What is corrosion protection of steel structures?
All steel structures, including roofs, can be corroded by external factors such as weather conditions or chemicals. In order to prolong the life of steel surfaces, it is necessary to take care of their effective protection. Check out how to do it!
How to protect steel structures from corrosion?
All steel structures are subject to the risk of damage by corrosion. Thanks to modern technologies, this risk can be significantly reduced with proper design and protection of the structure. At the stage of designing steel structures, care should be taken to select the right anti-corrosive materials and simplify the form. At this stage you should also take care of the proper joining of components. What if the steel structure is already made, but you are still concerned about the occurrence of corrosion on it? Here external anti-corrosion coatings in the form of paints and primers come to the rescue. Another treatment that effectively protects metals from corrosion is galvanizing.
What anti-corrosion paints do professionals use?
Painting steel surfaces with anti-corrosive paints is the most popular type of protection. It is a relatively cheap and effective solution. Thorough coverage of the surface with a layer of paint increases the resistance of the structure to corrosion and other types of damage. The color and type of paint can be selected individually by professionals. Among the most popular anti-corrosion paints are:
- two-component paints,
- single-component paints,
- gruntoemail.
Two-component paints include polyurethane or epoxy paints. Their advantages include good coverage, fast drying and excellent anti-corrosion properties. Single-component paints, on the other hand, are a larger group that includes paints such as silicone, acrylic, polyvinyl, chloride and alkyd. Many of them are used for painting elements that can be affected by high temperatures, such as furnaces and chimneys. Another type of preparations are modern primers that guarantee a durable and flexible coating that is resistant to UV rays. Their biggest advantage is that there is no need for a primer coat.
Galvanizing – a permanent way to protect against corrosion
Zinc plating is a more advanced process than painting to guarantee the durability of corrosion protection. It involves bathing any steel components in specially prepared baths, where the following processes take place:
- degreasing of components,
- etching,
- rinsing,
- fluxing of components,
- tinning,
- passivation and cooling.
Note that in the case of galvanizing steel structures, special technological openings must be prepared to allow the free flow of zinc.
Durability of corrosion protection
Any protection against corrosion has a certain durability. Protection by galvanizing is said to have a high durability, which, depending on the corrosivity class of the structure and weather conditions, can range from ten to as much as 100 years. Anti-corrosion paints on the market also boast a high durability, which can be “adjusted” through the thickness of the coating. It is estimated that painting guarantees anti-corrosion durability for up to 50 years. To extend the life of the protections, each steel component should be carefully cleaned before painting or galvanizing. The most common cleaning methods are:
- sandblasting,
- glazing,
- hammering,
- tanning.
The cleaned and then washed, dusted and degreased surface is ready for corrosion protection.
