The Company Salemo & Merca Lda, was created in Seixal on 18th of August 1982 in Portugal by their actual manager’s partners: Salemo de Almeida Madureira and Joaquim Elias Sabino Merca.

In the beginning the company was turned for the metal assemble of structures and metal-mechanic, and quickly entered in the labour of equipment and components for the electronics industry of high precision and telecommunications.
Consequently, with the certification for the products we win a strong position in the sector and a real presence in the market.

In the beginning of 90´s, with the development of the activity, the company need to increase the investment, in substructure production equipment.

At this turn, we assert in the technological renewal for the labour system, with the insertion of new technological equipment with resource to the CNC (Computer Numerical Control) machines.

This Company initiate its activity with a cover area of 100m2 today there’s more than 11.500 m2 and with a total surface of 30.000m2.

In 1994 with the problems of physical limitation area, the company bet in the construction of a new establishment in Palmela with a 20.000m2 area, where they level a nave with 6.000m2 of covered area.

The investment between 1994 and 1996, allows the company to reorganise his structure, to do new innovating and ambitious projects that as been perspective. This investment was around the 5.000.000 €, which permit a new space and new equipment to the company.

One of the new spaces was the construction of an R.W.T.S. (Residual Water Treatment Station), the acquisition of a Zinc Coating Automatic Line, a Punch machine with guillotine, Bending and Lath CNC machines.

Therefore in March of 1996, was a change to a new and modern local, full with the most recent productive resources and labour conditions that was decisive to increase national and international market quote.

SANTIOLI SRL is a leading company in the design, development, production and assistance of lines for the surface treatment of stainless steel, aluminium, copper and zinc in SHEET METAL or COILS, based in Italy and operating all over the world.

The company is empowered with 20 years of experience in the machine design and assistance sector for leading companies in the field. SANTIOLI lines are synonymous with INNOVATION, COMPETENCE AND RELIABILITY. The care of customer relations, the support in all phases of the interaction and the quality of each intervention, are one of the fundamental points of the company vision.

The new generation of grinding and polishing lines is the result of years of planning, that allowed to bring all possible innovations in terms of automation and improvement of the quality and speed of work in the surface processing sector. Automation has made it possible to reduce human intervention to a minimum, especially those at risk, making the machine fully automatic and without stopping the process.

grinding for
For more than 60 years, our family-owned company has been able to use special handcraft techniques to give metal surfaces the given surface structure or the necessary brilliance. We specialize in the manufacturing of grinding to produce complicated and usually not to be processed with grinding machines surface structures.



Due to our many years of know-how, we are able to process different materials such as aluminum, copper, brass, gunmetal, steel or even stainless steels and to achieve the desired surface through defined work steps such as grinding, polishing and high-gloss polishing. The components to be machined can be blanks as well as prefabricated, turned or milled parts and workpieces.



Our customer base is made up of a wide variety of areas such as electroplating companies, companies in the lighting industry as well as suppliers to the automotive industry and others.



The constant exchange with our customers also enables us to respond flexibly to short-term customer requests, while adhering to punctuality. Last but not least, a perfect quality control ensures that the final result is exactly what the customer wanted. If you are still looking for a reliable partner for the surface treatment of your products, we are the right partner for you.
