Different solutions to comply with the requirements of the project for stability and resistance to fire. Culleré i Sala, S.L. integrates in the design and calculations of the metallic structure the required resistance to fire and stability needed for the project, therefore optimising the structure for these loads. We can offer a large array of solutions for the passive fire protection of the metallic structure.
For fire resistance up to R-60 we use treatments based on the application of intumescent painting, which afterwards will need to be protected with a finishing enamel layer.
At Culleré i Sala, S.L. we always apply anticorrosion treatments, based on primers compatible with intumescent painting. This is actually key for the durability and appropriate resistance of the intumescent treatment.
For high resistance to fire we recommend the usage of perlite and vermiculite-based spray foams, which with the right thickness allow up to R-180.
