Talking about the main classification and purchase skills of hardware

The classification and purchasing methods of hardware products are typically divided into common and special hardware based on their functions. Common hardware includes hinges, slide rails, decorative handles, and locks, which are categorized by installation method. Special hardware is further split into bathroom hardware and kitchen-specific accessories, such as pendant units, depending on where they are installed. When purchasing hardware, it's important to select components with good sealing performance, such as hinges, slide rails, and locks. The flexibility and smoothness of the lock should also be considered—test it by inserting and removing the key multiple times to ensure it operates smoothly. For decorative hardware, choose pieces that have an attractive appearance and solid performance. Skirting boards are often overlooked but play a critical role in protecting the base of kitchen cabinets. Since they are closest to the ground, moisture can cause them to swell or mold. There are two main types: wooden skirting boards and matte metal ones. Wooden options are usually made from leftover materials, making them more cost-effective. However, due to their proximity to the floor, they are prone to water absorption, which can lead to damage over time. Slide rails come in two types: two-track and three-track systems. When selecting these, pay attention to the finish quality, the gap between parts, and the strength of the load wheels, as these factors affect the smoothness and noise level during drawer operation. Steel trays and cutlery plates are essential for kitchen cabinets. They are accurate in size, standardized, easy to clean, and resistant to deformation and pollution. Widely used in developed countries like Germany, the U.S., and Japan, they significantly improve the functionality of drawers. When inspecting a kitchen cabinet, open each drawer to check if it uses steel trays and cutlery plates, as this indicates higher quality and better construction. Handles come in various materials, including zinc alloy, copper, aluminum, stainless steel, plastic, wood, and ceramics. They are available in different shapes and colors to match furniture styles. Electroplated or electrostatically painted handles offer durability and resistance to wear and corrosion. Additionally, they must be strong enough to withstand pulling forces—ideally over 6 kg. Hinges are another key component, with three main types: door hinges, drawer guides, and cabinet hinges. Door hinges are commonly made of copper or stainless steel. Standard sizes include 10cm x 3cm and 10cm x 4cm, with Shaft diameters ranging from 1.1cm to 1.3cm and wall thickness between 2.5mm and 3mm. When choosing hinges, ensure they open quietly and smoothly, ideally with ball bearings inside the shaft for improved performance. Cabinet door hinges are divided into detachable and non-detachable types. The cover parts come in large, medium, and straight bends, with medium bends being the most common. Besides checking the surface finish and smoothness, pay attention to the hinge spring’s reset function. A quality hinge should open up to 95 degrees and maintain stability when pressed from both sides, ensuring the internal spring remains intact and strong.
