the order.
The horizontal slat layout can be configured with a 3/8″ or 1/2″ gap. The 1/2″ layout provides more open area for airflow and light while still creating meaningful visual screening.
Installation & Buying Guide: Sizes, Compatibility, Ordering Process
The Contractor Line is intended for pad-mount or surface-mounted installation conditions and is best handled by professional installers or experienced DIYers.
Post selection: choose the support condition based on the actual site, gate weight, hinge configuration, and installation method rather than assuming one post size fits every project.- Finished gate

Six checkpoints from preparation through final alignment.
Use these six installation checkpoints to organize the 4×6 ALU20 Contractor Line assembly from preparation through final alignment.
Preparation
Organize all materials in a clean workspace to avoid damage or misplacement. Confirm the finished opening, post configuration, swing direction, and selected slat gap before assembly.
Frame Assembly
Connect the heavy-duty gate frame with the specified screws, keeping every corner square and secure before installing the slats.
Slat Installation
Insert the ALU20 slats into the channel system and maintain the selected 3/8″ or 1/2″ spacing consistently through the gate. Secure the slats with the specified fasteners.
Hinge Installation
Attach the heavy-duty support hinge to the selected side post and gate frame, maintaining proper alignment for smooth swing.
Post and Gap Cover Installation
Install the selected side support, stopper, and finish components for the actual post and opening condition.
Final Touches
Inspect fasteners, frame squareness, slat spacing, hinge action, stopper contact, closing alignment, and finish surfaces before the gate is placed into service.

Plan the opening, gap, post, finish, installation, and fence coordination before ordering.
These answers cover DIY installation, slat spacing, finish durability, opening size, post compatibility, Contractor Line construction, included parts, material, coastal use, and ALU20 fence coordination.
Is the Alu20 horizontal gate kit suitable for DIY installation?
Yes. The Contractor Line gate is pre-engineered and does not require welding for the supplied frame assembly. It is best suited to professional installers and experienced DIYers who can verify the opening, post condition, hinge alignment, frame squareness, and final hardware setup.
What does the 1/2″ gap mean on a horizontal slat gate?
A 1/2-inch gap is the open space between adjacent horizontal ALU20 slats. It provides partial visual screening while allowing airflow and light through the gate. The current product is also offered with a 3/8-inch gap option.
Will the aluminum color fade over time?
The gate uses an architectural powder-coated finish intended for exterior UV and weather exposure. Like any exterior finish, appearance can change gradually over a long service period, but routine cleaning and correct care help maintain the surface.
What size opening does this gate kit fit?
The gate is configured to build a finished 4-foot-wide by 6-foot-high single-swing gate. Confirm the actual rough opening, hinge-side support, latch-side clearance, post size, and installation method before ordering.
What post sizes are compatible with the Alu20 gate kit?
The product content identifies 2-inch, 2.75-inch, and 2-inch by 3-inch aluminum post options. Final post selection depends on site conditions, gate weight, hinge configuration, and installation method.
Why choose a contractor-line aluminum gate over a standard gate?
The Contractor Line uses a 4-inch heavy-duty aluminum frame, heavy-duty hinge hardware, and a repeatable component package intended for frequent-use pedestrian access and professional installation conditions.
What components are included in the Contractor Line kit?
The product content lists 20 feet of 4-inch HD USA aluminum gate-frame material, an inner corner bracket, channel kit, 6-foot L-shape gate stopper, heavy-duty 5-inch two-way support hinge, #10 x 1-inch screws, #12 x 2-inch black screws, #10 x 3/4-inch screws, and new ALU20 2-inch x 3/4-inch x 6-foot slats.
What material and coating system is used?
The gate uses architectural 6063-T6 extruded aluminum with an AAMA 2604 powder-coating direction. The aluminum substrate is corrosion resistant and non-combustible.
Is this gate suitable for coastal or humid environments?
Yes. Aluminum and architectural powder coating are well suited to corrosion-conscious exterior material selection, including coastal and humid environments. Routine rinsing is useful where salt or airborne contaminants can collect.
Can this gate coordinate with ALU20 fencing?
Yes. The ALU20 horizontal slat pattern is designed to coordinate with compatible ALU20 fence systems, post configurations, and powder-coated finishes.
Coordinate the complete 4×6 gate before the material reaches the job site.
