Unite sheet to steel beam screws
Sheet to steel beam screws for roofing and cladding
Choose the right sheet to steel beam screw
Our sheet to steel beam screws are intended for fastening roofing and cladding to heavy section steel, where the substrate is thicker, the drill point has to match the beam, and the wrong choice can slow down installation or create an unnecessary specification problem.
In this range, you can compare both standard screws and Marutex stainless options, as well as a dedicated flange-head version for insulated, load-bearing roofing. The key is to match the screw to the steel thickness, clamp length, corrosion demand and the actual roof or wall build-up.
Options in our sheet to steel beam screw range
Standard screws for heavy section steel
Choose our standard sheet to steel beam screws when you are fastening roofing or cladding to heavy section steel in normal corrosion environments and want the familiar combination of hexagon head and bonded EPDM sealing washer. This is the main starting point for steel-frame roof and wall applications, and the right option is mainly decided by beam thickness and required clamp length.
Marutex stainless screws for steel beams
Choose our Marutex stainless sheet to steel beam screws when corrosion resistance is more demanding or the project calls for stainless fastening on heavy steel sections. This part of the range lets you compare both hexagon-head and pan-head variants while still choosing by the same practical factors: steel thickness, clamp length and build-up.
See sizes and technical data for our Marutex heavy-section-steel screws on page 25 in the catalogue.
Flange-head screws for insulated roofing
Use our flange-head sheet to steel beam screw when you are fastening insulated, load-bearing roofing sheet to a steel beam and want the dedicated 14 mm flange-head solution shown in this family. It is a more specific choice than the standard washer-based screws and belongs in roof build-ups where that flange-head format is the better match for the assembly detail.
See the flange-head option for insulated load-bearing roofing on page 25 in the catalogue.
Detailed sheet to steel beam screw data in our catalogue
Below, you can compare drill capacity, clamp length, corrosion class and head format across our sheet to steel beam range. That makes it much easier to separate standard heavy-section-steel screws from Marutex stainless options and to see when the flange-head version is the better fit.

Need help choosing the right screw for a steel beam application?
We help contractors, roofing companies and technical buyers compare beam thickness, corrosion demand, clamp length and roof build-up before the wrong screw ends up on site. If you are weighing standard carbon steel against Marutex stainless, or deciding whether the flange-head version is the better fit for an insulated roof, we can help you narrow the choice quickly.
How do I choose between standard sheet to steel beam screws and Marutex stainless screws?
Start with the corrosion requirement. Standard sheet to steel beam screws are the natural starting point for more ordinary conditions, while Marutex stainless screws are the stronger fit when the project needs a stainless solution for more demanding environments. After that, narrow the choice by beam thickness, clamp length and head format.
Do I need to match the screw to the steel beam thickness?
Yes. Beam thickness is one of the first checks, because the screws in this family are specified for different drilling ranges. Choosing by length alone is not enough - the drill point has to match the steel you are fastening into, otherwise installation becomes slower or the screw is simply the wrong option for the substrate.
When is the flange-head version the better choice?
Use the flange-head version when you are fastening insulated, load-bearing roofing sheet to a steel beam and the build-up is intended for that format. For more general roofing and cladding applications to heavy section steel, the washer-based screws are usually the first range to compare.
Do I always need a sealing washer on this type of screw?
For the standard sheet to steel beam range on this page, bonded EPDM sealing washers are part of the normal product format. The clear exception is the dedicated flange-head version for insulated, load-bearing roofing, so it is important to choose the format that matches the actual assembly detail instead of treating them as interchangeable.
Why does clamp length matter on sheet to steel beam screws?
Because the screw has to work through the outer sheet and the full build-up before it seats correctly into the steel beam. If clamp length is wrong, installation becomes awkward and the fixing may be poorly matched to the assembly. Check clamp length together with beam thickness, not as a separate afterthought.
