02. SECURE FIXING WITH A GEOMETRIC AESTHETIC
Its design ensures stable fixing of the handrail tube, providing safety and functionality for everyday use. Its AISI 316 stainless steel construction provides strength and durability, while its straight-line design allows the system to integrate seamlessly into projects where the handrail forms part of the geometric language of the space.
03. EASY INSTALLATION WITH FLAT TUBES
The configuration of the ST-335 FLAT facilitates the installation of handrails with square or rectangular tubes, allowing for direct and precise wall mounting. Its geometry ensures proper alignment of the entire system and helps achieve a clean, stable, and visually consistent finish.

Advantages
01. COMPATIBLE WITH SQUARE AND RECTANGULAR SOLUTIONS
The ST-335 FLAT is compatible with square or rectangular tubes, expanding the design possibilities within the Stand-Rail range. This compatibility makes it possible to create handrails with a more linear and contemporary aesthetic, ideal for projects where straight lines and geometric forms predominate.
02. WELL-DEFINED FINISH WITH STRAIGHT LINES
Its straight-line design gives the overall system a clean and precise appearance, reinforcing the geometric aesthetic of the handrail. This feature allows the system to integrate seamlessly into contemporary architectural spaces, where construction details must maintain visual consistency with the rest of the project.
03. MADE OF AISI 316 STAINLESS STEEL
The ST-335 FLAT is made of AISI 316 stainless steel, ensuring strength, stability, and durability in both indoor and outdoor environments. This high-quality material ensures reliable performance over time while maintaining a refined and durable finish.
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.
