Good hardware pendants are generally environmentally friendly copper and chrome plated. As long as the electroplating process is in place, it will not rust after long-term use. However, zinc alloy, 20 1 stainless steel, aluminum alloy and even stainless iron are mostly of poor quality, and obvious rust spots or bending fractures will appear after a few months.

Careful surface treatment

Inferior products have dull luster, white coating and many defects (scratches, burrs and black spots) on the surface. High-quality hardware products have smooth coating, obvious defects are not easy to find on the surface, and the luster is bright and uniform.

Look at the signs and packaging.

The low-end brand logos is mostly screen printed on the product, or there is no trademark on the product at all. The outer packaging trademark is vague, the handwriting is unclear, the packaging box is loose, and there is no manufacturer. The brand logo of high-quality products is generally marked by laser, which is clear and tidy. The outer packaging design is beautiful and firm, and the inner box has installation instructions, inspection marks, warranty cards, etc. The manufacturer is clear and the trademark is striking.

Maximum weight of horse pack

Inferior products, feel frivolous. Some merchants may claim to be copper, but they actually use much lighter zinc alloy materials, which can be distinguished by weight. In addition, products of the same size and material tend to be denser, thicker and more durable.
