Inferior product
Using inferior zinc alloy to recycle materials, and cutting corners to reduce costs, the structure is loose, the weight is light, and the feel is light. Low-cost brightener is used in electroplating, which has loose structure, poor adhesion and dull and whitish luster. Because chromium plating directly on zinc alloy is easy to rust, wear, blister and peel off in a short time. The coating thickness is less than 3 microns, and there are many scratches and burrs on the surface of the coating.
Excellent product
Made of molded copper, high-quality zinc alloy or titanium alloy, with compact structure, heavy weight and thick handle. Pure copper is the best raw material, the wall thickness of copper tube is generally 0.6-0.8m, and the electroplated layer is bright, with good adhesion, compact structure, uniform coating, crisp color surface, and the coating thickness is generally above 6 microns.
Identification packaging
The raw materials of the packaging box are inferior, the printing is rough and the trademark is vague. Generally, the manufacturer is not indicated on the packaging and inner box, or even the "three noes" products. The packaging design is beautiful and the trademark is clear and eye-catching. Generally, the manufacturer and detailed address will be indicated, and there are quality inspection books and installation instructions in the inner box.
