Disc padlocks for self storage units
A disc padlock protects the shackle inside a hardened body, which makes it far harder to attack with bolt cutters than a standard padlock. For storage units that means less theft risk — and less time spent on unit security.
Choose your configuration
Five decisions shape a disc padlock order — key system, stainless grade, body and shackle size, marking and packaging.
- Key system
- Keyed alike · keyed different · master key
One key per group, one key per unit, or a tenant key plus a manager key. - Material
- SS201 · SS304
SS201 for indoor units and covered corridors. SS304 for exposed and coastal sites. - Body / shackle
- Hardened stainless disc, 70 mm
Confirm diameter and shackle clearance against your hasp. - Branding
- Laser logo · serial numbers
Body and keys, 4 / 6 / 8 digits or your own format. - Packaging
- White box · blister card · printed box · bulk pack
Blister and card artwork confirmed before production.

Fit and compatibility
- Designed for standard self-storage unit doors fitted with a hasp or padlock eye.
- Body diameter and shackle clearance must suit your hasp — send a photo and we confirm with a physical sample.
- On doors with a cylinder cut-out instead of a hasp, use a cylinder lock rather than a padlock.
- For exposed or coastal sites, specify SS304 and confirm the finish in writing.
Fit is a body-diameter question. Send a photo of the hasp with a ruler across it, and we will send a sample disc padlock to check before you commit to a quantity.
Ordering information
Terms for disc padlocks. They are recorded against your account, so a re-order carries the same conditions rather than a new set.
- MOQ
- From 500 pcs
A custom logo, serial numbers and printed packaging are all handled at the standard minimum. The figure is stated on the quotation. - Samples
- From 5 days
Sent so you can check the body diameter against the hasp and the shackle clearance against the door before committing. - Batch production
- Around 30 days after spec and artwork confirmation
Chinese New Year, and the peak season before it, are flagged when you order rather than after the schedule slips. - Delivery terms
- EXW · FOB · CIF · CFR · DDP
Disc padlocks travel well in bulk, so the choice is usually between DDP and FOB rather than between packaging options. - Payment
- T/T · L/C · Credit card
A first disc padlock order normally runs on a deposit, with the balance against the documents or on shipment. - Documentation
- Spec sheet, inspection record, packing list, pre-shipment photos
Records for the body and shackle are issued per model and finish, and sent when you ask for the model you are ordering.
Send the hasp photo, the unit count and the destination country, and the quotation will carry a unit price for that exact configuration.
Options and customization
Disc padlock options that do not change the mechanism — marking, code policy on the combination version, packaging and label.
Branding
Laser logo on the lock body and the keys, plus unit-level serial numbers in 4, 6 or 8 digits.
Code setting
Combination models can be supplied factory-set for a code that is ready on arrival, or user-resettable on site.
Packaging
White box, printed box, blister card or bulk pack. Cards and boxes are produced to your artwork.
Private label
Your brand across body, key and packaging, so the lock arrives as your product rather than ours.

Buyer questions
Which key system should I choose for unit locks?
It depends on how the facility issues locks. Keyed alike suits a defined group of units under one operator. Keyed different gives maximum tenant separation. A master key suits any site where a manager has to open units without the tenant key. Tell us your unit count and we will propose a plan.
Will the lock fit my hasp?
Send a photo of the door and hasp, or the hasp dimensions. We confirm body diameter and shackle clearance with a physical sample before you commit to a quantity.
SS201 or SS304?
SS201 for indoor units and covered corridors. SS304 for exposed outdoor and coastal locations. Both are legitimate — using one grade everywhere is what causes premature replacement. Tell us where the units are.
What actually stops a disc padlock from being cut?
The shackle sits inside the hardened body, and the body turns around it, so a blade cannot reach the shackle in a straight line. On a standard padlock the shackle is the exposed part, which is what makes it the weak point.
Can you quote a unit price for a specific quantity?
Yes. Give us the model, the quantity and the delivery term and the quotation will carry a unit price for that exact configuration, so two options can be compared on the same basis.
