The advantages of cold-rolled open profiles over hot-rolled beams

Exact dimensions and straightness

Cold-formed profiles are made from coils that have tight thickness tolerances. Cold forming is a continuous process that results in tolerances suitable for applications requiring technical precision. Tolerances in all steps of the process are monitored regularly. Steel profiles produced through cold-rolling stay true to the dimensions you require and are straighter, with well-defined edges and corners. In the best case, you eliminate the need for straightening.

The dimensions of our cold-formed open sections are consistent from batch to batch, minimizing the need for adjustments in further processing.

Stronger yet lighter profiles, many grades to choose from

A cold-formed open section is generally lighter than a hot-rolled profile yet offers the equivalent bending strength. So, you can reduce the steel thickness and make your final product lighter and stronger with an optimized shape. This can also lower the environmental footprint of your structure.

Your choice of material is limited only by the choice of steels available in coils. You can increase the yield strength to 900 MPa or even choose weathering steels for your structure. By choosing the best steel grade quality, you can make a huge impact on the weight of the entire structure.

Improved surface qualities

Our cold-rolled open profiles have a smooth, finished surface quality that speeds up surface treatment. SSAB’s steels are pure micro-alloyed and designed to withstand extreme conditions. They also have excellent machining and welding properties.

Get the right shape, size and strength

When using cold-formed open sections, you can choose the shape with the best strength and dimensions that best fit your application. The shape can make all the difference in improving the function and usability of your product. SSAB can support you as early as in the design phase, and with our wide range of steels you’ll get the versatility you need to select the best open steel profiles, whether you’re looking for high-strength or weathering steels.

Cut waste on your next project

Reducing waste and splice welding makes sense in steel fabrication. This can be easily done by ordering the necessary lengths. By choosing a product that is optimized for your application in the right length, possibly perforated, you get a finished component in your hands – no need for time-consuming further processing.

What are steel profiles?

Steel profiles, also known as sections, are structural elements made of steel, known for their high strength and versatility. Thanks to their structure and mechanical properties, they are widely used in construction, industry, and many other sectors. They are used not only for building the frameworks of structures but also as reinforcing or finishing elements.

Their distinguishing feature is the variety of shapes and sizes, which allows them to be tailored to specific project requirements. Steel profiles can be hot-formed or cold-formed, which affects their technical parameters, such as strength or load resistance.

Types of steel profiles – what is worth knowing?

Steel profiles are divided into several basic types, depending on their cross-section and application:

Applications of closed steel profiles

Profile zamknięte stalowe, dzięki swojej wytrzymałości i uniwersalności, są powszechnie stosowane w różnorodnych konstrukcjach. Ich główne zastosowania obejmują:

Closed steel profiles, due to their strength and versatility, are widely used in various constructions. Their main applications include:

• Load-bearing structures – used as elements of building frameworks, warehouses, or bridges.
• Window and door frames – providing durability and stability, while allowing for aesthetic finishes.
• Drywall frames – ideal for partition walls and suspended ceilings.
• Technical installations – used in electrical and air conditioning works, especially when ventilation openings are required.

In which industries are steel profiles used?

Steel profiles find applications in many industrial sectors, including:

• Construction – from load-bearing structures to interior finishes.
• Machinery industry – used as components of machine frames and parts.
• Automotive – for constructing vehicle frames and structural elements.
• Energy – in supporting structures for energy installations.
• Furniture – as structural elements in modern furniture production.

Load-bearing capacity and strength of closed steel profiles

Closed steel profiles are valued for their high load-bearing capacity and resistance to stress. Thanks to their closed structure, they ensure an even distribution of forces, making them ideal for applications requiring stability and durability.

What influences the strength and resistance of closed profiles?

• Profile shape – rectangular and square cross-sections ensure optimal strength against forces acting from various directions, increasing the stability of the structure.
• Wall thickness – a greater wall thickness increases resistance to dynamic and static loads as well as mechanical damage.
• Material used for production – high-quality steel, especially hot-rolled, provides better strength parameters, such as resistance to stretching, compression, and external factors like corrosion.

How to match steel profiles to your needs?

Wondering how to choose steel profiles that meet all your needs? Here are some tips from ENVUN experts.

Profile type and its application

Choosing the right steel profile depends on the specifics of the project you plan to carry out. Profiles, also called steel sections, come in various variants tailored to specific applications. For closed profiles, popular types include:

• Rectangular steel profiles – ideal for frames and casings.
• Square steel profiles – used in structures where high aesthetic value is important.
• Cold-formed steel profiles – known for their precision and use in light load-bearing structures.

Larger cross-sections and thicker walls provide greater load-bearing capacity, while smaller dimensions are better for precise, aesthetic solutions.

Tips when purchasing steel profiles

When purchasing steel profiles, attention should be paid to the quality of workmanship, including uniform wall thickness and the absence of visible defects. Technical parameters such as load capacity and corrosion resistance are important, especially for external structures. The price should be in line with quality and fit within the budget, but it’s not worth compromising on material durability. Choosing a reliable supplier guarantees reliability.
