The plastic seats available in this section are offered in three main types: backless, medium back, and high back. All models are made of polypropylene and feature a solid support structure with additional ribbed reinforcements under the seat. The double back wall significantly increases the resistance of the seats to acts of vandalism. The seats are resistant to low and high temperatures and to UV radiation. They all have a recess for attaching a number plate and a hole through which water is drained.
