Welcome to Interstate Steel Center (ISC)

Since 1970, Interstate is the most trusted and specialized steel coil leveling toll processor on the west coast. Strategically located in the middle of Los Angeles, California in a 100,000 sq. foot facility, ISC solely focuses on leveling a wide variety of heavy and light gauge customer-owned steel coils.

Q: Why have Service Centers, Brokers, & OEMs partnered with ISC for over 50 years?

A: ISC is the ONLY toll processing leveler that does NOT (and will not) sell steel.
