BUMAX high-strength, corrosion resistant stainless steel fasteners are used by a broad range of building and infrastructure customers in various highly demanding applications.
Our building and infrastructure offering
The building and infrastructure sector is increasingly turning to high-performance stainless steel to provide low maintenance, durability and full recyclability – to ultimately reduce lifecycle costs and advance sustainable construction. BUMAX stainless steel fasteners provide a highly reliable, cost-effective solution for these demanding applications.
The high strength and exceptional corrosion resistance of BUMAX austenitic and duplex stainless steel grades make even the most challenging construction and infrastructure projects possible. These include non-pre-loaded CE Marked structural bolts in accordance with EN 15048.
BUMAX is one of the only manufacturers experienced in stainless steel pre-loaded structural bolting solutions for slip-critical connections. We also offer Environmental Product Declarations (EPDs) for products in our flagship grades BUMAX® 88 and BUMAX® 109 to help designers achieve transparency on carbon impact.
BUMAX 88 is available in non-preloaded CE marked assemblies, and BUMAX 109 and BUMAX DX 109 is available in pre-loaded assemblies.
