Bolt Type Shackle Choose
I. Material
1. Forged Carbon Steel / Alloy Steel
-Standard Grade: High-strength forged carbon steel, quenched & tempered
-Premium Grade: Alloy steel (e.g., G209/G2130 series), heat-treated for maximum toughness
-Surface Treatment: Hot-dip galvanized / electro-galvanized for anti-corrosion
2. Stainless Steel (304 / 316)
-304 Stainless Steel: Good corrosion resistance, ideal for general outdoor, industrial, and mildly corrosive environments
-316 Stainless Steel (Marine Grade): Excellent resistance to saltwater, chemicals, and rust; perfect for marine, offshore, and coastal applications
-Finish: Bright polished or electropolished
3. Other Special Materials
-Titanium Alloy: Ultra-lightweight, high strength, used in aerospace, high-end marine sports
