Steel is a fundamental material in construction, but terms like Rebar, round bar, Wire Rod, and coiled rebar can be confusing. This article breaks down the classifications, characteristics, and applications of construction steel in simple terms.

Imai Masa, president of Nippon Steel Corporation, said at a press conference on March 24 that the Trump administration's measures to impose tariffs on steel, aluminum, automobiles and other products may reduce Japan's domestic crude steel output by millions of tons a year, and the total output may fall to less than 80 million tons. 

Round steel pipes, as an essential foundational material in modern industry, are widely used in pipeline transportation, machinery manufacturing, petroleum drilling, and other fields due to their unique structure and versatile properties. 

H-beam is flat, I-beam is slanted. Of course, the difference between the two is not just the difference in the inner side of the flange (also called "leg"). H-beam can be divided into piles, columns and beams according to the width ratio of the flange to the web, while I-beam is basically used as a beam. H-beam has the widest application range in steel structure buildings.

Galvanized steel pipes are welded steel pipes with hot-dip or electro-galvanized layers on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. 

Prestressed concrete is to make the steel bar configured in the tension zone of the component bear a tensile force in advance and generate pretensile stress.

The European Union released the "Steel and Metals Industry Action Plan" to deal with the US tariff shock

Under the goal of carbon neutrality, the Japanese steel industry is actively developing hydrogen reduction ironmaking technology to help achieve the carbon reduction goal of the whole of Japan. In this context, Hideki Murakami introduced that the COURSE50 project was launched in 2008 with the aim of developing hydrogen reduction technology that can be applied in blast furnaces.

What is the difference between Q195, Q215, Q235, Q255 and Q275 in terms of material?

Carbon structural steel is the most used steel, the largest number of often rolled into steel, profiles and profiles, generally do not need to be heat-treated direct use, mainly for general structure and engineering.

I-beams, also known as steel beams, are long strips of steel with an I-shaped cross-section. I-beams are divided into ordinary I-beams and light I-beams. It is a section steel with an I-shaped cross-section.
