ABOUT US
OUR HISTORY
Our company was opened as “Sonex Metal and Chemical industries S.A.” in Athens, Greece in 1994. The main activity, like still Today, was distribution and sales of steel and metal products to the countries within European Union. In 2002. our company has moved all of it’s business to Belgrade,Serbia to a then newly opened company Sonex Metal and Chemical Industries d.o.o. (S.M & C.I. d.o.o.).In 2003. our company purchases 1000 sq.m warehouse and in 2020. we have purchased and moved to a new modern warehouse, cutting, packing and logistics center measuring 11.000 sqm.Our company has constantly added different materials necessary for building/construction, industry and production sector, like concrete blocks, corrugated sheets etc., so we can proudly say that we are in a position to fully satisfy their needs. S.M. &C.I. d.o.o. is proud to be one of the leading metal and building/construction material supplier in Serbia and region.
Distribution and sales of the building materials and construction steel products for high and low constructions.
ACTIVITY
MAIN MARKETS
Our main markets are Serbia, Balkan region, European Union.
As a steel and building materials supplier, our company serves as a critical link in the industrial supply chain, operating through high-volume,long time relationship-driven transactions that fuel the construction sector. Our B2B model focuses on providing structural contractors and engineering firms with the raw materials—such as reinforcing bars, reinforcing meshes, concrete blocks, steel, copper and aluminum tubes, profiles and sheets etc.—necessary to execute large-scale infrastructure projects. Our value proposition lies in logistical reliability, bulk pricing advantages, and the ability to meet strict technical specifications, ensuring that our partners have the inventory they need to maintain project timelines and structural integrity.
WAY OF DOING BUSINESS
Our Products
OUR CARBON STEEL
- CONSTRUCTION STEEL
REINFORCING STEEL BARS
Our reinforcing steel bars are supplied in diameters from 6mm to 50mm in 6 meters length, and are produced in accordance with B500B standard. We can supply the material according to other standard on request. Every material is supplied with the mill test certificate of quality. They comply with EN 10080 standard. We pack them in 2 tons bundles.
B500 Reinforcing bars steel standard
- Chemical composition
The primary role of the alloying elements in B500 steel is as follows:
- Carbon (C): Increases strength but can reduce ductility if too high.
- Manganese (Mn): Enhances hardenability and tensile strength.
- Silicon (Si): Improves oxidation resistance and toughness.
WELDED WIRE MASH
Welded wire mesh is made by welding steel wires at intersections to form a grid pattern. This type of mesh is commonly used in concrete slabs, walls, and pavements due to its uniformity and strength. It is available in various sizes and gauges, allowing for flexibility in different construction projects.
RIBBED MASH
Ribbed mesh, also known as deformed mesh, features ribs or deformations on the surface of the wires. These deformations improve the bonding between the mesh and the concrete, providing enhanced tensile strength and load-bearing capacity. Ribbed mesh is widely used in reinforced concrete slabs, beams, and columns.
- DEFORMED BAR MESH (GRADES 280 & 420 MPa)
RECTANGULAR MASH
Rectangular mesh is similar to square mesh but with rectangular openings. It is typically used in applications where different load distribution is required, such as in walls and beams. The rectangular pattern provides flexibility in reinforcing concrete elements with varying dimensions.
TOOL STEEL
Tool steel combines selected alloy steel and carbon steel grades, and its high hardness and abrasion resistance characteristics make it ideal for cutting and machining various types of metals. Major alloying elements in tool steel are chromium, molybdenum, vanadium and tungsten. These carbide formers allow tool steel to resist deformation and maintain a sharp cutting edge at high temperatures.
- AISI A2 CHEMICAL :
BENEFITS OF TOOL STEEL
- High Hardness and Wear Resistance: Tool steel possesses excellent hardness, allowing it to withstand high cutting forces and resist wear during machining processes.
- Toughness and Shock Resistance: Tool steel exhibits high toughness, enabling it to absorb shock and resist deformation, making it suitable for applications involving high impact and repetitive stresses.
- Heat Resistance: Tool steel retains its hardness and toughness even at high temperatures, allowing it to withstand the thermal stresses associated with high-speed machining and heat treatment processes.
- Our company supplies tool steel according to AISI A2, AISI D2, AISI H13, AISI 01, AISI M2, AISI M43, AISI S7, AISI W1 and AISI A6 standards.
OUR STAINLESS STEEL
SHEETS /PLATES
We are supplying the sheets/plates in thickness from 0,4 up to 30mm, according to the standards EN 1.4016 (AISI 430), EN 1.4301 (AISI 304) and EN 1.4404 (AISI 316L). The standard sheet sizes are 1000x2000mm, 1250x2500mm and 1500x3000mm. Upon request we can supply the non-standard sheet sizes like 1250x3000mm, 1500x6000mm, 1250x6000mm, 2000x4000mm, 2000x6000mm or cut to the measure sizes or the sheet in a coil. When supplied in a bundle, the sheets are delivered on a wooden pallet of approx. 2 tons.
