1. Acceptance of Terms and Technical Reference Scope
By accessing CustomAddressSigns (https://customaddresssigns.com), you agree to these Terms of Service. Our engineering articles, material comparison tables, and interactive sizing calculators provide general architectural and fabrication guidance. Because municipal ordinances vary, property owners and contractors remain responsible for verifying minimum numeral height and placement with their Authority Having Jurisdiction (AHJ) and local fire code inspector prior to fabrication.
2. Custom Plaque Proofs, Foundry Tolerances & Natural Stone Variation
- Dimensional Foundry Tolerances: Green-sand cast bronze (C83600) undergoes natural thermal shrinkage of approximately 1.2%–1.5% during solidification; finished cast dimensions carry a standard commercial tolerance of ±1/8 inch, whereas CNC waterjet aluminum plates hold ±0.015 inch.
- Lithological Variation: Quarried Welsh slate, Pennsylvania bluestone, and granite exhibit natural mineral veining, bedding plane variations, and subtle shade shifts that distinguish genuine stone from synthetic composites.
- Proof Approval: All custom plaque proofs should be checked carefully for spelling, directional suffixes (
NW,Ln,Ct), and bore center-to-center spacing before pattern making or V-carving begins.
3. Masonry & Column Installation Safety
Heavy bronze and stone plaques mounted overhead or onto masonry piers must be anchored into sound structural substrate using stainless steel threaded studs and two-part structural epoxy rated for local freeze-thaw and wind loads. Direct questions regarding these terms to info@customaddresssigns.com.
