Definition of DX53D galvanized steel coil

DX53D is a grade of cold-rolled low-carbon steel coil  and strip, conforming to the EN 10346 (European standard) or GB/T 2518 (Chinese standard, corresponding to the grade DC53D).

Core performance

Mechanical Properties

Tensile strength (σb) 310-450 MPa, yield strength (σs) ≤280 MPa, elongation (A80mm) ≥34%, high plasticity and low yield strength, suitable for complex deep drawing.

Corrosion Resistance

The zinc layer preferentially corrodes, forming a protective mechanism that prevents rusting. It can withstand long-term use in normal atmosphere and slightly humid environments, with a lifespan 3-5 times longer than ordinary cold-rolled steel.

Surface Properties

The surface is clean and scratch-free, and supports a variety of surface finishes, including embossing, passivation, and fingerprint resistance. It can be used directly or undergo secondary processing such as painting or lamination. The hot-dip galvanized layer resists peeling during bending and stamping.

Formability

“Grade 53” is a deep-drawing grade that can withstand complex processes such as deep drawing and bulging, making it a typical example of “easy-to-form” galvanized steel.

Application

Construction

Ventilation ducts, decorative panels, and color-coated coil substrates. Steel beams and columns for high-rise buildings, as well as roof and wall panels, are also used.

Automotive

Primarily used to manufacture automotive parts such as door inner panels, longitudinal beams, wheel arches, chassis, fuel tanks, instrument panel brackets, and door inner panels.

Home Appliances

Commonly used in the production of housings for appliances such as refrigerators, washing machines, and air conditioners, as well as microwave oven inner containers and oven brackets.

Industrial Equipment and Machinery

Used to manufacture housings, brackets, and protective covers for industrial equipment, as well as precision parts such as gears, bearings, and housings.

Selection Recommendations

Select the zinc layer thickness according to the application

• Indoor environments: Choose a zinc coating thickness of 40-80g/m².
• Architectural applications: For general atmospheric environments, a zinc coating thickness of 60-120g/m² is recommended. For acid rain and coastal areas with high salinity, a zinc coating thickness of 180-275g/m² is recommended.
• Automotive industry: For vehicle exterior panels, 120-180g/m²; for chassis components, 180-275g/m².
• Home appliance industry: For appliance exteriors, 40-100g/m². For humid environments, such as washing machine drums, 120-180g/m² is recommended.
• Industrial equipment and machinery: For general industrial environments, 80-120g/m² is recommended. For industrial environments with severe corrosion, such as chemical plants, a zinc coating thickness of 180-275g/m² is recommended.
• Other applications: For fencing and guardrails, 80-120g/m² is sufficient. For solar panel structures, a zinc coating thickness of 60-180g/m² is recommended.

Focus on the surface treatment process

• Anti-fingerprint treatment: Suitable for electronic component housings to prevent fingerprint residue.
• Passivation treatment: Improves the corrosion resistance of the zinc layer and extends its service life.
• Environmental protection: Choose a chromium-free or water-based passivation process, compliant with RoHS standards.

Verify supplier qualifications

• Prioritize suppliers that offer custom processing (such as slitting, flattening, and punching) to reduce secondary processing costs.
• Select reputable manufacturers with extensive export experience and prompt delivery.
