Strips
Copper Bars
Copper bars have numerous industrial applications: in plumbing and electrical engineering equipment, mechanical engineering equipment, decoration, etc.
General Specifications
Copper bars' chemical, physical and mechanical properties, tolerances and/or limitations comply to variety of standards, as for example EN 13601, JIS H 3250/JIS H 3140, ASTM B 187. Their production is monitored throughout all stages with the application of management system certified by Lloyds Register as complying with the requirements of standards ISO 9001:2008.
