The Alu40 18′ × 6′ Sliding Gate Kit (HD USA – NEW) is designed to deliver structural strength, dependable movement, and long-term durability across wide spans.
Key benefits include:
Heavy-duty HD USA aluminum construction: Reinforced 4″ aluminum frame resists flexing and sag across long openings.
Space-efficient sliding design: Ideal for sites where swing gates are impractical or restricted.
Smooth and stable operation: Precision C-track, guide roller, and gate stopper ensure controlled, reliable movement.
Low maintenance performance: Aluminum construction will not rust, warp, or require repainting.
Modern visual appeal: Clean horizontal layout with black Alu40 infill complements contemporary architecture.
Contractor-ready system: Engineered components reduce install time and ensure consistent, repeatable results.
For contractors, this means fewer adjustments and long-term performance confidence. For property owners, it means a secure, visually striking gate that holds up over time.
The gate frame is constructed from 20 feet of 4″ HD USA aluminum, engineered to maintain rigidity across extended spans. Reinforced inner corner brackets and internal connectors ensure structural alignment, while the channel system supports smooth, controlled gate travel.
The system includes the NEW Alu40 6′ black infill, finished with a durable powder-coat designed to resist UV exposure, corrosion, and surface wear. A 3″ aluminum cap completes the top edge for a clean, finished appearance.
