Consist of three primary categories: metal, plastic, and resin. Metal materials primarily include stainless steel and aviation-grade aluminum, which offer high strength and load-bearing capacity, making them suitable for humid environments such as kitchens and bathrooms. Plastic materials, often PVC or PP, are lightweight, cost-effective, and available in a wide range of colors, ideal for hanging lighter items. Resin materials provide excellent durability, water resistance, and wear resistance, allowing for diverse designs that combine aesthetics and practicality.
Metal hooks often undergo brushing or chrome plating to enhance rust resistance and improve texture. Plastic/resin hooks are manufactured through injection molding for mass production. Adhesive-backed hooks utilize pressure-sensitive adhesive technology to ensure reliable attachment, with some variants allowing residue-free removal.
