Key Features & B2B Manufacturing Advantages

1. Multi-Point 6-Hole Anchor Geometry
   The six countersunk screw holes spread heavy dynamic seating and sleeping loads across a wide area, preventing wood frame splitting or screw pull-out.

2. Anti-Rust Galvanized Zinc Coating
   The electro-zinc plated finish shields internal steel plates against humidity inside foam and fabric padding, ensuring rust-free performance.

3. Flush-Mount Flat Alignment
   Folds 180 degrees completely flat, keeping frame joints flush and eliminating uncomfortable protrusions under mattress cushions.

4. Streamlined Factory Production Assembly
   Pre-drilled countersunk holes allow assembly line workers to drive wood screws rapidly into wooden base rails using standard power tools.
