Maintenance

Use a Steel-Cutting Blade for All Cuts

Evolution cuts like wood but needs a steel blade. Apply Black Sand touch-up paint to all cut ends immediately.

Fill Every Pre-Drilled Hole With Self-Tapping Screws

All bracket holes must be filled with Evolution No. 12 x 3/4 inch self-tapping screws for full structural integrity.

Remove All Metal Shavings Immediately After Cutting

Clear all metal chips from framing members and the job site, shavings cause rust staining and surface damage.

Always Reference Evolution Span Charts Before Framing

Steel spans exceed wood, always consult Evolution span charts before layout to ensure warranty-compliant structural performance.

Final Touches

Install fascia boards and trim pieces for a polished, professional finish.
