UNIC MARKETING PLUS has been involved in the design and production of heavy and medium-heavy metal structures for over 30 years.
The fabrication of heavy metals refers to large-scale production projects that require advanced technology, specific testing, and high precision. We design and manufacture heavy or medium-heavy steel/metal structures, such as columns (or towers), retention tanks, water barriers for dams, bridges, platforms, structural frames for bridges and foundations, as well as other structural frames, etc.

Industrial Fabrication of Heavy Metals
In the industrial fabrication of heavy metals, we specialize in the production of tanks, basic frames for pipelines, and machinery systems for oil and gas installations, reservoirs, industrial fans, etc.
Metal/Steel Construction
In the construction sector, we design and build both heavy structural works, such as steel and glass architectural structures, industrial warehouses, gratings, shelters, and housing modules, as well as light structural works, including railings, mezzanines, metal canopies, steel windows, safety stairs, etc.


Heavy Metal Fabrication for Infrastructure Projects
Professionalism and work ethics have enabled us to establish a strong presence in the field of heavy metal fabrication, serving both public and private infrastructure projects.
We manufacture comprehensive infrastructures, such as towers and metal structures for telecommunications, as well as metal components for large-scale infrastructures, including bridges, industrial ventilation for excavations and highway tunnels, dams, water barriers for transportation and retention tanks, viaducts, components for railway lines, etc.

Certifications for Heavy Metal Fabrication
Over time, UNIC MARKETING PLUS has obtained numerous prestigious industrial certifications, attesting to how the entire production cycle undergoes constant quality control of individual operations: welding, thermal cutting, design, and process controls. Therefore, we provide additional reliability for all our clients.
We have obtained numerous significant certifications, both at the European and international levels, for heavy metal fabrication, demonstrating the quality of our products. Some of these certifications include:
- ISO 9001:2015 Quality Management System Certification
- Quality Policy
- ISO 3834-2:2006 Quality Management System for Welding
- Factory Production Control Compliance for CE Marking of Steel Structures according to EN 1090-1:2009+A1
- Welding Process for Steel/Stainless Steel Structures according to EN 1090-2 for Execution Classes up to EXC3
- Automatic Thermal Cutting Process for Steel/Stainless Steel Structures according to EN 1090-2 for Execution Classes up to EXC3
- Welding Procedure Qualification Records (WPQR) for Steel/Stainless Steel
- Welding Procedures for Steel/Stainless Steel according to AWS D1.1
Non-Destructive Testing (NDT) Methods for Welding
Thanks to our skilled and experienced workforce, the following non-destructive testing (NDT) methods are typically performed in welding:
- Visual Testing (VT) according to UNI EN ISO 17637
- Liquid/Penetrant Colorant Testing (LPT/DPT) according to UNI EN ISO 3452-1
- Electromagnetic Testing/Eddy Current Testing (ET) according to UNI EN ISO 15549
- Magnetic Particle Testing (MT) according to UNI EN ISO 17638
These are surface checks capable of detecting defects on the weld surface. They are typically performed as tests on corner welds.
While to check welds with full penetration, we perform volumetric tests such as:
- Ultrasonic Testing (UT) according to UNI EN ISO 17640
- Radiographic Testing (RT) according to UNI EN ISO 17636-1/2

Documents and Certificates
For the proper execution of a welded product and to comply with required regulations, documentation and manufacturing processes are carried out in a manner that illustrates and certifies the processing methods.
- Material Certificate 3.1 and Traceability
- CE Marking 1090 with related Declaration of Performance (DoP)
- Specifications, certificates, and non-destructive testing reports, as applicable
- Welding Book + Welding Procedure Specifications (WPS)
- Material reference map and traceability from the drawing/board
Heavy Metal Fabrication Equipment

How does UNIC MARKETING PLUS operate
We guarantee our heavy carpentry products because we know how to control all stages and the life cycle of the production process:
- Planning: The moment of planning represents the strategic phase for the perfect execution of each achievement. We have an in-house technical office with structural engineers and civil designers capable of providing a complete executive project. Sometimes, for more complex works, we collaborate with engineering firms and architects to realize their projects.
- Prototiparea: în tâmplăria grea, prototipul 3D la scară este adesea folosit pentru a simula geometrii, faze de asamblare, cinematică etc… Folosim imprimare 3D și instrumente de precizie avansate pentru prototipare
- Design: The design stage represents the strategic phase for the perfect execution of each project. We have an in-house technical office with structural engineers and civil designers capable of providing comprehensive project execution. Sometimes, for more complex works, we collaborate with other engineering and architecture firms for the execution of their projects.
- Production Cycle: All work is carried out by our certified staff, using state-of-the-art technology to achieve the perfect result. The production cycle is constantly checked for certified results.
- Testing: We conduct tests and inspections to ensure the quality of our products and to comply with industry standards.
- Ciclul de prelucrare: Toate lucrarile sunt efectuate de personalul nostru certificat pentru a obtine o realizare perfecta in mod profesionist. Ciclul de procesare este monitorizat constant pentru a obține rezultate certificate.
