Commercial Artificial Turf Specifications: An Architect’s Guide

An architect opening a turf submittal often finds three supplier sheets that describe the same square metre with three different numbers. The pile height, face weight, and backing method rarely line up, and the gap between two quotes can look like a quality gap when it is really a spec gap. The fix is to read the specification the way a manufacturer reads it: fibre, density, backing, and roll format decide everything that follows on site.

Commercial artificial turf specifications turn a roll of fibres into a measurable build. Our own line runs every batch through the same compounding, tufting, and coating sequence. The numbers on the sheet then map to a physical product you can verify before the container ships.

Pile Height Sets The Look And Use

Pile height is the distance from the backing to the blade tip, measured in millimetres. Commercial artificial turf specifications always open with pile height, because it is the line a client sees first. Commercial landscape turf runs 20 to 45 millimetres, while sports turf often reaches 40 to 60. A rooftop terrace at 25 millimetres reads as a tidy lawn; a municipal play area at 35 millimetres hides wear in the busy lanes. Spec the wrong height and the surface looks thin within a single season, which is the fastest way to lose a client sign-off.

Start every commercial brief at 30 millimetres unless the use case pushes lower or higher. For lower-traffic landscape grades, the residential artificial grass range shows where a shorter pile still reads well. For field heights above 40 millimetres, the sports artificial grass range is the better reference point.

Face Weight Drives Wear And Lifespan

Face weight is the mass of yarn per square metre, given in grams per square metre or ounces per square yard. On commercial artificial turf specifications, face weight is the second line after pile height and the one that predicts lifespan. Higher face weight means a denser turf that wears more slowly under foot traffic. Commercial landscape grades sit around 1,500 to 2,800 g/m²; heavy-traffic sports grades exceed 3,000 g/m². A distributor quoting 1,800 g/m² for a school corridor is quoting a surface that will bald in the walk lanes within two years.

Read face weight beside the traffic class, not on its own. The table below maps a typical band to the job it survives.

Stitch Rate Tuft Bind And Backing

Stitch rate counts tufts per metre and tuft bind measures the pull-out force in newtons. A rate of 150 to 300 stitches per metre with tuft bind above 30 N keeps blades upright under constant foot traffic. These two lines are the quiet proof that a roll will hold its shape through a busy season rather than splaying open at the seams.

The backing is the line specifiers forget. Relyir runs PP+Net and PU backings; the artificial turf industry treats PU as the more stable choice for wide commercial rolls because it resists water and edge curl. Skip the backing line on the sheet and a 5m-wide field roll will curl at the edges the moment the sun hits it.

Roll Width Controls Seam Count

Our plant ships rolls in three widths: 2m, 4m, and 5m, each 25m long. Commercial artificial turf specifications should name the roll width explicitly, because the drawing and the quote must agree on it. The width you choose sets how many seams land on the finished floor, and seams are the first place a commercial install fails. A 2m roll is the cheapest to ship and the easiest for two workers to handle on a tight landscape bed. A 4m roll covers most courtyards with fewer joins, while a 5m roll suits sports fields where every seam is a future failure line.

Width also touches budget directly. The pricing logic behind each format is laid out in the artificial grass cost per m2 factors guide. Read it before you fix the roll size on a drawing.

Drainage Keeps Commercial Fields Playable

Drainage rate is measured in litres per square metre per hour, and it decides whether a flat roof or a sports field is usable the morning after a storm. A complete set of commercial artificial turf specifications also lists the drainage rate, because a flooded field closes the same day it opens. Perforated backing supports 20 to 60 L/m²/h, enough to clear standing water before a school bell or a booked match. A facility that floods for a day loses booking revenue that no cheap roll can win back.

The drainage line is also the line most often dropped from a budget submittal. Keep it on the sheet, match it to your local rainfall, and the surface stays open for play instead of closing for drying. The spec you write is what prevents the downtime, not the colour of the grass.

How We Build The Roll End To End

Our plant turns raw polymer into a finished roll across eight steps: compounding, extruding, twisting, tufting, coating, drying, perforating, and rolling up. Each step is where one spec line is born. Tufting sets the stitch rate, coating sets the backing, and perforating sets the drainage holes you read as a rate on the sheet.

Reading the build this way changes how you treat a supplier quote. A number on the page is not a promise until it traces back to a step on the line. That traceability is the real difference between a trading company’s sheet and a manufacturer’s, and it is why we show the process instead of hiding it.

Infill And Shock Pad Make The System

For sports and playground work the roll alone is not the system. Infill, usually sand, rubber, or TPE, sits in the pile to hold blades upright and spread load. A shock pad laid under the roll sets the critical fall height for a play area. Spec both, or the surface fails the safety and bounce checks that a municipality or school will run before sign-off.

This is where a landscape specification and a sports specification split. A courtyard wants a clean roll with light infill; a field wants a full system with measured infill depth and a certified pad. The artificial grass gym turf range shows how the same roll logic scales into indoor training surfaces.

Free Samples Verify The Spec Sheet

The cheapest verification is a sample in your hand. We send free 20x20cm cuts; the buyer covers freight, and DHL or FedEx delivers in 4 to 6 days to most regions. Customized sample production adds 10 to 15 days if you need a specific pile or colour matched to the drawing.

Run a five-point check on every cut before you write the acceptance note:

Measure pile height with a caliper and confirm it matches the sheet. Weigh the cut for face weight, or send it to a lab if the number is contested. Bend the backing to tell PU from PP+Net by feel and memory. Confirm the roll width printed on the label. Lay the cut under your site light to judge colour against the approved swatch.

Order the cuts through the free-samples page and keep the measured numbers next to the supplier sheet. The sample that matches the sheet is the roll you should buy.

Specifying The Right Turf For Your Build

The right commercial artificial turf specification is the one that matches traffic, not the one with the biggest numbers. Treat commercial artificial turf specifications as a linked set, not a shopping list of big numbers. A quiet rooftop terrace needs a short pile and a light face weight; a school field needs height, density, infill, and a pad. Write the spec from the use case outward, and the install stays within budget while still passing inspection.

If the brief is still open, send the drawings and the traffic estimate to the factory and ask for a matched recommendation before you close the submittal. A short consultation at the spec stage prevents the expensive change order at the install stage.

We build commercial turf as a manufacturer, not as a trader, so the specification you write is the specification we make.
