Standard part or made-to-measure
When should you choose a standard sheet metal part instead of a custom one?
Short answer: choose a standard part when the shape, dimensions, function and accessories already match your project. Choose custom bending when the support, angle, return, slope, colour, joint or visible alignment needs an exact dimension.
Standard parts are designed for common roofing, wall and facade situations with known dimensions.
The part can be combined with matching accessories instead of improvising each detail on site.
Made-to-measure bending is best when a standard profile would force a poor fit.
Standard or custom: the practical rule
A standard folded sheet metal part is not a lower-quality part. It is simply a profile whose dimensions and accessories are already defined. It is the right choice when your project falls within the existing range.
Choose a standard part if...
- The wall, edge or junction matches an existing width.
- You need a common coping, flashing or finishing trim.
- Matching corners, connectors or end caps are available.
- The site does not require a special angle or return.
Choose custom bending if...
- The finished dimensions are not in the standard range.
- A return, slope, angle or joint must be exact.
- The part is very visible and alignment matters.
- You need a specific material, finish or technical profile.
Decision table before ordering
This table helps you avoid the two common mistakes: ordering a custom part when a standard solution is enough, or forcing a standard part where the site needs a made-to-measure profile.
| Project situation | Best choice | Why |
|---|---|---|
| Flat roof parapet with a width covered by an existing coping series | Standard coping | Fast order, matching corners and connectors, clean finish. |
| Facade or roof edge requiring a common trim or flashing | Standard finishing profile | The shape is already designed for frequent building junctions. |
| Renovation with irregular support or non-standard finished width | Custom bending | The part must follow the real measurement of the site. |
| Architectural detail, special return or visible alignment constraint | Custom bending | The geometry and appearance must be controlled precisely. |
Questions to ask before choosing
- Do I know the finished dimensions? Measure the finished support, including coating, insulation and waterproofing layers.
- Does a standard width already fit? If yes, start with standard folded metal parts.
- Do I need accessories? Corners, connectors, caps and supports often make the standard system more reliable.
- Is the part visible? For a visible facade line, a custom profile can prevent awkward cuts and misalignment.
- Will the part connect to another element? If another material or profile imposes a dimension, custom bending is often safer.
Where to go next
For wall heads and flat roof parapets, start with metal copings. For facade edges, roof junctions and trims, check standard finishing profiles. If your dimensions do not fit the standard range, use the custom sheet metal configurator.
FAQ
Is a standard sheet metal part less professional?
No. A standard part is often the best professional choice when the dimensions and accessories match the job. It reduces uncertainty and ordering time.
Can a standard part be adjusted on site?
Small adjustments are sometimes possible, but a standard part should not be forced into a situation it was not designed for.
When is custom bending the better choice?
Custom bending is better when the exact width, return, angle, material, colour or joint detail is important for fit or appearance.
The right reflex
Start with the standard range when the project is common and compatible. Move to custom bending when the site requires exact geometry.
