Stackable Thermal Cup Rack Metal

Available in three footprint variants: A (20 × 11 × 10.5 cm), B (20.8 × 20.5 × 10.6 cm), C (20.8 × 30.3 × 10.5 cm). All units built from high-yield, low-carbon steel with anti-corrosion pre-treatment and dual-layer baked enamel finish — tested for 500+ wipe cycles without gloss loss or pigment transfer. Structural integrity confirmed via static load testing: each tier supports ≥8 kg uniformly distributed (equivalent to 6 filled 1L thermal mugs) without deformation. Base includes continuous silicone gasket — not discrete pads — for full-contact grip and acoustic damping. Round-hole sections target narrow-base items (espresso cups, wine flutes, shaker bottles), while adjacent grid zones offer flexible support for irregular shapes (tumblers with handles, contoured travel mugs, collapsible bottles). The stacking mechanism functions via nested rim geometry and self-centring weight bias — no manual locking needed. Height scalability is constrained only by ceiling clearance or upper cabinet depth, with no maximum layer limit specified due to proven load distribution across the entire column. Designed for longevity in high-frequency UK domestic use: compatible with dishwashers (top-rack only), resistant to tea tannin staining, and engineered to retain finish integrity through repeated thermal cycling (e.g., placing hot mugs directly onto cooled metal surfaces). Colour options — matte black, retro white, stainless steel — are matched across all tiers and batch-produced for zero chromatic variance.
