What common insurance cost mistakes do Structural Steel Contractors make?

The most expensive insurance mistakes for structural steel contractors are the ones you don’t know you’re making:

Not shopping annually. Loyalty to a single carrier costs structural steel contractors 20–35% in premium overpayment. Carriers adjust pricing based on market conditions — what was competitive last year may not be this year.

Wrong classification codes. Incorrect NCCI or ISO classification inflates your premium when codes overstate your hazard level and triggers audit penalties when they understate it. Annual classification review is the most commonly overlooked cost control measure.

Ignoring your EMR. Many structural steel contractors don’t know their experience modification rate or how it affects their premium. Every prevented claim improves your EMR — and your premium — for three years.

Buying minimum limits. The cheapest policy is not the best value if it leaves gaps that a single claim can exploit. Set limits based on realistic worst-case exposure, not regulatory minimums.
