Galvanized mounting plates are metal sheets treated with hot-dip galvanizing or electro-galvanizing processes, widely used in electrical cabinets, mechanical brackets, architectural structures, and more. Their features revolve around corrosion resistance, structural strength, and ease of installation. The following analysis will be conducted from dimensions such as technical characteristics, application advantages, and selection points.
Technical Specifications of Galvanized Installation Plate
Corrosion resistance properties
Hot-Dip Galvanized: Steel plates are immersed in molten zinc (450℃~480℃), forming a zinc-iron alloy layer with a thickness of ≥65μm, offering corrosion resistance for over 20 years (industrial environment).
Electroplated zinc: Deposits a zinc layer (thickness 5μm~25μm) through electrolysis, suitable for indoor environments, has weaker corrosion resistance than hot-dipped galvanized, but higher surface smoothness.
Case: Marine platform brackets are equipped with hot-dip galvanized mounting plates, passed 1000 hours of salt spray testing without rust, and have a lifespan five times that of ordinary carbon steel plates.
Degree and structural stability
Base Material Strength: Typically uses carbon steel Q235B or Q345B, with yield strength ≥235MPa and tensile strength ≥375MPa, capable of supporting heavy-duty equipment (such as switchgear, motors).
Corrosion Resistance: Zinc coating hardness HV≥70, enhances surface wear resistance, preventing local corrosion caused by scratches during installation.
Data: Hot-dip galvanized steel sheets exhibit less than 0.1% deformation within the temperature range of -20℃ to +200℃, suitable for extreme environments.
Conductivity and electromagnetic shielding
Zinc coating conductivity: approximate resistivity of 5.9μΩ·cm, suitable for electrical cabinet grounding systems, ensuring safe current conduction.
Electromagnetic Shielding: The galvanized layer reflects electromagnetic waves (screening effectiveness ≥ 40dB at frequencies < 30MHz), reducing interference between devices.
Application: Zinc coating is required for the data center server cabinet mounting plate to prevent electromagnetic radiation from affecting server operation.
Ease of processing and installation
Easy to cut and punch: The galvanized layer does not affect the mechanical processing properties of the steel, allowing for forming through methods such as laser cutting and stamping.
Standard Sizes: Common thickness 1.5mm to 3.0mm, width 600mm to 1250mm, length customizable, fits most cabinet structures.
Installation Methods: Supports bolt fastening, welding, or clip connection, compatible with M4~M12 threaded holes, installation efficiency increased by 30%.
