Antimicrobial copper and healthcare projects

Even in the most proactive hospitals, actions such as opening doors, flushing toilets, and turning on faucets can expose patients, healthcare workers, and visitors to antibiotic-resistant superbugs including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecalis (VRE), which can survive on traditional surface materials like or even months.

Cleaning and maintaining stainless steel

With appropriate specification, stainless steel can last the life of a building. However, as with any other material, unsightly surface deposits can accumulate after many years of service. Accidents, vandalism, use of inappropriate cleaning procedures, and installation issues can make surfaces unsightly, cause damage, or even lead to rapid...

Specifying and achieving a level composite steel floor

Composite steel assemblies are an efficient and popular structural option for floor construction. Figure 1 shows a typical assembly, consisting of a steel beam, metal deck, concrete slab, and shear connectors. The composite action between the steel beam and concrete provided by shear connectors creates the composite properties that...

Cold-formed steel design standards

Since the development of the first specifications for cold-formed steel (CFS) building construction in 1946, the American Iron and Steel Institute (AISI) has been working to develop design standards to improve performance and accessibility for designers and structural engineers. These standards have progressed over the years to incorporate the...

More on duplex stainless steel and bridges

In the May 2015 issue of The Construction Specifier, Catherine Houska, CSI, discussed how duplex stainless steels are being specified for numerous structural applications. This complementary web piece looks at a few additional projects from around the world that make use of this versatile material’s attributes.

Specifying Wall Cladding Fasteners

Curtain walls are often the focal point of aesthetic design for a multi-story building. Behind the attractive façade are the pedestrian, yet arguably more important, functional components that ensure safety and reliability—fasteners that transfer loads both imposed and experienced by the assembly to the building’s structural framework.

Duplex Stainless Steel Revolutionizes Structural Design

Architectural and engineering firms are increasingly exploring stainless steel’s possibilities as a structural material as new research, structural codes, and design guides become available. Most designs have used the familiar Types 304L or 316L alloys from the austenitic family of stainless steels, but for all but the lightest sections,...
