Wall-mounted handrail system with an organic Japanese design
The Comenza Sekkei ST-358 system is a wall-mounted handrail solution designed exclusively by Ryosuke Fukusada. Its geometry combines a cylindrical form that tapers away from the wall with a vertical prismatic element, creating a bracket with a smooth, balanced design and a strong visual identity.
Made of stainless steel, the ST-358 provides strength, durability, and refined aesthetics for contemporary architectural projects. Its compatibility with the Ø43 mm RP-1430 round tube makes it possible to create consistent handrail solutions within the Comenza range, combining functionality, safety, and design.
01. ORGANIC DESIGN WITH A TRANSITION BETWEEN CURVED AND PRISMATIC FORMS
The ST-358 stands out for its distinctive geometry, combining the softness of curved forms with the precision of a vertical prismatic element. This transition adds visual dynamism to the bracket and reinforces its sculptural character within the Sekkei Handrail range. Its design allows the handrail to function as both a practical safety element and a distinctive architectural detail.
02. DURABLE BRACKET FOR SAFE AND COMFORTABLE USE
Made of stainless steel, the ST-358 provides a strong and durable solution for wall-mounted handrail installations. Its design ensures stable fixing of the tube, helping to improve safety and user comfort. In addition, the system complies with the safety requirements established by the Spanish Technical Building Code (CTE), ensuring reliable performance in the project.
03. EASY INSTALLATION WITH A DESIGN OPTIMIZED FOR ASSEMBLY
The design of the ST-358 simplifies wall installation, allowing the bracket to be positioned precisely and securely. Its design provides easy access to the fixing points, simplifying the installer’s work and ensuring a clean, aligned installation that integrates seamlessly with the overall handrail system.
Advantages
01. EXCLUSIVE JAPANESE-INSPIRED DESIGN
The ST-358 is part of the Sekkei Handrail range, designed exclusively by Ryosuke Fukusada for Comenza. Its design language reflects the influence of Japanese design, where simplicity, balance, and attention to detail take centre stage. This distinctive identity makes the bracket an element of significant aesthetic value within the architectural project.
02. DISTINCTIVE GEOMETRY
The combination of a cylindrical transition base and a vertical prismatic element gives the ST-358 a distinctive aesthetic compared with more conventional solutions. This geometry creates a refined visual presence, adding personality to the system without overwhelming the overall design. It is particularly suitable for projects where construction details form an integral part of the architectural design.
03. COMPATIBLE WITH RP-1430 ROUND TUBE
The ST-358 is compatible with the Ø43 mm RP-1430 round tube, allowing consistent handrail solutions to be developed within the Comenza product range. This compatibility simplifies system configuration and ensures seamless aesthetic and functional integration between the bracket and tube, maintaining the visual continuity of the overall system.
Safety and regulatory compliance
COMENZA handrail systems are tested in accordance with the requirements of the Spanish Technical Building Code (CTE) to ensure the safety of end users. They are verified to pass static and dynamic load tests using the strength verification method with a variable action established by the CTE, applying a partial safety factor of 1.5. This is an essential requirement to ensure maximum safety and regulatory compliance of a railing system.
Installation
Components and accessories
The glazing kit allows LED technology to be integrated to illuminate the railing from the bottom of the glass, creating a distinctive and modern visual effect.
