Thinner steel structure fire-retardant coatings offer superior decorative effects.

Fire-resistant coating for steel structures, applied to the surface of steel components, expands and foams upon contact with fire, forming a charred, heat-insulating protective layer. This layer isolates oxygen, slows down the rate at which the steel structure heats up, and prevents rapid temperature increase in the steel components, thereby enhancing the fire resistance of the steel structure. It can meet fire resistance limits ofThe requirement for fire protection ranging from 0.5 to 2.5 hours applies to the supporting single-layer columns, beams, roof load-bearing members, and evacuation stairs in buildings with fire resistance rating of Grade 1; as well as to the steel structural components of supporting single-layer and multi-layer columns, beams, roof load-bearing members, and evacuation stairs in fire resistance ratings from Grade 2 to Grade 4. The technical specifications comply with the national standard GB 14907-2002.

Thinner Structural Steel Fire Retardant Coating Application Technique
Prior to the application of fire-resistant coatings, the steel components should be thoroughly cleaned and rust-removed, and the anti-rust primer should be applied in accordance with the design requirements and current national specifications. All dust, oil stains, and other debris on the steel surface should be completely removed. Fire-resistant coatings should be applied before interior decoration and under conditions that prevent damage from subsequent construction. During the application, shielding protection should be provided for walls, doors and windows, mechanical equipment, and other components that do not require fire protection. Before painting, the paint should be thoroughly mixed. If the paint is too thick, add water as needed to thin it to a suitable consistency for application, without dripping. This product is suitable for coating by spraying method. At an air pressure ofThe even spraying is carried out using a hopper with a diameter of 6 to 8 mm at a pressure of 0.4 to 0.6 MPa. The thickness of a single coat should be sufficient to cover the base surface, generally not exceeding 1mm; the next coat can only be applied after the previous one is completely dry. From the second coat onwards, the thickness of each coat can be slightly increased, but it should not run.
Important Precautions for the Application of Thin-Film Fire Retardant Coating on Steel Structures
During the construction process and before the coating dries and cures, the ambient temperature should be maintained at5 to 45°C, relative humidity should not exceed 90%, and air should be well-ventilated. Construction is not recommended when condensation appears on the surface of the components. During the construction process, always measure the coating thickness according to the fire resistance limit. When spraying, ensure consistent spray direction to avoid uneven textures and color variations due to light reflection. This product is a water-based fire-resistant coating, so the coating should be kept indoors or under a shelter to prevent rain during and after application.
According to the introduction, the price of fire-resistant coatings is only a few dozen yuan. However, many street gangsters and some irresponsible decoration companies cut corners, creating potential safety hazards for fire prevention. Therefore, consumers must check whether the construction is carried out according to standard procedures before the ceiling and other concealed projects are completed, and they must also inspect the application of the fire-resistant coatings.
What is the fire-resistant coating's combustion performance?
Fire-retardant coatings are classified based on the combustion performance levels of construction materials. To strictly control the quality of fire paints, the state categorizes their combustion performance into two grades: Grade One and Grade Two. This is to prevent enterprises from passing off substandard products and ensure that fire retardant coatings achieve their intended fire-resistant effects.
How are flame-retardant coatings classified by their combustion performance levels?
Currently, domestic enterprises can produce flame-retardant paints with a burning performance reaching level two, with the cost price approximately at...Above 8,000 yuan per ton. Genuine fire-retardant paint, when exposed to flames from torches or similar sources, will foam and swell extensively, with the surface gathering into raised lumps without any burn damage within minutes. Counterfeit products, on the other hand, barely foam and often show a significant amount of falling off and chipping.
