structured or flat? You decide…

‘Blade profile’ refers to the shape of the yarn extrusion that makes each blade of artificial grass

A number of blades with different profiles are grouped together and looped through the backing material to make a tuft.  Tufts are created in rows which in turn, side by side make artificial grass.

When looking at blade profiles the key blades to look at are the ones that make up the main body of the grass.  The tall blades that are most frequent in the product.

Blade profiles fall into two different categories – flat or structured.  There is usually also a curly yarn in the product but this will be a flat profile that has been mechanically altered.  A flat blade profile means exactly that – the blade is simply a flat extrusion of plastic.  Structured blade profiles however come in a number of different shapes and they are often signified by a letter – so for example a ‘c’ profile blade is shaped like a ‘c’ down the length of the blade, a ‘v’ profile is shaped like a ‘v’ and so on.

The blade profile is very important in the durability, feel and lifespan of your artificial grass.  A blade profile with structure will create a denser feeling product with better vertical memory and ultimately it will age better.  Its importance is neatly symbolised in the example of a strip of paper; if you take long thin strip of paper and hold it vertically in one hand it will fall over.  If you give that paper structure, i.e. by folding it in the middle or curving it into a ‘c’ shape you give the paper the ability to support itself.

This example directly transfers into artificial grass and one of the first indicators of the quality of an artificial grass product is its ability to stand up after being unrolled for the first time.  A good quality structured profile will stand up quicker.  A bad quality unstructured blade profile won’t stand up at all without assistance (brushing etc.)

All manufacturers should be using structured blade profiles – the science speaks for itself.  The reality is that many don’t and this is for a number of reasons; structured blades cost more to produce; many of the profiles such as ‘c’ and ‘v’ are patent protected so can only be used by the company that owns the patent; mass procurement of yarn materials meaning manufacturers are sat on stock piles which they need to use before they can update their product.

Do your own test and line a flat profiled product sample next to a structured profile sample where your door matt usually is or under your desk for a few weeks and you will see the benefits.

It’s worth noting that a structured blade profile product will feel stiffer when new.  This isn’t a bad thing in a product that you are expecting to take 15 / 20 years of repeated use and abuse.  Products soon soften up with use and with warmer weather.

How to do a side by side comparison of blade profiles

Start by taking a single tuft out of each of the grass products you want to compare.  A tuft comprises of a number of individual yarn ends (blades) grouped together and tufted through the latex backing and back out again to give the appearance of two clumps of grass. To do this you will need to press a knife blade underneath the centre of the tuft on the back of the grass as shown in the picture below and gently pry the tuft loosely from its latex backing.  Then with your fingers pull the tuft free from the backing. This should be fairly easy to do.

Looking at the tuft – you will be able to see that there will be a combination of different types of yarn. In most good products there will be a combination of flat, structured and curly blade profiles.  A better product will usually have more structured blade profiles and less flat ones.

It’s as simple as that.

The Turf King urf™ range (2015 range) has been built using a ‘y’ profile.  We developed this profile to give greater structure and vertical memory than a ‘c’ or ‘v’ profile could give.

2017 – TurfWorks Sensation has been developed with a ‘propeller’ yarn which is shaped like a lazy ‘s’ giving the extrusion great vertical strength whilst allowing it to remain soft to touch.

Top Turfing Tip | test your blade profiles

A great way to test the resilience of an artificial grass product (which usually indicates good material quality, good structure or both) is to place a sample in a high traffic location and see how it performs.  Replace your door mat for a couple of months, car mats, penalty spot, chipping mat with an artificial grass sample and you’ll soon get an idea of its capability.
