World produced around 1870 million metric tonnes of steel in 2019. China is the leader producing more than 50% of the steel. In 2019, world steel production increased by around 3.4% compared to in 2018. In this article, we will compare data of top 10 steel producing countries.
Continue reading Top 10 Steel Producing CountriesIn this post, we compare top seven steel companies across various available parameters. We will be comparing data only for publicly listed companies which include Tata Steel, JSW Steel, SAIL, NMDC, Jindal Steel, Jindal Saw, Jindal Stainless and APL Apollo. Comparison will be done on basis of financial data, credit ratings and digital/social value.

Different properties of steel can be majorly classified under three types, i.e. Physical, Chemical and Mechanical. Here we will discuss the controlling factors influencing the steel properties.
Continue reading Controlling Factors of Steel PropertiesTubular Structures are one of most economical structures. Tube sections have small self weights which lowers their cost and increases their efficiency. In normal conversation, tubes are often referred as pipes too. They come in various shapes, round and rectangular being the most common.
Continue reading Tubes and Pipes – Importance of Tubular StructuresCold formed sections of steel are new development when compared to hot rolled sections. Light gauge sections are formed in mass production by rolling the material in cold condition. At small scale, they can also be economically formed by bending the steel sheets or strips in press brakes.
Continue reading Light Gauge Sections – Cold Formed SteelFor designing a steel structure, first the dimensional requirement of the structure should be defined. After this, possible combinations of loads acting on the structure must be defined. Loads provide an important understanding on the design of structure and type of steel section to use.
Continue reading Loads and Design of Steel StructuresHot rolled steel sections are the most widely used sections and includes largest category of shapes available. Sections are chosen according to the structural design requirements and availability.

Roof trusses are common in buildings of Steel with roof sheets. Steel trusses prove economical for span greater than 12 meter.

Piles are used when the soil is loose and will not be able to withstand the load coming from the structure. Steel Piles are often used because of their high bearing capacity and ability to withstand stresses. Steel Piles are used as the load bearing piles in three different forms: (1) H-Beam Piles, (2) Box Piles and (3) Tube Piles.
