Golf turf terms, defined
Short, plain-language definitions of the terms used across this site — one paragraph per term, with a figure or unit where one applies.
Infill
The loose material, usually sand or rubber granulate, packed between the fibres of an artificial turf system. MC Turf Systems' products are built without infill: the pile itself carries the ball and the foot.
Pile height
The height of the turf fibre above its backing, measured in millimetres. It ranges from 13 mm on a chipping green to 30 mm on a driving range mat or tee line — the shorter the pile, the faster and truer the roll.
Filaments per m²
The density of fibres per square metre of turf. A higher filament count gives a firmer stance and more resistance to wear; references on this site range from roughly 650,000 to over 1.4 million filaments per m².
Stimp
The industry measure for putting-green speed, expressed as the distance the ball rolls on a level surface. It lets two greens — real or artificial — be compared on the same scale.
Cross-over vs. straight production
Two ways of weaving the turf backing. Cross-over production interlocks the yarns for extra pile stability under repeated impact, used for driving range mats and tee lines; straight production keeps the yarns parallel, typical for borders and green surrounds.
PU coating vs. SBR coating
The backing applied under the turf to lock the fibres in place. PU (polyurethane) coating is lighter and more UV-stable; SBR (styrene-butadiene rubber) coating is heavier and more cost-effective. The choice affects both lifespan and price class.
PP / PA / PE
The three fibre materials used across the range: polypropylene (PP), polyamide — nylon — (PA) and polyethylene (PE). PA is the most wear-resistant and is reserved for putting, chipping and pitching greens; PP and PE balance cost and durability for higher-volume applications.
Ex mill / ex factory Belgium
A price quoted at the point the product leaves the factory in Belgium, before transport and installation are added. It is how per-square-metre prices in this industry are usually expressed.
Geosynthetic bunker
A bunker lined with a geosynthetic fabric rather than left as bare sand on soil. The liner keeps sand and subsoil separate, so the bunker drains evenly and holds its shape after heavy rain.
Lake border
The turf lining installed along the edge of a water hazard, finishing the transition between bank and water without erosion of the surrounding turf or soil.
Wedging
Short-game practice within roughly 70 metres of the green — wedge shots, chipping and pitching. More than 60% of shots played in a round of golf fall inside this range, which is why it gets its own practice product line.

Every product page states pile height, filament count and coating for its own reference.
