Are New Castle Steel framing components pre‑fabricated?

Yes. Each framing kit is factory‑cut with precision‑drilled holes for fast and accurate on-site installation.

What finishes are available?

Our standard galvanized finish resists corrosion in all climates. Optional powder‑coat colors are available for custom aesthetics.

Can New Castle Steel framing work with existing deck joists?

Yes. The modular design integrates seamlessly with wood or composite joists, ideal for new builds and renovations.

How far can New Castle Steel joists and beams span?

New Castle Steel publishes span charts for six total-load ratings (50, 75, 100, 125, 150, and 200 PSF). Under the standard 50 PSF residential table, joists span up to 22 ft. (2" joists, all doubled, at 12" O.C.) with cantilevers up to 6 ft., and box beams span well over 20 ft. between posts depending on deck width and cantilever. Exact spans vary with joist spacing, cantilever length, and local load requirements — always confirm with New Castle Steel's official span charts or a local engineer for your specific project.
