There are various material options for the anti-corrosion layer of outdoor LED screen sheet metal cabinets, depending on the manufacturer's design and engineering needs.
Referring to the relevant information, we can list and describe several common anti-corrosion layer materials and their characteristics:
1. Hot-dip galvanizing (hot-dip galvanizing/hot-dip galvanizing):
Principle: Hot-dip galvanizing is an effective way of metal anti-corrosion, which produces an alloy layer by reacting the molten metal with the iron matrix, so that the matrix and the coating are combined.
Features: The hot-dip galvanized layer is generally thicker, with excellent anti-corrosion performance, and can resist corrosion in most outdoor environments.
Application: Hot-dip galvanized pipe is usually used in outdoor LED display as a steel structure stress installation hardware, because it has quite corrosion-resistant characteristics.
2. Cold galvanizing (electro-galvanizing):
Principle: Cold galvanization is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other materials.
Features: The thickness of the electro-galvanized layer is generally only 20~30μm, and the anti-corrosion performance is weaker than that of hot-dip galvanizing, but the cost is low.
Application: Cold galvanized square tube is often used for indoor installation of LED full-color display structural frames, as it can provide a smooth surface for easy installation of LED modules.
3. Stainless steel:
Principle: Stainless steel itself has anti-rust and anti-corrosion properties, and usually the surface is not specially treated.
Features: Stainless steel has excellent corrosion resistance, solid and durable structure, is not easy to scale, and is easy to clean.
Application: Stainless steel is also commonly used in sheet metal cabinets and edging decorative frames for outdoor LED screens, because it has luxury and gorgeous decoration.
4. Other anti-corrosion coatings:
Principle: In addition to the above-mentioned metal plating, various anti-corrosion coatings (such as paints, epoxy coatings, etc.) can also be used as anti-corrosion layers.
Features: The anti-corrosion coating can be selected with different thicknesses, colors and anti-corrosion grades according to needs.
Application: Anti-corrosion coating is widely used for anti-corrosion protection of various outdoor equipment, including sheet metal cabinets for LED screens.
Summary:
The anti-corrosion layer materials of outdoor LED screen sheet metal cabinets mainly include hot-dip galvanizing, cold-dip galvanizing, stainless steel and various anti-corrosion coatings. Among them, hot-dip galvanizing is often used in outdoor environments because of its excellent anti-corrosion properties; Cold galvanizing is more used in indoor environments; Stainless steel is also commonly used in sheet metal cabinets and decorative frames of outdoor LED screens because of its luxury and corrosion resistance; Anti-corrosion coatings, on the other hand, are selected and applied according to specific needs. When choosing the material of the anti-corrosion layer, the use environment, cost, maintenance convenience and other factors of the equipment should be fully considered.
