Rising use of lean duplex
Over the past five to ten years, the amount of lean duplex specified in bridge and general construction projects has increased significantly. Sverdup Steel stocks a wide range of grades for this industry including:
- EN 1.4482 – UNS S32001 – LD24 – PRE24
- EN 1.4162 – UNS S32101 – LDX2101 – PRE26
- EN 1.4362 – UNS S32304 – EDX2304 – PRE28 (NORSOK)
The increasing interest in lean duplex is largely the result of new thinking to explore innovative ways to be more cost-efficient, sustainable, and competitive. Today it is clear that lean duplex is becoming the preferred material of choice for applications such as storage tanks, pressure vessels, heat exchangers, bridges, railings, feeding systems, water treatment systems, pipe support and fire- and blast walls on offshore platforms.
As a solution provider, Sverdrup Steel has worked closely with its customers for many years to specify and utilise the benefits of lean duplex. Its team has learned that it needs to offer a wide range of product forms and have excellent stock availability. Today, its standardised stock program includes hot rolled angles and hollow structural sections in lean duplex, as well as plates. It can also offer flat bars, press-brake, and welded profiles with short delivery times.
The company expects interest in the use of lean duplexes will only continue to increase in the years ahead, with a higher focus on more sustainable and durable solutions.
