Engineered Chain Solutions for Global Industries
Different jobs need different chains. Playground chains need smooth surfaces and rust protection. Hoist chains need exact dimensions and zero jamming. Rigging chains need high strength and strict safety ratings.
We supply application-specific chains for B2B buyers, OEM factories, and distributors.
Outdoor Leisure & Playground Chains
Playground chains face rain, sun, UV, and constant hand contact.
Smooth Welds: We grind all weld seams smooth to stop scratches and pinches.
Safe Surface Finishes: Hot-Dip Galvanized ($>65\mu\text{m}$ zinc) or soft PVC coating (RoHS / REACH compliant).
Ready-to-Install: Custom pre-cut lengths with quick connectors.
Hand Chain Hoist Chains (Zero-Jamming)
Hoist chains run over pocket wheels. Small size errors cause jamming and equipment damage.
Exact Pitch Dimensions: Pitch size tolerance controlled within $\pm 0.2\text{mm}$.
Deep Case Hardening: High surface hardness stops link wear under heavy loads.
Tough Steel Core: Specialized heat treatment prevents brittle snapping.
Industrial Rigging & Lifting Chains
Lifting operations need strict load ratings and safety certificates to prevent accidents.
Clear Load Stamps: WLL stamped on chain links every 1 meter.
4:1 Safety Factor: Breaking load is 4 times the rated Working Load Limit.
100% Tested: Every batch is proof-load tested to 2.5x WLL before packing.
Certificates Included: Shipped with EN 10204 3.1 Material Test Reports (MTR).
Vehicle Snow & Anti-Slip Chains
Tire chains face high friction on asphalt, ice, mud, and rocks.
Hardened Surface (58-62 HRC): Resists asphalt wear and extends service life.
Shock-Resistant Core: Flexible inner core prevents breaking under hard shocks.
Better Road Grip: Square links and twisted links improve traction on ice.
Marine & Coastal Environment Chains
Ocean water corrodes regular steel fast. Marine applications need high corrosion resistance.
316 / 316L Stainless Steel: Resists pitting corrosion in saltwater.
Heavy Zinc Coating: Hot-Dip Galvanized zinc layer up to $85\mu\text{m}$ for long service life.
Tested Quality: Passes 500+ hours salt spray test (ASTM B117).
Agricultural & Farming Chains
Farm chains work in mud, dirt, rain, and heavy machinery loads.
High Fatigue Resistance: Handles repeated shock loads from harvesters and farm machines.
Chemical Protection: Thick zinc layer resists rust from fertilizer and wet soil.
