The types of steel used in steel halls are: * **Structural Steel:** This is the most common type, forming the primary framework of the building, including beams, columns, and purlins. Grades like S235, S275, and S355 are frequently used, with S355 offering higher strength. * **Galvanised Steel:** Often used for purlins, girts, and sheeting in steel halls. The galvanisation process (coating with zinc) provides excellent corrosion resistance, which is crucial for the longevity of these components, especially in external and exposed areas. * **Sheet Steel (or Cold-Formed Steel):** Used for cladding the walls and roofs. This can be plain or profiled for increased strength and is often galvanised and painted for weather protection. * **High-Strength Steel:** In some larger or more complex steel hall designs, higher-strength steel grades might be specified to reduce the amount of material needed without compromising structural integrity. * **Stainless Steel:** While less common due to cost, stainless steel might be used in specific areas where extreme corrosion resistance is necessary, such as in food processing facilities or chemical plants. The specific grade and type of steel chosen depend on various factors including the span of the building, the loads it needs to support (wind, snow, operational loads), environmental conditions, and economic considerations.

Industrial construction, particularly in the field of steel hall structures, relies on the precise selection of materials whose mechanical and physical properties meet the requirements of a specific project. The key raw material used in this type of construction is Stale – iron alloy with carbon and other alloying elements. Suitable type of steel decides the strength, durability, and resilience of the entire structure. 

Structural steel – the foundation of a modern hall

Structural steel This is the basic material used in the construction of steel halls. It is iron and carbon composite, in which carbon content usually does not exceed 0.25%. Its main task is to ensure adequate tensile strength, squeezing and other mechanical loads. Thanks to high plasticity, Hardness i elasticityStructural steel allows for the creation of complex and weather-resistant supporting systems.

In industrial construction, non-alloy structural steel most commonly used bears the designations S235, S275 and S355 – they differ in the minimum tensile strength parameter (e.g. S355 means a minimum yield strength of 355 MPa). The choice type of steel depends on classification the object – its purpose, location, degree of exposure to loads and environmental conditions.

Classification of steel structures and steel grade

Industrial hall construction is divided into classes, depending on their complexity and purpose:

• Year 3 – less complex objects, with lower strength requirements. Non-alloy steel dominates here S235–S275which, despite its simple Chemical composition is characterised by good corrosion resistance and satisfactory durability.
• Year 2 – steel exposed to moderate loads and environmental influences. Both non-alloy and alloy steels are used low-level (np. S355), containing additional elements such as manganese, silicon, or nickel. They improve Steel propertiesespecially when it comes to Abrasion resistance and corrosion.
• Class 01 – advanced structures with high requirements. Higher grades of steel are used here, also with parameters exceeding S355, which are often referred to as special steelwith increased hardenability, mechanical strength and resistance to environmental influences.

Alloy steel – when strength isn't enough

Alloy steel contains, in addition to iron and carbon, other elements such as Chrome, Nickel, Molybdenum if manganeseThese add-ons significantly improve its Mechanical properties, affecting vulnerability Do processingand also increase corrosion resistance, abrasion and the effects of high temperatures. For alloy structural steels, parameters such as:

• Chromium – increases Hardness, Abrasion resistance and corrosion.
• Molybdenum – improves resistance to high temperatures and increases fatigue strength.
• Manganese – affects plasticity and weldability.

Alloy steels they are used in halls exposed to particularly harsh conditions – for example, in the chemical, energy, or heavy industries.

Stainless steel – resistant to corrosion and hygienic

Stainless steel this is special type of steelwhich is characterised by very high corrosion resistance thanks to the high content Chrome (above 10.5%). It also often contains Nickeland in some cases also molybdenum. These additives form a passive protective layer on the surface of the steel, which protects the material from the effects of moisture, chemicals, and temperature.

Stainless steel is particularly valued in the sector:

• grocery stores – due to hygienic properties,
• pharmaceutical – for ease of cleaning,
• chemical – for resistance to aggressive substances.

Although it is more expensive than standard steel, its use can significantly extend durability construction in difficult conditions

Galvanised steel – an additional protective layer

W industrial halls exposed to the elements are widely used galvanised steelShell with Zinc Protects steel from electrochemical corrosion. Galvanising can be carried out by the method:

• Fiery – dipping of elements in liquid zinc; ensures high durability,
• Galvanic – electrolytic zinc plating; cheaper, but less resistant.

This steel retains Mechanical properties base material, but gains more Weather resistancewhich is key, for example, in the agricultural or warehousing industry.

Tool steel – less popular, but important

Although it is not directly used for building hall frames, it is worth mentioning that tool steel, used in the production of machine parts, form, structural elements or technological installation components. Its Hardness, hardenability i Abrasion resistance making it ideal for precision applications in heavy industry.

FAQ - Frequently asked questions

1. What is steel and how is it made?

Steel is an alloy of iron and carbon, often with the addition of other alloying elements. It is produced in steelmaking furnaces.

2. How is steel classified according to its application?

Steel is divided, among others, into structural, tool, stainless, and spring steels, depending on their properties and application.

3. What is carbon steel?

Steel with a carbon content of up to approximately 2%, without significant alloying additions. It finds widespread use in construction and industry.

4. How do alloying additives affect the properties of steel?

They improve steel hardenability, wear resistance, hardness, and corrosion resistance, among other things.

5. What does a higher carbon content in steel mean?

A higher carbon content increases the hardness and strength of steel, but reduces its ductility.

6. What is the difference between low-alloy steel and carbon steel?

Low-alloy steel contains small amounts of alloying elements, which improves its mechanical properties and resistance compared to plain carbon steel.

7. What is the significance of steel markings?

Steel designations indicate its composition, strength class, and intended use – for example, S355 is structural steel with a yield strength of 355 MPa.

8. How to increase the hardness and strength of steel?

Processes such as quenching, heat treatment and appropriate selection of chemical composition are used, which improve the hardenability and performance parameters of the material.
