Protection of metal structures from fire is in some way a barrier that is created on the surface of a metal structure. It usually withstands the full effect of the fire and high temperature for a long time, under such a coating the metal melts much more slowly, its bearing capacity is maintained for as long as it takes to extinguish the fire. Fire protection is required in each case is different. Here are some types of fire protection for metal structures that are most often used. By the way, did you know that aluminum – you can buy quality products for any business, even for fire protection.
one. Plaster is a coating applied to structures, on a special reinforced steel mesh. It is not expensive, but provides good fire resistance, about 2 hours. It has the following disadvantages: it increases the load on the foundation, the need to additionally treat the grid with an anti-corrosion coating, the plastering process is very complicated, it cannot be used on farms and when protecting communications.
2. Brick cladding – it makes sense to do in those structures where not only fire protection is required, but also additional reinforcement. Fire resistance will provide for two and a half hours.
3. Fire retardant compounds and paints – the most optimal protector from fire. The compositions are thermally expanding, it foams applied to the coating, it becomes larger in volume, fire protection is up to 2 hours.
