Automotive sheet metal limit linkages are precision structural components manufactured through sheet metal stamping and riveting processes. They primarily use cold-rolled steel sheet (SPCC) as the material, and the surface can be treated with color zinc passivation or electro-galvanizing. Common names include door/trunk limit struts, stamped limit arms, galvanized limit brackets, and riveted metal linkages. Widely used in the automotive manufacturing and transportation industries, they are suitable for limiting the opening angle of car doors, hoods, or trunks, providing support and positioning for moving parts of the vehicle body, while also restricting mechanical movement and preventing excessive door opening.
We support customized production based on customer-provided drawings or industry standards.
