SIDMA focuses on iron trade, through the operation of its integrated Steel Service Centers.Τhe trade of steel products coming either directly from extrusion operations done in the steel plant or following processing in the company’s facilities is included.

Processing activity

It includes processing steel coils of various quality levels, to be processed into a variety of forms on the basis of its clients’ special needs. The shot-blasting plant is able to remove external oxidation from various materials and protect them by applying a special paint. Cutting of thick sheet iron into special dimensions and cutting long products into specific dimensions is done in a gas-cutting procedure (copy router) and a saw respectively.

Provision of services

It includes sales procurement on behalf of third parties, as well as income derived from processing products for third parties.

Other activities

They include mainly the sale of scrap, which is produced from processing the company’s raw materials.

Levelling and Cut to length lines

The cut to length lines level the coil material and then cut it into pieces, with dimensions according to the customer’s request. The basic components of a typical cut to length production line are the decoiler, the leveller the shear and the packer. The leveller consists of a set o working and back up rolls which exerts controlled pressure over the surface of the material. At the end of the levelling process, a pair of blades (shear) cuts with high accuracy the levelled material into specific lengths. Each sheet produced piles up into a stacker and the bundle is ready for packing.

Slitter Line

The slitting lines slit coils into strips. The basic components of a typical slitter are the decoiler, the feeder rolls, circular cutting heads and the recoiler. As the coils unfold on the decoiler it passes through the rotating circular knives which then cut the material into sets of strips. The strips are then driven to the recoiler and during the cutting process the sides of the coil are trimmed off. The slitting line can process galvanized, hot rolled, cold rolled, inox and other types of material.

Trapezoidal Line

The trapezoidal line can process galvanized, and pre-painted inox material. As the materials are decoiled they pass through a set of forming rolls. The effect of these rolls is a trapezoidal profile to the surface of the material. The basic parts of the line are the decoiler, a group of rotating forming rolls which deform gradually the processed material,  he shear which cuts the deformed material into pieces off specific lengths, and finally the stacker.

Stainless Steel Polishing Line
The polishing line processes only inox material. During the polishing stage the material processed passes through rotating polishing heads and if required there is another stage where the material passes through a rotating brushing head. Next, a plastic self adhesive membrane is attached onto the surface of the polished material for protection.

Metal Blasting & Painting Line

The Metal blasting & Painting line processes a wide range of hollow sections, rectangular - circular cross section beams and plates. The material is first cleaned of possible debris. A set of turbines shoot small metallic particles at high speed over the surface of the material and remove any kind of scale. Then the material is driven to the painting stage where a set of painting nozzles inject a protective water soluble paint over the surface of the material. This paint will protect the material later from external environmental conditions.

Οxygen Flame Cutting

The oxygen flame cutting machine is a CNC machine, which cuts plates into shapes according to the customer’s requirements. The cutting “information” is transferred to the machine electronically from a PC and is based on electronic drawings provided by the customer. The motion of the cutting nozzles is controlled by computer software resulting in high accuracy cuts.

Compliance with legislative requirements and Environmental protection are part of the SIDMA Business Strategy.

The company takes part in the collective packaging and product management system provided for in Law No. Ν.2939/01 (Hellenic Government Gazette 179/Α/01), which is set up by the "HELLENIC RECOVERY RECYCLING CORPORATION S.A."

Following certification of the Occupational Health and Safety Management System, the company is obliged to develop and implement the Environmental Management System, according to ISO 9001:2008 in all its production and administrative activities.
