Opis produktu
CNC Machined Hot-Dip Galvanized Australian Carbon Steel Round Bars - Industrial Roller Steel Rods
Product Overview

These CNC Machined Hot-Dip Galvanized Australian Carbon Steel Round Bars are precision-engineered solid steel rods designed for heavy-duty industrial roller applications. Manufactured from high-grade carbon steel and finished with a uniform hot-dip galvanized coating, they offer exceptional corrosion resistance, surface smoothness, and dimensional accuracy. Ideal for use in conveyor rollers, track rollers, mining equipment, and agricultural machinery.

Key Specifications
Parameter Details
Material Carbon steel (grades: C45, 1045, A36, or as required)
Surface Finish Hot-dip galvanized (HDG) to AS/NZS 4680 or ASTM A123
Machining Process CNC turning, centerless grinding, cut-to-length, chamfering
Diameter Tolerance ±0.05 mm to ±0.01 mm (depending on CNC precision)
Length Custom from 50 mm to 6000 mm
Surface Roughness (Ra) ≤ 1.6 μm (machined), ≤ 6.3 μm (as-galvanized)
Zinc Coating Thickness 50-100 μm (typical for HDG)
Hardness Customizable via heat treatment (e.g., induction hardening)
Standards AS/NZS 4680, ASTM A123, ISO 1461
Manufacturing Process
  1. Raw Material - High-quality carbon steel round bars sourced from certified mills.
  2. CNC Machining - Precision turning, drilling, threading, or grooving as per customer drawings.
  3. Surface Preparation - Degreasing, pickling, and fluxing to ensure galvanizing adhesion.
  4. Hot-Dip Galvanizing - Immersion in molten zinc bath (approx. 450°C) for full coverage inside and out.
  5. Inspection & Testing - Dimensional check, coating thickness gauge, and visual inspection for uniformity.
  6. Packaging - Rust-proof bundling with plastic caps or wooden crates for export.
Key Features & Benefits
  • CNC Precision - Consistent diameter and straightness for smooth roller assembly and reduced vibration.
  • Superior Corrosion Resistance - Hot-dip galvanizing protects against rust, moisture, chemicals, and salt spray - ideal for outdoor, marine, or mining environments.
  • Smooth Surface - Post-machining and galvanizing ensure low friction for roller rotation and bearing fit.
  • High Strength & Durability - Carbon steel core withstands heavy loads, impact, and wear.
  • Customizable - Length, end finishing (flat/chamfered/threaded), secondary operations (drilling, keyway, etc.) available.
  • Australian Standard Compliant - Meets AS/NZS 4680 requirements for galvanized coatings on steel structures and components.
Applications - Industrial Roller Steel Rods
Industry Typical Use
Material Handling Conveyor roller shafts, belt conveyor idlers, gravity rollers
Mining & Quarrying Heavy-duty track rollers, feeder rollers, impact rollers
Agriculture Roller chains, seed drill rollers, sorting table shafts
Construction Scaffolding caster rollers, concrete mixer drum support rods
Marine & Ports Ship loader rollers, dock conveyor rollers (saltwater resistant)
Automation Linear motion guide shafts, cam followers, support rollers
Hot-Dip Galvanized Australian Carbon Steel Round Bars - CNC Machined Industrial Roller Rods with Customizable Length 0
Quality Control & Testing
  • Dimensional inspection - Digital calipers, micrometers, CMM.
  • Coating thickness - Magnetic thickness gauge (every batch).
  • Adhesion test - Cross-cut or bend test per AS/NZS 4680.
  • Salt spray test - Optional for extreme environment validation (up to 1000 hrs).
  • Surface roughness - Profilometer measurement.
Packaging & Delivery

Packaging:

  • Individual plastic sleeve + foam end caps (for machined surfaces)
  • Steel banded bundles or wooden crates
  • Anti-rust paper and desiccant for long-distance sea freight

Delivery:

  • Lead time: 30-45 days based on quantity & complexity
  • Port: Qingdao / Tianjin / Shanghai
  • Documents: Commercial invoice, packing list, mill certificate, galvanizing test report
