INDUSTRY COMPONENT

Strike Plate

A metal plate that receives the latch bolt in a locking system to secure doors or panels.

Component Specifications

Definition
A strike plate is a critical component in mechanical locking systems, typically mounted on the door frame or jamb to receive and secure the latch bolt from the lock mechanism. It provides a reinforced interface that distributes mechanical stress during latching operations, prevents door misalignment, and enhances security by resisting forced entry attempts through its design and material strength.
Working Principle
The strike plate operates by providing a precisely aligned opening (strike) that guides and captures the latch bolt when the door is closed. When the latch bolt engages with the strike plate, it creates a secure mechanical connection that prevents unauthorized opening. The plate's design includes beveled edges to facilitate smooth bolt entry and reinforced mounting points to withstand operational forces.
Materials
Commonly manufactured from cold-rolled steel (AISI 1018/1020), stainless steel (304/316 grades), or zinc-plated steel for corrosion resistance. High-security applications may use hardened steel or alloys with tensile strength exceeding 500 MPa.
Technical Parameters
  • Finish Zinc plating, powder coating, or polished stainless
  • Hardness HRB 70-85 for standard plates
  • Thickness 2-4 mm
  • Mounting Hole Pattern Standard 3-hole (82mm centers)
  • Strike Opening Dimensions Varies by latch type (typically 19x38mm for cylindrical locks)
Standards
ISO 9001, DIN 18251, ANSI/BHMA A156.2
