Product Description

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

Raw Material - High-quality carbon steel round bars sourced from certified mills.
CNC Machining - Precision turning, drilling, threading, or grooving as per customer drawings.
Surface Preparation - Degreasing, pickling, and fluxing to ensure galvanizing adhesion.
Hot-Dip Galvanizing - Immersion in molten zinc bath (approx. 450°C) for full coverage inside and out.
Inspection & Testing - Dimensional check, coating thickness gauge, and visual inspection for uniformity.
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

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.
