Fire Resistance of Composite Beams with Profiled Steel Decking
When a composite beam is constructed using a profiled steel deck, a void is created between the deck and the top flange of the beam. With open trapezoidal steel decks this void is comparatively large while with a 'closed dovetail'&t... FIR003.pdf |

Withdrawal of Welder Qualification Standard NZS 4711
Some changes to the way NZ welders qualify for structural welding will result from the Standards NZ announcement in March 2010 that NZS 4711 is to be withdrawn. With effect from 1 April 2011, new or renewal welder qualifications will not be... WRL1001.pdf |

Galvanic/Dissimilar Metal Corrosion
Galvanic corrosion is the additional corrosion that occurs when dissimilar metals are in contact in the presence of an electrolyte. The corrosion of a metal, the anode, results from the positive current flowing from the anode to the less re... CTG1007.pdf |
