Поле 3G vs 4G: в чём разница?

Это поле 4G просто поле 3G без резиновой крошки? Покупатели задают нам именно этот вопрос каждую неделю, и ответ: нет. Поле 3G — это система с наполнителем, спроектированная как трава плюс песок плюс резина; поле 4G — концепция без наполнителя, где устойчивость должна обеспечиваться исключительно ковром. Именно это отличие определяет испытания, обслуживание, бюджет и то, что ваше покрытие допущено принимать.

Мы отвечаем на вопрос о выборе между 3G и 4G с производственного пола, где оба варианта фигурируют в одних и тех же запросах на ценовое предложение каждую неделю. Раздел 2G, включая жёсткое слово о маркетинге поколений, — в нашем руководстве по искусственной траве 2G и 3G. На этой странице мы углубляемся в утверждения о 4G: как работает каждая конструкция, для чего каждая может быть протестирована и одобрена и во сколько обходится владение каждой. Там, где доказательная база слаба, мы это говорим; там, где утверждение — маркетинг, мы называем это маркетингом.

Что такое поле 3G?

Поле 3G — это трёхкомпонентное покрытие из искусственной травы: ковёр с длинным ворсом, кварцевый песок и резиновый функциональный наполнитель. В футбольных конструкциях длина ворса обычно составляет 40–60 мм, при этом песок оседает у основания ворса, а резина заполняет большую часть пространства над ним. Амортизационная подложка под ковром является опциональной и назначается при необходимости дополнительного смягчения. Покупатели до сих пор называют любое искусственное покрытие «Астротурфом», но современное поле 3G не имеет ничего общего с теми старыми коврами с коротким ворсом, кроме семейного прозвища.

Наполнитель выполняет сразу три функции. Он держит ворс в вертикальном положении, стабилизирует ковёр и обеспечивает основную часть амортизации. Именно поэтому скольжение на правильно заполненном покрытии 3G менее травматично, а мяч ведёт себя ближе к естественной траве. Большинство футбольных конструкций сочетают монофильные ворсинки из полиэтилена с подстилкой из полипропилена — комбинацией нитей, которая хорошо известна производственной стороне рынка. Один из спортивных органов описывает такие поля как прочные, безопасные покрытия круглогодичного использования, способные выдерживать интенсивную нагрузку при любой погоде.

Что такое поле 4G?

Поле 4G позиционируется как шаг, при котором наполнитель исключается. Вместо песка и резины покрытие опирается на структуру нитей, плотность и конструкцию ковра, чтобы удерживать ворс вертикально и амортизировать нагрузку. На практике эта маркировка охватывает несколько конструкций, что является первым тревожным сигналом: когда одно слово описывает множество продуктов, это слово — маркетинг, а не спецификация.

Без наполнителя именно плотность выполняет ту работу, которую в других системах выполняют песок и резина: она удерживает ворс вертикально и поглощает ударные нагрузки. Компромисс — более чистое покрытие без свободной крошки, которая могла бы мигрировать, именно поэтому ковёр без наполнителя впервые нашёл реальное применение в закрытых залах и на небольших тренировочных площадках. Стоит также ожидать, что маркировка будет продолжать смещаться, потому что каждый производитель решает вопрос плотности по-разному.

Бок о бок: полное сравнение

Разместите две системы рядом, и различия перестанут быть просто прилагательными. Это сравнение полей 3G и 4G, которое мы проводим вместе с покупателями перед подписанием любого коммерческого предложения на укладку искусственной травы.

One analogy holds the table together. Infill works like ballast in a ship’s hull: invisible while it sits where it should, and the first suspect the moment the surface starts to misbehave. Remove the ballast and the whole design has to compensate with structure alone. That is precisely the bet a 4G build makes.

Ball behaviour splits the two systems too. On a filled 3G surface the bounce and roll stay predictable because the infill damps the impact. On non-infill carpet, players report a quicker roll and a higher bounce that varies between products, which matters once matches depend on a true bounce.

On either system, roll width quietly moves the final bill. Our standard rolls come in 2m, 4m or 5m widths at 25m long, and a 4m roll covers roughly 100 square meters. On pitch-scale projects the wider carpet means fewer seams to tape and protect, which matters most where infill would migrate through a bad seam. The range view of surfaces sits on our sports artificial grass hub.

Ощущения игрока: отскок, сцепление и нагрузка на кожу

Construction settles the comparison on paper; players settle it with their feet. Grip is where the 3g vs 4g pitch difference starts. On a filled surface, studs bite into sand and rubber, so turns, stops and sprints feel controlled. On dense non-infill carpet, grip comes from the yarn alone, and the firmer ride makes play feel quicker. Neither system is wrong here; they simply hand the same game a different tempo.

Skin tells the rest of the story. A slide on a properly filled 3G pitch lands on a cushioned layer, so friction stays predictable and abrasions stay shallow. A surface without that layer leans entirely on the shock pad beneath it, so comfort varies more from build to build. That is why pad and infill specification decide how a surface feels as much as the carpet does. Facilities that host mixed ages feel this most, because children judge a surface by how falls end.

Safety questions belong in the same conversation, handled honestly. Published research on infilled 3G surfaces has generally found injury rates comparable to natural grass, which is why the established route survived years of scrutiny. No comparable body of long-term evidence exists yet for non-infill play, and until it does, any safety claim either way is a forecast, not a finding.

Для каких видов спорта и уровней подходит каждое

Match the surface to the sport before comparing labels. Football runs the full span on 3G: junior training, senior sessions and sanctioned competition all sit inside the tested route. Rugby asks more of a surface, because scrums and repeated heavy contact demand deeper shock absorption and stricter testing, and only an infilled system built for that load qualifies.

Hockey sits on a different branch of the family, historically tied to shorter sand-dressed carpet rather than long-pile 3G. Multi-use games areas compromise with shorter piles and sand dressings, which is why a MUGA never plays like a full-size football pitch. The lesson generalises: a surface tuned to one sport rarely serves another at the same standard.

Training grounds sit lower down the same ladder. A session surface can tolerate compromise on pile height and testing because nobody awards points on it, but write the intended level into the quote anyway. A pitch specced for drills will feel the strain the moment fixtures arrive.

Schools and community clubs weigh a different set of numbers: weekly hours, mixed age groups and a maintenance budget that competes with everything else. A 3G artificial turf installation earns its keep where the site hosts fixtures or rents out peak hours. Non-infill carpet suits a low-mess training yard that never hosts a league game. The 3g vs 4g pitch choice here is a timetable question, not a technology question.

Правда о маркировках 4G и 5G

Independent definitions are blunt about this. Guidance published by one national football association states plainly that there is no such thing as 4G or 5G, calling them terms used by salespeople. The same guidance declines to accept non-infilled carpets as football surfaces at the levels that matter. Government guidance in another market goes further, classifying 4G as an early-stage technology that no governing body has yet recognised.

None of this makes non-infill carpet useless. It makes it a different product with a narrower job: training areas, indoor facilities and recreational spaces where loose infill is a nuisance. Our advice is to treat every 4G quote as an unproven system until the test reports arrive. Ask what the carpet is made of, how density is achieved and which tests the finished system has passed.

The 5G label now drifting through brochures deserves the same scepticism. A bigger number is a sales story until an independent test category stands behind it, and today none does.

Болты: что надевать на каждый тип покрытия

Footwear is where the 3g vs 4g pitch difference becomes personal. On an infilled 3G surface, moulded studs and artificial-ground soles are the sensible default, because they grip the carpet without punching through the pile into the base. Long aggressive studs and metal blades dig past the fibres, stress the backing, and most facility operators ban them for exactly that reason. Facility rules exist to protect both the player and the carpet, so check them before the first session.

Non-infill carpet plays firmer underfoot, and short stud patterns keep that ride honest. Smooth trainers rarely give enough grip once play speeds up. The same pair of boots usually serves both surfaces, which is one less line item to budget. Because every 4G build differs, the operator’s footwear rules are the final word on any given site.

Погода: заморозки, наводнения и сильные дожди

Rain is the easy case when the system is built right. An artificial turf installation drains through perforated backing into a free-draining base, and the falls engineered into that base move water off the field. When a surface holds water, the fault usually sits below the carpet: a blocked or badly graded base, not the turf itself.

Freeze is the honest caveat. Moisture held inside sand and rubber infill can harden in a cold snap, and a frozen 3G surface is unsafe until it thaws. That is why responsible operators inspect and close rather than schedule. A thaw returns the surface to service, and the inspection record is what protects players in between. Neither system escapes that rule, because both stand on the same kind of base.

Non-infill carpet does not automatically handle standing water better. With no infill in the pile, a 4G pitch leans entirely on base drainage and fibre design. A seller who equates no infill with all-weather performance is skipping a step. Judge weather behaviour by the drainage plan, never by the generation label.

Обслуживание, на которое нужно закладывать бюджет

A caretaker dragging a grooming brush across goalmouths every Friday knows the difference better than any brochure. A 3G artificial turf installation lives on that routine: grooming keeps the blades upright, top-ups replace rubber that play has migrated, and periodic de-compaction stops the surface hardening. Skip the cycle and ball roll degrades first, then player complaints arrive.

Maintenance is where the 3g vs 4g pitch argument is usually won. The 4G column looks emptier, and sellers lean on that. What never disappears is brushing, cleaning and inspection, because litter, organic debris and compaction happen on any outdoor carpet. No infill does not mean no maintenance, and a supplier who says otherwise is selling the quote, not the surface.

Стоимость за весь срок службы: десятилетний взгляд

Follow the money across ten years, not one invoice. A 3G budget carries three infill line items: the initial sand and rubber purchase, periodic top-ups as play migrates material, and de-compaction visits. A 4G budget deletes those three items but rarely prices the compensation: denser carpet, heavier yarn and a firmer ride for players who judge the surface every session.

Longevity under heavy usage is where the systems part company again. A maintained 3G build absorbs thousands of hours of school sessions, club training and weekend fixtures, and wear shows first in goalmouths and centre circles where play concentrates. Non-infill carpet is marketed as outlasting infilled systems, yet with long-term data still missing the claim remains a forecast. A shallow infill profile can concentrate wear in exactly those high-traffic zones. On either carpet, the care programme decides service life more than the label does.

Public data on the full lifetime comparison is thin, and we would rather admit that than invent a winner. What is documented is narrower: non-infill builds save the infill purchase and its follow-up costs. The service life of a maintained 3G pitch tracks usage, climate and how faithfully the care programme is followed. Our factory-direct carpet pricing runs $7-60 per square meter, indicative until spec and quantity are confirmed, with grade and type setting the final point. Compare systems on carpet spec, maintenance plan and test evidence together, never on the carpet line alone.

Получение допуска к лиговым матчам

This is where the 3G vs 4G pitch difference stops being academic. Major governing bodies run established laboratory and field test programmes for infilled 3G systems, and an artificial turf installation that passes can host training and specified levels of competitive play. Non-infill systems have no dedicated certification category today, so a 4G surface cannot currently carry the approval a sanctioned fixture requires.

The bill for ignoring this arrives at fixture time. A club that needs sanctioned fixtures must budget for the tested route from day one, because no retrofit turns non-infill carpet into an approved surface. Buying the unproven system for league play usually means buying the compliant surface twice.

Как бы мы его спроектировали

If a client brought us both quotes for an artificial turf installation tomorrow, we would put three questions on the table first. What sport and what level does the timetable serve? What maintenance crew and budget will actually exist in year three? Only then: what does each carpet cost per square meter? The answers sort 3G from 4G faster than any generation number.

From the production side, we spec the carpet first and let labels fall where they may. A football build starts at the yarn: polyethylene blades, a PP thatch underneath, then a PP and net backing, adding PU coating only where the site demands extra hold. Every spec ships with its test reports attached, because the paperwork is part of the product.

Мы отгружаем эти системы напрямую с завода и предпочитаем отправлять образцы вместо слоганов. Закажите образцы 20 x 20 см, протестируйте их со своими полевыми игроками и не привязывайтесь к маркировке поколения. Правильным будет то покрытие, которое вы можете протестировать, обслуживать и себе позволить.
