Stainless Steel Garage Door Hinges

Our company, Kunshan Qunju Metal Products Co., Ltd., produces these stainless steel garage door hinges. The model number is QJ-GD1002. This hinge is a center hinge. It is installed between door panels. Sectional garage doors need hinges to connect each panel. Our hinge lets the panels fold. When the door goes up, the hinge bends. When the door comes down, the hinge straightens. We use stainless steel to make these product. The stainless steel grade is 304. 304 stainless steel does not rust. It resists corrosion very well. We can also make them with 201 stainless steel. That is cheaper. But we recommend 304 because garage doors may get rain. We did a salt spray test. The 304 stainless steel hinges sat in the salt spray chamber for 96 hours. There were no rust spots on the surface.

Our hinges are made with precision stamping. One stamping step forms the whole hinge. The stamping force is 160 tons. The hole positions are very accurate. The hole diameter is 8 millimeters. The error is plus or minus 0.1 millimeters. This precision means bolts go through easily. They do not get stuck. We do a test assembly on each hinge. The worker puts a bolt through the hole. If it feels tight, the hinge is set aside and re-punched. We have a professional R&D team. Five people focus on product development and improvement. They recently improved the hinge design. They added two oil grooves. You can use a syringe to push lubricant into the grooves. This makes these stainless steel garage door hinges turn more smoothly. It also makes less noise. This design has been filed for a utility model patent. Many customers really like it.

These product are built to last. The 304 stainless steel is the best choice for outdoor use. Rain, snow, and humidity will not hurt them. The precision stamping means the two hinge halves fit together perfectly. The pin goes in smoothly. The added oil grooves are a real plus. You can add oil without taking the hinge apart. The hinge will stay quiet for years. We make other hinge types too. But this center hinge is our most popular. Our factory has over 6,000 square meters. We have 60 workers.
