The Round Handrail Tube 1-2/3" OD / 42.4 mm is designed for modern railing, handrail, top rail, bar rail, and foot rail applications. Select the material and finish that matches your project requirements: Satin 316 Stainless Steel for heavy-duty stainless steel railing systems, or Black Matte Aluminum for a lightweight architectural aluminum option with a high-performance black painted finish.
The Satin Stainless Steel version is made from SS 316 stainless steel with a true 12 gauge / 0.102" / 2.6 mm wall thickness. It is the premium choice for strength, durability, exterior use, coastal environments, pool areas, and high-corrosion applications when maintained properly.
The Black Matte Aluminum version is made from 6005A-T61 aluminum, a heat-treated architectural extrusion alloy used for structural profiles where strength, clean extrusion quality, lower weight, and corrosion resistance are important. It is finished with an AAMA 2605-grade black architectural paint system for exterior UV exposure, color stability, and long-term architectural performance.

12 Gauge Satin Stainless Steel SS 316
The Satin 316 Stainless Steel version is built for customers who want a heavy-duty round tube with the strength, feel, and long-term durability of stainless steel. The tube uses a 12 gauge / 0.102" / 2.6 mm wall thickness, making it substantially heavier and more robust than thin-wall decorative tubing.
SS 316 stainless steel is the preferred stainless option for demanding railing environments because it provides excellent corrosion resistance, strong mechanical performance, and a premium satin brushed appearance. It is especially well suited for exterior railings, coastal projects, pool areas, commercial railings, and high-end residential installations when cleaned and maintained regularly.
This is the best choice when the priority is maximum durability, stainless steel construction, and a solid architectural handrail feel.
Black Matte Aluminum 6005A-T61
The Black Matte Aluminum version uses a premium 6005A-T61 architectural aluminum extrusion instead of stainless steel. 6005A-T61 is a heat-treated 6000-series aluminum alloy selected for railing profiles because it offers an excellent combination of strength, lower weight, corrosion resistance, and clean extrusion quality.
Compared with stainless steel, aluminum provides a major weight advantage, making long tube sections easier to handle, cut, transport, and install. This is especially useful for long handrail and top rail runs where reduced weight improves jobsite handling without giving up a clean architectural look.
The Black Matte finish is an AAMA 2605-grade black architectural paint system. This is not powder coat. It is a high-end painted aluminum finish selected for exterior UV exposure, color stability, corrosion resistance, and long-term outdoor performance.
Material & Finish Details
| Satin Stainless Steel | SS 316 stainless steel with satin brushed finish, 12 gauge / 0.102" / 2.6 mm wall thickness, approx. 1.75 lb/ft. |
| Black Matte Aluminum | 6005A-T61 architectural aluminum extrusion with AAMA 2605-grade black architectural paint system, approx. 0.49 lb/ft. |
| Weight Advantage | Black Matte Aluminum is approximately 70% lighter than the 12 gauge SS 316 stainless steel version, making long runs easier to handle and install. |
| Important Finish Note | Black Matte Aluminum is painted aluminum, not powder-coated stainless steel and not SS 304. Weight values are approximate and may vary slightly by production tolerance and cut length. |
Installation & Cutting Notes
- Standard dropdown lengths are pre-cut sizes.
- Exact custom cuts may require a custom setup fee.
- Lengths of 9 ft or longer ship by LTL freight in a wood crate. Our online system cannot calculate freight cost automatically — we will follow up after order placement with the freight cost, or you may contact us for a freight quote before ordering.
- To avoid freight shipping, keep all pieces under 7'10" and use a joiner to connect shorter lengths.
- Verify local code, railing height, handrail continuity, mounting conditions, and project-specific engineering before installation.
- Use care when cutting or handling painted aluminum to avoid scratching the Black Matte finish.
- Use proper stainless steel cutting tools and handling procedures when cutting Satin 316 Stainless Steel.
