Garage Door Slide Latch

Our company, Kunshan Qunju Metal Products Co., Ltd., produces this product. The model number is QJ-GD1001-3. The size is 3 inches. That means the latch length is 3 inches (about 76 millimeters). The working principle is simple. You push the latch out. It goes into a hole on the door frame. You pull the latch back. It unlocks. This product is used for side locking of garage doors. It is also used for yard gates and warehouse doors. We use galvanized steel to make this slide latch. We can also offer powder coating as an option. Our factory covers over 6,000 square meters. We have three plants. This garage door slide latch is made in our second plant. The second plant has four assembly lines. Each line can assemble 500 latches per day. The production steps include stamping, bending, welding, grinding, zinc plating, and assembly. Workers check each step.

How do we control quality? We have a dedicated quality control department. We do two tests on this product. The first is a push-pull force test. We use a force gauge to measure how smoothly the latch moves. The standard is that the force must not exceed 5 Newtons. The second is a salt spray test. We put the latch in a salt spray chamber. After 48 hours, we take it out and check for rust. Our standard is that rust spots must not cover more than 1% of the surface. The latch passes both tests before we ship. We have real customer feedback. A customer in Norway bought our QJ-GD1001-3 latch. He installed it on his own garage door. Norwegian winters are very cold. Minus 20 degrees. He worried that the latch would freeze. After one winter, the latch worked normally. He sent us an email. He was very happy. Now he is our agent. He orders every month.
