Plate Availablity
As steel makes up about 65% of the cost of a welded beam designing the beam to best suit the source material is important for a cost effective design. Our primary plate supplier is NZ Steel, being a local supplier they offer us the best lead times and cost structures but being a smaller producer they they manufacture plate up to 1540mm wide and 5mm to 50mm thick and around 12m long.
Special plate gauges, widths and length outside the normal ranges are available on requests. For material, such as weathering steels, outside this we either source from local merchants or from BlueScope Australia. We hold stock in common gauges, this chart shows our typical stock policy (of course what we have at any time will vary so please contact us).
