When are smooth deck boards better than castellated? How do you know which suits your project best? It’s easy to make a traditional choice of castellated timber decking for your project.

Here is a guide to the characteristics of smooth deck boards to help you make the right choice for your project.

Smooth profile allows for further accessibility and comfort

Smooth deck boards can provide a more even surface, to aid ease of travel across the deck area. This is particularly beneficial for wheelchair users, pushchairs and bicycles providing a smoother surface to travel over. Deck boards with a smooth profile provide greater walking comfort for high heel wearers who often find grooved boards problematic.

Less abrasive grit

A less abrasive grit provides less resistance than a standard anti-slip insert, whilst still exceeding the HSL minimum requirement, and so makes for an easier walking surface, this is beneficial for the less able and areas with high pedestrian traffic.

Easy to clean

Smooth decking is frequently specified for outdoor urban areas where people congregate, food is served or hygiene is of high priority. Smooth boards prevent food, dirt or litter becoming trapped, making it much easier to clean and removing any further slip risk from trapped debris.

Coloured anti slip inserts

Coloured anti slip inserts can be used for aesthetic purposes such as decking for schools or hospitals or to help with inclusivity. For the visually impaired coloured inserts or wider anti slip strips can be used to indicate stairs or changes in level such as doorways, steps and ramp entrances.

Smooth boards naturally create a more even, natural looking landscape. They also have several significant practical advantages over grooved boards for particular applications such as:

  • Schools and universities
  • Retail and office developments
  • Bars and restaurants
  • Stadiums and tourist attractions
