Product range

Six grades, one material

Every grade is drawn from the same soda-lime glass melt and sorted to a different size band. That means consistent chemistry across your whole order — and one supplier instead of five.

Where they are used

Specified into nine industries

Glass beads are chosen where metal media would contaminate the batch and angular media would damage the workpiece.

Paints & Coatings

Milling and dispersion media in bead mills.

Printing Inks

Grinding media where metal pickup is unacceptable.

Agrochemicals

Inert media that will not react with active ingredients.

Automotive

Shot peening of springs, gears and castings.

Aerospace

Controlled peening for fatigue-life extension.

Medical Devices

Cleaning and deburring of precision components.

Cosmetics & Perfumery

Valve and cap beads, mixing balls for aerosols.

Road Marking

Retro-reflective beads for night visibility.

Water Filtration

Support media replacing filter gravel in wells.

Quality control

Every batch is measured, not assumed

Beads are drawn from the melt, rounded, washed, polished and sieved in one continuous line. Samples are pulled at the end of each run and logged against the order number.

Microscopic roundness check

200 beads inspected per sample; minimum roundness recorded per size band.

Sieve analysis

Oversize ≤5% and undersize ≤10% limits verified on every lot.

Certificate of analysis

Chemical and physical data issued with each shipment, traceable to the batch.

Third-party testing on request

SGS / BV reports arranged for customers who require independent verification.

Inside the plant

Output staged by grade, before it is packed

Clear and coloured grades are held in separate bins after sieving, so a shipment can be drawn from one homogeneous lot. Container loading is arranged straight off this floor.
