With a well-defined direction in place, the path to realizing our Vision is based on fundamental drivers, instrumental in achieving our goals. Industrialization is a process that happens in countries when they start to use machines to do work that was once done by traditional labor. Industries are the most important aspect of the economy. Using better technology, it becomes possible to generate more possessions in a shorter amount of time. Sectors such as Agriculture, Energy, Transportation, Material Handling, Heavy Duty Machineries, Electric Appliances, Textile and etc; are versatile parts of International Trading.
On the other hand, Road infrastructure is vital in assisting the Nation’s economic development by moving people and goods. Sectors such as Civil Construction particularly roads, buildings, airports, power, and ports have become very attractive for both domestic and foreign contractors & investors. This is due to relatively low entry barriers in these markets, a strong project pipeline, and a considerable opportunity size.
As a result, the market as a whole has become a mixed bag of opportunities in which different types of players are participating, concerning the common interest of doing business. Orienting toward market demand, THE RELIABLE BUILDERS (TRB) is the most imperative Sister Concern of OTBL. Facing new challenges and opportunities, TRB has emerged as a leading enterprise in Bangladesh in the field of Infrastructure construction & International trading of Industrial Machineries.
The Reliable Builders has been a key partner in the infrastructure growth of BANGLADESH, since the company’s founding TRB has explored & expanded to meet the needs of the region as the demands for improved infrastructure increase.
