Hardened steel or boron shackle: The U-shaped part of the lock is made from hardened materials that are highly resistant to cutting, sawing, and drilling.
Solid steel or brass body: The main body is often a solid block of hardened steel, laminated steel, or solid brass. Heavy-duty construction is designed to resist cutting, prying, and impact. Solid steel is tougher, while brass offers superior corrosion resistance for outdoor use.
High-security cylinder: The locking mechanism contains a high-pin-count cylinder (e.g., 4 to 6 pins) to resist picking attempts. In some designs, dual ball bearing locking mechanisms secure the shackle for maximum resistance against prying attacks.
Corrosion and weather protection: For outdoor use, many heavy-duty padlocks are rust-proof and corrosion-resistant. This can include features like an encased body, weather-resistant coatings, or keyway covers to protect the cylinder.
