Outdoor handrails play a vital role in ensuring safety and accessibility in commercial and infrastructure projects. Whether it’s a school, stadium, or public park, selecting the right materials for handrails is crucial for both aesthetics and durability. In this article, we’ll explore the best materials for outdoor handrails, taking into account factors like longevity, maintenance, and design versatility.
Stainless Steel
Stainless steel is one of the most popular choices for outdoor handrails in commercial projects. It’s renowned for its exceptional durability and resistance to corrosion, making it ideal for withstanding the elements. Stainless steel handrails can endure harsh weather conditions, including rain, snow, and extreme temperatures, without rusting or deteriorating.
Various grades of steel are available, with two common options being 316 Marine Grade and 304 Grade Stainless Steel. While their visual appearances may appear similar, they possess distinct physical and chemical characteristics. When considering the application of steel in environments characterised by high chloride or saline levels, particularly in proximity to coastal areas, opting for 316 Marine Grade Steel is advisable. This choice ensures significantly prolonged durability compared to 304 Grade Stainless Steel, ultimately delivering enhanced value on your investment. Conversely, when exposure to acid and salt is not a primary concern, 304 Grade Stainless Steel proves to be an equally effective choice.
Hot-Dipped Galvanized Steel
Hot-dipped galvanized (HDG) steel is primarily used for outdoor handrails due to its durability, low-maintenance and relatively low cost. The galvanizing process involves coating the steel with a protective layer of zinc, creating a shield against the harshest elements. The longevity of hot-dip galvanized steel can vary based on the atmospheric conditions such as close proximity to salted roadways or corrosive zones. It is crucial to take into account the environmental factors when determining the appropriate thickness for a galvanized coating.
Aluminium
A lightweight and budget-friendly alternative to steel, aluminium offers excellent corrosion resistance. This material naturally forms a protective oxide layer on its surface, serving as a barrier against rust and corrosion. Aluminum handrails are particularly suitable for areas near the coast or locations with high humidity, as they won’t succumb to rust. Furthermore, its light weight, malleability, ductility, weight-to-strength ratio and non-toxic composition makes it suitable for a wide range of indoor and outdoor applications.
Additionally, aluminium handrails can be powder-coated in a variety of colours and finishes, offering durability and endless design possibilities. Aluminum needs intensive upkeep to get rid of smudges and prints, although satin finishes can assist in concealing such marks.
Wood
Wood stands as a robust, enduring, and cost-effective material with the versatility to be intricately shaped. While it is considered a traditional material, one of its most significant advantages is its timeless aesthetic appeal. Wood handrails seamlessly blend with natural surroundings and create a warm, inviting atmosphere. However, this material demands regular maintenance to preserve its appearance and durability. Failure to maintain them can result in rot, warping, or decay.
When contemplating the use of wood, ensure the railings and balustrades are manufactured from an exceptionally durable species for above-ground exterior applications and moisture-laden environments.
Choosing the Right Outdoor Handrail For Your Project
Selecting the right handrail material is a critical decision that impacts both safety and aesthetics. Stainless steel, HDG, aluminium and wood all offer unique advantages and cater to different project needs. When making your selection, consider factors such as the environment, budget, design requirements, and maintenance capabilities. By carefully evaluating these factors, you can ensure that your outdoor handrails not only meet safety standards but also contribute to the overall beauty and functionality of your commercial project.
