Gate Panel: Thickness 0.8-1.6 mm, Weight 3.5-8.2 kg

Component Specifications

Definition

The gate panel is a stamped or formed metal component that serves as the primary structural element of a vehicle tailgate assembly. It provides the foundational framework for attaching hinges, latches, handles, and other hardware while maintaining dimensional stability under load. In modern vehicles, it often integrates with safety systems and electronic components.

Working Principle

The gate panel functions as a load-bearing structure that distributes forces from cargo weight, opening/closing mechanisms, and road vibrations. It maintains geometric integrity through engineered stiffness while providing attachment points for functional components. Its design follows automotive body-in-white principles for strength-to-weight optimization.

Materials

High-strength steel (HSS) grades 340-590 MPa, aluminum alloys (5000/6000 series), or composite materials. Surface treatments include electrocoating, powder coating, or galvanization for corrosion resistance.
