Frequently Asked Questions (FAQ)
What is the standard material used for these fixed bollards?
Our heavy-duty model (KVS-M30-FB) is constructed from high-strength Q345 steel. Other related fixed bollards are manufactured using standard Q235 carbon steel, 304 stainless steel (304SS), or 316 stainless steel (316SS) based on your installation requirements.
What anti-collision rating do these fixed bollards offer?
The KVS-M30-FB model features a certified K4 anti-collision class rating. With a wall thickness of 20mm, a diameter of 273mm, and an inground depth structure, it provides high-impact resistance for security-sensitive sites.
What surface finishes are available for carbon steel and stainless steel bollards?
For carbon steel bollards, the default finish options are hot-dip galvanizing or E-coating combined with a durable powder coating. Stainless steel bollards are finished with a clean, modern satin polishing.
What choices do I have for the top head design of the bollards?
Our in-ground fixed bollards come with three primary head styling options: Flat head, Dome head, or Beveled head, allowing you to match the visual aesthetic of your surrounding architecture.
Can these bollards be installed in environments with high moisture?
Yes. Due to the high-grade materials like 304SS/316SS and the protective hot-dip galvanized finish on carbon steel variants, these bollards offer exceptional corrosion and rust resistance, making them ideal for outdoor and wet climates.
