Industrial-strength meaning

Hardware or software designed for fault tolerant operation. It mostly refers to software that has built-in safeguards against failure. For example, an industrial-strength operating system does not lock up the computer if an application fails. Industrial-strength features in a database (DBMS) ensure the quality of the data (see referential integrity and two-phase commit). Programs become industrial strength after being thoroughly tested in live user environments for extensive periods. See bulletproof.

Having a level of potency, concentration, or durability suitable for industrial tasks, as opposed to merely household tasks.
