Pneumatic Telescopic Mast is a latest innovation, forming part of an integral communication of systems. These masts are light weight and meant for quick erection, ranging from 5 to 25meters height. Pneumatic masts are extended by using low pressure air. The accessories supplied either from a compressor, in case of smaller masts, from a foot pump.

Tubular winch up Masts

- We have a mast range in size from 10 meter to 80 meters, for wind measurements, all are manufactured to the international standard. Our QC wing follows stringent quality control process. For adoption, satisfaction of our valued customers globally.

We are offering shear connectors or shear studs with following features.

The use of shear load connectors and reinforcing bar couplers in the construction of sports stadiums has increased rapidly in recent times, as their benefits over other building methods have become more widely recognized.

The use of reinforcing bar couplers can provide significant advantages over lapped joints. Design and construction of the can be simplified and the amount of reinforcement required can be reduced.

Concrete structures are normally designed with joint sat appropriate places to allow movement to take place. The design of these joints is important for the overall design to function correctly. In most cases, doweled joints, corbels and double columns can be replaced by joints incorporating shear connectors.

We manufacture Shear Connectors/Studs sizes starting from 9.5 mm to 25 mm Dia, in different lengths max 300mm. We are producing Shear Connectors as per following Standards:
