Describe the arch at the finished tube centerline
Span, rise and shape belong together
For greenhouse and hoop-house arches, send the finished curve drawing and specify where span and rise are measured. Tube-centerline dimensions are different from the building’s clear internal dimensions.
A single circular arc, an arch with straight legs and a varying-radius profile are different workpieces. Provide the actual shape rather than only a greenhouse width.
Single circular-arc radius check
If the curved section is a single circular arc no higher than a semicircle, use its centerline chord span and rise to estimate the radius. Both inputs must use the selected unit. Straight legs and non-circular roofs need a drawing.
Geometry aid only. This does not confirm machine capacity, tooling or structural suitability. Send the full frame drawing with the inquiry below.
Review the whole arch, including the ends
| Workpiece detail | Selection and acceptance review |
|---|---|
| Tube grade, OD and wall | Match actual material and roller groove. |
| Curved section | Centerline span, rise/radius and the accepted shape. |
| Straight legs / ends | Specify end lengths, joining allowances and any trimming. |
| Tube finish | Identify coating and the accepted surface condition. |
| Finished frame | Review dimensions with the mating connections and assembly. |
Set up for a repeated frame family
- 01
Prepare a representative tube
Use actual length, grade, OD and wall.
- 02
Confirm the rollers
Agree groove fit, adjustment and the supplied forming procedure.
- 03
Form and check the first arch
Use the drawing or accepted checking fixture.
- 04
Repeat and compare
Check curve, ends, surface and assembly fit across the batch.
Rolling or localized tube bending?
Broad continuous curve
The supplied roll-bending route progressively curves the tube for greenhouse arches. Review the complete arc and straight ends as a single workpiece.
Localized elbow or multi-plane part
Use the electric, NC or CNC tube-bending references when the requirement is a distinct bend sequence. Decide from the actual drawing, not a generic pipe-bending name.
Agree the selected rolling machine
| Item | Required model-specific information |
|---|---|
| Capacity | Material, OD, wall and minimum curve conditions. |
| Roll arrangement | Actual rolls, groove sizes, adjustments and included tooling. |
| Drive and control | Power rating, utilities and operator functions. |
| Handling | Support for long tube and removal of the formed arch. |
| Shipment | Current machine dimensions, mass and included accessories. |
The existing greenhouse roller source has no numeric tube-capacity, minimum-radius, motor or output rating. Send WinYing the recurring frame drawings and tube stock so the selected machine and acceptance trial can be specified without borrowing ratings from a localized bender.
Questions to settle before ordering
Is the minimum radius supplied?
No numeric minimum-radius rating is confirmed. Send the actual tube and complete curve.
Can span and rise define every greenhouse arch?
No. They define a circular-arc estimate only under the stated assumptions. Straight legs and other profiles need the drawing.
Are building clear dimensions the tube-centerline dimensions?
No. State the measurement convention and provide the full frame drawing.
How should repeat arches be accepted?
Compare curve, ends, finish and assembly fit with the drawing or agreed checking fixture.
What should the machine quotation include?
Material capacity, roll arrangement, groove sizes, drive/control, support, utilities and shipment data.
Need a Machine for Greenhouse Steel Pipe Bending?
Send tube diameter, wall thickness, material, greenhouse span, arch height or radius and a drawing. We will confirm a suitable machine and roller configuration.
