High-Quality 180° Hinge Hardware with Zinc Finish for Cabinet Doors - Bulk Supplier

Sample pricing starts around $2.50 each, drop to roughly $1.80 at 500 units, and at 5,000 you're looking at $1.20 or so per hinge—basically difference between a project and a production run.

Each hinge handles up to 15kg static load, so they're fine for standard cabinet doors but don't push them for heavy-duty workshop doors or anything with constant slamming. The 180° opening is what you want for corner cabinets where every centimeter of access matters.

We've got three material options: carbon steel is the workhorse, aluminum is noticeably lighter but doesn't take as much abuse, and stainless if you're building for outdoor kitchens or humid climates—that one costs more, around 30-40% over carbon steel (check lead time on stainless, it's usually in stock but not always).

ISO 9001 and SGS certified, so you get COAs with every bulk order—usually takes 7 working days for samples once we get your TDS or techncial drawing for the custom finish. The standerd export packaging is decent: corrugated boxes with foam inserts, 25-50 hinges per box depending on your preference.

Minimum is 100 pieces, which is actually pretty manageable if you're just testing a batch of 10-15 cabinets before committing to a full production run. Most buyers doing monthly orders in the 5-10k range go with zinc plating because of that it's cost-effective and passes the corrosion tests we run in-house, though epoxy holds up better if your finishing line sprays after installation.

So anyway, production capacty sits at 500,000 pieces a month—we've never hit that ceiling, but it's there if you need it. The 1-year defects in workmanship, not misuse or overtightening (you'd be surprised how often people crank hinges past their stop).
