When a buyer's customer needs to swing open a machine guard fully for maintenance or access a control cabinet that gets opened and closed dozens of times a shift, this zinc alloy hinge handles that daily abuse without slop or failure—it's built for that specific kind of repetitive indutrial use.
180-degree rotation is what most buyers ask for first, and the 30mm hole spacing lines up perfectly with 3030 series aluminum profiles, so installation is pretty much just bolt it on and go, usually within 20 days or so form order.
The black finish isn't just for looks; it holds up better than raw zinc in environments with fluids or humidity, though it's not suited for outdoor exposure where you'd want stainlss, and we typically recommend ordering 1000PCS per pack for bulk pricing to kick in.
500PCS packs exist if you're prototyping, but most buyers go with the 2000PCS option for, and we usually have stock on these hinges but confirm lead time if you need them in under two weeks.
SGS certified means the load capacity and material consistency are tested, so you're not guessing if a batch will hold up—one thing buyers don't think to ask is that the hinge pin is a separate piece that can wear, so we include a spare per 50 units or so in bulk packs.
The 500PCS pack is one of the standard package options, so you can order just that single pack if needed—no minimum above that. For larger runs, we also have 1000PCS and 2000PCS packs available.
Yes, this hinge is SGS certified, and we can provide the certification documents upon request. Just let us know when you place the order, and we'll include them with the shipment.
No, this hinge is specifically designed for 3030 series profiles with a 30mm x 30mm hole spacing. It won't fit properly on a 4040 profile due to the different dimensions.
For a 2000PCS order, we usually ship within 7 to 10 business days after payment confirmation. If you need it faster, let us know and we can check stock availability.
Keep them in the original packaging or a dry, clean area to avoid any surface damage. The black finish is durable, but stacking heavy items on top could cause scratches, so store them flat and separated if possible.
