More than 35 years of fastening expertise

Because building sheet metal and steel construction have been our home ground since 1987, not just another category in a broad catalogue. That long focus matters in real projects, where the right fastening choice affects compliance, corrosion resistance, drilling performance, installation speed and long-term result. We also support ventilation installers and manufacturing industry customers, which means our knowledge is built around real technical applications rather than standard merchant supply. For customers, that makes Unite Fasteners a stronger partner when fastening is a technical decision with commercial consequences.

The strength of Unite Fasteners is that the three brands solve different parts of the same problem. Unite covers the broad everyday need across screws, bolts, nuts, blind rivets and complementary fastening products. Marutex adds specialist stainless self-drilling performance for exposed and corrosive environments, while Bjarnes System adds specialist clamp systems, tools and technical support for standing seam roofing. Together, that gives customers one partner for both standard fastening and the technically demanding edge cases.

Marutex is one of Unite Fasteners’ clearest technical proof points. The product is described as a homogeneous stainless self-drilling screw for professional use, with RISE type approval, performance linked to C5 conditions and fastening capability in steel up to 15 mm. Unite’s published material also highlights long technical life, use since the mid-1990s and major reference use, including 300,000 Marutex screws in the facade cladding at Friends Arena.

Bjarnes System gives Unite a very unusual level of specialist strength in standing seam roofing. Bjarnes states that it holds 60% of the Swedish market, exports to 15 countries, sells 5.5 million clamps per year and manufactures in Sweden. On top of that, the system includes clamps, banded clamps, Krabban, Clipdriver DF and technical advice, so customers are not buying single parts in isolation — they are buying a complete roofing fastening system with real project support behind it.

Yes. Unite’s own material makes it clear that product choice should be based on the real application, not just a part number. The company’s product selection logic and support cover what is being fixed, the substrate behind it, corrosion demands, clamp length, drilling capacity, colour requirements and installation conditions. That is exactly why Unite is stronger than a supplier that only offers a catalogue and leaves the risk of the selection to the buyer.

Yes. We do not limit ourselves to shelf products when the project calls for something more specific. Customer-unique solutions are part of how we work, and when the exact screw, rivet or fastening detail needed for a project does not already exist in the standard range, we can still help develop a complete solution around the real requirement. That is especially valuable when the challenge involves unusual substrates, demanding environments, visual finish requirements or installation conditions that make a standard product the wrong choice from the start.

Yes — and this is one of our clearest strengths. We can coat almost our full fastening range in virtually any colour, and we know the colour systems used by Scandinavian sheet-profile manufacturers. In many cases, we can deliver colour-matched screws and rivets within five to ten working days, and often even faster thanks to stocked standard colours and efficient handling. For facade and roofing projects, that means you do not have to choose between the right fastening performance and the right visual finish.

We reduce risk by helping customers make better fastening decisions before problems appear on site. That starts with product selection support and continues with broad stockholding, fast deliveries from Uddevalla, structured quality work and practical help when installation questions arise. Our quality and environmental systems are certified to ISO 9001:2015 and ISO 14001:2015, and we also work with ongoing verification of product properties such as drilling capacity, design, surface treatment and material performance. In practice, that helps reduce wrong product choices, delays, finish issues and costly corrections during installation.

Because the most expensive fastening mistakes are often made before installation begins. When we are involved early, we can help match the solution to the substrate, corrosion environment, drilling capacity, clamp length, colour requirements and long-term performance demands before those choices become difficult and expensive to correct. That early support becomes even more valuable in standing seam roofing, where Bjarnes System also adds guidance around dimensioning, calculations, wind load, moving zones and fastening principles for different roof build-ups.
