Steel Spider was created in 1992.
It is said that spider silk has the strength of steel.
Any web-spinning spider can do it, it is a property of spider silk. When it is said that spider silk is stronger than steel, this does not mean the webs themselves as is. It means that if you had enough spider silk to weave into the same thickness as a steel cable, the spider silk would have a tensile strength five times greater.
