Saman Dezhpars Company was established in 1385 with the aim of providing distinguished technical and engineering services in the field of metal and steel structure construction, industrial and building steel structures, as well as the construction of halls and bolted and nutted steel structures, relying on the experience, expertise, and technical knowledge of its specialized technical workforce.

With the increasing population and development of urban societies, the need for high-rise buildings with strength and quality has become apparent. However, factors such as the disparity in the speed of supply and demand for construction, lack of expertise and technical knowledge in construction groups, deficiencies in supervision, and proper implementation of building laws and regulations have led to a decrease in the desired quality of building foundations.

Saman Dezhpars Company aims to enhance its construction and production capabilities for various types of industrial and building steel structures, providing welded and bolted and nutted structures with high quality and precision in the shortest possible time at a reasonable price, ensuring customer satisfaction, which is the company’s capital.

**Metal Structure Installation:**
Saman Dezhpars Company, equipped with installation facilities such as tower cranes and overhead cranes, declares its readiness for the installation of conventional and high-rise welded and bolted and nutted steel structures. Good quality in installation, along with precision and speed of work, will result in time savings for a project.

**Metal Structures:**
Saman Dezhpars Company, with three production plants covering a total area of 12,000 square meters, is ready to produce a minimum of 1,000 tons of industrial and building steel structures monthly in the form of welded and bolted and nutted structures. The company is equipped with advanced equipment and tools from reputable domestic and foreign brands.

**Structural Calculation and Design:**
The company offers calculation, design, and consulting services for optimizing the construction process, utilizing experienced designers and specialists. Advanced software is employed for the optimization and adjustment of weight in metal structures.

**Optimization and Control of Structural Drawings:**
Saman Dezhpars Company, with its experienced designers, provides services for recalculating and optimizing old and heavy drawings, aiming to optimize the construction process and scientifically lighten the structure.

**Workshop Drawings (Shop Drawings):**
Preparation of workshop and shop drawings for communication with the production line workshop is another service offered by the technical office of the company.

**Estimation and Feasibility of Metal Structure Projects:**
The company conducts estimation and feasibility studies for structural projects, providing necessary consultation and guidance to clients in the planning stages before project implementation.

**Non-Destructive Testing (NDT) of Welds:**
The required level and percentage of non-destructive tests for welded structures are determined based on the Iranian Structural Welding Code – Regulation No. 228. These percentages are not mandatory and can be customized according to the type of structure and its application before starting each project.

**Advantages of Bolted and Nutted Steel Structures over Welded Structures:**
The company lists several advantages of constructing bolted and nutted steel structures compared to welded structures, including speed of execution, installation speed, construction quality, material savings, safety and stability, lower costs, fire resistance, no need for workspaces, global prevalence, structure corrosion resistance, and the ability to be used in emergency management.

**Calculating the Costs of Steel Structure Construction:**
The analysis of the total cost of a steel structure depends on various factors, including the type of structural section design, the volume and weight of the structure, the construction duration, the type of welding electrode used, the amount of welding and cutting, the type of cleaning and painting, transportation costs to the installation site, and the cost of towers or cranes. The differences in prices among various manufacturers stem from these factors.

**Amount of Scrap Sheet Consumption in Metal Structure Construction:**
The amount of scrap sheet and steel alloy consumption in the construction stages of a metal structure depends on the designed drawings and the width of sheets purchased by the client. Generally, it varies between 3% to 6% of the weight of the sheet and steel alloy used in the project. This amount can be higher in special projects with unique designs, but in normal and standard construction works, this percentage is usually considered. Structures with bolted and nutted connections and the presence of sandblasting can increase this amount.
