Stainless, plated alloy and coated steel do not share one cleaning routine. We separate them.

Manufacturing faults are separate from change-of-mind returns. Send the order number and clear photographs.
See the service process →Claims have a status
Confirmed, supplier-stated, or not yet verified: the product page should make the difference visible.

Selected, specified, supported
A specialist shop should show its working.
IRONVOW selects restraint hardware from manufacturing partners and publishes the useful differences: inner dimensions, stated material, mass, closure, connections and use limits. We do not present sourced designs as inventions of our own.
When a claim is documented, we identify it. When it is supplier-stated, we say so. When it has not been verified, a blank is more useful than a borrowed number.
Discreet by default
Plain outer packaging with no product imagery. Required carrier and customs information remains accurate.
A registered seller
IRONVOW is operated, fulfilled and supported by 深圳市鼎铂智能科技有限公司 in Shenzhen. Verify the company details.
Claims with a source
Material and dimensions are published for the individual piece. Unknown values are not inferred from a similar item.
Honest ratings
We state exactly what each piece is engineered for — and what it isn't. No piece is rated or intended for suspension of body weight, and we say so.
