When a vehicle jumps the curb, your bollards are the only thing that argues back.

Start with one question: how often does a vehicle need to pass that spot? Never → a fixed bollard. Sometimes (deliveries, fire lane) → a removable bollard you lift out and lock back. Daily → a retractable bollard you drop and raise in seconds. Then pick the material for your environment (steel indoors/dry, stainless for coastal or washdown).

Carbon steel (Q235) in a safety-yellow powder coat gives you the most strength per dollar and is ideal for dry, indoor, and most outdoor sites. Choose stainless — an SS304 post with a corrosion-resistant SS316 sleeve — for coastal air, frequent washdowns, food-grade areas, or anywhere a polished, high-visibility look matters.

Yes. A 6″ post carries more mass and wall than a 4″, so it resists heavier impacts — a common pick for truck traffic and high-risk corners. A 4″ post is lighter, lower-cost, and fits tighter spaces and lighter-duty spots. Both come standard at 36″ above grade.

A properly anchored steel bollard is built to resist and deter vehicle impact, and that resistance scales with diameter, wall thickness, and how it’s mounted. Note that impact performance varies by configuration; these are security and perimeter posts, not certified crash-rated barriers unless a specific rating (for example ASTM F2656 / K-rating) is called out. If you need a documented crash rating, contact us and we’ll confirm the right specification for your site.

Yes. Removable models seat into a flush in-ground sleeve and secure with a padlock, so they hold like a fixed post until an authorized person unlocks and lifts the post out for access — then locks it back afterward.

Fixed baseplate bollards anchor directly onto your existing concrete using a ⅜″ steel baseplate with pre-drilled holes and mechanical or chemical anchors. There’s no excavation, no rebar, and no waiting for a footing to cure — most installs are an afternoon job.

It depends on the type. Removable bollards use a shallower flush sleeve sized to the post. Retractable (drop-down) models use a deeper in-ground housing — about 42″ — so the post can lower fully below grade and still lock solid when raised.

Yes — over 200 powder-coat colors are available, along with multiple cap styles. Most security applications use high-visibility RAL 1023 safety yellow, and reflective strips are available on retractable models for low-light visibility.
