WELDOX is an extra-high structural steel plate that enables you to produce string but light weight load-bearing structures. The costs of materials
and transport can thus be greatly reduced. The plate is very wellsuited for bridges, between 420N/mm2 and 110N/mm2. WELDOX structural plate has been developed to ensure good weldablity together
with the high strength and toughness demanded of a modern structural steel. Due to its low content inclusion, the plate can very readily be bent
Applications Load carrying structures having high demands on low weight.
