Maintenance of steel for turnstiles and other equipment in coastal areas can be challenging due to the presence of saltwater and high humidity, which can lead to corrosion. Proper maintenance is essential to ensure the longevity, functionality, and aesthetics of steel structures.steel can rust. Every form of steel can get rusted sooner or later. Rust is a form of corrosion that occurs when steel comes into contact with oxygen and moisture, typically in the form of water or humidity. The presence of saltwater or salt-laden air, such as in coastal areas, can accelerate the rusting process. When the steel rusts, a chemical reaction takes place where iron atoms on the surface of the steel combine with oxygen to form iron oxide, commonly known as rust. Rust weakens the steel and can eventually lead to structural damage if not addressed. However, there are several measures we can take to help protect and maintain steel in coastal environments as described below
It is recommended to create a maintenance schedule to clean steel surfaces of turnstiles and gates regularly to remove dirt, debris, and contaminants that can contribute to corrosion. It is desired to use mild detergents and water, and avoid abrasive materials that can scratch the surface. Rinse thoroughly and dry the steel after cleaning. When using any chemical cleaner, it is important to test it on a small, inconspicuous area of the steel surface first to ensure compatibility and avoid any potential damage. Additionally, always follow the instructions provided by the manufacturer of the cleaning product and use appropriate personal protective equipment if necessary. The widely used chemicals are as below
Water and mild detergent
For general cleaning of steel surfaces of turnstiles and gates, a mixture of water and mild detergent or dish soap can be effective. Use a soft cloth or sponge to scrub the surface gently. Rinse thoroughly with clean water and dry to prevent water spots or streaks.The widely used chemicals used are as below
Vinegar is a natural cleaning agent that can be used to remove light stains or mineral deposits from steel surfaces of turnstiles and gates. Dilute white vinegar with water, apply it to the surface, and scrub with a soft cloth or sponge. Rinse and dry afterward.
Ammonia can be used to remove grease, oil, or stubborn stains from steel of turnstiles and gates . Dilute ammonia with water, apply it to the affected area, and scrub gently with a soft cloth or brush. Rinse thoroughly with clean water.
Citric acid, commonly found in lemon juice or as a commercial cleaning product, can be used to remove rust or scale from steel surfaces of turnstiles and gates. Mix citric acid with water to create a solution, apply it to the rusted area, and let it sit for a while. Scrub with a brush or abrasive pad, rinse, and dry.
Baking soda is mildly abrasive and can help remove stains or light rust from steel turnstiles and gates. Create a paste by mixing baking soda with water, apply it to the surface, and scrub gently with a cloth or sponge. Rinse thoroughly and dry.
Commercial steel cleaners
There are commercial cleaners specifically formulated for cleaning and maintaining steel surfaces of turnstiles and gates. These products can be found in hardware stores or online. Follow the manufacturer’s instructions for proper usage and safety precautions.
Routine inspections are crucial for identifying signs of corrosion, damage, or structural issues in steel surfaces of turnstiles and gates. A visual inspection of the steel structure is recommended, looking for any signs of corrosion, rust, pitting, coating damage, or discoloration. Inspect welds, joints, connections, and fasteners for any signs of cracking, deformation, or looseness.It is important to look for the signs of rust or corrosion on the steel surfaces. Rust can appear as reddish-brown discoloration, flaking, or roughness. Pay attention to areas exposed to moisture, high humidity, or corrosive substances. By conducting routine inspections, we can identify and address any signs of corrosion, damage, or structural issues early on, allowing for timely repairs or maintenance actions. This proactive approach helps prevent further deterioration, extends the lifespan of the steel structure, and ensures the safety and reliability of the components.
Documentations and recordals
The detailed records of inspections, including photographs, notes, and any identified issues are to be maintained as per operation & maintenance manual of turnstiles and gates. This documentation will help track the condition of the steel structure over time and guide future maintenance and repair decisions.
