When it comes to designing or remodeling an outdoor staircase, it is crucial to consider the functionality, durability, and safety of the hangers used to support the structure. The type of hanger chosen plays a vital role in ensuring the stability and longevity of the stairs. In this article, we will explore the different types of hangers commonly used for outdoor stairs and their importance in maintaining the structural integrity of the staircase.
1. Understanding the Role of Hangers in Outdoor Staircases:
Hangers, also known as stringer hangers, are the brackets or supports that connect the stair stringers to the building structure. These hangers bear the weight of the entire staircase, including the treads and risers, providing essential support and stability. In outdoor staircases, hangers face additional challenges due to exposure to the elements, such as rain, snow, heat, and humidity. Therefore, it is crucial to select hangers specifically designed for outdoor use.
2. Importance of Using Outdoor-Specific Hangers:
Unlike interior stairs, outdoor staircases are subjected to harsh weather conditions, temperature fluctuations, and moisture. These factors can cause untreated steel or standard indoor hangers to rust, corrode, or weaken over time, compromising the structural integrity of the stairs. By using hangers explicitly designed for outdoor environments, you ensure that your staircase remains stable, safe, and long-lasting.
3. Different Types of Outdoor-Specific Hangers:
a) Weather-resistant Steel Hangers:
One commonly used type of hanger for outdoor stairs is the weather-resistant steel hanger, often made of galvanized steel or stainless steel. These hangers are specifically designed to withstand exposure to moisture and are coated to resist rust and corrosion. Galvanized steel hangers go through a hot-dip zinc coating process, providing excellent protection against the elements. Stainless steel hangers, on the other hand, contain chromium, making them highly resistant to rust and corrosion.
b) Treated Lumber Hangers:
Another popular option for outdoor staircases is hangers made from treated lumber. These hangers are typically constructed with pressure-treated wood, which has undergone a process of chemical treatment to enhance its durability and resistance to rot, insects, and weathering. Treated lumber hangers provide an aesthetically pleasing option while ensuring the necessary strength and durability for outdoor staircases.
4. Factors to Consider in Hanger Selection:
When choosing hangers for your outdoor stairs, there are several important factors to consider:
- Durability and resistance to weathering are crucial factors in maintaining structural integrity.
- Properly sized hangers that can accommodate the weight of the stair treads and risers are essential.
- Ensure compatibility with the building materials and designs of your outdoor stairs.
- Adhere to local building codes and regulations regarding hanger selection and installation.
- Consult with a professional contractor or engineer to ensure the right hangers are selected for your specific project.
Selecting appropriate hangers for outdoor stairs is of utmost importance to ensure the stability, safety, and longevity of the staircase. By using hangers explicitly designed for outdoor environments, such as weather-resistant steel hangers or treated lumber hangers, you can protect your stairs from the damaging effects of weathering, corrosion, and rot. Always consider the specific requirements of your project, local building codes, and consult professionals to make informed hanger selections and ensure a successful outdoor staircase installation.
