1. Material composition

Zinc alloy metal door plates are mainly made of high-quality zinc alloy materials, adding appropriate amounts of reinforcing fibers and additives, and are made through precision processing.

2. Manufacturing process

The manufacturing process of zinc alloy metal door plates mainly includes the following steps:

*Smelting: Put zinc alloy materials, reinforcing fibers and other raw materials into a high-temperature smelting furnace and melt them to form a zinc alloy melt.
*Die casting: Pour the zinc alloy melt into the die casting mold to form zinc alloy die castings under high temperature and high pressure.
* Cooling: Put the zinc alloy die-casting parts into the cooling tank to cool, harden and shape.
* Processing: Carry out machining operations such as cutting, drilling, and milling on zinc alloy die-casting parts to make them comply with the shape and size requirements of the house number. * Spray coating: The polished zinc alloy door plate is spray-coated to make it anti-corrosion, anti-oxidation and other functions.
* Polishing: Polish the processed zinc alloy door plate to make its surface smooth and delicate.

3. Product features

Zinc alloy metal door plates have the following characteristics:

* High strength and corrosion resistance: Zinc alloy material has excellent comprehensive properties, can maintain its appearance and quality for a long time, and is suitable for use in various outdoor environments.
* Good anti-aging performance: Zinc alloy materials are not easy to age in the natural environment and can maintain color and luster for a long time.
*Easy to install: There are mounting holes and mounting accessories on the back of the zinc alloy metal door plate, which is convenient for users to install and use.
*Easy maintenance: Just regular cleaning and maintenance, wipe the surface with a soft cloth or wash with a mild detergent.

4. Usage environment

Zinc alloy metal door plates are suitable for various places and fields, such as buildings, office buildings, factories, schools, hospitals, etc., and are suitable for use in various outdoor environments.

5. Installation method

The installation method of zinc alloy metal door plates is as follows:

* According to the installation location and size requirements, select the appropriate mounting hole location on the back of the house number.
* Connect the mounting accessories to the house number and fix it on the mounting hole of the house number with fasteners such as screws.
* Install the house number to the desired location and tighten with screws and other fasteners.

6. Maintenance

In order to maintain the appearance and quality of zinc alloy metal door plates, it is recommended to perform the following maintenance operations regularly:

*Cleaning: Wipe the surface with a soft cloth or clean with a mild detergent. Avoid using cleaning agents containing chemicals such as acids and alkalis.
* Inspection: Regularly check the installation and use of house numbers. If it is found to be loose or damaged, it should be adjusted or replaced in time.
* Anti-corrosion: During use, long-term contact with corrosive substances, such as moisture, salt, etc., should be avoided to avoid affecting the corrosion resistance of the door plate.
* Anti-aging: When zinc alloy materials are exposed to outdoor environments for a long time, their aging may be accelerated, so long-term exposure to harsh environmental conditions should be avoided.
