FAQ

• Q

  How to understand the specifications and models of hardware products? How to choose the appropriate specifications?
  A

  The specifications and models of hardware products usually indicate key parameters such as size, precision, load-bearing capacity, and interface type (for example, "M8×20" for screws indicates a thread diameter of 8mm and a length of 20mm; "4 inches" for hinges indicates a hinge edge length of about 10cm). When selecting specifications, it is necessary to consider the actual needs of the usage scenario: for example, small-sized screws can be selected for fixing lightweight boards, and large-sized hinges are required for doors and windows with high load-bearing capacity; meanwhile, it is necessary to match the corresponding interfaces and hole diameters to avoid incompatibility and unusability. If you are unsure, you can provide details of the usage scenario and consult relevant professionals.

• Q

  What are the main materials used for hardware accessories? Are there differences in the applicable scenarios for different materials?
  A

  Common materials for hardware accessories include stainless steel, carbon steel, aluminum alloy, copper, zinc alloy, etc. Different materials have distinct differences in their applicable scenarios. Stainless steel is corrosion-resistant and not prone to rust, making it suitable for humid environments (such as kitchens, bathrooms, and outdoor spaces); carbon steel has high hardness, making it suitable for scenarios where it needs to withstand significant force (such as mechanical connections and building fixation); aluminum alloy is lightweight and has good thermal conductivity, making it suitable for scenarios where weight is a consideration (such as doors and windows, lightweight equipment); copper has excellent electrical and thermal conductivity, and is commonly used in electrical and sanitary-related accessories; zinc alloy is easy to die-cast and is often used for decorative hardware. The appropriate material can be selected based on the usage environment and force requirements.

• Q

  Are there unified quality standards for hardware products?
  A

  The hardware industry has clear national and industry quality standards, with different standards corresponding to different product categories (such as GB/T 3098 series standards for fasteners and GB/T 9305 series standards for door and window hardware). Compliant hardware products are produced in accordance with the corresponding standards and undergo basic quality inspection before leaving the factory to ensure that product performance, dimensions, and other aspects meet usage requirements. It is recommended to prioritize products that comply with national standards when purchasing, in order to ensure usage safety and durability.
• Q

  What is the difference between decorative hardware and functional hardware?
  A

  The core purposes of the two are different, and there is no superiority or inferiority between them. Decorative hardware primarily aims for aesthetics and embellishment, with common categories such as handles, decorative nails, and decorative hangings, focusing on appearance design and material texture, and adapting to the overall decoration style; functional hardware centers on achieving specific functionalities, with common categories such as hinges, slide rails, locks, screws, wrenches, etc., focusing on load-bearing capacity, wear resistance, and durability, directly affecting the user experience and safety. In practical applications, the two are often used in combination.
• Q

  How to prolong the service life of hardware accessories used outdoors?
  A

  Outdoor hardware accessories are susceptible to the effects of wind, rain, humidity, and ultraviolet radiation. To extend their service life, the following measures can be taken: 

  1. Preferentially choose products made of corrosion-resistant materials such as stainless steel and hot-dip galvanized steel;
  2. Apply a rust-proof coating (such as rust-proof paint or rust-proof oil) on the surface before installation to enhance protection;
  3. Regularly clean the surface to remove dust, stains, and accumulated water, and avoid the residue of corrosive substances (such as saltwater, acid and alkali solutions);
  4. If rust or looseness is found on the surface, promptly address it (such as rust removal and fastening), and replace it if the damage is severe.
