Detailed description
There is no single grade of hook and loop, only grades matched to a job. The material, the width and the put-up below are the three variables worth settling before the first order, because changing any of them later re-opens the price.
What the buyer is choosing
Grade and backing are separate decisions. The same woven face is supplied plain for stitching, coated with acrylic for panels, or coated with rubber for rough and low-energy surfaces. Buying the face and the backing as one item is what produces the 'it stuck for a week then fell off' complaint.
The material question
The construction is a woven hook and loop face in the standard grade: enough hook density for a normal closure, priced for volume rather than for a five-year service life. If the application cycles more than a few thousand times, ask for the higher-density weave instead of paying twice for the same part.
How it is quoted
Widths are slit from the master roll in one millimetre steps between 10 mm and 150 mm, held to plus or minus 0.5 mm. A width that is not on the list is a slitting instruction, not a new tool, so it does not add lead time once the master exists.
What ships with the goods
Certificates are issued per lot rather than per year, and REACH and RoHS declarations travel with the shipping documents. OEKO-TEX documentation is available on request for skin-contact applications.
Checking it on arrival
Open one carton from the middle of the pallet, not the top. Condensation and compression both show up in the middle of a stack, and the top carton is the one that was packed with the most care.
Ask for a sample at your width; it ships in seven days and it settles the substrate, colour and hand questions faster than any specification sheet.
