Planning focus
Aluminum and steel systems differ in weight, corrosion behavior, finish and structural design.
Budget drivers
Custom powder coating, fascia, drainage and long spans can increase cost.
Operations and lifecycle
Periodic inspection of finishes, connections and drainage helps preserve service life.
Safety and code boundary
Structural capacity and connections are project-specific engineering issues.
Educational planning only. Actual construction, code compliance, regulated systems, hazardous materials and safety-critical work require qualified professionals and current local requirements.
