Identical data sheets can hide different factories. Three quotes for a commercial pitch carry the same pile height, gauge and backing code. Only one names the plant that tufted the yarn.
What to look for sits behind the quote. It includes the stages a supplier runs itself, the batch record behind a repeat run, and the laboratory that issued a test report. We extrude, tuft and coat on our own line.
Why Supplier Checks Decide the Project
A supplier selection for artificial turf installations goes wrong slowly. The first container matches the sample, the second is close enough, and by the third the colour has drifted.
Quote claims are checkable, and buyers seldom check them. Landscape architecture guidance records an 80% reduction in water use as common on all-weather turf fields.
The separating evidence is a set of answers: which machine ran the yarn, what the last batch label said, and who signs the claim when a seam lifts.
What to Look for in Capacity and Equipment
Capacity decides whether a supplier can carry a season of artificial turf installations without drift. Ask about the equipment, then ask to see it running.
What the Extrusion Line Tells You
Yarn quality starts upstream of the carpet. A supplier that extrudes its own yarn controls polymer grade and colour dispersion, while a buyer of yarn inherits whatever the spinner sells that month.
Tufting, Coating and Drying Capacity
Tufting sets the stitch rate, coating sets tuft bind, and drying decides whether the coating cures evenly. Ask how many machines run and how many shifts they work.
Gauge, Stitch Rate and Pile Height
Gauge is the needle spacing, stitch rate is the stitch count per metre, and pile height is the fibre above the backing. Ask for all three in writing, as published turf roll formats show.
Ask for a plant-floor video call that passes the extrusion line, the tufting heads and the coating oven in one take.
What the Supplier Makes In-House
Factories sit on a spectrum. Buyer guides group them into large branded plants with in-house yarn extrusion, medium OEM suppliers that may subcontract yarn, and small workshops with weaker documentation.
Yarn Bought In or Made On Site
The useful question is which stages belong to the supplier, not whether outsourcing exists. If the yarn is bought in, ask for the spinner’s lot reference on every batch.
Backing Built Up or Bought Finished
Backing decides how a roll drains and how well it holds a seam. Ask whether backing and tufting run in the same plant, and whether one line covers every width you order. Our own production line runs all eight stages in sequence.
One plant can quote pile, density and backing as a single custom roll specification.
Batch Consistency Across Repeat Runs
What to look for on a repeat run is drift, not one perfect first roll. Colour moves when the yarn lot changes, and tuft bind moves when the coating line runs faster.
| What Can Drift | Where a Buyer Sees It | What to Ask For |
|---|---|---|
| Yarn colour | A second pallet beside the first, in daylight | The yarn lot reference on the roll label |
| Stitch rate | Pile height underfoot and in a close-up photograph | The stitch count on the packing list |
| Coating weight | Corner lift and seam behaviour after a season | A coupon cut from the run before shipment |
| Roll identity | A roll that cannot be matched to any run | Batch number and date on every label |
Keep an offcut from the first delivery as the physical reference for the second one.
What a Sample Can and Cannot Prove
A sample proves feel, colour, fibre shape and pile height. It cannot prove batch stability, coating behaviour or how the fibre ages outdoors, because those are properties of a run and of time.
Free sample squares are usually 20 cm by 20 cm and arrive as three to four pieces, which is enough to compare two suppliers side by side. Courier freight is normally paid by the buyer.
Lay the samples on paving, not on a desk. Daylight shows colour cast, and a brushed pile shows how fast the fibre recovers.
Verifying Test Reports and Claims
For artificial turf installations, a test report records results for the sample the laboratory received. What to look for is a method, not a thick folder.
Check the Report Number With the Issuer
Start with the report number. Accreditation bodies that sign the international mutual recognition arrangement publish lists of the laboratories they accredit. Send the number to the body in the economy where the laboratory sits.
Confirm What the Laboratory Is Accredited For
A laboratory is accredited for a defined scope, not for whatever it is asked to test. If a report covers a wear test while the accreditation covers another method, the numbers stand but the assurance does not.
Public research fills some gaps: the federal research programme on tire crumb published its findings and states that the set is not a risk assessment.
Match the Sample Description to Your Spec
Compare the sample description inside the report with the roll you intend to buy. One construction does not speak for every width, pile height or colour.
Separate Test Results From Certification
A results report and a certification mark are different instruments. A marketer holding a third-party certification must still substantiate every express and implied claim.
Confirm the report date sits inside your production window, then ask what the report does not cover.
Delivery Terms That Change Landed Cost
Freight is where two identical quotes stop being identical. On artificial turf installations, the question is which port the price reaches and where risk passes to the buyer.
| Delivered To | Supplier Arranges | Buyer Takes Over From |
|---|---|---|
| Destination port | Export clearance, ocean freight, cargo insurance | Import clearance, inland haulage, unloading |
| Chinese port | Inland transport to the port, export clearance, loading | Ocean freight, insurance, import clearance |
Roll width changes the arithmetic. A 5 m by 25 m roll covers more ground per seam, while 2 m and 4 m widths travel more easily and are supplied more widely.
Handling Claims and After-Sales Response
The claim path is decided before the first order, not after the first failure. Ask who inspects a disputed roll, what evidence is needed, and how a batch number traces back to its run.
Promises of support are not response times. Ask what the claims process is and how quickly issues are resolved, then keep the answer beside the specification.
Still Buying Rolls Without Tracing the Production Line?
Identical-looking rolls hide different production lines. We build every roll to your pile, density and backing, with factory-direct pricing typically 30–50% below market prices on like-for-like specifications.
Setting Minimums and Planning Roll Widths
For artificial turf installations, minimums usually follow the roll rather than the square metre. A plant setting up a run for a colour or a pile height wants a volume that justifies the changeover.
Ask for the minimum in the unit you will order: rolls per colour, rolls per pile height, and any surcharge for custom widths. The standard roll range of 2 m, 4 m and 5 m by 25 m clears most minimums fastest.
Plan the layout backwards. Fewer seams means wider rolls and more edge waste; less waste means more seams and more site labour.
Red Flags in Supplier Vetting
What to look for in a red flag is a pattern, not a single poor answer. Three signals should slow a purchase down.
Red Flag 1: No Traceable Roll Labels
A roll with no batch number, no production date and no lot reference cannot be matched to anything. Ask what the label will say, then check the first delivery.
Red Flag 2: A Quote With No Specification
Vague compliance claims with no documents are listed by buyer guides as a reason for caution, and a quote without stated figures cannot be compared.
Red Flag 3: Reports You Cannot Trace
A report with no laboratory name, no number and no method reference cannot be verified. Ask for the issuer, then take the number to the accreditation body. Site checks follow the same logic, as our field planning notes set out.
Building Your Own Supplier Scorecard
A scorecard turns documents into a shortlist. Weight the three rows below, then compare every supplier on the same rows.
Score Point 1: Specification Completeness
Does the quote state pile height, gauge, stitch rate, face weight, backing and drainage in one place? Mark a missing figure as missing.
Score Point 2: Batch and Label Discipline
Can the supplier describe how a repeat run is matched: yarn lot, stitch setting, coating weight and roll label?
Score Point 3: Document Traceability
Take one report out of the pack and verify it end to end. A supplier whose documents survive that test is a different proposition.
Add a fourth row for commercial fit: delivery terms, minimums and the named person who answers a claim.
Frequently Asked Questions
What should I check first when vetting an artificial grass supplier?
Start with what the supplier makes itself. Ask which stages run in its own plant, then request a live look at those lines.
How do I verify a supplier’s test report is genuine?
Send the report number to the accreditation body in the economy where the laboratory is based. It can confirm the laboratory’s status and the scope it is accredited for.
How many samples should a supplier send before a bulk order?
Standard squares are 20 cm by 20 cm, and three to four pieces is the usual pack. That is enough to compare colour and pile in daylight.
Why does batch consistency matter on repeat runs?
Because a repeat run is where drift shows up. Yarn lots, stitch settings and coating weights each move a little. What to look for is the batch record that catches it.
What decides the minimum quantity a supplier will accept?
The changeover, not the area. A plant setting up a colour or a pile height wants a volume that justifies the run, so minimums are quoted per roll and per colour.
How do I compare two suppliers’ quotes fairly?
Rewrite both quotes onto one specification sheet: pile height, gauge, stitch rate, face weight, backing, drainage and delivery terms. Compare equal products, not headline figures.
