70×70mm Square Post Railing System – Sturdy 3.0mm Wall | JIMEI Glass Railing Profile

This 70×70mm post stair railing system, featuring a 3.0mm wall thickness, is designed to pair seamlessly with 120×30mm handrails. Equipped with a 140mm-wide welded base plate and decorative caps, this heavy-duty railing solution delivers superior ground anchorage and lateral stability, making it an ideal choice for large-span installations, high-traffic areas, and outdoor applications. It is widely used in premium residences, commercial complexes, and public buildings where both safety and visual impact are paramount.

Core Features & Advantages, Structural Strength & Safety

• 70×70mm Heavy-Duty Posts – The larger cross-section offers a more substantial visual presence and a solid grip, providing significantly greater load-bearing capacity compared to standard-sized posts.

• 3.0mm Wall Thickness – This heavy-gauge specification far exceeds the common 1.2–2.0mm thickness found in typical residential railings. It ensures exceptional bending resistance and impact strength, guaranteeing long-term durability without deformation.

• 140mm Wide Welded Base Plate – The extended 140mm width delivers a larger ground contact area, ensuring more even load distribution and superior resistance to lateral forces. This makes it especially suitable for long-span railings or locations requiring additional reinforcement. The base plate is factory-pre-welded to the post for maximum rigidity and reliability—on-site installation is as simple as positioning and screw fixing, dramatically improving construction efficiency.

• 120×30mm Handrail – Offers a balanced grip profile while maintaining visual harmony with the 70mm posts, blending comfort and aesthetics.

Aesthetics & Detail Design

• Decorative Caps – Neatly conceal all screw holes on the base plate, leaving the floor contact area clean and seamless. The result is a refined, high-end appearance with added protection against dust and moisture.

• Bold Visual Impact – The 70mm posts combined with 140mm wide bases create a strong, clean-lined aesthetic that suits modern minimalist, industrial, and neo-Chinese interior styles that emphasize texture and substance.

• Enhanced Span Control – The robust post-and-base combination significantly reduces swaying and vibration, ensuring rock-solid stability even over extended spans.

Installation Convenience

• With pre-welded base plates and ready-to-install decorative caps, the system requires only three simple on-site steps: positioning, drilling, and screw fastening. No complex assembly is needed, which shortens installation time and lowers labor costs.

Typical Applications

• Premium Residences – Villas, penthouses, duplexes – ideal for both interior staircases and elevated balconies.

• Commercial Spaces – Hotel lobbies, shopping mall atriums, exhibition halls – where aesthetics and safety are equally critical.

• Public Facilities – Schools, hospitals, subway stations, footbridges – high-traffic areas that demand enhanced protection.

• Outdoor Areas – Terraces, gardens, rooftop decks – where the wide base plate provides superior wind resistance and stability.
