Fire resistance of unprotected metal structures. This concept is crucial when assessing the fire resistance of steel structures that require fire protection treatment to achieve a rating of R15. According to SHNK 2.01.02-04 "Fire Safety of Buildings and Structures", roof structures in buildings classified as fire resistance level II must undergo fire protection treatment if the intrinsic fire resistance rating of each individual roof element is below R8. The intrinsic fire resistance limit
Corrosion protection for metal structures involves applying a protective layer based on polymer film-forming materials to a metal surface. Corrosion protection is vital for preventing the complete destruction of steel during its operational lifespan. Annually, corrosion renders up to 10% of steel structures unusable. Corrosion leads to two types of losses: Direct Losses - these occur when steel or…
Sandblasting for rust removal: preparing metal surfaces for corrosion protection and paint. Applying paint and varnish materials to metal structures is a specific sequence of actions and a very complex process that requires knowledge, professional training, and specialized equipment. First, the surface must be prepared. The most effective surface preparation method is abrasive blasting, commonly known as sandblasting. Various…
