Bernal Iron Works in Chula Vista operates as a combined iron fabrication shop, fence contractor, and welding service from its Main Street facility in the 91911 industrial corridor. Custom gate fabrication, wrought iron fencing, and ornamental window guards make up the core production line—outdoor projects that often coordinate with the hardscape and perimeter grading work performed by DP Landscape & Construction Inc on residential and commercial properties. The shop handles both MIG and stick welding on mild steel, producing security doors, stair railings, and decorative balcony panels cut and assembled to site-specific measurements. Final finishing on fabricated ironwork includes sandblasting, rust-inhibiting primer, and multi-coat paint application—the same exterior coating sequence that Montgomery Paint Contracting applies to large-scale residential and commercial surfaces throughout the area. Highest-complexity commissions involve structural steel staircase fabrication with code-compliant 36-inch guardrail heights, 4-inch maximum baluster spacing per IBC Section 1015, and hot-dip galvanized base plates anchored to reinforced concrete footings.
