What a Concealed Shackle Actually Protects Against
The defining feature of this padlock is the concealed shackle design, which provides dual protection against rust and prying at the same time, according to the product description. Since the shackle sits behind the round stainless steel body rather than above it, there is almost no exposed metal for a bolt cutter or pry bar to reach, while the stainless steel body itself resists corrosion in humid or salt-heavy air. Zhejiang Rongtao Hardware Products Co., Ltd. builds both the 201 and 304 versions on this same body shape, so the anti-prying benefit is not limited to one grade.
201 vs 304: Matching the Grade to the Site
Buyers sourcing from a Wholesale Stainless Steel Disc Padlock Supplier still need to pick the right grade for the job, and Zhejiang Rongtao Hardware Products Co., Ltd. keeps both options in active production.

Lock Body and Shackle Construction
The product is described as full stainless steel material at the series level, and the detailed specification sheet for both grades lists the lock body as 201 or 304 stainless steel with the shackle built from A3 steel. Zhejiang Rongtao Hardware Products Co., Ltd. stamps the outer body as one integrated piece and pairs it with a brass lock cylinder, so the parts that a buyer actually touches and sees, the disc-shaped shell and the polished finish, are the stainless steel components the padlock is sold on.
Lock Body
201 or 304 stainless steel, stamped as one integrated disc-shaped piece with a polished finish.
Shackle
A3 steel, hidden behind the lock body for anti-sawing and anti-prying protection.
Cylinder
Brass lock cylinder for smooth, precision unlocking with a low mutual-opening rate.
Specifications
Both grades share the same shackle material, size range, and packaging structure, which is what allows a wholesale order to mix 201 and 304 units without changing the ordering format.

Sourcing From a Factory-Direct Supplier
Zhejiang Rongtao Hardware Products Co., Ltd. describes itself as a source factory for locks with over 30 years of experience, built on Yiwu Shengping Lock Factory, and positions itself as a trusted supplier for overseas buyers rather than a trading intermediary. The company states a commitment to integrity and on-time delivery, which is the basis it gives for the trust it has built with clients worldwide, and it also supports customized designs for buyers who want a disc padlock built around their own specifications rather than a fixed catalog item.
For a Wholesale Stainless Steel Disc Padlock Supplier relationship, working factory-direct means the same team that stamps the lock body, fits the A3 steel shackle, and applies the polished finish is also the team confirming laser marking and packaging on an OEM order, rather than the request passing through a separate trading company.
