Our history

On 28 September 1915, Mr. Watze Hilarius started manufacturing wire nails and roof slates. Hilarius has since built a strong tradition of serving its customers, who are now located in approximately 100 countries across the world. This has resulted in strong partnerships with welders, welding engineers, purchasing managers, field technicians, and construction and production managers. This has been achieved either by direct contact or through our extensive global network of trained distributors. You can find the registered brand name Hilco, in combination with the powerful green colour, anywhere, even in places where you would least expect it.

At Hilarius we consider welding to be people’s business. We are committed to enhancing relationships with our business partners, which effectively optimizes our mutual success in business. We take things further to become closer, and are committed to making strong connections.
