Welcome to the Impact Ireland (Metals N.I.) Resource Centre. We have developed many articles and data sheets to assist you when choosing the correct metal grade for your requirements. We have compiled metal conversion tables and tolerance specifications as well as instrumental grade index and strength range documents. If you require any additional information relating to our metal resource files or have any other questions about our metal and engineering plastic ranges, please contact our team.
