NZS 3404.1:2009 Looseleaf
Steel structures Standard - Materials, fabrication, and construction
NZS 3404.1 sets out minimum requirements for the selection of materials, corrosion protection systems, and the fabrication, erection and construction of steel structures. It will supersede the relevant provisions in NZS 3404:1997 and will be referenced by NZS 3404.2 to NZS 3404.7 once those parts are complete. This Standard applies to building structures; crane support girders; highway, railway and pedestrian bridges; and composite steel and concrete beams and columns. This Standard is supplied with loose pages with 4 holes punched, suitable for a ring binder with 4 rings.
