Agricultural Machinery Components
Custom Agricultural Machinery Components and Welded Steel Assemblies for OEM Implements
We supply build-to-print agricultural machinery components and welded steel assemblies for agricultural equipment OEMs and implement manufacturers. Operating from an integrated production facility utilizing high-tonnage stamping presses, robotic MIG/TIG welding cells, and CNC machining centers, we convert engineering blueprints into durable, field-ready metal parts. Every component is produced strictly to OEM drawings, backed by complete material traceability and standardized mechanical testing.

Materials and Fabrication Options
Carbon and Structural Steels: ASTM A36, Q355B, Q355D, S275JR, and S355JR for general structural frames.
High-Strength and Wear-Resistant Steels: Hardox 450 and Hardox 500 wear plates and high-yield structural steels for soil-engaging or high-friction contact zones.
Alloy Steels: 20CrMnTi and 40Cr grades for components requiring case-hardening or heat treatment.
Surface Finishes and Corrosion Protection:
Powder Coating: Heavy-duty industrial powder coating over phosphate-pretreated surfaces, resistant to agricultural chemicals, UV exposure, and mechanical scratching.
Hot-Dip Galvanizing: Compliance with ASTM A123 and ISO 1461 for fertilizer spreaders and manure handling equipment.
Electro-Galvanizing and Zinc Plating: Clear or yellow chromate conversion coatings for small fasteners and brackets.
Application and Working Environment
Soil-Engaging Tillage Equipment
Disc harrows, moldboard plows, field cultivators, and rotary tillers operating in abrasive mineral soils.
Harvesting Machinery
Combine harvesters, forage harvesters, and balers operating under high vibrational stress and dynamic loads.
Seeding and Fertilization Systems
Air seeders, grain drills, and fertilizer spreaders exposed to corrosive chemical fertilizers and moisture.
Tractor Attachments and Utility Implements
Front-end loaders, backhoes, mowers, and transport utility trailers.
Manufacturing and Quality Control
Raw Material Verification: Mill Test Reports verified against physical incoming sheet and plate inspections, including thickness and tensile verification.
Precision Blanking and Forming: CNC laser cutting, high-definition plasma cutting, and CNC press brake bending up to 500 tons for tight angular consistency.
Weld Quality Assurance: 100 percent visual inspection by certified welding inspectors, with optional Magnetic Particle Testing or Ultrasonic Testing for critical structural joints.
Dimensional Audit: CMM coordinate measuring machines and dedicated go/no-go gauges used to verify complex hole patterns and sub-assembly dimensions.
Surface Prep and Coating Audit: Cross-hatch adhesion testing, dry film thickness measurements, and salt spray corrosion resistance monitoring.
