A railing placed on the wall of a staircase that runs parallel to the slope of the stairs is most commonly referred to as a handrail. Handrails provide support and assistance for people using the stairs, helping to prevent slips and falls. They are an important safety feature in any building with staircases.

Purpose and Function of Handrails
Handrails serve several key purposes on staircases:
– Provide stability and support – Handrails give stair users something sturdy to grasp onto for balance and stability. This is especially important for elderly, disabled, or injured people with mobility challenges.
– Prevent falls – By giving stair users something to hold, handrails help prevent slips and falls, especially important on long or steep stairs. Stair falls can lead to serious injury.
– Provide guidance – Handrails help guide people up and down the stairs, giving a directional path to follow. This helps prevent missteps off the side of stairs.
– Aid with accessibility – Handrails allow people with mobility impairments or who use wheelchairs to safely use stairs. They provide assistance for balance and support.
– Meet safety codes – Most building codes and safety regulations require handrails on stairways over a certain number of steps. Handrails are an important safety feature.
Properly installed handrails are angled to be easy to grasp and allow users to slide their hand along the rail smoothly as they ascend or descend. They are mounted at a height between 34-38 inches above the tread of the stairs for optimal use. Placements on both sides of a staircase allow lefthanded and righthanded use.
Handrail Materials and Design
Handrails can be constructed from various materials, each with their own pros and cons:
– Wood – Traditional material, provides good grip, often used for decorative railings. Requires proper finishing to be splinter-free.
– Metal – Very durable, but can be slippery unless textured. Stainless steel resists corrosion. Requires proper mounting anchors.
– Glass – Sleek, modern look, but can shatter and lacks grip. Often has another rail added.
– Plastic/Acrylic – Lightweight but sturdy. Very easy to clean and usually textured. Can crack over time.
– Composite – Blended materials like resin, recycled plastic, etc. Durable, weather-resistant, good grip.
The design and shape of handrails can vary as well:
– Round – Most common, easy to grasp shape. Diameter between 1 1/4” to 2”.
– Oval – Curved shape fits the hand well.
– Square – Provides a flat, stable surface, but can be uncomfortable to grasp.
– Three-sided – Triangle shape that resists spinning/rotation.
– Molded – Shaped specifically for hand grip with finger curves.
– Ornate – Decorative railings with carved shapes and patterns.
The ends of the handrails also need protective terminations, such as returning it to the wall, a volute curl, or safety caps. This removes sharp ends and prevents catching clothing.
Handrail Installation
Properly installing handrails requires precision measurements, the right mounting hardware for the wall material, and checking for compliance with local building codes. The main steps are:
– Taking exact measurements for length of railing needed.
– Drilling holes for mounting bolts into wall studs or using special anchors.
– Screwing brackets into studs if needed.
– Attaching end pieces like volutes before mounting rail.
– Lifting rail into place against wall and bolting into brackets.
– Testing strength by putting weight on railing.
– Adding protective caps on ends.
For curved or custom railings, a metal core can be bent into shape before wood or other materials are attached around it. Getting measurements right is crucial for proper installation.
Building Codes for Handrails
Installing handrails, including their height, size, and termination, requires following safety codes and regulations. Some key United States building codes include:
– IRC – International Residential Code
– IBC – International Building Code
– ADA – Americans with Disabilities Act standards
General guidelines per most codes:
– Mount height of 34-38 inches measured above stair tread
– Clearance of minimum 1 1/2 inches between railing and wall
– Able to resist loads of 200 pounds or more
– Terminate in newel posts or be returned to wall
– Smooth surfaces with no sharp edges
Local jurisdictions can amend codes with specific handrail requirements so verifying regulations is essential. Safety inspectors will check for compliance.
Evolution of Handrails
Handrails have been present in staircases for centuries, evolving in design over time:
– Middle Ages – Rope or wood rails first used in castles and manors
– 17th & 18th Century – Ornate carved wood handrails popular in Victorian era
– 19th Century – Wrought iron handrails allow decorative curves and patterns
– Early 1900s – Tubular steel pipes emerge as stronger alternative
– Modernist period – Sleek metal rails like brushed steel become popular
– Postmodern era – Glass and acrylic rails provide minimalist look
– Present – Ergonomic shapes and new materials focus on grip and comfort
Building codes also progressed safety requirements and standard dimensions. ADA requirements added focus on accessibility. While handrail styles keep changing, their functional purpose remains the same – provide stair users added stability and support.
Common Handrail Terminology
Some common architectural terms used around handrails include:
– Baluster – Vertical supports that hold up the handrail, similar to posts
– Fillet – Concave curved joint between handrail and balusters
– Volute – A spiral scrollshape on the end of a handrail
– Wreath – Ring or curved wrapping where the rail terminates
– Easing – The rounded taper of each tread edge that meets the railing
– Newel – Structural post anchoring main stairway angle changes
– Gooseneck – A curved end of a rail that projects out decoratively
– Rosette – A round stylized carving for decorative effect
– Boss – A protruding disk on the railing covering a joint
Handrail Care and Maintenance
To keep handrails looking their best and functioning safely:
– Inspect regularly for signs of loosening, damage, splintering etc.
– Tighten any loose joints, screws, brackets immediately
– Clean surface dirt and grime regularly with mild, non-abrasive cleaners
– Re-finish wood rails as needed to avoid splintering
– Seal any minor cracks or nicks in railing
– Replace severely damaged or deteriorating rails
– Ensure railing can still bear adequate weight loads
– Check that balusters, newel posts remain securely in place
– Make any needed adjustments to meet changing building codes
Proper care protects longevity, aesthetics, and safety. Consider replacing outdated or damaged handrails.
Handrail Alternatives and Substitutions
In some cases, existing handrails may not suit the needs of a space. Some alternatives include:
– Add a second railing at another height for children or shorter people
– Replace a railing on only one side with a wider double railing
– Use offset railing brackets to bring railing height into code compliance
– Replace round railing with a flatter shape for improved grip
– Swap a decorative railing for a grippy textured surface one
– Extend railing farther down on lower steps for added safety
– Add tactile cue strips for heightened awareness of steps
– Install another grab bar on wall above railing
– Replace custom railing with modular prefabricated system
– Mount a separate flat rail to existing balusters for dual grip
Any alterations should aim to improve stair safety and meet current building codes. Consulting a contractor is advised to ensure proper installation.
Significance of Handrails
Though often overlooked, handrails play an important role in buildings:
– Provide critical fall protection on stairs
– Help prevent liability-related injury lawsuits
– Give people stability and confidence using stairs
– Allow accessibility and ease for all ages and mobility levels
– Often required by law for safety in public structures
– Represent thoughtful design for user wellbeing
– Can make stairs safer during power outages or emergencies
– Allow safe usage of beautiful architectural spaces
– Give users reassurance and comfort in unfamiliar settings
– Help define and identify stairway routes and pathways
Simple handrails make everyday use of stairs easier and more secure for everyone. This essential safety component benefits all who enter a building.
Conclusion
Handrails serve the vital purpose of providing balance and support for people using staircases. Mounted to the wall along the stairs, handrails give users an extended arm to grasp to stabilize themselves. They help prevent dangerous slips and falls. Codes require minimum heights and strength to optimize safety. Handrails come in many styles, shapes, and materials to match functionality with aesthetics. But their core role remains promoting safe passage up and down stairways. Handrails are an often overlooked necessity that make everyday stairs safer.
