Custom Square Steel – Square Steel Bars

Square Steel as a Solid Square Profile

Square steel is one of the classic steel semi-finished products and is characterized by four sides of equal width and a solid square cross-section. Unlike a square tube, a square steel bar has no hollow interior and consists entirely of steel.

The uniform geometry makes square steel a versatile starting material for metalworking, mechanical engineering, workshops and custom constructions. Depending on the application, the material can be used directly as a bar-shaped component or further processed by sawing, drilling, welding and other methods.

Square Steel Made from S235 JR

diconfa currently offers square steel made from S235 JR or 1.0038. The material is also known by the former designation ST37 and is used for numerous classic steel construction, metalworking and general construction applications.

The square steel bar currently offered is supplied as untreated raw material. According to the product information, it can be bent, formed, machined and welded, among other processes. Which type of processing is suitable for the specific project should always be assessed based on the construction and the respective technical requirements.

Untreated Square Steel for Individual Processing

The raw steel version provides a flexible basis for further manufacturing steps. Depending on the project, the square steel can, for example, be drilled, sawn, welded, ground or otherwise processed.

As the current version has no corrosion protection, a suitable subsequent surface treatment may be required for humid environments or outdoor applications. Which treatment is appropriate depends on the intended use.

Choosing the Right Square Steel

Determine the Suitable Cross-Section

For square steel, the cross-section is specified by the side dimension. A square steel bar measuring 20 × 20 mm, for example, has a width of 20 mm on both sides of the cross-section.

The required dimension depends on the construction, load, existing connections and the intended further processing. Various square dimensions are available for the square steel currently offered.

Match the Length to the Component

The required length can be selected to suit the planned construction. This is practical, for example, for frames, brackets, braces or several identical components and can reduce additional cutting work in your own workshop.

Consider the Material and Surface

In addition to the dimensions, the material and surface condition also play an important role. The current range consists of untreated S235 JR. Additional steel grades or versions may be added to the category in the future.

Processing Square Steel

Square steel is often purchased as a semi-finished product and then further processed to suit the required component. The flat outer surfaces can, for example, make marking, clamping, drilling or connecting to other components easier.

According to the product information, the S235 JR square steel currently offered can be bent, formed, machined and welded. The specific processing should be adapted to the material thickness, component geometry and subsequent loads.

Square Steel or Flat Steel?

Square steel and flat steel are solid steel profiles, but differ significantly in shape. With square steel, the width and height of the cross-section are identical. Flat steel, on the other hand, has a rectangular cross-section in which the width is greater than the material thickness.

Square steel is suitable, for example, for bars, frames, supports and construction components with square geometry. For flatter brackets, tabs, reinforcements or flat connecting parts, flat steel may be the more suitable profile shape.

Square Steel or Square Tube?

Square steel and square tube should also be distinguished from one another. Square steel is a solid profile. A square tube, on the other hand, has a hollow interior and a defined wall thickness.

Which design is suitable depends on the respective construction. At diconfa, square tubes will be managed as a separate product group in the future and are not part of this category for solid square steel.

Square Steel within the Rectangular Profiles Category

At diconfa, square steel will form part of the solid rectangular profiles category. This category groups together solid profiles with rectangular or square cross-sections and distinguishes them according to their respective profile shape.

Further solid profile shapes such as flat steel can be found in the parent category Rectangular Profiles. You can also find an overview of round rods, profiles and further metal semi-finished products under Custom Metals.
