S355J2+N is an unalloyed and low carbon steel grade that is offered in hot rolled as well as cold drawn conditions. The average yield for this grade of steel is 355 N/mm². Thus, the name given to this material is S355 and here “S” represents the structure of the steel. The main purpose for which this material is produced is that it reduces the slipping in concrete. Also, it can limit cracks in the concrete by stretching the bars.

S355J2+N Round Bars: The Ultimate Guide for UAE Engineers & Buyers 

Choosing the appropriate structural steel is not merely a decision in the UAE's challenging industrial and construction landscape; it is essential to the project's success, longevity, and safety. From the sturdy machinery in Abu Dhabi's industrial zones to the skeletons of Dubai's skyscrapers, S355J2+N Round Bars are a standout option for high-stress applications. Unlike any other source, this comprehensive guide offers deeper insights and more useful information on S355J2+N Round Bars, covering everything engineers, procurement managers, and fabricators working in the United Arab Emirates need to know. 

What Exactly Are S355J2+N Round Bars? Understanding the Grade 

The European EN 10025-2 standard defines the structural steel grade S355J2+N as non-alloy quality. Its qualities are revealed by the code in its name: 

• S355: Denotes a minimum yield strength at thicknesses < 16 mm of 355 Megapascals (MPa). Before it starts to irreversibly distort, this is the most important indicator of its load-bearing capacity. 

• J2: Specifies the impact toughness (27 Joules) at -20°C. The "J2" grade means it is suitable for applications where low temperatures are a factor, a crucial property for materials used in offshore environments, chilled storage facilities, or even desert nights where temperatures can drop significantly. 

• +N: Signifies that the material is normalized rolled. This controlled rolling process refines the grain structure of the steel, enhancing its toughness, mechanical properties, and overall consistency throughout the cross-section of the round bar. 

Key Properties: Why S355J2+N is a Top Choice in the UAE 

1. Mechanical Properties (The Source of its Strength)

The following table outlines the guaranteed mechanical properties as per EN 10025-2: 

2. Chemical Composition (The Recipe for Performance)

The carefully balanced chemical composition is what creates these mechanical properties. 

Top Applications of S355J2+N Round Bars in the UAE and GCC 

Because of its adaptability, this steel grade is essential to many companies in the area: 

• Construction & Infrastructure: Infrastructure & Construction: Main and secondary structural elements (beams, columns, bracings) for stadiums, high-rise structures, bridges, and airports (such as Dubai World Central). 

• Heavy Equipment & Machinery: Heavy machinery and equipment include lifting parts for cranes and excavators, crankshafts, axles, and hydraulic cylinders utilized in large-scale projects like the Khalifa Port in Abu Dhabi and the Dubai Creek Tower. 

• Oil, Gas, and Energy: Platforms, support structures, and processing equipment are manufactured for onshore and offshore facilities in the oil, gas, and energy sectors. One of its main advantages is its resistance to low temperatures. 

• Marine and Shipbuilding: Components for Abu Dhabi Ship Building (ADSB) and Dubai Drydocks shipbuilding and maintenance yards, where durability and resistance to corrosion are critical. 

• Fabrication and Workshop Use: A material of choice for UAE metal fabricators that make custom frames, supports, and parts for a variety of industrial customers. 

Available Sizes and Specifications for UAE Stockists 

To satisfy local demand, reputable suppliers in the United Arab Emirates, such as those located in the Musaffah Industrial Area or Jebel Ali Free Zone (JAFZA), usually keep a large assortment of sizes in stock. 

• Common Diameters: 10 mm, 20 mm, 25 mm, 30 mm, 40 mm, 50 mm, 60 mm, 80 mm, 100 mm, 120 mm, 150 mm, and 200 mm all fit this description. 

• Standard Lengths: The most popular lengths are 6 and 12 meters, but custom cut lengths are frequently offered. 

• Certification: A Mill Test Certificate (MTC or EN 10204 3.1/3.2) should always be insisted upon. Since it ensures traceability and the chemical and physical qualities of the provided substance, this is non-negotiable in the United Arab Emirates. 

S355J2+N vs. S355JR: Choosing the Right Grade for Your Project 

The distinction between S355J2+N and the more popular S355JR is a frequent source of misunderstanding. 

• S355J2+N: Tested for impact at -20°C. improved internal structure by normalized rolling. superior resilience. 

• S355JR: Impact was evaluated at room temperature, or +20°C. not accepted as usual. Sufficient for general applications that don't require low temperatures. 

For the UAE: S355J2+N is the safer, higher-performance option for essential structures, outdoor applications subject to temperature fluctuations, and any project where increased safety and durability are a top concern, even though S355JR is frequently adequate for many interior or general structural applications. 

FAQ: S355J2+N Round Bars in the UAE 

Where can I buy certified S355J2+N Round Bars in Dubai, Abu Dhabi, or Sharjah?  

Seek out reputable suppliers and stockists who are physically located in important industrial areas (JAFZA, DIC, Mussafah). They ought to offer processing services including drilling, threading, and cutting in addition to comprehensive material certification (MTC). 

Is S355J2+N round bar weldable?  

Yes, because of its well-regulated carbon content, it offers outstanding weldability. It is possible to employ standard welding techniques (SMAW, GMAW, and GTAW). It is advised to adhere to a certified Welding Procedure Specification (WPS) for sensitive applications. 

How does the desert climate of the UAE affect S355J2+N steel?  

Despite having a higher resistance to atmospheric corrosion than carbon steel, S355J2+N will rust if exposed to the severe UAE environment, which includes heat, humidity, and salty air. For long-term durability, suitable protective coatings (painting, galvanizing, and metallization) are necessary for outdoor use. 

What is the price per kg or per ton for S355J2+N Round Bars?  

Pricing fluctuates and is influenced by supplier margins, diameter, quantity, and steel pricing globally. It is always best to request a direct quotation from suppliers for your specific project requirements. Usually, quotes are given in either USD or AED per metric ton.
