Why Do SS Handrails Rust?

Stainless steel handrails are renowned for their durability, corrosion resistance, and aesthetic appeal. However, it can be perplexing when these seemingly robust structures start showing signs of rust prematurely. 

In this article, we will delve into the reasons behind the early rusting of stainless steel handrails and explore potential solutions. 

Composition of Stainless Steel

Stainless steel is an alloy composed of iron, chromium, nickel, and other elements. The high chromium content forms a protective layer on the surface, shielding the steel from corrosion. 

However, impurities in the manufacturing process or exposure to harsh environmental conditions can compromise this protective layer, making the handrail susceptible to rust.

Quality of Stainless Steel

The quality of stainless steel used in handrails plays a crucial role in their longevity. Substandard materials or poor manufacturing practices can result in a compromised protective layer, leading to accelerated rusting. 

KJA & SONS is a reputable company, that emphasizes the use of high-quality stainless steel in our products to ensure longevity and corrosion resistance.

Environmental Factors

Stainless steel handrails are often exposed to various environmental factors that can accelerate corrosion. Harsh weather conditions, high humidity, exposure to saltwater or chemicals, and air pollution can contribute to the breakdown of the protective layer on the stainless steel surface.

Surface Contamination

Contaminants like dirt, grease, or other materials can accumulate on the surface of the handrail, providing a conducive environment for corrosion. Regular cleaning and maintenance are essential to prevent the build-up of these contaminants and preserve the integrity of the stainless steel.

Poor Maintenance Practices

Neglecting regular cleaning and maintenance can significantly contribute to the premature rusting of stainless steel handrails. Establishing a routine for cleaning, inspecting, and addressing any issues promptly is crucial for preventing rust formation.

Galvanic Corrosion

When stainless steel comes into contact with dissimilar metals in the presence of an electrolyte (such as water), galvanic corrosion can occur. Proper insulation or the use of compatible materials in construction can mitigate this type of corrosion.

Passivation Process

The passivation process, which enhances the protective layer on stainless steel, may be compromised during manufacturing or installation. KJA & SONS, with its commitment to quality, ensures that the passivation process is meticulously carried out, contributing to the longevity of its stainless steel products.

Innovations in Corrosion Resistance

Companies like KJA & SONS are at the forefront of developing innovative solutions to enhance the corrosion resistance of stainless steel handrails. Advanced coatings, improved manufacturing processes, and ongoing research contribute to the development of products that withstand the test of time.


Understanding the factors contributing to the premature rusting of stainless steel handrails is crucial for implementing effective preventive measures. Regular maintenance, high-quality materials, and adherence to best practices in manufacturing and installation are essential. 

KJA & SONS is a prominent company, that exemplifies these principles, showcasing a commitment to delivering stainless steel solutions that stand up to the challenges of corrosion. By combining industry expertise with innovative approaches, they continue to be a trusted name in the pursuit of durable and aesthetically pleasing stainless steel handrails.
