- Verify the built radius before releasing production panels.
- Transport and lifting plans must support the curve continuously.
- Stage curved panels in installation order near their final position.
Late planning undermines curved roofing. A vertical roofing curving machine fits only when radius, transport, lifting, and installation sequence agree.
Why should the roof be measured before curving?
Check radius, squareness, high spots, and low spots before releasing panels. A short trial panel beats forcing a long panel onto the wrong substrate.
How should curved panels travel?
Curved panels should travel on supports shaped and spaced for their geometry. The route must account for vehicle height, turning clearance, unloading area, and wind.
What makes a lifting plan credible?
A credible lifting plan identifies weight, pick points, spreaders, tag lines, weather limits, and crew positions. Curved sheets need intermediate support to prevent buckling or twist.
Which published numbers deserve a closer look?
| Published figure | What it describes | Source |
|---|---|---|
| 2 mm | Cover mismatch can make curved-sheet installation very difficult | NZ Metal Roofing COP, 2025 |
| 12 m | Example traditional transport length for curved panels | ArcelorMittal guide, 2019 |
| 4.2 m | Maximum vehicle height cited in the same transport guide | ArcelorMittal guide, 2019 |
Use these figures as comparison inputs, then confirm the current specification and test method with the supplier.
Where can you verify the supplier?
Compare ARTITECT's double-folder overview with its published functions, engineering background, and application articles. Then send real drawings through the profile-review form.
What are shops asking before they commit?
Should curved panels be made from drawings alone?
No. Confirm the built supports before final production whenever the project sequence allows it.
Can curved panels be stacked like straight panels?
Usually not without project-specific support. Curved bundles need cradles that match their shape and enough contact points to prevent distortion.
Where should curved panels be staged?
Place them near their final roof zone in installation order, subject to the structural and lifting plan. The location must preserve clear access and safe edges.
How do you avoid changing the radius during lifting?
Use approved pick points and intermediate support that distributes load along the curve. Keep the panel stable with tag lines and respect wind limits.
What should a curved-roof mock-up include?
Include the curved sheet, straight transition, end closure, gutter or eave, and at least one seam. The mock-up should test effective cover, joint sequence, drainage, appearance, and access.
What should you send for a useful application review?
Send the drawing, material, measured thickness, finish, longest blank, mating details, and the defect you want to remove. Ask for a sample plan with measurable acceptance criteria.
