Test Sieves Brass Frame 200mm dia

Highly Accurate Premium Quality Warranty Included

This comprehensive series of Standard Laboratory Test Sieves provides precise aperture calibration for particle size distribution across geotechnical, aggregate, cement, and asphalt testing. Spanning macro-coarse aggregates down to micro-fine powders, the range is engineered to maintain aperture geometry under continuous mechanical agitation and sonic sifting.

The large-diameter 30 cm and 45 cm Galvanized Iron (G.I.) frames are built for high-volume coarse aggregate fractions up to 125 mm, resisting heavy impact and abrasive wear from crushed stone and gravel. For fine aggregates, soils, sands, and pulverized binders down to 38 microns, the 20 cm spun brass series features seamless, low-friction side walls and precision woven wire mesh to eliminate particle entrapment and ensure consistent nesting with matching pans and covers.
