General & Material Questions
1. What material do you use for custom 3D metal letters?
We use high‑grade 304 stainless steel as our standard material for all indoor 3D letter signage. It provides stable texture, scratch resistance, and long service life for interior corporate branding projects.

The two finishes create completely different visual styles for interior walls. You can learn more about brushed vs mirror‑polished stainless steel finish to decide the best match for your brand style.

Yes. With sealed installation and premium 304 material, our indoor letters perform well in humid and coastal adjacent environments without rusting or fading.

No. Especially for office and professional spaces, non‑illuminated stainless steel lettering remains a timeless classic design that never goes out of fashion compared with trendy lighting effects.
