From design to commissioning

we take care of everything

We manage your project from design through to commissioning, always striving for consistent, high-grade quality. Our skilled engineers translate your needs and processes into the right product, within the constraints of sustainability and applicable regulations.

Kuipers Woudsend’s strength lies in taking responsibility from the design phase onwards, across all stages: detailed design, procurement, production, quality inspection by NoBo, transport and installation. Throughout your project you are guided by a dedicated project manager at Kuipers Woudsend.

Why clients choose Kuipers

Kuipers Woudsend is more than a supplier of stainless steel products. Where required, we take full responsibility for your project – from the first conversation and detailed design through to production, inspection, transport and on-site installation. You have one dedicated contact who knows your project inside out.

We have been doing this for over 60 years for many loyal clients who keep coming back. Thanks to short lines of communication, a flexible approach and craftsmanship proven in practice, we are a reliable partner for complex, custom stainless steel solutions – in the Netherlands and beyond.

Personal

You have one dedicated contact throughout the entire project. No being passed around, no confusion over who is responsible for what. Your project manager at Kuipers Woudsend knows your assignment from start to finish.

Committed

We are involved from the very first conversation. From functional design and detailed engineering to procurement, production and commissioning – we take responsibility for the entire process. Not just at handover, but at every step.

Reliable

We do what we say. Our way of working is built on short lines of communication and minimal overhead. That translates into clear agreements, realistic schedules and results that match what we agreed together.

Expertise

Our engineers design and calculate storage tanks, pressure vessels, piping and complete process installations. They work with 3D design software (Inventor), know the relevant regulations (PED, ATEX, EHEDG) and have extensive hands-on experience. Cost savings of up to 25% have demonstrably been achieved in practice through close collaboration between our Engineering and Procurement teams and those of our clients.

Quality

Our quality is measurable and testable. We work with certified welders and mechanics, under ISO 9001:2015, SCC, EHEDG and Kiwa BRL-K756/03. All products are built under controlled conditions in our own workshop and undergo thorough testing before delivery.

Safe delivery

Our production facility has large doors and a lifting capacity of up to 90 tonnes. Kuipers Woudsend has excellent road access and is situated directly on open waterways. Large installations can be transported to their final destination by truck or by ship.

Our vision

Kuipers Woudsend is one of the best producers of stainless steel products and process equipment in the Netherlands. From standard to highly customised stainless steel products from a client-focused market approach. Our products are realised and optimised in close collaboration with you.

Our mission

With passion, driven by our craftsmanship, we advise, develop and produce high-grade stainless steel products and process equipment. We do this for various markets in the Netherlands, Europe, Asia and America.

Since 2026

Johannes Kuipers started in 1964 as the local blacksmith in the Frisian village of Woudsend. Today, under the name Kuipers Woudsend, the company has grown into a leading manufacturer of high-grade stainless steel products. From one employee then to over 90 employees in 2016. We produce semi-finished and end products. Companies can come to us for professional welding, structural work, press work, sheet metal work and engineering.

Frisian mentality

Frisians have a rich history and their own unique character. Straightforward, yet full of heart. They have no time for flattery, boasting or dishonesty, and believe firmly that all people are equal. And they don’t just talk – they act. Johannes Kuipers made whatever needed to be made from metal. Simply because he was asked to. That Frisian no-nonsense attitude, craftsmanship and dedication are still very much present today. Come and visit us – we’ll make it happen. Clients often say: ‘Wat kinne se eins net?’ (‘What can they actually not do?’)

Proven quality

Quality is something for those who make things. Quality also means working with our products and equipment for years without issues. And quality is measurable and testable. We demonstrate this through our certifications, standards, tests, measurements and inspections.

We are happy to have tests and trials conducted by third parties, and we cooperate fully in continuous periodic testing of our products throughout the full lifespan of the installation. All in the interest of lasting quality. Kuipers Woudsend works with certified welders and SCC-certified mechanics.

Projecten

Cream sauce mixing tanks

For a major dairy producer in the south of the Netherlands, Kuipers built two mixing tanks for cream sauces. Fully adapted to EHEDG requirements, with optimised agitators and Duplex material chosen for its resistance to the corrosive effects of salts.

Nickel alloy drying towers

Kuipers produced three drying towers from a special nickel alloy for drying permeate — an aggressive whey by-product for which standard stainless steel is unsuitable. Delivered to sites in the Netherlands, Germany and the United States.

Zuivel- & Voedingsmiddelen

Kuipers produced manure tanks on a self-supporting chassis with a calibrated weighing system — built for heavy-duty use in the agricultural road transport of animal manure and liquid fertilisers.
