About CustomAddressSigns — Metallurgy, Lithology & Optical Typography

CustomAddressSigns bridges classical foundry pattern-making, metamorphic stone carving, and modern environmental graphic design so homeowners, architects, and HOA boards can specify permanent plaques without guesswork.

Why Generic Retail Plaques Fail Outdoors

Most mass-market “metal” or “stone” address plaques sold online cut corners that become painfully visible within three winters: secondary zinc die-castings blister underneath thin bronze-tinted paint in coastal air, crushed-limestone polyester resin warps in afternoon sun, and automated computer typesetting crams long street names against decorative borders without optical kerning.

We built CustomAddressSigns around verifiable ASTM metallurgical and lithological benchmarks, pairing interactive layout calculators with field-proven masonry anchoring protocols.

ASTM B62 & B209 METALS

True Foundry & Marine Alloys

Every metal specification distinguishes molten C83600 red brass castings (85% copper, 5% tin) from cold supersonic 5052-H38 marine aluminum finished in AAMA 2604 fluoropolymer/polyester powder coats.

ASTM C406 GRADE S1 STONE

Freeze-Proof Quarry Selection

We specify unfading Welsh and Vermont Grade S1 slates (<0.25% ASTM C121 water absorption) and monumental granites carved with self-shadowing 60-degree V-grooves and 23.75k gold leaf.

1:5 STROKE & KERNING MATH

Wayfinding Typography

Two-line plaques follow strict 32%–38% secondary cap-height hierarchies, open counterforms on 6/8/9, +10% to +16% relief tracking, and 0.45x border margins aligned with IFC §505.1 visibility rules.

SAE 316 + ASTM C881 EPOXY

Split-Face Masonry Engineering

From hollow CMU stone veneers to historic brick piers, our anchoring guides pair molybdenum SAE 316 stainless blind studs with Delrin drainage standoffs and non-expanding structural epoxy.
