Marutex board to steel stud

Stainless board to steel stud screws

What our board to steel stud screws are designed for

Our Marutex board to steel stud screws are designed for fastening roofing or cladding with an intermediate board layer into light section steel. On this page, steel stud is used as the practical site term for that light steel substrate, so the scope stays aligned with the Marutex E-family rather than drifting into general board screws or plasterboard fixings.

This is a very specific build-up screw. The thread-free section helps prevent the outer sheet from being driven up and deformed during installation, while the larger thread under the head helps achieve secure sealing against the outer sheet. In practice, the key selection work is matching the screw to the build-up thickness and the steel thickness you are drilling into.

Detailed board to steel stud screw data in our catalogue

The catalogue below is the best place to compare the three Marutex E screws side by side. It shows the clamp-length bands, the shared drill-capacity span and the product logic for this exact sheet-and-board build-up.

Keep the scope tight to the E-family when the application is roofing or cladding plus intermediate board to light section steel. If the job is really sandwich panel to light section steel, sandwich panel to heavy section steel or a more general board screw application, those belong to neighbouring families and should be selected separately.

Need help matching the screw to your build-up?

If you send us the outer sheet type, the board thickness, the light section steel thickness and the installation environment, we can help you choose between E23, E24 and E25 faster and with less guesswork.

We can also help confirm whether this is truly an E-family board-to-steel-stud application, or whether your project would be better served by a neighbouring Marutex family.

How do I choose between E23, E24 and E25?

Choose between them primarily by clamp-length band. E23 covers 0-18, E24 covers 18-24 and E25 covers 26-38. If your build-up sits near a boundary, it is worth checking the full layer thickness before you commit so the screw matches the application properly.

When is this family the right choice instead of standard board screws or plasterboard screws?

This family is the right choice when you are fastening an outer sheet with an intermediate board layer into light section steel. If the job is really interior plasterboard or another general board-fixing application, this is the wrong family. These screws are built around a sealed sheet-and-board build-up, not ordinary drywall fixing.

What should I check in the steel stud before choosing?

The first check is whether the substrate is actually light section steel and whether the steel thickness fits the shown 1.5-6.0 mm drill-capacity span. If the steel is heavier than that, you should move out of this family instead of trying to force the choice.

Why does clamp length matter so much on this page?

It matters because the E-family is mainly separated by build-up thickness. If the selected screw does not suit the total thickness from the outer sheet through the board layer into the steel, you are no longer working inside the intended product range for that fastening detail.

Can Unite help us confirm whether this is the right Marutex family?

Yes. If you send us the sheet build-up, the board thickness and the light section steel thickness, we can usually confirm quite quickly whether the E-family is right or whether your project belongs in a neighbouring family such as sandwich panel or another fastening category.
