亜鉛メッキクレーンフック腐食耐性

In industries where corrosion compromises safety and productivity, our Hot-Dip Galvanized Crane Hook delivers unmatched protection and reliability. Designed for the harshest conditions—from offshore platforms to chemical plants—this hook combines military-grade corrosion resistance with brute strength, ensuring your lifting operations never falter.

Why Galvanized? The Science of Survival

Unlike painted or electroplated hooks, our hot-dip galvanizing process (compliant with ISO 1461) submerges the forged steel hook in molten zinc at 450°C. This creates a metallurgical bond that:

• 1. Forms a triple-layer barrier (zinc-iron alloy + pure zinc) against rust, acids, and saltwater.
• 2. Provides sacrificial anode protection: Zinc corrodes first, preserving the steel even if scratched.
• 3. Withstands 1,000+ hours of salt spray testing (ASTM B117) without red rust.

重要な機能 & Engineering Advantages

• 1. Extreme Corrosion Resistance

  • Zinc coating thickness: 85–120μm (3–5x thicker than electroplating).
  • Resists pH 5–12 chemicals, UV degradation, and abrasive particulates.

• 2. Unrivaled Strength & 安全性

  • Forged from Grade 100/Alloy Steel (minimum tensile strength: 1,000 MPa).
  • Load-tested at 200% wllの (作業負荷制限).
  • Non-sparking design for explosive atmospheres (ATEX optional).

• 3. Zero-Maintenance Durability

  • Service life: 25+ years in coastal/marine settings (per ISO 9224 corrosion category C5).
  • No recoating or inspections beyond standard rigging checks.

• 4. Intelligent Design

  • Self-lubricating swivel bearing (360° rotation under load).
  • Radiused throat geometry reduces wire rope wear by 40%.
  • Optional safety latch with positive-lock mechanism.
