Doors and windows in buildings are made from a variety of materials, such as PVC, aluminum alloy, stainless steel, and color steel. The hardware used for these doors and windows varies depending on the material. There are three main types of window and door opening methods: sliding, hinged, and outward-opening. Therefore, the hardware and accessories must be compatible with the specific type of opening. In this article, we will introduce some common door and window hardware components and provide tips for purchasing them.
One essential component is the sealing strip. It is placed between the door panel and frame to reduce noise when closing the door. Without it, the impact can reach up to 120 decibels, which can be harmful to health. High-quality sealing strips are non-reactive to paint, ensuring a smooth finish. They also help absorb shocks, reduce noise, improve insulation, and prevent moisture from entering.
Hinges are used for hinged doors and windows. When buying, consumers should check the material—common options include copper, electroplated copper, stainless steel, and aluminum alloy. Avoid hinges made from zinc alloy casting, as they tend to be less durable.
A strong hinge with three points of contact is recommended. These hinges offer better strength, easier assembly and disassembly, smooth operation, and even include a silencing feature for quieter movement.
Sliding supports are used to control the movement and positioning of casement windows. When purchasing, choose stainless steel models. The surface should be free of scratches, sharp edges, or burrs. A slight resistance during sliding indicates good quality.
Pulleys are responsible for moving sliding doors and windows horizontally. When selecting pulleys, pay attention to the material of the frame and whether it uses needle roller bearings or ball bearings. For heavy sliding doors, use specialized door pulleys rather than those designed for windows.
Handles are used on casement windows to press the sash against the frame, ensuring a tight seal. Check that the handle has a smooth, burr-free surface, even coating, and appropriate weight for stability.
Half-moon locks are commonly used on window sashes. Opt for ones made from stainless steel or aluminum alloy for better durability. A good lock should operate smoothly and not feel cheap or stiff.
Decorative hardware should have an attractive appearance. When purchasing, inspect for any defects, check the gloss, and ensure the surface feels smooth to the touch.
It’s important to choose hardware with good sealing, smooth operation, and ease of use. Test the opening and closing several times before purchasing to ensure flexibility and convenience.
Door hinges come in two types: removable and fixed. They also have different cover styles, such as large-radius, medium-radius, and straight. When checking hinges, look for a smooth surface and good spring return. A properly functioning hinge should open to at least 95 degrees, and the spring should remain intact after being pressed from both sides.
Drawer slides come in two or three rails. When selecting, check the finish and plating, as well as the gap and strength of the load-bearing wheels. Choose wheels that rotate smoothly and wear evenly for long-lasting performance.

Application for Guage rod
As an important accessory for railroad tracks, rail gauge tie rod helps to improve the rails` lateral stability and also the ability to keep rail distance. There are some railways that with track circuit, then it should use the insulated rail gauge rod which adopts high insulation resistance material to separate the circuit between two rails apart. Rail gauge may deviated if gauge tie rod is serious lacked, it may cause derailment or even overturned when the train passing by.
