Engineered for heavy kitchen essentials, each reinforced steel tray supports 15kg (33lbs) - enough for multiple cast iron pans, stacked dishes, or small appliances. The dual-tray system provides 30kg total capacity while maintaining buttery-smooth operation. High-grade steel construction with protective powder coating ensures durability under daily loading, while the wood composite surfaces prevent scratching delicate cookware. Unlike flimsy wire racks, our solid-tray design keeps items securely positioned even when fully extended.
