Facilities, Stock & Projects

A look at the stockyards, inventory and installations behind our supply capability across the GCC.

Held in stock

The components a project actually stops for.

These are the items we carry in depth, in the sizes and pressure classes the Kingdom's projects specify most — so a line list is answered from the yard, not from a mill queue.

Pipe 1/2" – 36"
Elbows 90° & 45° LR
Tees Equal & reducing
Reducers Conc. & eccentric
Flanges #150 – #2500
Valves 1/2" – 14"
The difference stock makes

Why the yard beats the mill queue.

Material manufactured to order arrives on the mill's schedule. Material already standing in our yards at Al-Khobar is inspected, documented and released on yours — which is how a supply time measured in months becomes one measured in days.
