Supplying Saudi water & sewage infrastructure since 2010
Onixa Company supplies and manufactures valves, ductile iron fittings, fire hydrants and accessories for water and sewage projects across the Kingdom of Saudi Arabia.
Authorized agent & distributor of HUHANG Technology Group, a manufacturer certified by the Saudi National Water Company (NWC).
The market challenge & our answer
On Saudi water projects the bottleneck is material approval and availability. We remove both.
Mega-projects accept only client-approved materials, and approval cycles stall procurement.
An NWC-approved vendor distributing HUHANG, an NWC-certified manufacturer, with materials already accepted on major programs.
Imported valves and fittings mean long lead times and unpredictable stock.
A wide international sourcing network plus local stock, so orders are delivered in record time.
Fragmented suppliers complicate warranties, QA documents and site support.
One partner for supply and manufacturing, with warranties, submittal support and after-sales service.
