FX45 vs FX50 ERW Tube Mill Model Comparison
FX45 and FX50 are medium ERW tube mill references for round, square and rectangular welded tube projects used in construction, furniture, greenhouse, machinery and general structural applications.

Model Family Overview
FX45 and FX50 are medium ERW tube mill references for round, square and rectangular welded tube projects used in construction, furniture, greenhouse, machinery and general structural applications. The page separates published technical reference data from project-specific engineering. It is intended to help buyers narrow the model family before a detailed technical discussion.

Application Fit by Model Family
FX45: general structural range
Relevant to mixed production of fencing, guardrail, furniture and general structural tube within the published reference 63 mm round and 50×50 mm square references.
FX50: wider medium-tube range
Extends the published reference family toward 76 mm round, 60×60 mm square and thicker products for buyers with a broader construction or fabrication portfolio.
Mixed commercial orders
The decision should reflect the share of light products versus larger structural sections, not just one maximum inquiry size.
Cutting and downstream work
Heavier products may change flying-saw, end-finishing, run-out and packing requirements even when smaller sizes remain common.
FX45 vs FX50: Medium Tube Mill Selection Guide
This comparison is intended for buyers whose production list sits near the transition between the two published reference model ranges. Review the largest round tube, the largest square tube and the thickest wall as separate engineering conditions.
FX45 reference
- Round: Φ16-63 mm, 0.6-2.5 mm wall
- Square: 12×12-50×50 mm, 0.6-2.0 mm wall
- May suit projects concentrated in the lower portion of this family
FX50 reference
- Round: Φ19-76 mm, 0.7-3.0 mm wall
- Square: 15×15-60×60 mm, 0.7-2.5 mm wall
- Extends the published reference envelope for larger and thicker products
Confirm before choosing
- Actual product mix and production priority
- Material grade and strip tolerance
- Required welding power and cutting method
- Workshop space, voltage and future expansion plan
Medium-Tube Production: Range versus Daily Efficiency
- Define the commercial core: List the products expected to occupy most operating hours before adding occasional upper-range sizes.
- Check forming load: Material grade and wall thickness at each diameter influence stand, roll and drive discussion.
- Match welding demand: HF welding selection should be based on confirmed material and wall combinations, not the model name alone.
- Control dimensional change: Sizing and square-forming requirements should be reviewed for the most frequent structural sections.
- Select the cutting route: Finished length, wall and end condition influence the practical cutting solution.
- Plan downstream handling: Larger FX50-range products may require more run-out space and stronger collection support.
FX45 and FX50 Configuration Trade-Offs
FX45 operating focus
- General structural and fabrication tubes
- Frequent mixed-size production
- Balanced round and hollow-section tooling
- Moderate downstream handling
FX50 operating focus
- Larger medium-range products
- Higher wall and forming demand
- Wider cutting requirements
- More floor space for run-out and handling
How to Prepare an FX45 or FX50 Quotation
Separate regular and peak products
Show which large sizes are regular orders and which only represent occasional market opportunities.
State end requirements
Confirm finished length, burr expectations and any downstream facing, zinc spraying or packing needs.
Provide material details
HR, CR, GI and higher-strength materials can create different forming and welding discussions.
Model Comparison FAQ
What is the main selection difference between FX45 and FX50?
FX50 has a broader published reference round, square and wall reference. FX45 may be better focused when the confirmed commercial range remains below those added boundaries.
Does the highest wall thickness determine the model?
It is important but not sufficient. Diameter, shape, material strength, production mix, welding demand and cutting method must be reviewed together.
Can FX45 be used for structural tube?
FX45 can be discussed for general structural and fabrication products within the engineered range. Send the exact section and wall list for confirmation.
Why is there no separate FX50 model page?
This comparison page preserves the published reference FX50 reference for preliminary selection. The final FX50 configuration should be discussed directly with XFX engineering.
