Artificial grass filament shape

Choose the Perfect Lawn: A Guide to Filament Shapes and Their Benefits

Approximate reading time: 4 minutes, 18 seconds

The shape of the filament in artificial turf is the outline of a fiber when viewed in cross-section. This filament shape gives the synthetic turf different properties and qualities. It can be manufactured using a single filament shape or a combination of several. This way, the advantages of all of them can be maximized. 

Why does the shape of the filament make a difference?

The shape of the fiber is one of the most determining factors in the quality, appearance, and resilience of your artificial grass. When we observe a cross-section of the fiber, we discover different geometries that directly influence how the grass will perform in your garden, terrace, or play area.

Beyond color or height, the shape of the filament determines crucial aspects such as:

  • Resistance to daily traffic.
  • Recovery capacity after being stepped on.
  • Sensation to touch.
  • Visual realism under different lighting conditions.
  • The temperature it reaches on sunny days.

In this comprehensive guide, we explain the different types of filaments available in our catalog, their specific characteristics, and which option best suits your particular needs.

Filament shapes

Choosing the right yarn shape is important for achieving artificial grass that meets both functional and aesthetic requirements. Below, we explain the main filament shapes and the qualities each one offers to synthetic turf.

Straight or Flat

Straight filament has a flat structure without a central rib. These are typically models with a low height (less than 25mm). It is the most traditional shape and is characterized by:

Advantages:

  • Extraordinarily soft to the touch.
  • Uniform and tidy appearance.
  • More affordable price.

Considerations:

  • Lower structural resistance.
  • Limited recovery after the step.
  • Ideal for low traffic areas.
  • The incidence of the sun on the filaments generates a certain brightness.

Recommended for: decorative areas, spaces with little use such as perimeter or decorative areas.

Spine

In this case, the filaments do have a central rib that provides a great balance between resistance and comfort. 

Advantages: 

  • Good recovery to the foot strike. 
  • High resistance.
  • Natural appearance.

Considerations: 

  • It has less smoothness due to the central nerve.
  • Certain glimmers may appear in sunlight.
  • They are very well-balanced models in terms of features. 

C-Shape

The “C” or concave shape refers to the curvature of the thread at its end. 

Advantages:

  • Memory effect. 
  • Wear tolerance. 

Considerations:

  • Ideal for high-traffic areas. 
  • Perfect for events, public areas or play areas. 
  • Suitable for children and pets.

S-shape

The "S" shape is characterized by the absence of a flat surface that reflects sunlight. This provides certain advantages focused on the look and physical appearance of artificial turf models. 

Advantages: 

  • Extraordinarily natural appearance . 
  • Softness to the touch and underfoot. 
  • The incidence of the sun does not generate glare. 

Considerations: 

  • Ideal for gardens, terraces and patios. 
  • It is frequently combined with other finishes to provide other characteristics to the synthetic grass.

Diamond

Diamond fibers are one of the latest innovations and are characterized by having a trapezoidal shape similar to a diamond. 

Advantages: 

  • Long lifespan of the artificial grass roll.
  • Great realism and naturalness.
  • Very soft. 

Considerations: 

  • Ideal for landscaping and playgrounds. 
  • Suitable for medium use and traffic. 

W-shape

The "W" shape is a favorite for public areas or residential projects because it has great recovery from foot traffic. 

Advantages: 

  • This shape retains less heat. 
  • Natural appearance.
  • High capacity to withstand traffic and recover the verticality of the fibers. 

Considerations: 

  • It's a pleasant surface for adults, children, and pets. 
  • Flexible and with memory effect. 
  • They are comfortable models

  • Strength. For great strength, choose C-Shape, Diamond, and W-Shape fibers.

Recovery with impact. C-Shape and W-Shape fibers are those with the greatest recovery with impact and movement.

Selection guide according to specific use

For gardens

If you're looking for a lawn for your home garden that will see moderate use, we recommend:

For children's areas

Safety and durability are priorities in areas where children play:

  • First option: Diamond or W-Shape
  • Second option: C-Shape

These filaments combine excellent recovery with low surface temperature and high wear resistance

For terraces and penthouses

In elevated spaces where aesthetics and comfort are paramount:

  • First option: S-Shape or Straight
  • Second option: Spine

Combination of different filaments

W-Shape + S-Shape

The combination of these two types of filaments creates artificial grass models with unparalleled characteristics. By taking advantage of the benefits of both types of filaments, the following is achieved: 

  • Great recovery to the gait. 
  • Soft and pleasant models to the touch and underfoot. 
  • A very natural appearance.

W-shape + Diamond

The W-shape and Diamond filament forms are two of those that provide the greatest resistance to synthetic turf. The combination of both results in: 

  • A synthetic grass with a long lifespan. 
  • Very natural appearance.
  • Good resistance and recovery from impact

W-Shape + C-Shape + Diamond

It's also possible to combine more than two filament shapes. You might not notice the different ends, but you'll benefit greatly from the advantages of your artificial grass roll. 

  • Very high recovery capacity when stepped on. 
  • High resistance to intensive use. 
  • Realistic and natural color.
