Due to long-term exposure to high-salinity and high-humidity environments, desalination plants have extremely strict requirements on building materials. Steel grating has become one of the indispensable materials in desalination projects due to its excellent corrosion resistance, strength and durability. So, in these special environments, what points should be paid attention to in the structural design and installation of steel grating?
Material selection In desalination plants, the corrosion resistance of materials is crucial. Usually, hot-dip galvanized steel grating or stainless steel grating is the preferred material. These materials can not only resist the corrosion of seawater, but also ensure the long-term use of the grating in harsh environments. The thickness of the galvanized layer determines its corrosion resistance, and the appropriate coating thickness should be selected according to project requirements.
Bearing capacity design In desalination plants, there are many equipment and pipelines, and steel grating needs to bear the weight of the equipment and the operating pressure of workers. Therefore, when designing, the appropriate steel grating specifications should be selected according to the actual load requirements of the plant. Commonly used heavy-duty steel gratings have stronger bearing capacity and can ensure that the platform will not be deformed or damaged during long-term use.
Drainage and ventilation design The grid structure of the steel grating can not only ensure good ventilation, but also quickly remove the moisture generated in the factory to prevent water accumulation. When designing, attention should be paid to the grid spacing, which should ensure safe walking and effective drainage. In areas with high drainage requirements, steel gratings with larger openings can be selected.
Anti-slip design In humid environments, platform anti-slip is an essential safety requirement. When designing, you can choose a toothed steel grating, whose surface anti-slip treatment can effectively prevent workers from slipping during operation and improve the overall safety of the factory.
Preparation before installation The steel grating should be quality checked before installation to ensure that the surface galvanizing is uniform, rust-free and damage-free. Before installation, detailed measurements and pre-arrangements should be made according to the structural drawings of the factory to ensure that the size and position of each steel grating are accurate.
Connection and fixing The fixing of steel grating is usually bolted or welded. Bolt connections require high-strength, corrosion-resistant bolts to ensure that they will not loosen in a humid environment. For areas with large load-bearing capacity, it is recommended to use welding to ensure the firmness and stability of the connection.
Anti-corrosion treatment Although steel grating has good anti-corrosion properties, the original protective layer may be damaged by cutting or welding during installation. Therefore, the cutting parts and welding points should be treated with anti-corrosion coating after installation to avoid corrosion caused by local failure.
Safety protection measures During the installation process, workers should wear necessary protective equipment and ensure that there are temporary guardrails or other safety devices on the installation platform of the steel grating to avoid accidents during high-altitude operations. During the installation process, people should try to avoid walking on the steel grating that has not been fixed to prevent slipping.
Regular inspection and cleaning During the use of steel grating, salt, debris, etc. may accumulate on the surface. It is recommended to clean and maintain it regularly to ensure its anti-corrosion effect and long-term performance.
Repair of anti-corrosion layer For steel gratings with partial zinc layer shedding or damage after long-term use, the anti-corrosion layer should be repaired in time to avoid further deterioration of corrosion problems and affect the service life of the grating.
The application of steel grating in seawater desalination plants is highly favored due to its excellent anti-corrosion performance, bearing capacity, drainage effect and safety. Through reasonable structural design and scientific installation methods, it can ensure the long-term stable operation of steel grating in harsh marine environments. If you are preparing for the construction or renovation of a seawater desalination plant, you might as well choose steel grating, which will provide reliable protection and efficient performance for your project.
