Stirex specializes in equipment for preparing, transporting and applying construction mixes, including plastering machines, pneumatic conveying systems, mortar pumps and mixers, shotcrete equipment and system components.
Stirex is a specialized machine-building brand developing equipment for mechanized construction and finishing technologies. The Stirex machine-building plant is part of the ORTIS Group, whose team has extensive experience in supplying, operating and servicing European mechanized finishing equipment.
According to the manufacturer, the team draws on more than 20 years of experience with European equipment, while the machine-building plant itself has spent more than five years developing, engineering and manufacturing its own equipment and technological solutions. This describes the team's experience and manufacturing activity rather than a claimed founding date for the brand.
Stirex also emphasizes in-house engineering, manufacturing, equipment service, spare-parts production and component availability. This infrastructure is particularly relevant for professional construction equipment that requires scheduled servicing and replacement of working components.
Plastering machines are one of Stirex's core product directions. The official range includes systems such as PSMulti, PS380 and AG500 for different electrical supplies, output requirements and operating conditions. They are designed to prepare and deliver dry construction mixes intended for machine application.
Stirex PSMulti can operate from 220 V and 380 V supplies, while the PS380 and AG500 families are aimed at higher-power three-phase applications. Selection should consider not only motor power but also required output, delivery distance and height, material properties and conditions on the job site.
The main selection criteria are explained in the ToolsArmenia guide on how to choose a plastering machine.
Stirex develops not only individual plastering machines but also components for a broader material-delivery workflow. The PTS V120 pneumatic conveying system is designed to move dry mix from the storage or loading point to the work area and can be used with mobile silos and compatible plastering equipment.
This system-oriented approach is particularly relevant on larger sites where manual transport of dry mix and continuous loading from bags can become a limiting factor in finishing productivity.
The Stirex portfolio also includes mortar pumps for transporting different types of construction mixes. The MP100 and MP220 ranges address mortar-pumping applications, while the manufacturer lists floor screeding, surface repair, wet shotcrete, injection work and other processes among applications for the MP100.
Mortar mixers and Stirex TRK shotcrete machines further expand the product scope. This gives the brand a wider specialization than plastering machines alone, covering mix preparation, transport, pumping and spray application.
For a plastering machine or mortar pump, important parameters include output, maximum delivery distance and height, operating pressure, motor power, electrical supply and the properties of the material being processed. Shotcrete equipment additionally requires consideration of maximum aggregate size, required air consumption and the intended application process.
When comparing different types of construction machinery, the ToolsArmenia equipment and machinery selection section provides additional guidance.
Mechanized finishing equipment requires periodic replacement of working and wear components such as rotor-stator assemblies, hoses, connectors, spray guns and other parts. Stirex officially identifies equipment servicing, spare-parts production and component supply as part of its operating model.
Stirex's wider manufacturing capability is not limited to construction-site equipment. The plant also engineers and supplies solutions for production and packaging lines, including palletizing systems and the Stirex LPS15 palletizer. This reflects a broader industrial-automation dimension of the brand's engineering activity.
A distinguishing feature of Stirex is its focus on the complete mechanized finishing process. The brand provides not only individual plastering machines but also related equipment for material transport, mixing, pumping, shotcrete application and ongoing service.
For buyers, this structure makes it possible to consider equipment as part of a complete technological workflow. Each model should still be selected according to the actual project volume, available electrical supply, material type, required output and delivery distance.
At ToolsArmenia, Stirex equipment can primarily be considered within plastering machines and light construction equipment. When configuring a working system, also consider the required spare parts and consumables. Base the final choice on the work process, required output, supply voltage and the technical capabilities of the specific model.
