Yes, cutting galvanized steel can cause it to rust. This is because when you cut galvanized steel, its outer protective coating, recognized as zinc (a metal alloy), is removed from the surface, leaving it exposed and vulnerable to rust.
Additionally, cutting galvanized steel stirs up the zinc coating, leaving fragments of zinc mixed with oxygen and water, which encourages the creation of rust. Since rusty steel is weaker than normal steel, it can ultimately lead to structural failure over time.
To prevent this, make sure to paint or seal cuts in galvanized steel after they are made to protect them from corrosion.
Can you cut through galvanized metal?
Yes, you can cut through galvanized metal. Galvanized metal refers to steel or iron that has been dipped in molten zinc to protect it from corrosion. However, it can still be cut with the right tools.
Depending on the thickness of the metal and the desired finish, you have several options for cutting it.
One option for cutting thin sections of galvanized metal is to use a hacksaw. This is especially useful for smooth cuts and is inexpensive. For thicker sections of galvanized metal, you may need to use a tool such as an angle grinder.
This is also suitable for curves and shapes. You’ll also need to use a cutting disc with a specific grit rating that is appropriate for cutting metal, as the wrong type can damage the steel.
For more precise cuts, a band saw provides the most accurate results. The blades specifically designed for metal cutting, move the blade in a smooth motion, instead of the side-to-side motion of a hacksaw or the circular motion of an angle grinder.
Finally, if you have a large quantity of galvanized metals to cut and the accuracy of the cut is particularly important, a laser cutting can be used to achieve the desired results.
Is galvanized steel toxic to humans?
No, galvanized steel is not toxic to humans. Galvanized steel is steel that has been coated in zinc to prevent corrosion. This layer of zinc helps to protect against rust and other forms of corrosion, and does not pose any known health risks when handled or used in common construction materials.
Although some of the vapors released during the galvanizing process may be toxic, with proper precautions, these vapors can be avoided. In addition, there is no need to worry about breathing in any of the zinc particles, as they are generally too large to be inhaled and be a health hazard.
The only health risk that may come from using galvanized steel is if it is improperly recycled and contains lead or other hazardous chemicals or materials. In this case, the galvanized steel may be unsafe to handle without the proper precautions.
What are the symptoms of galvanized poisoning?
Galvanized poisoning, or zinc toxicity, occurs when someone is exposed to dangerously high levels of zinc. Common symptoms of zinc toxicity include abdominal pain, nausea, vomiting, fever, headache, and fatigue.
In severe cases, the symptoms may progress to include shortness of breath, chest pain, wheezing, coughing, and fever. Additionally, long-term exposure to zinc can lead to liver and kidney damage, respiratory failure, and death.
People are most commonly exposed to zinc through ingestion, inhalation, skin contact, or eye contact. Occupations such as welders, plumbers, and roofers who work with galvanized zinc-coated metals are at risk for the condition.
Other sources of zinc poisoning include the ingestion of coins or other objects containing zinc, the ingestion of certain dietary supplements and vitamins, and long-term contact with certain topical medications, such as zinc-containing antiseptics and coal tar products.
Treatment for zinc toxicity depends on the route of exposure and severity of symptoms, and may include oral administration of chelating agents, which bind to the zinc and help to expel it from the body.
If you suspect you have been exposed to dangerous levels of zinc, seek medical attention immediately.
