ABOUT LEONHARDT MANUFACTURING

AN ISO-CERTIFIED COMPANY

An ISO 9001:2015 Certified Contract Manufacturing Partner

Founded in 1970, Leonhardt Manufacturing is an ISO-certified contract manufacturer operating from a 95,000 sq. ft. facility headquartered in Hanover, Pennsylvania. We specialize in complex tube fabrication and highly cosmetic tubular components.

Our team helps customers reduce variation, improve manufacturability, and keep production moving through connected
capabilities, tube bending, fabrication, finishing, and assembly, built around clear communication, consistent execution,
and on-time delivery.

Precision tube fabrication for production programs

Excellence in Manufacturing

Quality at Leonhardt is built into how work moves through the shop not inspected in at the end. Our ISO-driven processes
support repeatability from first article through production runs, with documented controls for incoming material, in-process checks, and final verification.

For our customers, that means fewer surprises: stable part-to-part results, clear communication, and a manufacturing partner that responds quickly when priorities change.

Frequently Asked Questions
What does Leonhardt Manufacturing do?
Leonhardt Manufacturing is a full-service contract manufacturing partner specializing in tube and metal fabrication. We produce complex components and assemblies through precision forming, fabrication, finishing, and assembly processes built for consistency, scale, and reliable delivery.
What industries do you serve?

Leonhardt Manufacturing supports manufacturers that depend on precision metal components and repeatable assemblies for production-critical applications. Our work is commonly found in industries where fit, finish, structural integrity, and consistency matter as much as performance, including:

  • Energy & Power Generation (electric, alternative, and infrastructure systems)
  • Engines & Power Systems
  • Data Centers & Communications Infrastructure
  • Defense & Aerospace
  • Transportation & Mobility
  • Automotive & Tier-One Supply Chains
  • Powersports & Recreational Vehicles
  • Construction & Agricultural Equipment
  • Medical Equipment & Devices
  • Hospitality & Commercial Furnishings
  • Consumer Product & Component Manufacturing
What quality standards do you follow?
We operate with documented processes and controlled inspection methods designed to support consistent quality and continuous improvement. If you have specific requirements (PPAP, FAI, etc.), we’ll review them during quoting.
What information do you need to quote a project?
The fastest quotes come from a drawing (PDF) and/or model (STEP), material and finish requirements, annual volume (or run size), target lead time, and any special inspection or packaging needs.
Can you help improve manufacturability or reduce cost?
Often, yes. Small changes—like bend radii, hole-to-bend spacing, weld access, or finish callouts—can improve repeatability and reduce cost. We’ll flag common fabrication design issues during review.
Where are you located?
Leonhardt Manufacturing is based in Hanover, Pennsylvania, supporting customers across the U.S. If your program needs freight coordination or specific routing, we’ll align on logistics during onboarding.
How do we get started?
Send your drawings/models and basic requirements through your preferred contact method or the RFQ form. We’ll review feasibility, clarify any open items, and return next steps for quoting and timeline.
