China KAVASS Stainless Steel In-Ground Telescopic Bollard – Hidden Installation | Height Adjustable | Premium Security Products, Factories

When security must be invisible until it’s needed, this in-ground telescopic bollard delivers silent authority without compromising design. Fully recessed into the pavement when not in use, it leaves only a seamless stainless steel cover at surface level—ideal for high-end plazas, government entrances, and private estates where clean lines and controlled access go hand in hand.

  • Vanishes into the ground – When lowered, only a flush stainless steel cover remains, preserving clean pavement lines and pedestrian safety.
  • Rises on command – A single key turn lifts the post to full height; no power, no noise, just reliable mechanical action.
  • Built for decades, not seasons – Seamless 304/316 stainless steel with brushed finish resists salt, rain, and urban grime without rust or fading.
  • No exposed parts, no weak points – The lock and mechanism are fully enclosed, shielded from tampering, vandalism, and weather.
  • Architect-friendly design – Zero above-ground hardware when retracted—ideal for plazas, lobbies, and heritage sites where aesthetics matter.
  • Made for your project, not just your specs – Customize height (600–1200mm), add laser-etched logos, or match existing finishes via OEM/ODM.
  • Factory-direct quality & timeline – As the original manufacturer, we deliver fully tested units in 30 days, anywhere in the world.

Frequently Asked Questions (FAQ)
Q What are the primary materials used for these manual telescopic bollards?
These manual telescopic bollards are manufactured using high-grade Stainless Steel (available in 304SS and 316SS grade options) or heavy-duty Carbon Steel (defaulted to premium Q235 steel) to ensure long-lasting durability and impact resistance.
Q What finishes are applied to the carbon steel and stainless steel options?
For carbon steel bollards, the standard finish is hot-dip galvanizing or E-coated combined with a tough powder coating. Stainless steel bollards feature a sleek, modern satin polished finish for maximum corrosion resistance.

Depending on the chosen model and your security requirements, we offer telescopic bollards with integrated security Key Locks or Oval Locks for convenient manual operation.

The required depth underground varies based on the height of the bollard. Underground depths range from 705mm (for a 500mm high bollard) up to 1128mm (for a 900mm high bollard) to guarantee stable, solid foundation support.
Q What wall thickness options do you offer?
Our standard manual telescopic bollard models feature a robust wall thickness of 3mm, providing an optimal balance of structural strength and ease of manual lifting.
