When dealing with door hardware finishes, two main code systems exist in the U.S.: ANSI and BHMA. Both help specify finishes but differ in what they describe.
ANSI (American National Standards Institute) finish codes usually describe only the color of the hardware finish. For example, a code like US3 refers to bright brass color but does not specify the base metal underneath.
BHMA (Builders Hardware Manufacturers Association) codes provide more detail. They describe both the color and the base material. This means a BHMA code tells you not just how the hardware looks but also what metal it’s made from or plated over.
BHMA codes are numeric, typically in the 600s. Each code corresponds to a specific finish and base metal combination. For instance:
BHMA 605 means bright brass finish on brass base metal.
BHMA 626 indicates satin chrome plated brass.
BHMA 652 shows satin chrome plated steel.
This level of detail helps manufacturers, architects, and contractors know exactly what material and finish they’re specifying or buying.
ANSI codes start with “US” followed by a number, like US3 or US10B. Most of these codes identify the finish color or appearance but not the metal underneath. For example:
US4 means satin brass color.
US10B refers to oil-rubbed bronze color.
Some ANSI codes do specify both finish and base metal. Notable examples are:
US32 for polished (bright) stainless steel.
US32D for satin stainless steel.
These exceptions align closely with BHMA codes 629 and 630, respectively. This overlap helps when stainless steel hardware is involved, ensuring clarity about the base metal.
Door hardware finishes come in several common types, each offering unique looks and qualities. Understanding these finishes helps you pick the right one for your project.
A polished or bright finish shines like a mirror. It’s buffed until smooth and reflective, making it eye-catching. You can see your reflection clearly on polished brass or stainless steel hardware. For example, BHMA 605 (bright brass) or BHMA 629 (bright stainless steel) finishes are polished and gleam beautifully. This finish is popular where a clean, shiny look fits the design.
Satin finishes have a matte or low-gloss look. Unlike polished finishes, satin won’t reflect your image. It’s smooth but soft to the eye, reducing glare and fingerprints. Satin brass (BHMA 606) or satin chrome (BHMA 626) are common satin finishes. This finish suits modern or industrial styles, offering a subtler appearance than polished.
Antique finishes mimic aged or weathered metal. They often combine satin surfaces with darker accents or blackened areas to create depth and a vintage feel. For instance, BHMA 609 (satin brass blackened, antique) shows this look. Antique finishes work well in traditional or rustic designs, adding character and warmth.
Living finishes are designed to change naturally as time passes. They develop a patina or wear pattern based on use and environment. The oil-rubbed bronze finish (BHMA 613, ANSI US10B) is a classic example. Each piece ages uniquely, creating a one-of-a-kind look. Living finishes suit projects where a natural, evolving style is desired, such as historic restorations or craftsman homes.
The BHMA finish codes range from 600 to 630, each representing a specific finish and base metal combination. These codes provide clarity about both the appearance and the material underneath the finish. ANSI codes often correspond to these BHMA numbers but mainly focus on color, except for some notable exceptions.
Here’s a breakdown of some common BHMA codes and their ANSI equivalents:
BHMA Code | ANSI Code | Finish / Base Metal |
|---|---|---|
600 | USP | Primed for painting - steel |
605 | US3 | Bright brass on brass |
606 | US4 | Satin brass on brass |
609 | US5 | Satin brass blackened (antique) on brass |
613 | US10B | Oil rubbed bronze on bronze |
619 | US15 | Satin nickel on brass or bronze |
626 | US26D | Satin chromium on brass or bronze |
629 | US32 | Bright stainless steel - stainless steel |
630 | US32D | Satin stainless steel - stainless steel |
This table shows how BHMA codes specify both finish and base metal, while ANSI codes mostly indicate finish color.
Bright Brass (US3 / BHMA 605): This finish shines like gold, polished to a mirror-like surface on brass. It’s commonly used in traditional or classic designs where a bright, warm look is desired.
Satin Brass (US4 / BHMA 606): Satin brass has a soft matte look, less reflective than bright brass. It offers a modern yet warm appearance, reducing fingerprints and glare.
Oil Rubbed Bronze (US10B / BHMA 613): This is a living finish that ages naturally over time. Initially dark with subtle copper undertones, it develops a rich patina, making each piece unique.
The same finish color can appear different depending on the base metal. For example:
Satin chrome on brass (BHMA 626) versus satin chrome on steel (BHMA 652) may show subtle texture or color differences.
Bright brass on brass (BHMA 605) looks warmer and richer than bright brass plated over aluminum (BHMA 666).
Understanding the base metal helps predict durability, corrosion resistance, and appearance over time.
Stainless steel finishes are notable exceptions in ANSI codes. They specify both finish and base metal:
US32 / BHMA 629: Bright (polished) stainless steel offers a sleek, reflective surface known for corrosion resistance and modern aesthetics.
US32D / BHMA 630: Satin stainless steel has a muted, matte look with the same durability benefits.
These finishes are popular in commercial and high-traffic environments due to their resilience and clean appearance.
Selecting the right door hardware finish is more than picking a color. It involves balancing aesthetics, durability, environment, and style to fit your project perfectly.
First, consider how the hardware will look. Do you want something shiny like polished brass or something subtle like satin chrome? Each finish reflects light and color differently, affecting the room’s feel.
Durability matters too. Some finishes handle wear, moisture, and chemicals better. For example, stainless steel finishes resist corrosion, ideal for outdoor or humid areas. Brass finishes may tarnish but can be polished to restore shine.
The environment plays a big role. High-traffic commercial spaces need finishes that resist scratches and fingerprints, like satin chrome or stainless steel. Residential spaces might allow more decorative finishes like oil-rubbed bronze or antique brass, which add character but require more care.
Your hardware finish should complement the building’s style. Traditional homes often suit warm tones like bright or satin brass. Modern or industrial designs favor cooler tones such as satin nickel or satin chrome.
Historic restorations benefit from living finishes like oil-rubbed bronze, which age naturally and enhance authenticity. For sleek contemporary spaces, polished stainless steel provides a clean, modern look.
Think about how much upkeep you want. Polished finishes show fingerprints and scratches easily, needing regular cleaning. Satin finishes hide wear better and require less effort.
Living finishes, like oil-rubbed bronze, change over time, developing a unique patina. If you like evolving looks, these are great. If you prefer consistent appearance, choose finishes that resist aging or are easy to refresh.
Residential: Satin brass (US4/BHMA 606) offers warmth and subtlety. Oil-rubbed bronze (US10B/BHMA 613) adds rustic charm. Bright brass (US3/BHMA 605) suits classic interiors.
Commercial: Satin chrome (US26D/BHMA 626) and satin stainless steel (US32D/BHMA 630) resist wear and look professional. Bright stainless steel (US32/BHMA 629) suits modern offices and healthcare settings.
Choosing the right ANSI/BHMA door hardware finish does more than just improve looks. It plays a key role in how well the hardware performs, lasts, and fits into a project’s overall design.
ANSI/BHMA finishes protect hardware from wear, corrosion, and environmental damage. For example, satin stainless steel (BHMA 630) resists rust in humid or outdoor settings, extending hardware life. Living finishes like oil-rubbed bronze (BHMA 613) develop a protective patina, which can hide scratches and wear over time. Using the correct finish ensures hardware stays functional and attractive longer, reducing replacement and maintenance costs.
Standardized finish codes guarantee uniformity across multiple hardware pieces. This is crucial in large projects where different manufacturers or batches supply components. When everyone specifies BHMA 606 (satin brass) or ANSI US26D (satin chrome), the final installation looks cohesive and professional. Consistency also helps in future repairs or additions, as matching finishes becomes straightforward.
Many building codes and industry standards require hardware finishes that meet certain durability and safety criteria. ANSI/BHMA finish codes ensure compliance by defining finishes tested for performance. For example, finishes on exit devices or fire-rated doors must meet specific standards for corrosion resistance and durability. Specifying finishes using these codes helps architects and contractors avoid costly code violations or rework.
High-quality finishes that maintain their appearance and function add value to properties. Well-chosen hardware finishes make a strong impression on buyers or tenants, signaling attention to detail and quality. For commercial buildings, durable finishes reduce downtime and maintenance expenses, improving tenant satisfaction. In residential settings, attractive finishes boost curb appeal and homeowner pride.
When working with door hardware, correctly identifying and verifying finish codes saves time and prevents costly mistakes. Both ANSI and BHMA codes appear on products, but reading them right requires some know-how.
Look for stamped or printed codes on the hardware itself or its packaging. BHMA codes are usually three-digit numbers in the 600s, such as 605 or 626. These tell you both finish type and base metal. ANSI codes start with "US" followed by a number or letter, like US3 or US10B, mainly indicating finish color.
For example, a lock marked BHMA 606 and ANSI US4 means satin brass finish on brass metal. If you see US32D, it signals satin stainless steel, matching BHMA 630. Knowing these conventions helps you decode the exact finish and material.
Use official BHMA and ANSI reference charts available online or in hardware catalogs. Manufacturer websites often provide detailed finish code guides. Apps or digital databases can scan product codes or model numbers to verify finishes quickly.
If uncertain, contact the hardware supplier or manufacturer for confirmation. They can clarify ambiguous codes or provide test reports showing finish composition.
Confusing ANSI and BHMA codes: Remember BHMA codes specify base metal; ANSI mostly color only.
Overlooking plating differences: Satin chrome on brass differs from satin chrome on steel, even if finish looks similar.
Assuming codes are universal: Some manufacturers use proprietary codes—always cross-check with standards.
Ignoring wear or damage: Old or worn finishes may obscure codes; verify with supplier if unsure.
Avoid these errors by double-checking codes, consulting official lists, and inspecting hardware condition closely.
The Builders Hardware Manufacturers Association website offers complete BHMA finish code listings and descriptions. ANSI standards documents detail US finish codes and their definitions.
Industry trade publications and specification guides often include updated finish code charts. Hardware distributors and manufacturers publish catalogs with finish information and cross-reference tables.
