The present century is the age of speed, innovation, and integration of industry and technology. On the other hand, by increasing importance of speed in developmental activities for provision of better services in construction arenas, the value of concrete as a pivotal element in prefabricated concretes and development affairs is more than ever. Today, the use of concrete is ten times the use of steel in most countries and concrete is commonly used in various industries of all societies. As well, increase in the population size and the need for construction of concrete structures have made concrete as the most important material of the 21st century. The huge volume of construction projects reflects the fact that construction in our country is part of our national capital and industry. Meanwhile, one of the effective factors in preserving this national capital is paying attention to the national construction guidelines and regulations. In this regard, prefabricated concrete structures are of utmost importance. But it should always be borne in mind that concrete construction is satisfactory if implemented in accordance with technical standards. In fact, execution of each concrete structure consists of five important steps, namely molding, reinforcing, concreting, treating, and assembling the mold, each of which requires experience and expertise. With this approach and considering the movement of our beloved country on the development path, Qazvin Salemkar Concrete Industrial Co. started its activities in 1996 with the support of a group of compassionate native specialists in an area of six and a half hectares to supply all concrete components needed by various industries. The major products of this company are used in road construction, building, water and sewage, and electricity industries. Qazvin Salemkar Concrete Co. uses highly qualified and experienced personnel as well as modern equipment to provide customers with a quality product complying with national standards.
