When choosing a box for outdoor LED display, sheet metal box and die-cast aluminum box have their own characteristics and advantages, and the specific choice should be decided according to actual needs and budget. Here's a detailed analysis of the two cabinet types:
Sheet metal box
Merit:
1. Strong and durable: The sheet metal box is usually made of sheet metal through stamping, bending and other processes, which has high strength and rigidity, and can resist external impact and extrusion.
2. Strong customizability: The sheet metal box can be customized according to actual needs to meet the requirements of various sizes and shapes.
3. Protective performance: Through surface treatment such as spraying or galvanizing, the sheet metal box has good anti-corrosion, moisture-proof, dust-proof and other properties, and can adapt to complex outdoor environments.
Shortcoming:
1. Heavy weight: Since the sheet metal box is made of metal sheets, its weight is relatively large, which is not convenient for transportation and installation.
2. Higher cost: Compared with die-cast aluminum box, the manufacturing cost of sheet metal box is higher.
Die-cast aluminium enclosure
Merit:
1. Lightweight design: The die-casting aluminum box is made of aluminum alloy material processed by die-casting technology, which has a low weight and is easy to transport and install.
2. Good heat dissipation performance: Die-cast aluminum has good thermal conductivity, which can effectively dissipate the heat generated by the LED display and improve the stability and life of the screen.
3. Beautiful appearance: The appearance of the die-cast aluminum box is smooth and consistent, and it has a good overall appearance.
4. Lower cost: Compared with sheet metal box, die-cast aluminum box has lower production cost and has a price advantage.
Shortcoming:
1. Relatively low strength: Compared to sheet metal boxes, die-cast aluminum cabinets have lower strength and may not be suitable for locations that require high impact resistance.
2. Poor corrosion resistance: Die-cast aluminum material is susceptible to oxidation and corrosion, which may affect the service life in special environments.
Summary
* If you have high requirements for the protection performance and robustness of the display, and the budget is sufficient, you can choose a sheet metal cabinet.
* If you have high requirements for lightweight, heat dissipation performance and cost, and the use environment is relatively good, you can choose die-cast aluminum cabinet.
In the actual selection, other factors need to be considered, such as the size of the display, weight, installation environment, etc. It is recommended to conduct a comprehensive evaluation according to the specific situation and choose the most suitable cabinet type.
