LD-025 Hardened Steel Security Chain Padlock Set | Factory Wholesale Supplier

This hardened steel security chain padlock set provides the highest level of portable security for motorcycles, bicycles, and valuable equipment that cannot be compromised by lightweight cable locks. The hardened alloy steel chain links at HRC 50-58 resist bolt cutters, hacksaws, and leverage attacks that defeat ordinary chains within seconds.

The matching brass body padlock features a protected shackle design that resists hammering and pry bar attacks, with the brass cylinder providing 5+ years of corrosion-free outdoor operation. The long chain lengths from 1000mm to 2000mm wrap through wheels, frames, and ground anchor points for multi-point security. The keyed-alike option allows fleet operators to secure multiple vehicles with a single key, simplifying management for delivery services and bike share programs. The weatherproof cover cap seals the padlock keyway against rain and road salt. OEM branding, custom chain lengths, and motion-sensor alarm padlock options support wholesale distribution for security retailers and industrial suppliers.
