Steel structures, due to their strength and versatility, are increasingly used in construction. They are durable, strong and robust, but require adequate protection from external factors. In the case of steel, among other things, temperature is important. How to protect steel in accordance with current standards?
Steel characteristics: Effect of high temperature on steel properties
Steel is used in the construction industry because of its specific properties. It is a material that can be formed into various shapes under the influence of high temperatures. In terms of composition, steel is an alloy in which the main components are carbon and iron, in addition, other elements are used in the production process, which give the final product specific desired properties. In practice, different grades of steel are available for sale, having specific mechanical and physical properties, dedicated to use in specific projects.
Under the influence of high temperatures, the mechanical properties of steel can change, and it becomes more vulnerable to damage, becomes more brittle, the resistance to loads decreases, so the risk of damage to structural components increases. Low resistance applies not only to extreme situations, such as fire, but also to high ambient temperatures, such as those found in production halls.
Standards and regulations: Overview of applicable fire safety requirements
The fire law in Poland very precisely defines what rules must be met for an object to be approved for use. Inspections and permits for the use of facilities are issued on the basis of specific legal standards. Currently, construction standards EN 1993-1-2 (Eurocode 3) and ASTM119 are in force. In addition, relevant EU legislation – the EU Construction Directive and national building regulations are applied.
For the construction of buildings, structural elements are used that have the appropriate tests and certificates, confirming the class of fire resistance.
Security methods
Fire protection of steel structures is a very important topic, as it affects the stability of the entire structure and the safety of people in the facility. Fortunately, there are methods that can effectively protect the structure from high temperatures.Among the technologies include:
- spray systems, this method is convenient to perform, and in addition, does not burden the steel structure, allows non-invasive application, can be used both outside and inside objects, the coating can be additionally painted with paints;
- fireproof painting, using, among other things. intumescent paints, their use requires appropriate preparation, initially the surface is protected by a special anti-corrosion paint, and only then is applied fireproof intumescent paint, and finally a topcoat, protecting the entire structure;
- fireproof enclosures made of special panels, thanks to them the steel structure is not only properly protected, but also becomes aesthetically and functionally enclosed, the core of the panel is made of magnesium-lime-silicate mixture, which is surrounded by a fiberglass mesh, covered with a layer of cellulose.
Choosing the right solution, tailored to the structural and functional needs of the object. A good solution is the help of specialists, such as https://rs-mal.pl/, who will help choose the most optimal option. In proper protection, knowledge, experience and the use of modern technology and equipment are important. RS-MAL combines modern aspects of performing fire protection with traditional, proven methods.
