[0002] The door sill reinforcement beam is an important part of the car body structure. It is generally distributed along the door sill at the bottom of the car door. It is mostly long and made of high-strength steel and other materials. Its common shapes include U-shaped, grooved, tubular or combined special shapes. Its main function is to enhance the side strength of the car body, effectively absorb and disperse the collision energy during side collision, prevent excessive deformation of the car body, and protect the safety of passengers in the car. At the same time, it is critical to maintain the overall structural integrity of the car body to ensure that the car door can be opened normally after the collision. It is connected to the car body longitudinal beam, B-pillar and other parts. The design and strength of the connection are also very important. During the manufacturing process, its surface will be pre-treated by rust removal and oil removal before painting, including primer, mid-coat, topcoat and varnish, to achieve rust prevention and beautiful effects; The painting of automobile threshold reinforcement beam is an important part of automobile manufacturing or maintenance process.
