What are the fire and corrosion prevention measures for steel structures?
With the pursuit of individuality and fashion in modern buildings, many super high-rise buildings and long-span buildings will use steel structures. As steel structures are used in open-air buildings, they have to endure the wind, sun and rain all the year round. At this time, the fire prevention and anti-corrosion ability of steel structures is particularly important. So how to take fire prevention and anti-corrosion measures in the process of steel structure processing ? Let's have a look at Guangtong steel structure!
Due to the poor corrosion resistance and fire resistance of steel, it is necessary to do a good job in the construction of steel structure buildings, such as spraying antirust paint or fireproof coating, which is of great significance to extend the service life of steel structure, improve the durability of steel structure and improve economic benefits. The protection of steel structure mainly includes fire prevention measures and corrosion prevention measures.
The fire resistance of steel structure is poor. Therefore, the steel structure members in the building need to be protected against fire. Such as coating concrete or other fireproof materials outside the steel structure, or spraying fireproof coating on the surface of components. For the fire protection materials of steel structure, the materials with good thermal insulation performance or large heat capacity shall be selected, which are qualified by the national authoritative testing agency.
The anti-corrosion measures for steel structure can be generally divided into the following four categories:
1. The weathering steel with corrosion resistance shall be used, and the corrosion resistance of the steel itself shall be used.
2. Long term anti-corrosion methods such as hot-dip galvanizing and hot-dip aluminum composite coating are used for steel surface treatment to make the anti-corrosion life of steel structure reach 20-30 years or even longer.
3. Coating method is adopted, i.e. coating (spraying) paint or other anti-corrosion coating on the surface of steel structure, with a durability of 5-10 years.
4. Adopt cathodic protection measures for underwater or underground steel structures.
