The Marutex brand
Stainless fastening solutions for harsh environments, heavy steel and long-life construction
Why professionals choose Marutex
Marutex is the stainless fastening brand for professionals who need more than a standard screw for a standard job. It is built for demanding applications where corrosion resistance, drilling performance and long-term reliability all matter at the same time.
Instead of being limited to one narrow use case, Marutex supports fastening across roofing, cladding, steel construction, sandwich panels, ventilation and manufacturing-related sheet metal applications. That makes it a strong starting point when the environment is exposed, the substrate is demanding, or the installation simply has to work first time.
Built for harsh environments
Some fastening decisions are made for easy conditions. Marutex is made for something else. It is developed for environments where heat, cold, vibration, corrosion and high loads are part of everyday service conditions.
That makes Marutex especially relevant in industrial buildings, exposed building envelope projects and steel-related applications where the fastener needs to keep performing over time. When the surrounding environment is demanding, the fastening should not be the weak point in the build-up.
There is a difference between stainless and stainless
Choosing a stainless fastener is not only about choosing something that is “stainless”. Marutex is made from modified martensitic stainless steel, selected to combine strength, hardness and corrosion resistance in a way that suits demanding building applications.
This is one of the reasons Marutex deserves its own position rather than being treated like just another stainless screw. For technical buyers and experienced installers, the alloy and material structure are part of the fastening decision - not background details.
Tested, rated and type approved
Marutex is not positioned around vague claims. It is backed by RISE testing and a type approval, giving professional buyers, consultants and project teams a stronger basis for specification and product selection.
For Marutex martensitic steel, the service life is rated equal to or better than what is stated for AISI 1.4404, classified as C5. That matters when the project requires more confidence in how the fastening solution is expected to perform in corrosive environments over time.
Proven in demanding projects
Marutex is chosen for projects where the fastening solution needs to perform in exposed and demanding environments, not just look good on paper. A strong example is Friends Arena, now Strawberry Arena, where 300,000 Marutex stainless steel construction screws were used for the open facade plates.
That kind of reference matters because it shows Marutex in real use on a large, technically demanding building project. For contractors, facade specialists and project-led teams, it is a clear signal that Marutex is a brand trusted when corrosion resistance, material quality and reliable long-term fastening performance matter from the start.

What is Marutex?
Marutex is our stainless self-drilling construction screw brand for professionals working in environments where corrosion resistance, drilling performance and long technical life matter more than choosing the cheapest screw on the shelf.
The range is designed for demanding applications in roofing, cladding, structural steel, sandwich panels, stainless ventilation systems and other sheet metal constructions where the fastening needs to keep performing over time.
What makes Marutex different from ordinary stainless screws?
Marutex is not just “another stainless screw”. It is made from a modified stainless martensitic steel developed to combine corrosion resistance with the strength and drilling performance needed for demanding construction applications.
For the customer, that means Marutex is built to do more than simply resist rust. It is made to drill efficiently, hold reliably and support faster installation in real project conditions.
Is Marutex approved for C5 environments?
Yes. Marutex is positioned as a C5-approved stainless construction screw for demanding environments where corrosion resistance is a key part of the specification.
That makes Marutex especially relevant in projects exposed to coastal conditions, industrial environments, moisture, condensation, aggressive air and long-term exterior exposure, where a standard screw choice may not be enough.
Is Marutex tested and type approved by RISE?
Yes. Marutex is associated with RISE testing and type approval, which gives specifiers, contractors and buyers stronger support when the fastening choice needs to be backed by more than generic product claims.
For demanding projects, that added confidence matters because the fastening is often a small component with a very large effect on long-term reliability.
Can Marutex drill into thick steel?
Yes. One of the key reasons professionals choose Marutex is that the range includes screws intended for fastening into heavy section steel, with selected variants designed for steel thicknesses up to 15 mm.
That makes Marutex highly relevant in projects where drilling performance, installation speed and dependable fastening into heavier steel members are critical to getting the job done efficiently.
Can Marutex be used for roofing and cladding?
Yes. Marutex includes a broad range of stainless screws for roofing and cladding, including fastening to timber, light section steel and heavy section steel, as well as stitching screws and solutions for visible sheet metal details.
This makes Marutex a strong option for contractors who want a stainless fastening range that covers more than one roof or facade detail within the same project.
Does Marutex include sandwich panel screws?
Yes. The Marutex range includes fastening solutions for sandwich panels to light section steel and sandwich panels to heavy section steel, along with related screws for fittings and detail work around sandwich panel construction.
That makes Marutex useful not only for the main panel fastening, but also for the surrounding project details that often need to be solved with the same level of reliability.
Does Marutex offer screws for stainless ventilation ducts?
Yes. Marutex includes screws developed for stainless ventilation ducts and related duct details, making the brand relevant for ventilation contractors as well as roofing and facade professionals.
This is especially useful when the project needs a fastening solution that works in thin stainless material and supports reliable assembly in ventilation systems where the installation detail matters.
Can Marutex help with airtight ventilation installations?
Yes. The Marutex range includes a ventilation screw intended for stainless ventilation ducts that is described as meeting tightness class D.
For ventilation professionals, that makes Marutex a relevant choice when both the stainless material and the sealing performance of the finished joint are important parts of the installation.
Can I get Marutex in painted colours?
Yes. Marutex can also be supplied in painted finishes, which is useful when the fastening should not only perform technically, but also work visually with the surrounding roofing, cladding or flashing detail.
That gives the customer a more complete stainless fastening solution in projects where both corrosion resistance and visual finish matter.
Has Marutex been used in demanding projects?
Yes. Marutex has been used in major demanding projects, including the facade cladding at Friends Arena in Stockholm, where the project is described as using 300,000 Marutex screws.
That kind of reference matters because it shows that Marutex is not only a catalogue product, but a fastening solution trusted in large-scale real-world construction.
How do I choose the right Marutex screw?
The right Marutex screw depends on more than diameter and length. The selection usually starts with the substrate, the steel thickness, the environmental exposure, whether the detail is part of roofing, cladding, sandwich panels or ventilation, and whether sealing or colour matching is required.
If you are unsure, the fastest route is usually not guessing between references, but talking to us so we can help you narrow the choice down to the Marutex screw that best fits the project.
