Product Information

In this office building, which is still under construction, Arup was able to reduce the amount of fire protection on the outside of the building from what would have been required if it had followed prescriptive guidance. As a result, it was able to install far more glazing. Both types of board may be used in limited external conditions but the advice of the manufacturer should be sought. In Summary, Intumescent steel paint thermally insulates structural steel in a fire, stopping premature collapse of the building. The material used for sweep/whip blasting is finer than the one used for sand blasting and cleaning steel profiles of rust. This is to make sure that the galvanising is not damaged, and never exposes any raw steel underneath. 4. WEATHERING

Atmospheric corrosivity categories and examples of typical environments (BS EN ISO 12944-2 [1]) Corrosivity category Important fire test standards when using intumescent coatings on structural steel constructions are European Union: EN 13381-8 (Replaces national Standards in Europe) and United Kingdom: BS 476-20/21 (Commonly referred to in EU, Middle and Far East). What Is an Intumescent and How Does Intumescent Paint Work? Today, modern durable protective coatings are available which, when used appropriately, allow extended maintenance intervals and improved performance.If you are going to keep interior steel beams exposed, you have to make sure they are protected against fire if you want building regulation officers to sign off on your build. Interior steel beams have to be protected against fire for at least 30 mins and this is one of the reasons we tend to box RSJs in. A coat of this paint dries to the touch in 30 minutes, after which you’ll truly fall in love with the results. The paint coat has a unique shimmer and texture like no other. Steel structures often behave better in fire than suggested by standard fire tests, because of the development of alternative load paths. On the other hand, complex and unusual steel structures might behave worse than standard fire tests suggest, owing to thermal expansion of the surrounding materials. These factors can be assessed by structural fire engineers, and this can deliver significant safety and aesthetic benefits and cost savings if considered early.

Therefore, steel beams need fire protection. If you don’t suitable protect them, your insurance will become invalid and more importantly, it can be dangerous and disastrous! RSJs are produced by being rolled from a single piece of structural steel (S355 grade) to maintain structural integrity and are used to support walls and floors when making an opening in a load bearing wall or when building an extension. These steel beams have good machinability, corrosion resistance, and weldability properties. In cases where a compartment wall is built on the under-side of a steel beam, the wall should continue past the beams to the underside of the floor slab, unless the beam is protected to at least the same standard as the compartment wall using fire protection other than intumescent paint.

Passive & reactive fire protection to structural steel. Lennon, T. & Hopkin, D. Building Research Establishment We narrowed down only steel-worthy paints so you can skip hectic research and head straight to shopping. Here are the 7 best paints for steel. Rank Both solvent-based and water-based coatings can be used to achieve attractive surface finishes. If a decorative or bespoke finish is required, this should be included in the specification. Thin film intumescents have the added advantages that they can easily cover complex shapes and post-protection service installation is relatively simple.
