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 Regular cleaning It is recommended to create a maintenance schedule to clean steel surfaces 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, 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 White vinegar Vinegar is a natural cleaning agent that can be used to remove light stains or mineral deposits from steel surfaces. Dilute white vinegar with water, apply it to the surface, and scrub with a soft cloth or sponge. Rinse and dry afterward. Ammonia Ammonia can be used to remove grease, oil, or stubborn stains from steel. 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 Citric acid, commonly found in lemon juice or as a commercial cleaning product, can be used to remove rust or scale from steel surfaces. 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 Baking soda is mildly abrasive and can help remove stains or light rust from steel. 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. These products can be found in hardware stores or online. Follow the manufacturer's instructions for proper usage and safety precautions. Inspection Routine inspections are crucial for identifying signs of corrosion, damage, or structural issues in steel structures. 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. This documentation will help track the condition of the steel structure over time and guide future maintenance and repair decisions.

Salt spray test, also known as the salt fog test or salt mist test, is a standardized corrosion resistance test conducted to evaluate the performance and durability of materials, coatings, and surface treatments. It is commonly used in various industries, including automotive, aerospace, marine, and manufacturing. The test involves subjecting the test specimen to a highly corrosive environment created by spraying a saltwater solution (typically a solution of sodium chloride, NaCl) onto the surface. The solution is atomized and dispersed as a fine mist, which settles on the specimen and exposes it to a concentrated salt solution. The purpose of the salt spray test is to simulate the effects of saltwater exposure or other corrosive environments that materials and coatings may encounter during their service life. The test helps manufacturers and researchers assess the corrosion resistance, protective properties, and durability of their products, coatings, or surface treatments. During the test, the specimens are typically evaluated for corrosion-related issues such as rust, blistering, pitting, or other forms of degradation. The test duration can vary depending on the specific standard or industry requirements, ranging from a few hours to several weeks. Different standards, such as ASTM B117 and ISO 9227, provide guidelines and specifications for conducting salt spray tests. These standards outline the test conditions, preparation of specimens, evaluation criteria, and reporting methods to ensure consistent and comparable results across different testing facilities. It's important to note that the salt spray test is just one of many tests available to assess corrosion resistance. Depending on the specific application and requirements, additional tests may be performed, such as cyclic corrosion testing, immersion testing, or outdoor exposure testing, to provide a more comprehensive evaluation of the material or coating's performance in real-world conditions.

Turnstiles for coastal areas are selected after lot of technical works. The coastal areas present unique challenges due to the harsh marine environment, including exposure to saltwater, high humidity, and salt-laden winds. When it comes to selecting materials for coastal areas, it is important to consider their resistance to corrosion and their ability to withstand these challenging conditions. The primary concern in coastal areas is corrosion. Select materials that have excellent corrosion resistance and can withstand prolonged exposure to saltwater and high humidity. Stainless steel, aluminum, galvanized steel, copper, and titanium are commonly used due to their corrosion-resistant properties. Coastal areas often experience extreme weather conditions, including strong winds, salt spray, and UV radiation. Choose materials that are durable and can withstand these elements without significant degradation or damage. Materials such as stainless steel, aluminum, and copper alloys are known for their durability in coastal environments.  Regular maintenance is crucial in coastal areas to prevent or mitigate corrosion. Some materials require more maintenance than others. We need to consider the long-term maintenance requirements of the chosen materials, including cleaning, inspections, and protective coatings, to ensure their continued performance and longevity. In addition to functionality, the aesthetic appeal of materials is often a consideration in coastal areas, especially for architectural and decorative applications. Materials such as stainless steel, aluminum, copper, and their alloys offer a range of finishes and appearances that can enhance the visual appeal of coastal structures. It is important to comply with local building codes, regulations, and industry standards when selecting materials for coastal areas. These standards often include specific requirements for corrosion resistance, structural integrity, and environmental considerations. When it comes to selecting metals for coastal areas, it is important to consider their resistance to corrosion caused by the harsh marine environment. Saltwater, high humidity, and exposure to salt-laden winds can accelerate the corrosion process. Some metals that are commonly used and known for their suitability in coastal areas are as mentioned below:
