Garage Door Security Slide Bolt Lock

Our company, Kunshan Qunju Metal Products Co., Ltd., produces this garage door security slide bolt lock. The model number is QJ-GD1001. The size is 3 inches. This product is more secure than the previous version. We call it a security lock. It has four special features. The first feature is a hardened steel plate in front of the cylinder. A drill cannot go through it. The second feature is a thicker bolt head. The bolt diameter is 10 millimeters. It is very hard to cut. The third feature is two extra screw holes on the lock body. Our R&D team has five people. They spent six months developing this product. The security requirements were high. They looked at safe lock designs for inspiration. The anti-drill plate is made of hardened steel. The hardness reaches HRC55. A normal drill bit cannot drill through it. We did a test. We used a regular hand drill for three minutes. The plate only had a shallow mark. It did not drill through. We recorded a video of this test. You can ask us for it.

Our factory started in October 2017. We have a lot of experience making security locks. We are good at sheet metal and stamping. Many parts of this garage door security slide bolt lock are stamped in one hit on a 200-ton press. High efficiency and accurate size. We have 60 employees. Ten of them work in assembly. Each person can assemble 150 security locks per day. After assembly, they test the key twice. They make sure the cylinder works correctly. How do we ensure on-time delivery? We have stable raw material suppliers. The steel for this security lock is a special grade. We have an agreement with a steel mill in Jiangsu. They reserve 5 tons per month for our security lock. We have a mature management and production team. The production leader makes a production plan two weeks in advance. We have a dedicated order tracker. She updates progress every day.
