اسبانيا steel strap شركات الاستيراد من / معدن حديد فولاذ اسبانيا

I need to make a spring from an ASUS 304 stainless steel strap. The size of the strap is 3x0.8mm and the dimensions of the spring are 150mm in diameter, and 40mm in pitch. It is a spring that is used to make a toy and has slightly strange proportions. There are a few more specifications I could provide in a pdf file.
