In the world of modern architecture, the use of elements that provide both visual beauty and structural efficiency has gained special importance. One of these magnificent elements is metal spiral staircase. The design and implementation of these structures not only requires precise engineering knowledge, but is also an art that takes place in the hands of experienced professionals. In the meantime, Rezai's spiral staircase and round staircase collection is known as one of the pioneers of this industry, relying on years of experience and using modern technologies. Building a high-quality round metal staircase is a complex process that requires strict standards from material selection to final installation. In this article, we will examine the detailed and step-by-step construction steps of these decorative and strong structures.
The importance of choosing round metal stairs in interior and exterior design
Round and spiral stairs are an ideal option for villas, duplex apartments and commercial units because they take up less space than ordinary and sword stairs. Metal, as the main material in the construction of these stairs, provides high flexibility to create complex geometric forms. In Rezai's spiral staircase and round staircase collection, the main focus is on combining the strength of steel with the elegance of the design. Due to its high resistance to environmental factors and the ability to accept various colors, the round metal staircase has a very long life and can act as the focal point of the decoration of any building.
The first stage: expert advice and accurate measurements of the field
The first and most critical step in the construction process is to accurately measure the project site. The experts of Spiral Stairs and Rezai Round Stairs check all the environmental parameters by being on site. The height of the floor to the floor of the floors, the dimensions of the stairwell, the thickness of the ceiling and the position of the adjacent walls are among the things that must be recorded with millimeter accuracy. The smallest error at this stage can lead to the staircase not being level during installation. At this stage, the type of use of the space is also taken into consideration to design a staircase that fits the traffic and the architectural style of the environment.
Second stage: engineering design and 3D modeling
After collecting field data, it is time for software design. In the design unit of Spiral Stairs and Rezai Round Stairs, using advanced software such as AutoCAD and SolidWorks, the 3D model of the stairs is drawn. In this step, the calculations related to the inner and outer radius, the number of steps, the height of each step (Riser) and the bottom of the step (Tread) are performed. Compliance with ergonomic standards is the main priority to prevent user fatigue and provide life safety. Also, in this phase, all the details of the connections and gravity points of the structure are calculated so that the round metal staircase does not vibrate or sound in the long term.
The third stage: selection and supply of high-quality metal material
The final quality of a round staircase directly depends on the type of alloy and the thickness of the sheets used. Rezai spiral staircase and round staircase always uses standard steel sheets (ST37) with thicknesses appropriate to the live load of the structure. For the main chassis of the staircase, high-diameter industrial pipes or thick sheets cut by precision machines are usually used. The selection of material in this collection is based on static calculations so that the stairs have the ability to bear heavy loads and do not change shape against tensile and compressive stresses.
The fourth stage: cutting parts with CNC technology
Precision in cutting metal parts guarantees clean work in the final stages. In the Rezai spiral staircase and round staircase workshop, the parts related to the bottom of the stairs, treads and side sheets (armors) are cut using CNC laser or plasma cutting machines. This technology allows slim or modern designs to be executed on metal with very high precision. The use of automatic devices not only increases the speed of production, but also makes all the stairs completely identical and symmetrical in terms of size and shape.
Fifth step: rolling and bending of sheets and profiles
Creating the desired arch and curve in the round metal staircase is the most challenging part of construction. There is a need for heavy rolling machines to make stairs around the pipe or two axis sheet stairs. Rezai's spiral staircase and round staircase specialists roll the side sheets according to the designed radius with high skill. This process should be done in such a way that no knots or distortions are created in the metal body. Accuracy in bending makes the path of the stairs smooth and without sharp angles, which plays a significant role in both beauty and ease of use.
The sixth stage: initial assembly and welding of the structure
After preparing all the parts, the assembly process begins in the workshop environment. In the rezai spiral staircase and round staircase series, special jigs and fixtures are used to keep the parts stable in order to maintain the level of the structure. Welding is usually done using carbon dioxide (CO2) or argon welding, which have more penetration and a much cleaner appearance than traditional welding. Each step is carefully connected to the main chassis, and the connections of the central column or side sheets are firmly established. Observing the principles of engineering welding prevents the deformation of the structure due to high heat.
The seventh step: Grinding and polishing metal surfaces
A round luxury metal staircase should not have any welds, folds or unevenness on its surface. After welding is finished, it is time for fine work. The craftsmen of Spiral Stairs and Rezai Round Stairs use special burs and granular sandpapers to finish all the connection points in such a way that the metal surface looks completely integrated and polished. This step has a direct impact on the quality of the final painting; Because the smallest defect in the foundation will be clearly visible after painting.
Eighth step: design and construction of railings and stair guards
Safety is the first word in round stairs. In addition to the role of protection, the railings bear a large part of the beauty of the staircase. In Spiral Stairs and Rezai Round Stairs, all types of metal, wrought iron, modern (laser cut) or combined with other materials are designed and manufactured. The railings must be connected to the body of the stairs in such a way that they have the maximum resistance against lateral pressure. The curvature of the railings should also be exactly parallel to the arch of the stairs to maintain visual harmony. The handrail is also installed with high precision so that it is comfortable and safe for the user to touch.
Ninth stage: foundation and final coating (painting)
Use of proper coating is essential to protect stairs from rust and corrosion, especially in wet areas. In the Rezai spiral staircase and round staircase workshop, the entire structure is first degreased and cleaned. Then high-quality stainless linings are used. Finally, the round metal step is covered with electrostatic (powder) paints or epoxy and polyurethane paints. Due to baking in the oven, powder colors have a very high resistance to impact and scratches and provide customers with a unique variety of colors.
Tenth step: transfer and installation at the project site
The last step is to transfer the heavy metal structure to the building site and install it. Round stairs are usually built monolithically or in large pieces. The installation team of Spiral Stairs and Rezai Round Stairs installs the stairs in place with complete equipment and observing all safety precautions. The staircase is connected to the building frame (metal or concrete) through the plate of waiting columns or industrial rollbolts. The final alignment and ensuring the absence of the slightest vibration during the load test is the last step performed by professional installers.

Safety standards in the construction of round metal stairs
In the construction of round metal stairs, compliance with national building standards is mandatory. These standards include the minimum width of the floor of the stairs in the traffic path, the maximum height allowed for each step and the standard distance between the railings to prevent falls (especially for children). These standards are carefully controlled in all stages of production in the Rezai spiral staircase and round staircase collection. Also, the structure's vibration calculations are done in such a way that the structure does not experience annoying vibrations when used by several people at the same time.
Mixed materials next to the round metal staircase
Although the main chassis is made of metal, other materials can be used for the bottom of the stairs and the handrail to give a more luxurious effect to the space. A combination of oak or walnut wood for the floor of the stairs, the use of laminated tempered glass as a protection, or the use of hidden lighting (LED) at the edge of the stairs, are among the services that are offered to customers in Rezai's Spiral Staircase and Round Staircase. Metal as infrastructure provides the possibility of implementing all these creative ideas.
Maintenance and care of metal stairs
The metal round stairs produced in Rezai Spiral Stairs and Round Stairs are made and painted in such a way that they require minimal maintenance. However, periodic cleaning of the surfaces with soft cloths and avoiding very sharp objects hitting the painted body will help to maintain its shine and newness for many years. If the stairs are installed in the outdoor space, periodically checking the connection points and making sure that moisture does not penetrate into the lower layers of paint is doubly important.
