We've been shippng about 200 units a week of these lately, and the 40kg bearing capasity is usually the first thing people ask about — it handles doors up to 1000mm wide with 12mm glass without any sag, which is pretty much standard for commerical showers.

The stainless steel body with nickel plating actually holds up better than some of the chrome finishes we've seen in the past, though it's not suited for outdoor appliction since the coating can pit in salt spray conditions.

Basically, the 90° folding angle means you get a clean open position for the door, and the hinge measures 90mm by 50mm by 55mm, which fits most standard frameless setups we've handled.
Custom colors are available (usually 2-4 weeks lead time), but most buyers go with the standard nickel since it matches most trim hardware, and our company provide online installation guidance if you need it.

OEM and ODM orders are fine, but the MOQ for those is about 50 units or so, and we pack them in hard protective boxes to avoid breakage during shipping.

Also, the nickel plating gives it a decent corrosion resistance for bathroom humidity, though we've seen some issues if the glass thickness is below 8mm — the hinge just doesn't grip as tightly.
We typically start at 100 units for standard orders, but we can negotiate smaller MOQs for first-time buyers or sample requests.
Custom colors add about 10-15 working days to the standard production time, which is usually 25-30 days for a full batch.
Yes, we can provide a material certificate for the stainless steel and a salt spray test report for the nickel plating upon request.
Absolutely, the SVA-309 works with glass thickness from 8 to 12mm and door widths between 800-1000mm, so 10mm thick glass and 900mm width are both well within spec.
Each hinge comes in a hard protective box with foam inserts to keep it secure during transit, and we use double-walled cartons for bulk orders.
