Im looking for a metal that performs like a measuring tape or those old slap bracelets. Working on a new product for my client who needs a strip that can be stored in a rolled position but can be unfurled for a long strip to be hung. I assume its some type of tempered spring steel run through a forming die for concave body. I need it to be thicker. does anyone know where i should start looking? Most measuring tape manufacturers wont work with much thicker materials.
1mm is VERY thick for spring steel. Why does it need to be that thick? The weight for it to hold something should be very strong either way. 1mm steel is not going to want to curl up.
I’d recommend finding a vendor who can do custom springs and describe to them your needs (spring force, length, hanging load) and see what they can do.
