Materials & Finishes

Metal, glass, and finish.

Choose the material and finish system that belongs on the opening. Samples are approved before fabrication begins.

Metals

Hot- & cold-rolled steel

Our primary material — strong, slender, and workable hot at the anvil and press. The basis of most doors, windows, and railings.

Insulated steel frames

For exterior doors and windows, our steel profiles are internally insulated to improve thermal performance while preserving the slim steel frame.

Wrought-style iron

Hand-scrolled, traditional ironwork for classical entries, gates, and ornamental pieces.

Bronze & brass

For handrails, hardware, and accents — warm, durable, and beautifully patinated by hand.

Stainless

Where corrosion resistance is required — exterior, coastal, or wet environments.

Finishes

These finish families can be used across architectural ironwork and steel furniture. The coating system follows the application, and custom color matching is available.

Exterior doors & windows

For exterior steel doors and windows, we specify high-performance architectural fluoropolymer coatings for UV stability, corrosion resistance, and durability. Standard color families include Black, Bronze, Espresso, and Wimborne White; custom color matching is available.

Fireplace doors & screens

Fireplace work uses high-temperature, heat-resistant coating systems selected for hearth applications. Available color families include Black, Bronze, Gold, and Gray, with custom high-temperature colors on request.

D’Hierro signature finishes

The five signature D’Hierro finish families — Black, Graphite, Iron Bronze, Metallic Brass, and Warm Silver — can be applied across architectural ironwork and steel furniture. The coating system follows the application; custom designer colors are available.

Custom samples & matching

Standard finish families are a starting point, not a limit. For custom colors, patina direction, or hardware matching, we prepare finish samples during drawings so the final finish is approved before fabrication moves forward.

Glazing

Insulated Low-E glass

Cardinal LoE³-366® insulated glass with argon gas fill is our standard exterior glazing, delivering thermal performance, solar heat control, and UV protection.

Specialty & safety glass

Optional low-iron glass, tempered glass, laminated safety glass, privacy glass, textured glass, and triple-pane insulated glazing are available.

Switchable smart glass

Glass changes from clear to frosted at the touch of a button for privacy, partitions, and wine rooms.
