In modern industrial systems, carbon steel plates are among the most widely used structural materials. Based on different rolling processes, carbon steel plates are divided into two main types: cold-rolled plates and hot-rolled plates.

A Hollow Section, commonly referred to as Hollow Structural Section (HSS), is a type of structural steel product characterized by a closed, hollow cross-section. Hollow sections are widely used in construction, infrastructure, mechanical engineering, and industrial fabrication due to their excellent strength-to-weight ratio, uniform load distribution, and clean appearance.

H-shaped steel is a type of hot-rolled steel with a cross-section shaped like the English letter "H," belonging to the category of economical and efficient structural steel.

Galvanized angle steel bar is one of the most widely used structural steel products in construction, infrastructure, and industrial projects. By applying a zinc coating to the surface of carbon steel angle bars, galvanization significantly improves corrosion resistance and extends service life, especially in outdoor and aggressive environments.

The thickness of a stainless steel flange is not only the physical foundation supporting the piping system, but also the first line of defense against media leakage.

In the development of the construction industry, H-beams, as a new type of economical building steel, have become a core material for modern steel structure buildings due to their unique cross-sectional shape and superior mechanical properties.
