San Diego County combines coastal construction, a large manufacturing base and a busy pipeline of commercial, life-science and infrastructure projects. To the east, the Imperial Valley is one of California’s most active regions for utility-scale solar.
Mona Steel serves both markets from Anaheim with structural steel, precision-cut parts, corrosion-resistant coatings for marine air and pile foundations for solar developments.
What we do for San Diego customers
Coastal-grade steel
Hot-dip galvanized and weathering steel options for structures exposed to salt air.
Commercial & life-science construction
Structural shapes, plate and miscellaneous metals for campus and commercial buildings.
Imperial Valley solar
C-piles, W-Beam piles and ground screws for utility-scale solar developments.
Protecting steel near the coast
Salt air accelerates corrosion. For coastal San Diego projects we help you select the right coating system, from G90 pre-galvanized sheet for sheltered applications to hot-dip galvanizing per ASTM A123 for exposed structures, so your steel lasts as long as your building.

San Diego FAQ
Do you supply solar projects in the Imperial Valley?
Yes. We supply C-piles, U-piles, W-Beam piles and ground screws for solar projects in Imperial County and across the Southwest.
What coating do you recommend for coastal steel?
For exposed coastal structures we typically recommend hot-dip galvanizing per ASTM A123, sometimes combined with a paint system (duplex coating) for maximum life. We will review your exposure and design life before recommending a system.
