Saudi engineering, fabrication and industrial integration capabilities built around precision, execution discipline and field-ready delivery.
Sinsina Industrial Works (SIW) is a leading Saudi industrial manufacturing partner headquartered in Jubail Industrial City. We specialize in end-to-end engineering, precision shop fabrication, modular skid assembly, and seamless equipment integration. Guided by strict international quality codes, client specifications, and practical field requirements, our work ensures optimal operational performance and reliability from shop testing through site commissioning.
At SIW, industrial execution begins with robust, multidisciplinary engineering. Our team bridges conceptual design, detailed mechanical calculations, 3D modelling, and piping layout to deliver fully integrated process packages. By managing interfaces in-house, we eliminate design mismatches, streamline fabrication, and guarantee field compatibility.
Operating from our heavy industrial manufacturing facilities in Jubail, we maintain specialized fabrication yards equipped for high-precision welding, CNC machining, rolling machine and heavy structural assembly. Our deep metallurgic expertise encompasses high-performance alloys and corrosion-resistant materials—including Inconel 625, 316 & 430 Stainless Steel, and high-yield carbon steel.
We deliver shop-tested, plug-and-play modular solutions that minimize field construction risks, footprint requirements, and site downtime. From complete structural skid bases to process piping, valves, electrical wiring, and instrumentation (E&I), every package is integrated and systematically tested under one roof.
Quality is embedded across every phase of our manufacturing lifecycle. Operating under international quality control codes and ISO frameworks, SIW conducts comprehensive Factory Acceptance Testing (FAT), pressure testing, and non-destructive testing (NDT) to ensure field-ready, compliant equipment.
Sinsina Industrial Works commenced operations in 2019 in Jubail, Saudi Arabia, with a focus on engineered skid packages and industrial fabrication. Since its establishment, SIW has continued to build its engineering and manufacturing capabilities to serve the evolving requirements of the energy and industrial sectors.
