Steel structure fire protection coatings delay the temperature rise of steel components in a fire—steel loses most of its load-bearing capacity at around 550°C. Fire protection coatings form a carbonaceous insulating layer through thermal insulation or intumescence on heating, extending the time for components to reach the critical temperature to the fire resistance rating required by codes (commonly 1.0h / 1.5h / 2.0h / 3.0h). There are two main categories: intumescent (thin-film, expands 10–50 times on fire to form an insulating layer, thin coating, low weight and good appearance, suitable for indoor exposed steel structures); non-intumescent (thick-film, relies on its own low thermal conductivity for insulation, coating thickness up to 10–50mm, used for high fire resistance requirements or outdoor environments). Selection must follow codes—different component types (columns, beams, floor slabs) and different fire resistance ratings correspond to different coating thicknesses, and this thickness is determined by the product's own test report and cannot be applied across products. The design basis is mainly GB 14907, and the product's type test report and fire protection certification also need to be checked. This page summarizes original manufacturer data for fire protection coatings from various brands.

This page compiles original-factory technical data sheets by tag. The same model may appear under several tags at once (for example, a water-borne epoxy primer belongs to "water-borne", "epoxy" and "primer"), the more entry points a model has, the more easily it is found by search habits.
