Which cone height fits which job
A plastic traffic cone manufacturer sells three specifications together, and price only makes sense once all three are fixed: height, base weight and retroreflective grade. The 300 mm cone is a car-park and driveway marker. The 450 to 500 mm cone suits school zones and private roads. The 750 mm cone is the general construction standard, and the 1,000 mm cone with a weighted base is what live carriageways and night work call for. Choosing by height alone is the most common sourcing error in this category.
PVC versus PE bodies, and what sits underneath
Most pvc traffic cone bodies are moulded in flexible PVC so the cone flexes and rights itself when a tyre clips it instead of cracking. PE versions, in LDPE or HDPE, offer an alternative resin route and are common on export programmes that standardise on polyolefins. Underneath, the base decides whether the line survives the shift: a thin one-piece plastic base suits indoor aisles, while a recycled-rubber weighted base drops the centre of gravity and keeps a 1,000 mm cone planted through truck wake and wind. Expect roughly 1.0 kg at 300 mm, 2.0 to 2.5 kg at 500 to 750 mm and 4.5 to 5.5 kg for a weighted base cone at 1,000 mm.
Retroreflective grades that pass inspection
A reflective road cone earns its keep after dark, and inspectors check the sleeve before anything else. Class 1 engineering-grade tape returns less light and suits car parks and low-speed private sites; Class 2 prismatic high-intensity sleeving is the expectation on live carriageways and night closures, and collar width grows with the cone: about 10 cm on a 300 mm cone, 25 cm at 750 mm and 32 cm at 1,000 mm. European programmes reference EN 13422 for cones and delineator posts, while US buyers work to MUTCD practice; ask which standard the quotation is written against.
What to confirm with a plastic traffic cone manufacturer
- The full trio in writing: height, gross weight and reflective class, not heavy duty adjectives.
- Body resin and base material, since flexible PVC, PE and rubber-base constructions behave differently in heat and cold.
- UV stability and colour retention for outdoor programmes, plus a stacking test after shelf storage.
- Logo or message printing on the collar, and whether the print sits above or below the reflective band.
- Packing method, typically woven bags, and pieces per container for freight comparison.
Traffic safety cone programmes usually pair cones with delineator posts and barrier systems, so confirm the full work-zone list before ordering. Compare capability in the plastic products catalogue, then shortlist through the company directory. Our guides on reading a plastic datasheet and third party inspection cover the verification steps that keep a cheap cone from becoming an expensive one.
