Nowadays, many people will choose imitation copper doors. Most of the imitation copper doors on the market are iron doors, and the appearance of the exterior is still acceptable. The imitation copper doors used in previous years are produced by cold-rolled sheets. After one or two years, rust-painting will occur. With the innovation of the market, some manufacturers will use galvanized steel sheets because of the surface of galvanized steel sheets. The handling requirements are relatively high and are not prone to rust. Recently, the steel plate door has been lacquered, so the copper-aluminum door appears. What are the differences between the copper-aluminum door and the imitation copper door? The life and price of high-simulation copper gates and general imitation copper gates are quite different. The common imitation copper gates are low in cost, and are easily pulverized and faded by the influence of ultraviolet radiation and wind and rain. However, the high-simulation copper door uses UV-resistant acrylic, weather-resistant, and the paint has been surface treated for long-lasting use without discoloration. The copper-aluminum door looks at the color. The common imitation copper door knowledge adds some copper powder to the copper plastic powder to carry out electrostatic spraying to reduce the adhesion with the board. This makes it easy to powder the paint and the color will appear uneven. The feeling of getting up will be rough. The high-simulation copper door is made of UV-resistant acrylic, with strong metal and uniform color. There are still many ways to distinguish between copper-like and copper-aluminum doors. Now some copper-aluminum doors are relatively small in size and are sprayed according to the requirements of the sale.
