From the roofing of major civil, agricultural and industrial complexes to gazebos and sheds for the garden,
millions of square metres of Tecno Imac sheeting have been installed throughout the world over the past two decades.
Here are some examples of the versatility of Tecno Imac covering solutions.
Roofing of a hotel complex in Central America. Terracotta effect imacoppo® roofing sheets and fastenings, laid in various lengths
Roofing of agricultural livestock shelters in Germany. Terracotta effect greca 143® roofing sheets and fastenings
Roof of timber cabin in Italy. Standard ecolina® grey roofing sheets and ecolfix fastenings
The production technology that makes our sheeting solutions unique
Coextrusion is a manufacturing process based on the deformation of plastic a substrate, involving the simultaneous processing of different components so that they emerge from the production machine in the form of layered bonded sheets that combine the best features of the constituent materials.
The Tecno Imac production stations are organised in units of three extrusion machines. In each extrusion machine, the constituent mixture components (resins, plasticisers, stabilisers, pigments etc.) are fed through hoppers into a cylindrical chamber. Here the mixture is heated and compressed with worm screws s until it reaches the coextrusion flat head where the layers created by the individual extruders converge to form a coarse sheet. This is then laminated in a calendering press and it is passed on for final profile shaping.
Since the creation of the Polimglass®, patented in 1992, the technology evolution and the availability of new engineering plastics drove further development and the emergence of new materials based on the coextrusion of three layers, such as Ecotres®, which is the base material for making ECOLINA®, GRECOLINA® and ECOLTHERM® sheeting as well as their relative accessories, as well as HSP® (High Strength Polymer), from which the new line of IMACROOF® is made
Total quality assurance
Tecno Imac has generated a procedures manual that ensures ultimate quality throughout the entire production process
In-line production checks
Production staff continuously monitor the correctness of the extrusion parameters, and carry out visual inspections on the surfaces
Tecno Imac has been certified to ISO 9001:2008 quality standards by the RINA body.
Routine material sample tests are carried out daily, including microscopic investigations, mechanical checks to verify resistance to hail impact as well as weatherometer tests.
The final inspection stages are implemented during packaging as the products are prepared for shipment to the distribution network and key customers.
“The achievement of consistently high production quality is enshrined in the Tecno Imac corporate philosophy and represents the goal of our Quality Laboratory, which is equipped with state of the art equipment. The lab supervises the entire production process to ensure the highest quality of production – free from defects in workmanship.”
