We’ve been supplying these 180° hinges for casement windows long enough to know the cheap steel alternatives just don’t hold up in coastal environments — the alumnum alloy here actually resists corrosion without needing a thick coating that flakes off after a season or two.
Powder coating is standerd, but what it does is bond to the suface better than liquid paint, so you’re looking at roughly 60–80 microns of consistent finish that handles UV and moisture (usually we recommend RAL colors, but we can match your custom swatch if you send it with PO).
Most buyers go with the JX22D for residential projects where you need that full 180° opening for egress or cleaning access, but it’s not suited for commerical curtain wall systems with heavy triple-glazed units — the alloy is strong, but we’d spec a steel hinge for those loads.
CE and ISO9001 are, and we include COAs with the shipment; the GMC certification is actually a factory audit that confirms we’re not just stamping parts from a third-party foundry, which matters when you’re sourcing from Guangdong.
Lead time is typically 20 days or so for standard powder coat colors, but custom colors add about a week — MOQ is 5,000 units, and we usually have stock on the natural silver finish if you need a smaller test run first.
Our MOQ for the JX22D is typically 500 pieces per color and finish, but we can discuss smaller trial orders depending on your needs.
Lead time is usually 25–30 days after order confirmation and deposit, though it can vary based on quantity and customization.
Yes, we can supply CE, ISO9001, and GMC certificates along with the shipment upon request.
Absolutely, we offer customized color options and can match your RAL code for the powder coating finish.
They come in sturdy cartons with foam inserts, then palletized and wrapped for sea freight to prevent damage during transit.
