Handrail
A handrail or guardrail is a metal structure used for protective purposes to prevent humans or vehicles from falling from heights. Iron handrails are commonly used in streets to separate main and secondary lanes, on overpasses or underpasses for vehicles, and on dam crests to prevent people from falling. They are also used in refineries and power plants to protect industrial machines and equipment. In general, in areas where the height difference exceeds 70 cm, handrails, guardrails, or parapets should be installed to prevent the risk of falling. The handrail can be coated in either hot-dip galvanized or industrial paint, but typically, due to environmental aesthetics and the importance of urban architecture, industrial paint is used. It is implemented in various designs, which we will explore further below.

Handrail coating
Handrail coating can be done in two ways: hot-dip galvanizing or industrial paint (epoxy or alkyd). Both methods are used to prevent structural damage such as rust and corrosion, but there are differences between the two methods. The parameters that differ in these methods include: cost, lifespan, humidity of the installation site, environmental tone, aesthetics, and so on. The paint coating has a lifespan of 8 to 10 years depending on the climate of the region, after which it needs to be repainted. However, the hot-dip galvanizing coating has a lifespan of about 25 to 30 years, after which the structure needs to be replaced.
Applications of Handrails
- Next to bridges
- Next to fluorescent poles
- Around dams
- Along highways
- Around overpasses and underpasse
