I. Core Features

1. Excellent Mechanical Properties

o Tensile Strength: ≥550 MPa (common galvanized sheet is typically 370-450 MPa), with some high-strength products exceeding 700 MPa.

o Yield Strength: ≥300 MPa, suitable for load-bearing structures (such as building trusses and automotive chassis).

o Elongation: ≥18%, balancing strength and formability, suitable for cold bending, stamping, and other processes.

2. Improved Corrosion Resistance

o Zinc Coating Thickness: Standard coating is 120 g/m2, and high-strength galvanized sheet can be customized up to 200 g/m2 (as in the case of West African pipe piles), resistant to the high-salt and humid environment of mangroves.

o Cut Protection: Cold zinc spraying provides secondary corrosion protection for cut edges, extending service life to 30 years (third-party certified).

3. Processing Adaptability

o Formability: Supports stamping of complex shapes (such as automotive B-pillar reinforcements), with an angular tolerance of ±0.5° (see Vietnamese furniture example). Weldability: Compatible with laser welding and resistance welding, automatic zinc coating compensation technology in the weld zone reduces corrosion risk.

II. Typical Application Scenarios

1. Building Structures

Requirements: High load-bearing capacity and weather resistance (e.g., beach villas, chemical plants).

Solution: 200g/㎡ zinc coating + cold-spray zinc cut-out treatment, passing ISO 12944 C5 corrosion test, replacing traditional stainless steel to reduce costs.

2. Automotive Manufacturing

Requirements: Balanced lightweighting and safety (e.g., new energy battery packs, chassis crossmembers).

Solution: High-strength galvanized steel (550MPa grade) replaces ordinary steel, reducing weight by 15% while meeting collision safety standards.

3. Appliance and Equipment Housings

Requirements: Fingerprint and scratch resistance (e.g., outdoor air conditioner housings, agricultural machinery housings).

Solution: Apply an anti-fingerprint agent to the zinc coating, combined with pearl cotton and wrap film for protection (refer to Vietnam case), ensuring zero scratches during transportation. 4. Energy and Infrastructure Engineering

Requirements: High-temperature and high-pressure resistance (e.g., oil drilling platforms and photovoltaic racks).

Solution: 35CrMo alloy galvanized sheet, heat-resistant to 500°C, certified for a 30-year lifespan (West African pipe pile case).
