Product & Services


Buildings are typically delivered in just a few weeks after approval of drawings.Foundation and anchor bolts are cast parallel with finished, ready for the site bolting. In India the use of PEB will reduce total construction time of the project by at least 50%. This also allows faster occupancy and earlier realization of revenue.

Diesel Generator

Automatic Transfer Switch & Manual Changeover Switch

Automatic Transfer Switch can automatically transfer load from mains power to emergency power without operator intervention. When mains power fails or voltage drop below 80% of normal voltage, the ATS will start emergency generator, after a preset time of 0 to 10 seconds(adjustable). At rated speed, the ATS will transfer load to emergency power with available size ranging from 40A to 4000A. There is a switch suitable for every project’s need.

Professional Lighting For Construction Sites

Refer to that professional service area where specific lumen (in the terms of Lux) is required to the specific types of lights to ensure the energy efficiency complying exact technical parameters.

Indoor & Outdoor Lighting

Lighting Tower

Light towers are mobile light sources often used at construction job sites and mines to facilitate night-time work. Typically, an array of powerful lamps is mounted on a telescopic mast anchored to a highway-capable chassis, which houses a diesel or gasoline engine that drives a generator for supplying electricity to the lamps.

Our light-tower range is designed for use at high altitudes and in extreme weather conditions. The new light tower is equipped with four 200W-400W LED lamps, capable of illuminating a 15,000-square-foot area with an average brightness of 15 lux. The HiLight V4W incorporates a manually operated vertical mast, which rotates 360 degrees and provides a maximum operating height of 12 feet.


We offers design, consultancy, site survey, supply, installation and maintenance of Lightning Protection System (LPS) through out Bangladesh. Our product ranges are-

  • Advance LPS

We offerthe most advanced Lightning Protection System Technology Early Streamer Emission (ESE). Early Streamer Emission have a great coverage range and higher accuracy in catching the strikes reducing risk around its coverage. This OPR range delivers improved performance in early streamer initiation and propagation, and represents further progress in terms of lightning protection, operating autonomy and ease of maintenance.One terminal covers a wide area, that makes it very economical as it only requires only 2 down conductors to complete the loop. Our products standard covers by this ESE-102 system are French national standard NF C 17-102 – 2011, NFPA 780, RTN(Russia), IEC etc. These products are also UL and CE listed.

  • Conventional LPS

We offer the most known system for protection from lightning is the conventional mesh conductor type lightning protection system which codes as NFPA 780. Which complies with IEC, IEEE and other international standards as well as BNBC standards. This is the most traditional and old standard for around a century and most used all across the world because of its efficiency and low maintenance caliber compared to other systems. Yet this is the traditional system and have some technological backlog compared to other modern systems.
