Hexagonal steel is a type of bar with a regular hexagonal cross-section, also known as a hexagonal bar or hexagonal steel bar. It is a commonly used type of steel, mainly used in fields such as building structures, engineering structures, mechanical components, tools, etc.

The cross-sectional size of hexagonal steel is usually based on the nominal length S of the opposite side. Depending on different applications and specifications, the length range of S can vary from a few millimeters to several tens of millimeters. The material of hexagonal steel is usually carbon steel, high carbon steel, stainless steel, etc. Hexagonal steel of different materials has different mechanical properties and uses.

The main uses of hexagonal steel include building structures, engineering structures, mechanical components, tools, etc. In building structures, hexagonal steel can be used to make beams, columns, frames, etc; In engineering structures, it can be used to make bridges, ships, lifting and transportation machinery, etc; In mechanical components, it can be used to make shafts, bolts, nuts, etc; In tools, it can be used to make wrenches, pliers, etc.

The production standards for hexagonal steel are usually controlled according to the national standard "GB 702-2008 Dimensions, Shape, Weight and Allowable Deviation of Hot Rolled Steel Bars" to ensure its dimensional accuracy and mechanical properties. In the market, the price and material of hexagonal steel are related, and the price of hexagonal steel varies depending on different specifications and materials.

In summary, hexagonal steel is an important type of steel with a wide range of applications and market demand. The selection of materials and specifications needs to be based on specific applications to ensure their performance and safety.
