Established in 1990, Pharmaceutical Stainless Supplies (formally Callaghan Industrial Stainless) specialises in providing a full stainless steel fabrication service to a variety of industries including Pharmaceutical, Health Care, Medical Devices, Food Processing, Catering and Construction Industries.

The company identified the need to specifically service the Life Sciences industries and to achieve this, in 2001 a new purpose built facility was constructed to accommodate the most up to date fabrication equipment.

In 2004 the company doubled the size of its premises to incorporate new design offices and again upgraded its fabrication equipment. The investment has allowed the company to become a market leader in high-quality, cost-effective stainless-steel products.

Pharmaceutical Stainless Steel Ltd continued to invest in 2011 by introducing a state of the art Trumpf CNC laser cutter. This transformed our manufacturing process and enabled the company to provide a comprehensive range of bespoke stainless products to exact customers specifications.

Additionally it reinforced the companies reputation for delivering the highest quality products on time while maintaining a consistent focus on meeting and exceeding customers’ expectations.

In 2013 Pharmaceutical Stainless Steel became the first stainless steel fabrication company in Ireland to offer a Multidirectional surface finish as standard on all products by introducing Timesaver Multidirectional Surface Finisher therefore offering best international practice for stainless steel surface finished.

In 2015 Pharma Stainless Ltd introduced their own in house degreasing and passivation process using a specific chemical range. The process complies to ASTM 380 & ASTM A967, and removes surface contamination on stainless steel and other alloys.
By removing free iron and other ferrous contaminants, passivation increases corrosion resistance and the chromium oxide film after welding or grinding which may produce external contamination.
The processt does not cause any change in colour or leave any residue and is used on 304 and 316 steel.

In 2017 Pharmaceutical Stainless Steel invested in a Trumpf Truebend 3100 CNC Press Brake with TruTops Boost software which allows our designers to simulate intricate sheet metal folded parts.

In 2018 Pharmaceutical Stainless Steel introduced Microsoft HoloLens to produce fixed and animated models of its products that allow our clients to view designs in hologram format.As this technology continues to evolve at a rapid pace we view it as the future in product design.

To ensure uninterrupted supplies to our customers Pharmaceutical Stainless Supplies Ltd  brought on stream additional storage capacity to secure our supply chain material

In 2025, Pharma Stainless commissioned with Solar Generation Ltd to install solar panels on the roof of our fabrication facility. Since the installation, 43% of the electricity we use is generated by solar power, reducing our reliance on electricity from the grid and increase our use of clean, renewable energy.

This has resulted in an estimated reduction of 20 tonnes of CO₂ emissions per year, making a significant contribution to reducing our carbon footprint.

As part of our commitment to sustainability, Pharma Stainless has acquired 8 hectares of coniferous forestry plantation. The trees naturally capture and store carbon from the atmosphere, removing an estimated 54.4 tonnes of CO₂ per year, while also supporting biodiversity and creating a more sustainable environment.

In 2026, PharmaStainless invested in a TRUMPF TruLaser Tube 3000 to increase our capacity and efficiency in the processing of stainless-steel tubes and profiles. The machine allows complex shapes, holes and contours to be cut accurately in a single process, reducing the need for traditional operations such as sawing, drilling and manual preparation.
