Our Five Core Divisions
Comprehensive materials and engineered solutions designed for demanding industrial environments.
Oil & Gas Piping Systems
We are a leading stockist supplying carbon steel pipes (seamless & ERW), stainless steel, ductile iron, and specialized alloy piping components for upstream, midstream, and downstream projects — including pipes, flanges, fittings and valves from world-leading manufacturers such as Sumitomo, Benken, Mega, Ulma Forge and Velan Valves.
Water Desalination & Treatment Components
Specialized components, chemicals, and pressure vessels engineered for Reverse Osmosis (RO) plants, wastewater management, and industrial water filtration.
PVC-Coated Industrial Fabrics
Heavy-duty, weather-resistant technical textiles designed for architectural tensile structures, truck tarpaulins, shade netting, and protective industrial covers.
Fire Protection Systems & Fittings
UL/FM listed equipment for fire suppression and life safety installations in commercial and industrial facilities.
Property & Facility Management
Alongside our supply divisions, the company develops and manages commercial and industrial property across the Kingdom — including the storage yards, storehouses and sales offices that underpin our own distribution network.
Facilities, Stock & Projects
A look at the stockyards, inventory and installations behind our supply capability across the GCC.
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.
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.
