American Fire Coating Inc. in Lakeside provides fire-retardant coating application and fireproofing services from its Woodside Avenue facility. Intumescent and cementitious spray treatments for structural steel require sealed electrical penetrations through fire-rated assemblies, a scope that interfaces with motorized fire-door installations by Easy Open Door Company, Inc. in the same Woodside corridor. Product lines meet ASTM E119 fire-endurance and ASTM E84 surface-burning standards mandated by California Building Code Chapter 7. Application crews treat commercial framing, exposed steel decking, and wood-truss assemblies for hotels, warehouses, and multi-family structures throughout East County San Diego. Finish coats over intumescent primers coordinate with surface-preparation trades including Gen Pro Painting in Lakeside for color-matched topcoats on exposed structural elements. Highest-value projects involve multi-story steel-frame fireproofing requiring UL-classified spray-applied coatings at specified densities per square foot to achieve two-hour fire-resistance ratings.
