In the pharmaceutical industry, maintaining the highest standards of cleanliness and material integrity is crucial for both safety and compliance.
At Metapic, we provide specialised pickling and passivation services designed to meet the stringent requirements of pharmaceutical equipment and facilities.
Our treatments ensure that stainless steel surfaces remain free from contaminants and resistant to corrosion, helping to maintain product purity and operational efficiency.
Pharmaceutical manufacturing and processing equipment are often exposed to aggressive chemicals, high temperatures, and rigorous cleaning protocols.
Over time, these conditions can lead to the formation of corrosion, biofilm, and other surface contaminants, which can compromise the sterility and performance of the equipment. Pickling and passivation offer several critical benefits:
Established in Sheffield in 1960 Metapic have been an ever present company steel treatment company for over 60 years.
With years of hands-on experience, we offer a comprehensive range of cleaning and chemical passivation processes.
Our time-served expertise ensures high-quality results across various applications, providing reliable and effective solutions tailored to meet the specific needs of our clients.






At Metapic, we understand the unique challenges faced by the pharmaceutical industry. Our team is highly experienced in applying specialised pickling and passivation processes to ensure that your equipment operates at peak efficiency and safety.
We adhere to internationally recognised standards, such as ASTM A380 and A967, to provide reliable and consistent results for every project.
• Comprehensive Pre-Treatment Cleaning:
We begin with a thorough cleaning process to remove any visible dirt, grease, or residues from the surface of the equipment. This step is essential for ensuring that the pickling and passivation processes are fully effective.
• Precision Pickling:
Components are treated with a specialised pickling solution to remove any surface contaminants, including weld scale and oxide layers. This step restores the metal to a clean, reactive state, ensuring that the subsequent passivation process is as effective as possible.
• Neutralisation and Rinse:
After pickling, the equipment undergoes a neutralisation process to neutralise any remaining acids. This is followed by a thorough rinse with deionised water to ensure that all residues are completely removed.
• Passivation Treatment:
A passivation solution is then applied to the stainless steel surfaces, creating a uniform, passive layer that protects against future corrosion and contamination. This step is crucial for maintaining the sterility and durability of pharmaceutical equipment.
With extensive experience and a commitment to quality, Metapic is the trusted provider of pickling and passivation services for the pharmaceutical industry.
Our expertise ensures that your equipment is not only protected but also operates at the highest levels of cleanliness and efficiency.
