Wholesale Disc Combination Padlock Supplier, OEM/ODM Factory

The Disc Combination Padlock is a round, key-free lock with a concealed built-in shackle, made to resist cutting and forced prying. Choose zinc alloy when you want cost efficiency for light and medium security, and choose 201 or 304 stainless steel when the lock will sit in a high-humidity outdoor setting. Zhejiang Rongtao Hardware Products Co., Ltd. is a wholesale Disc Combination Padlock supplier and an OEM/ODM Disc Combination Padlock factory in Yiwu, Zhejiang, and it offers both materials in a standard 70 x 70 x 20 mm body with a 9 mm hardened steel shackle.

Why the Disc Design Resists Cutting and Prying

A disc padlock has an integrated round body, and the shackle sits inside it instead of hanging outside like a classic U-shaped shackle. With so little metal exposed, cutting tools and pry bars have very little to grip. This concealed built-in shackle is the main reason the Disc Combination Padlock is chosen for storage cabinets, gym lockers, school storage boxes, and luggage cases.

The lock opens with combination wheels that turn smoothly and carry clear, visible number markings. Both models from Zhejiang Rongtao Hardware use a 4-digit combination and ship with no keys at all, so there is nothing to lose, copy, or hand out to every user.

Two Materials for Two Kinds of Buyers

Rongtao Hardware focuses its Disc Combination Padlock range on two materials, and each one is built for a different job. The table of specifications comes later, so the panels below show what sets the two models apart in practice.

Zinc Alloy Disc Combination Padlock

High-pressure die-cast integrated lock body with a dense internal structure and no gaps
Smoothly polished surface with no burrs
Multi-layer powder coating that resists fading and oxidation
Multi-wheel linkage precision combination components
Standard sizes in sufficient stock

Stainless Steel Disc Combination Padlock

Available in 201 and 304 stainless steel
Rust and corrosion resistance far superior to alloy models
Brushed polishing for long-lasting gloss
Supports password reset
Export quality, with multiple quality inspection certifications

The zinc alloy model suits home, commercial, and small industrial storage where light to medium security is enough, indoors or outdoors. The stainless steel model is the better fit for harsh, high-humidity outdoor environments. Zhejiang Rongtao Hardware Products Co., Ltd. states that the zinc alloy production process complies with international export quality inspection standards, which matters to importers who need consistent batches. To keep raw materials under strict control, the company also set up Yiwu Rongtao Renewable Resources Co., Ltd. for its padlock production.

Technical Specifications Side by Side

Both models share the same body size and shackle, so buyers can mix zinc alloy and stainless steel locks in one order without changing hasp or cabinet designs.

For a school or gym, one zinc alloy Disc Combination Padlock per locker removes key management completely. For a warehouse or a logistics operation with outdoor exposure, the stainless steel version keeps its finish in humid conditions. Rongtao Hardware supplies both from the same 18,000 sq m factory, where about 100 employees work, which simplifies purchasing for wholesale buyers.

Disc Combination Padlock FAQ

Does a disc combination padlock come with keys?

No. Both the zinc alloy and stainless steel models open only with a 4-digit combination, so there are no keys to lose or duplicate.

What size is the disc combination padlock?

Both models have a 70 x 70 x 20 mm lock body and a 9 mm hardened steel shackle.

What is the difference between zinc alloy and stainless steel disc padlocks?

Zinc alloy is a die-cast body with powder coating that balances cost and security. Stainless steel resists rust and corrosion far better than alloy models and is made for high-humidity outdoor use.

Which stainless steel grades are available?

Rongtao Hardware offers the stainless steel Disc Combination Padlock in 201 and 304 stainless steel.

Can I put my brand logo on the padlock?
