Sandwich Panel Screws for Steel Beams
Sandwich panel fixings for steel beam projects
Our sandwich panel to steel beam range is designed for fastening sandwich panels to heavy section steel with a self-drilling solution built for professional installation. The range is centred on hexagon-head screws with a bonded EPDM sealing washer and a larger thread under the head to support secure sealing against the outer sheet.
When choosing within this family, the key questions are the panel thickness, the steel beam thickness and the exposure level of the project. We help you match the right screw length, drilling capacity and material option so the fixing suits both the sandwich panel build-up and the beam you are fastening into.
What is included in our sandwich panel to steel beam range
Standard screws for steel beams
Choose our standard EC range when you are fastening sandwich panels to steel beams from the main heavy-steel drilling range and want a straightforward solution across a wide span of panel thicknesses. This is the core choice for everyday beam-mounted sandwich panel work where drilling capacity, sealing and length all need to line up cleanly.
Variants for thicker steel beams
Move to the selected heavy-duty variants when the beam is thicker than the main EC range and the job calls for higher drilling capacity into heavy steel. These are the right options when standard beam-capacity screws are no longer enough for the substrate you are fastening into.
See technical details for our thicker-steel sandwich panel screws on page 31 in the catalogue.
Stainless options for more exposed projects
Choose our stainless options when the project calls for a more corrosion-resistant fixing while keeping the same sandwich-panel-to-steel-beam installation logic. That makes it easier to stay within one product family while selecting a screw that better matches exposed and more demanding environments.
Bimetal option for demanding steel-beam applications
Choose the bimetal option when you need a stainless outer solution together with drilling performance for demanding steel-beam applications. It is especially useful when panel build-up and substrate demands push you towards the longer and more specialised end of the range.
See the bimetal option for sandwich panel to steel beam fixing on page 31 in the catalogue.
Detailed sandwich panel to steel beam data in our catalogue
In the catalogue below you can compare the full EC range for sandwich panels to heavy section steel. Use it to check panel spans, drilling capacity, washer size, material option and pack format before you decide which screw belongs on the job.
This is the right place to compare the core range for steel beams, the selected variants for thicker heavy steel, and the stainless and bimetal options for more demanding conditions.
Need help choosing the right sandwich panel screw for a steel beam?
If you are balancing panel thickness, steel beam thickness and corrosion demands, we can help you narrow the choice quickly. Our team can point you towards the right EC screw family, the right length and the right material option for the project instead of leaving you to guess from a table alone.
How do I know whether this is the right sandwich panel page for my project?
This is the right page when you are fastening sandwich panels to steel beams or other heavy section steel. If your substrate is light section steel, timber or concrete, you should move to the corresponding dedicated page instead so the drilling capacity and product selection logic match the actual substrate.
What should I compare first when choosing within this range?
Start with the panel thickness and the steel beam thickness. Those two factors usually determine which screw lengths and drilling capacities are relevant. After that, look at the project environment and decide whether a standard, stainless or more specialised option is the better fit.
When should I move to the variants intended for thicker steel beams?
You should move to those variants when the beam thickness goes beyond the main heavy-steel range on the page. In practice, that means you should not try to force a standard option into a thicker substrate than it is intended for. Compare the drilling-capacity range carefully and step up when the beam demands it.
When is a stainless option the better choice for sandwich panels on steel beams?
A stainless option is the better choice when the project calls for a more corrosion-resistant fixing than the standard range. It lets you stay within the same sandwich panel to steel beam family while choosing a material option that is better suited to exposed and more demanding environments.
Why does the larger thread under the head matter on this type of screw?
It matters because this family is designed for sandwich panel installation, where secure sealing against the outer sheet is important. The thread design under the head is part of what makes these screws suitable for the application instead of being just a general steel-to-steel fixing.
