Who we are

Built in the workshop, proven in the field

TecSol Mechanical Contracting LLC is a UAE-based industrial engineering company specializing in precision machining, reverse engineering, re-manufacturing, industrial refurbishment and EPC-related mechanical works for critical utility infrastructure.

The company has grown from a compact 2,000 ft² workshop into a 12,000 ft² facility in New Industrial Area, Ajman — equipped with CNC machining, qualified welding and heavy refurbishment infrastructure, supported by the group's Dubai engineering office established in 2003.

Our core strength is engineering asset life extension: restoring and re-manufacturing plant equipment that is decades old, often with no surviving OEM. Where a replacement part no longer exists, our 3D-scan and reverse-engineering route recreates it — to the original fit, form and function.

“Satisfy the customer needs — specified or implied, small or big — through a mix of honesty, integrity and social awareness.”
