On 31st July 1915 Mr. Watze Hilarius applied for a licence to start a factory for the production of wire hooks and barbed wire. This licence was granted by the local authorities in Haarlem on 28th September 1915. So, this date marks the founding of HILCO’s official activities in the Netherlands, exactly 90 years ago!

Today Hilarius is both an experienced and modern supplier of high quality welding consumables, covering the needs of welders in over 100 countries worldwide. Our activities are based on the character of the founder of this company, namely persistence and high performance in all activities.
