Hi there, We are trying to get the UL certification for our factory. If anyone of you can give us the phone number or address of the office who is in charge of that you bet that you win a new friend. And to make the favor complete we're trying to get the address and phone number of a company named GLASSTEEL. They are manufacturers pf copper clad laminates. Again, I will appreciatte a lot this help. Thanks. EDUARDO TOVAR DISEŅO DE CABLEADO IMPRESO
