Wholesale Zinc Alloy 180 Degree Shower Hinge - Matte Black Finish Glass Door Hardware

It's a common headache in bathroom installs—getting a glass door that swings both ways without binding or sagging over time, and a 180-degree hinge solves that by letting the door open fully flat against the adjacent panel.

We've had good success shippng these to US and EU buyers, and they pair up with 8-12mm toughened glass without a problem (most frameless enclosures use 10mm, but we've seen 8mm work fine on lighter doors). And the matte black finish holds up better than chrome against hard water spots, so it's a popular pick for modern bathrooms.

The zinc alloy body gets an electroplated surfce that passes a 480-hour salt spray test, which is a step above cheaper hinges that start pitting after six months. The clamp design is what it is—you'll need to tighten the set screws evenly, but once seated, it holds the glass securely at any angle within that 180-degree sweep.

Anyway, for wholsale orders we typically stock 50-100 units, and we handle OEM packing if you need your own branding on teh box or the hinge itself. Lead time runs about 20 days or so form order confirmation, and our company can provide the COA and salt spray test reports for customs clearance—though some importers just need the basic TDS.

One thing you won't get here is a hinge that can support a heavy solid-brass door—this is zinc alloy, so it's best for glass panels up to roughly 12mm thick and a door width of about 800mm max.

The price per hinge drops noticeably past 200 units, though MOQ is 50 pieces for a first order unless we've worked together before on a similar SKU.
