How much does it cost per square meter for the construction of steel structure fireproof coating
In the fire safety guarantee system of steel structure buildings, steel structure fireproof coatings play a crucial role. The construction price varies due to various factors, among which the types of fireproof coatings, construction techniques, and usage also have significant differences. This is not only related to the characteristics of steel structure fireproof coatings themselves, but also closely related to the requirements of steel structure design specifications and the product quality and technical support of steel structure fireproof coating manufacturers.
Firstly, there are three common types of fire-resistant coatings for steel structures: thin coating, thick coating, and ultra-thin coating. Thin coated steel structure fireproof coating, generally with a coating thickness of 3-7 millimeters. The construction process is relatively simple, often using spraying or brushing methods. Before construction, it is necessary to ensure that the surface of the steel structure has been thoroughly cleaned and rust removed in accordance with the requirements of the steel structure design specifications, removing oil stains, dust, and rust, so that the surface is smooth, dry, and has a certain roughness to enhance the adhesion of the coating. When spraying, the spray gun should be kept close to the surface of the steel structure
Move the spray gun at an average speed at intervals of 15-30 centimeters to evenly cover the paint. Thin coating fireproof coatings usually require multiple sprays to reach the design thickness, and the spraying distance and time for each layer depend on the drying speed of the coating, usually 2-4 hours. The construction cost of this coating is relatively low, around 20-50 yuan per square meter. This is mainly due to its relatively low material cost, simple construction process, and fast construction speed. However, its fire resistance function is relatively weak among the three coatings, and it is suitable for steel structure building parts with low fire hazard and not particularly high requirements for fire resistance time. Some small industrial plants, ordinary warehouses, etc. may choose thin coating fireproof coatings. Thick coated fireproof coating for steel structures, with a coating thickness typically ranging from 8-50 millimeters. Due to its thick texture, the construction process requires higher standards. Spraying construction is commonly used, and high-pressure spraying equipment is required to ensure that the coating can be smoothly sprayed and evenly adhered to the surface of the steel structure. During the construction process, it is necessary to strictly follow the requirements of the steel structure design specifications for the thickness of the fireproof coating. The coating should be sprayed layer by layer, with each layer thickness controlled at around 5-10 millimeters. The spraying distance for each layer is relatively long, usually 24-48 hours, to ensure that the coating is fully dried and cured. The construction cost of thick fireproof coating is relatively high, about 50% per square meter-
120 yuan. This is because its material cost is high, the construction difficulty is high, and the construction period is long. But its fire prevention function is excellent, which can provide long-term protection for steel structures in the event of a fire. It is commonly used in large sports venues, exhibition halls, high-rise steel structure buildings and other places with high fire prevention requirements.
Ultra thin steel structure fireproof coating, with a coating thickness of less than 3 millimeters. Its construction process is similar to thin coating type, which can be sprayed or brushed. Before construction, the surface of the steel structure should also be strictly treated to comply with the steel structure design specifications. When spraying, pay attention to controlling the flow rate of the coating and the angle of the spray gun to ensure that the coating is even and smooth. The construction cost of ultra-thin fireproof coating is relatively high, about 80-200 yuan per square meter. The reason is that its material research and development cost is high, it has good decorative properties and high fire resistance, which can effectively prevent fire without affecting the appearance of steel structures. It is often used in places such as trade buildings and cultural buildings that have high requirements for building appearance.
Steel structure fireproof coating manufacturers play an important role in the entire process. High quality steel structure fireproof coating manufacturers can provide fireproof coating products that meet national standards and have good quality, and provide professional construction technical guidance. They will recommend suitable types of fireproof coatings for customers based on factors such as the type of steel structure, usage environment, and design requirements, and provide specific construction process plans. When choosing a steel structure fireproof coating manufacturer, its production qualifications, product testing lectures, past engineering cases, etc. should be examined to ensure that high-quality fireproof coatings and professional technical support can be obtained, thereby ensuring the fire safety of steel structure buildings, and also completing the construction of fireproof coatings within a reasonable cost range.
