锁具与门窗五金（锁芯·挂锁·把手·合页）
机械锁采购可拆成锁体、锁芯、锁梁与表面四个维度。永康工厂基本全链自产，价差主要来自锁梁用钢（20Cr渗碳与普通304）、珠针数量、锁体是铜、锌合金还是叠片钢。表面处理（电镀、拉丝、PVD）多外协，它对交期的影响往往大于装配本身。
产业带
浙江永康——挂锁与机械锁主产区；广东中山/温州——建筑门窗五金与不锈钢执手；山东高唐等地补充锁体产能

买家常见问题
What should I verify before importing locks into the EU?
Ask for the EN 12320 (padlock) or EN 1303 (cylinder) test report from a named laboratory, check the keyway is not a public keyway if you want your own brand, and confirm the plating salt-spray hours actually claimed. Only use certificates the factory can produce in full with matching model names.
Are brass or laminated-steel padlocks better for the trade channel?
For retail display, brass-bodied padlocks sell on finish and weight perception; for rental, construction and logistics, laminated steel with a carburised shackle wins on price and parts-replacement. Many buyers carry both and split them by channel rather than picking one.
