industrial footprint
One accountable partner.
Every critical link.
Longsheng connects four manufacturing bases in Henan with product engineering, testing, export packing and global logistics. Buyers get more than material — they get a supply system designed for repeatability.
Chemistry, grain size and packing records connected to delivery.
One commercial relationship across abrasives and refractories.

One source.
More possibilities.
From high-purity white alumina to dense refractory aggregates, our portfolio is built around the chemistry, grain and performance your process demands.
