FX28 vs FX32 ERW Tube Mill Model Comparison
The FX28 and FX32 family covers small to medium welded tube projects for furniture, greenhouse structures, light construction, agricultural equipment, machinery frames and general steel tube production.
Model Family Overview
The FX28 and FX32 family covers small to medium welded tube projects for furniture, greenhouse structures, light construction, agricultural equipment, machinery frames and general steel tube production. 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
FX28: balanced small-tube production
A practical direction for furniture, greenhouse and light structural products when the confirmed list remains within the published reference 38 mm round and 30×30 mm square references.
FX32: small-to-medium crossover
Provides more published reference range for factories moving toward 50 mm round or 40×40 mm square products and a somewhat heavier structural mix.
Round-to-square planning
The frequency of square and rectangular orders affects sizing design, tooling quantity, setup time and dimensional checks.
Expansion-led investment
A buyer should compare the current order list with the three-year product plan rather than automatically selecting the larger model.
FX28 vs FX32: Compare the Working Range Before Quotation
FX28 and FX32 cover different portions of the small welded-tube market. A useful comparison starts by locating the buyer’s most demanding size-and-wall combinations, then checking square and rectangular requirements separately.
FX28 direction
- Published Reference round range: Φ10-38 mm
- Published Reference round wall: 0.4-1.8 mm
- Published Reference square range: 8×8-30×30 mm
- Suitable for projects concentrated below the FX32 upper range
FX32 direction
- Published Reference round range extends to Φ50 mm
- Published Reference round wall extends to 2.2 mm
- Published Reference square range extends to 40×40 mm
- Provides a wider reference envelope for larger small-tube products
Key engineering checks
- Wall thickness assigned to each tube size
- Material strength and strip condition
- Round-to-square forming plan
- Welding, cutting and roll-tooling requirements
Product-Mix Planning from FX28 to FX32
- Group products by market: Furniture, greenhouse and structural orders can have different surface, wall and dimensional priorities.
- Map strip widths: The combined round and hollow-section list determines the entry range and coil-handling discussion.
- Design the roll passes: The main repeat sizes should guide forming design instead of treating every possible size equally.
- Review welding demand: The highest-demand size-and-wall combinations should be checked separately from the maximum diameter.
- Plan square forming: Confirm whether square tube is occasional or a core product because this changes sizing and roll planning.
- Separate finished products: Run-out and packing flow should keep furniture tube and light structural orders organized without surface damage.
Where the FX28 and FX32 Configurations Diverge
FX28 project emphasis
- Furniture and greenhouse size mix
- Surface-aware handling
- Frequent small-size changeovers
- Small square and rectangular tooling
FX32 project emphasis
- Wider strip and tube range
- More structural products
- Larger square-section planning
- Workshop allowance for future growth
Engineering Inputs for an Expansion Decision
Current sales mix
Identify which sizes produce regular orders and which are only requested occasionally.
Future product boundary
List the largest planned round, square and rectangular products with the wall thickness for each size.
Workshop and changeovers
Provide layout limits and expected roll-change frequency so expansion does not reduce daily operating practicality.
Model Comparison FAQ
Is FX32 automatically better because it covers larger tubes?
No. A larger published reference range is useful only when the sales plan needs it. FX28 may remain the more focused choice for furniture, greenhouse and light structural products.
When does 40×40 mm square tube affect the decision?
If 40×40 mm is a confirmed core product, FX32 should be reviewed because the published reference FX28 square reference ends at 30×30 mm. Final wall and tooling compatibility still require engineering confirmation.
Should future products be included in the quotation?
Yes. Separate confirmed launch products from future products so XFX can review expansion room without treating every possibility as a first-stage requirement.
Can both models make round and square tube?
Both families can be discussed for round and hollow sections within the engineered range. The final roll design and forming route depend on the complete tube list.
