How to create a fire-resistant floor in steel structures
Thread Content
I would like to ask fellow sailors: for a Class A factory building constructed with steel structures, where the second-floor floor is covered with patterned steel plates, is it necessary to have a non-combustible floor? If we need to do it, how should we proceed?
The floor in explosion-proof areas is made of non-sparking material, usually by applying an epoxy coating. However, grid systems have not been seen to use this approach; galvanized steel grids are generally chosen. If it must be done, epoxy coating is recommended.
Each specific issue should be addressed individually; for Category A items, rotational molding or spraying can be considered to ensure good corrosion protection, and any areas that peel off later should be repaired promptly
This actually creates potential problems; it’s better not to use such a design when working with concrete
How can I determine whether a completed floor is non-combustible? Also, in such cases, can steel platforms not be used in places where gases heavier than air are released?
Epoxy resin floors. Another option is to consult the design institute
Explosion-proof areas require conductive floors, and epoxy resin is not conductive.
For the patterned plate section, applying an anti-static coating as required by the design usually meets the requirements
Patterned steel plates are elastic, making it difficult for other materials to bond to them perfectly; applying epoxy resin simply can lead to damage. This regulation was originally intended for buildings; large petrochemical facilities use metal grating plates or patterned steel plates
