The LD-325 disc padlock uses a round 304 stainless steel body that shrouds the hardened steel shackle, leaving only a narrow clearance exposed. By concealing most of the shackle inside the disc, the design denies bolt cutters and hacksaws the leverage and access they need, forcing any attack onto the hardened steel itself rather than a vulnerable exposed arc. The 5-pin tumbler cylinder resists picking and raking, while the all-stainless construction shrugs off rain, salt, and humidity that quickly rust ordinary plated locks.

Because the body is machined from 304 stainless steel rather than zinc alloy with a coating, corrosion protection is integral rather than superficial. Even when the surface is scratched during years of outdoor service, the lock continues to resist rust, making it especially well suited to coastal, marine, and high-humidity environments. The compact round profile also minimizes snagging and rotation, so the lock stays correctly oriented on hasps, chains, and disc-brake applications where a bulky body would be impractical.

The LD-325 is offered in body diameters of 60mm, 70mm, and 80mm with shackle diameters from 8mm to 10mm and clearance of 15-25mm, covering light-duty lockers up to heavy gates and containers. Color and finish options include Silver, Stainless steel, Black, and Chrome, giving distributors a range that suits both utility and retail display. Each lock ships with two to three brass-cut keys and supports keyed-different, keyed-alike, and master key configurations for multi-site and fleet programs.

For wholesale buyers, the LD-325 supports full OEM customization including logo laser engraving, custom shackle dimensions, tailored finishes, and branded packaging. With an MOQ of 200 pieces, mixed-order flexibility, and CE/RoHS/ISO 9001 compliance, it is an ideal stock item for hardware distributors, self-storage suppliers, and e-commerce sellers focused on durable outdoor security.
