Steelong system is made of steel, which goes through the galvanizing process- this is accomplished by immersion process into the melted metal according to STN. Steel is currently the best beam construction material in the building industry. It resists natural phenomena- fire, wind, water or earthquake.
Why steel is preferable to the classical building materials is its fire resistance. While steel only partially loses hardness at temperatures above 500 ° C, wood ignites itself without sparks already at about 175-275 ° C. This means that wood starts to fire easily while steel construction gives you much more time for fire extinguishing. Time is the most valuable when a fire starts to burn.
Fire tests have shown that steel structures are able tofulfill all requirements for fire protection, even thoughtheir construction is economical and fast.
