Structural steel is the most commonly protected material but protection can include other materials such as sheet metal sheetrock composite panels and interior woods.
Fireproof paint for steel beams.
Flameoff fire barrier paint is an intumescent paint that can be applied to most building materials.
The worksite may be quite dirty.
Prior to application the steel may be coated with a primer although this is not necessary whereas the binding layer of an acrylic copolymer is required.
The spray is applied on site by machine spraying and the layer of thickness ranges from between 10 and 70 mm.
One of the benefits is that it can be installed as you go during the process of installing steel decks and beams.
