Unite, Marutex & Bjarnes System
Specialist brands for steel, sheet metal and standing seam roofing
Choose Unite when you need breadth. Our Unite range covers screws, bolts, nuts, blind rivets and complementary fastening products for steel construction, sheet metal work, HVAC installation and manufacturing. It is the right starting point when you want a broad fastening range, colour-matched options and practical guidance across many installation types.
Choose Marutex when corrosion resistance and drilling performance are critical. Marutex is our stainless self-drilling specialist for exposed environments, with RISE-tested and type-approved positioning for corrosivity class C5 and drilling capacity for steel thicknesses up to 15 mm. It is the right brand for demanding sheet-metal applications where long service life and confidence matter.
Choose Bjarnes System when the project is built around standing seam metal roofing. Bjarnes System brings specialist clips, Krabban solutions for insulated roofs, Clipdriver tools and technical advice for clip choice, wind-load calculations and fastening plans. It is the most system-driven brand in the group for professional standing seam installation.
Need help choosing the right brand?
Some projects need a broad fastener range. Others need stainless self-drilling screws for harsh environments or a specialist clip system for standing seam roofs. We help you match the right brand to the substrate, corrosion class, roof build-up and installation method.
Tell us what you are building, and we will point you to the right range faster.
What is the difference between Unite, Marutex and Bjarnes System?
Unite is the broad main range, Marutex is the stainless specialist, and Bjarnes System is the standing seam specialist. Choose Unite when you need a wide fastening assortment across several applications, Marutex when exposed environments and stainless self-drilling performance matter, and Bjarnes System when the project requires clips, Krabban or tools for standing seam roofing.
When should I choose Marutex instead of the wider Unite range?
Choose Marutex when corrosion resistance, stainless material and demanding steel-to-steel drilling are key requirements. Marutex is positioned for harsh environments, is presented as tested and type approved for C5, and is highlighted for drilling in steel thicknesses up to 15 mm. That makes it the sharper choice when the environment is more demanding than a standard fastening job.
When is Bjarnes System the better choice?
Bjarnes System is the better choice for standing seam metal roofs. The brand is built around clips, fasteners, Krabban for insulated roofs, Clipdriver installation tools and project-specific technical advice. It is not just a product label, but a more complete installation system for this roofing method.
Can Unite help us choose the right brand for our project?
Yes. Unite positions itself around knowledge, support and helping customers find the right fastening solution, and Bjarnes System also explicitly offers technical advice tied to fastening plans and wind-load calculations. That makes it natural to invite the visitor to contact you before they choose a brand or system.
Do the brands overlap?
There is some overlap, but the roles are still different. Unite covers the broad fastening landscape, Marutex sits inside the more corrosion-critical stainless segment, and Bjarnes System focuses on standing seam clips and related installation solutions. That overlap is actually useful, because it lets you guide the customer toward the most suitable level of specialisation.
