Artificial turf specifications explained
A data sheet can describe a product, but one impressive number cannot prove that the complete system is durable, comfortable, safe, drainable, or appropriate for a particular yard.
The complete system, top to bottom
The visible fibre system
| Term | What it measures | What it does not prove |
|---|---|---|
| Pile height | Distance from backing to fibre tip, usually in millimetres. | Resilience, density, comfort, durability, or suitability by itself. |
| Gauge | Spacing between rows of tufting, often stated as a fraction of an inch. | How many stitches, fibres, or grams of yarn are present. |
| Stitch rate | Tufts or stitches over a stated length; the denominator must be shown. | Total density unless gauge, tuft construction, and yarn count are also known. |
| Face weight | Mass of pile yarn above the backing per unit area; confirm whether that definition is used. | Total product weight, fibre quality, or system durability. |
| Dtex / denier | Linear mass of yarn: dtex is grams per 10,000 m; denier is grams per 9,000 m. | Performance without the filament count, polymer, profile, and construction. |
Polymer and yarn design
Landscape fibres are commonly polyethylene, polypropylene, or combinations. Polyethylene is often selected for softer upright fibres; polypropylene may appear in thatch or other components. Polymer name alone is not a grade. Resin formulation, pigments, UV stabilizers, additives, filament geometry, thickness, processing, and quality control all influence performance.
Yarn profiles may be flat, C-shaped, S-shaped, W-shaped, diamond, ribbed, or otherwise engineered. Shape can influence feel, reflection, split resistance, and recovery, but marketing names are not a standardized ranking. Ask for a physical sample, ageing evidence, and a completed application similar to the proposed use.
Tufting and backing
Fibres are tufted into a primary backing, then secured by a secondary coating or backing system. Product documents may mention latex, polyurethane, hot-melt, woven components, coatings, or composite structures. Important questions include tuft bind before and after ageing, dimensional stability, water exposure, seam compatibility, temperature limits, and whether the backing is perforated or designed for broad-area flow.
Density calculations require definitions
“Blade count,” “tuft density,” “stitch density,” and “fibre density” may be calculated differently. A tuft can contain multiple yarn ends and each yarn may contain multiple filaments. Require the formula, area unit, and construction assumptions before comparing suppliers. Convert every proposal to the same units and do not compare a tuft count from one sheet with a filament count from another.
Technical properties worth requesting
- Exact product code, manufacturing location, production date or batch traceability, colour, roll dimensions, and tolerances.
- Polymer and filament construction for primary fibre and thatch.
- Pile height, gauge, stitch rate with denominator, face weight definition, total mass, and tolerances.
- Backing construction, coating, tuft bind, seam/adhesive compatibility, and perforation or flow design.
- Dimensional stability, tensile properties, UV/weathering protocol, colour change, fibre wear/splitting, and temperature limits.
- Permeability test method and sample condition—not just a volume claim.
- Applicable chemical-content tests, laboratory, date, detection limits, pass criteria, and exact SKU sampled.
- Installation, infill, maintenance, warranty, and end-of-life instructions.
How to compare two products
- Confirm both data sheets describe current production and the exact offered SKU.
- Normalize units, definitions, and test editions.
- Separate product properties from installed-system performance.
- Identify missing values instead of assuming they are average or equivalent.
- Prioritize the use case: pet hygiene, wear, appearance, softness, heat, drainage, play, or putting performance.
- Verify that the proposed base, infill, seams, edges, and care preserve the claimed product performance.
Technical references and scope
Sports programmes provide useful test vocabulary but do not certify a residential lawn. FIFA’s programme evaluates complete football systems in laboratory and field conditions. ASTM lists separate methods for properties such as turf-system permeability, impact, abrasiveness, lead, metals, and PAHs; applicability depends on the use and current edition.
