Out of Jiangmen, Guangdong, these are the hinges we've been shiping for custom door jobs — the DDSS020L in 80x80x2.5mm with that matte black nickel plating that doesn't chip as fast as some cheaper electroplated finishes.
You're looking at a 180-degree swing, five knuckles for stability, and you can order them with either square or round corners depending on your frame prep, and the pin can be removable or non-removable — we usually see non-removable for fire-rated doors since it's one less thing to worry about in a test.
It works on wooden doors, metal doors, and fire-rated doors, but honestly, for the fire-rated ones you'll want to check your local code because we don't have every certification on file for every batch (usually CE and UL are on the COA, but confirm lead time if you need strict paperwork).
The stainless steel base is either 201, 304, or 316 — most buyers go with 304 for interior work since it's a good balance of corrosion resistnce and cost, and 316 is overkill unless you're near saltwater or chemicals.
Custom finishes are where it gets interesting: we've done silver, black, gold, antique brass, and antique copper in PVD or physical vapor deposition (which basically holds up better than paint for outdoor exposure), and the MOQ on custom colors is 500 units or so — otherwise it's stock black or silver in white box or color box packging.
Yes, we can do 201, 304, or 316 stainless steel. 316 is marine grade and costs a bit more, so lead time usually stays the same but price goes up. Just specify when you order.
For OEM orders with your logo, the MOQ is typically 500 pieces. We can work smaller quantities for sample orders first.
Yes, this hinge is CE and UL certified. We'll include copies of the certificates with your order—just request them in your PO.
Absolutely, we offer both square and round corners, and you can choose removable or non-removable pins. Custom orders usually take 25-30 days after sample approval.
We pack in either white or color boxes, then cartons for export. Color boxes are fine, but they might add a small cost per unit. Let us know your preference.
