HEFEX Ltd. with its headquarters in Baia Mare, Maramures county was established in May 2002, its main activity being "The execution of metal structures and parts for metal structures" – 2511 CAEN code.

Our company specializes in the execution and mounting of metal structures, equipment installation and anti-corrosion and anti-abrasion protection. The need to increase the quality of our products, led the company's management to require an audit by The International Certification Network – IQNet and SRAC (Romanian Society of Quality Assurance). Both institutions have confirmed that the environmental management system, occupational health and safety system applied by our company fulfill the requirements of the following standards: ISO 9001:2015, ISO 14001:2015, OHSAS 18001:2007.

The activities certified by these two institutions are:

• Execution and mounting of metal structures, industrial trestle, industrial platforms, silos works, equipment mounting, anti-corrosion protection, anti-abrasion protection;
• Execution and mounting of industrial halls, mounting of installations, equipment for industrial outfits, conveyor belts, industrial lifts, mounting of filters;
• Anti-corrosion and anti-abrasion coating works.

Also, regarding welding, TUV Sud Romania Ltd. Bucharest issued the following documents:

• Certification for our company in accordance with the requirements of EN ISO 3834-2;
• Approval of three welding procedures in accordance with the requirements of EN ISO 15614-1;
• Authorization for welders in accordance with the requirements of EN 287-1.

Ever since our inception, our company signed execution contracts with renowned beneficiaries, participating in the development of projects with a high level of difficulty and complexity. Since the beginning we have done works for Holcim Romania S.A. Aleșd, Turda and Câmpulung, Holcim Slovakia, a mutually beneficial collaboration which continues today, after 9 years. Also, works have been and are being carried out in other Holcim locations (Pitești), and for other known partners that have chosen to work with us because of our reliability and professionalism, such as: Ambient, ATP Exodus, Romaltyn Mining SRL, Cuprom SA, Dywidag România SRL, ADISS SA, STRABAG Gmbh, TR Construction SRL, Transilvania Construcţii SA, Norstal SRL, Martifer Construcţii SRL, Tenaris – Silcotub SA, and so on. Our company is located in the north western part of the country, but it has large scale works in other parts of the country. However, because of the large distances, the transportation cost for our products increases, so we tried to strengthen our position on the northwestern, northeastern and central market.

Given the current conditions, to maintain our market share and growth, we will increase our production capacity, we will reduce losses; our main goal is to provide quality products at competitive prices. During all these years of activity, our company tried to maintain itself amongst the leaders of the field and acquired advanced machinery. To achieve specialized mechanical processing at a higher degree of difficulty, we acquired specialized equipment, including: shot blasting machine, FALCON 3000 cutting machine, PEGAS semi-automated saw, plasma cutting equipment, abkant CNC bending press, metal rolling machine, grinders, electric hoists, chamfering machine, plate bending machine, pipe and profiles, plate rolling machine, welding machines and installations, hydraulic presses, drills, electrodes drying oven, beam with 1,6 tons hoist, lathes, planers, paint spraying equipment, cranes of various tonnages, loader with Manitou telescopic arm, and so on.
