These barriers are blow moulded.That means that they are inflated as a hot, hollow thermoplastic preform inside of a closed mould. This means that the inflated shape takes on the form of the mould cavity. This provides consistency, meaning that each of the plastic barriers are manufactured to exactly the same specification and reduces the risk of quality issues
2, Barriers' high visibility colours act as an early warning of hazards for both pedestrians and road users, with an additional reflective strip to enhance visibility after dark or in poor weather conditions.
