Most factory galvanized steel frames, outdoor guardrails and greenhouse brackets have smooth zinc-plated surfaces. Traditional zinc-rich primer cannot adhere tightly, and surface polishing treatment raises construction cost greatly. Cold spray zinc coating only needs simple manual rust removal, which is widely favored by engineering contractors in 2026.
