Display stand materials are usually mainly aluminum alloy, carbon steel and plastic three. Carbon steel is the best material, durable and the most expensive. Aluminum alloy materials are relatively popular, and most brackets on the market are made of aluminum alloys, which are very cost-effective. Plastic materials are the cheapest, but have a relatively short service life. Personally, it is not recommended to buy plastic materials. https://www.ccnxd.com/products/
