Design & Durability
The DIY Double Gate ALU20 Slat Universal DIY 12×6 Horizontal Double Swing Gate showcases the best of modern engineering in a simple, modular design.
Its frame is constructed from precision-extruded aluminum profiles that deliver exceptional strength-to-weight performance. The ALU20 series features a refined slat design that’s lighter than heavy-duty contractor lines like ALU40 or ALU60, yet still robust enough for residential use. This makes it the ideal balance of strength, affordability, and ease of assembly.
Every component is powder-coated to a high-grade outdoor standard (AAMA 2604 equivalent), providing UV resistance, corrosion protection, and color longevity — even under harsh sun exposure. The result is a modern horizontal gate that won’t fade, peel, or warp over time.
Aesthetically, the horizontal slat configuration offers a sleek, architectural profile that complements everything from mid-century modern homes to minimalist new builds. Choose from a variety of finishes — such as matte black, white, or wood-grain effects — to match your fence or exterior palette.
Customization is another strength of the ALU20 system: slats can be trimmed for width adjustments, and optional post kits or hinge upgrades are available for uneven terrain or wider openings. The modular design ensures your installation looks custom-fabricated, even though it’s built right at home.

Install hinges and latches according to swing direction, making sure the double gate meets evenly at the center.
