Sentab Civil Engineering (Pvt) Ltd

Sentab Civil Engineering (Pvt) Ltd is committed to delivering excellence in quality, affordability and corporate governance.

Sentab Trading (Pvt) Ltd

The dilemmas in sourcing reliable welding equipment and consumables for the hydropower projects handled by Sentab Civil Engineering motivated the founders to look at few alternatives and took the challenge being Sentab as the Gini pig itself. Eventually it was the dawn of introducing Tubular IGBT, light, portable and economical single-phase DC ARC welding machine to the Sri Lankan welding industry.

As soon as realized the productivity enhancement of welding and fabrication works of our penstock installation processes at small hydropower projects by using this welder, Sentab introduced RILING portable welding machine to the market in 2014 incorporating its trading arm Sentab Trading (Pvt) Ltd. Sentab took another step forward by introducing RILAND in 2018 as its Flagship brand against the trend towards cheaper and fake products introduced by quick money hunters. The BRIDGE welding consumables introduced in parallel to the RILAND in the same year.

ARC welding is the most popular and common welding for generations in Sri Lanka, Sentab has done pivotal role in generalizing MIG/MAG welding by emphasizing welders and entrepreneurs. Introducing portable and single-phase MIG/MAG welding machines with compatible welding wires at affordable cost makes most of rural industries’ dreams reality.  Heavy-duty portable GMAW(MIG/MAG) machines available with Sentab saves labour and time for repairing of heavy construction machineries, ship repairs and maintenance of cement factories and cause them less shut down period.

Being the pioneer in using Plasma cutting in Penstock installation works of small hydropower projects saving money and time on transporting industrial gases, Sentab is proud to witness more and more penstock contractors follow us to get rid of huge burden of long haul from gas dealers to remote sites.

Tungsten Inert Gas Welding (TIG) is widely used in stainless steel applications, Aluminium welding, and industrial pressure lines where our products both welding plants and consumables are great choice of professional engineers.

Always being a reliable solution provider to our customers, we are sharing our professional knowledge by utilizing social media platforms, especially welding lessons by Sinhala language on dedicated YouTube channel. The innovative attempt, which Sentab made to the Sri Lankan welding industry is a mile stone of the journey to become the first choice of welding solution provider in Sri Lankan welding industry.
