The Handrail Base Flange is a high-quality, durable hardware component designed to anchor structural tubing to walls, floors, or other flat surfaces. As a critical point of connection within a modern railing system, this component ensures that structural handrails remain safely and rigidly anchored to their mounting surfaces. The flange features a heavy-duty flat base plate with precision pre-drilled holes, allowing for an efficient and secure installation using standard screws or structural bolts. Combining heavy-duty functionality with sleek aesthetic appeal, it delivers the necessary load-bearing stability required to meet building safety codes.
Manufactured from premium materials, these robust stainless steel handrail fittings are engineered to accommodate standard round tube dimensions, including outer diameters of 33.7mm, 42.4mm, and 48.3mm. The structural collar has a designated height (H), a total base diameter (D), and an integrated side hex-screw mechanism to lock the inserted pipe firmly into place. To ensure optimal performance across diverse environments, the flange is available in high-grade AISI 304, AISI 316, and Duplex SS 2205 stainless steel options. Offered in both elegant satin and mirror polished finishes, this versatile component provides strong corrosion resistance and design flexibility across residential, commercial, public, and industrial settings.

Q1. What is the primary purpose of a Handrail Base Flange in a railing system?
A: The Handrail Base Flange serves as the primary structural connection point between a handrail tube and a flat mounting surface, such as a wall or floor. It distributes physical loads evenly across its flat base plate, providing the essential support needed to keep the railing stable, secure, and code-compliant.
Q2. Which stainless steel grade should I select for my project's environment?
A: The ideal material grade depends on localized environmental exposure and the required level of corrosion resistance:
Grade 304: Best suited for indoor installations, climate-controlled commercial spaces, and residential interior staircases.
Grade 316: Highly recommended for general outdoor use, urban handrails, and environments exposed to regular weathering.
Duplex SS 2205: Engineered specifically for severe marine environments, industrial facilities, and coastal infrastructure facing heavy saltwater exposure.
Q3. What specific tube dimensions are compatible with these flanges?
A: These flanges are precision-sized to fit industry-standard architectural round tubing with outer diameters of 33.7mm, 42.4mm, and 48.3mm. Please confirm your exact piping dimensions prior to ordering to ensure a perfect mechanical fit.
Q4. How is the handrail tube secured inside the flange collar?
A: Installation is straightforward and weldless. The flange is first anchored to the wall or floor using screws or bolts through its pre-drilled base holes. The handrail tube is then inserted directly into the collar and locked firmly into place by tightening the integrated side grub screw, establishing a rock-solid, permanent mechanical hold.
