Combining the durable highly reflective surfaces of Almeco products with the precise rigid curvature and light weight takes solar of structural panels, concentrating mirror structures to a new level in terms of: ■ Choice of installation ■ Low structural weight ■ Freedom from the breakage problems of traditional structures ■ High rigidity and strength ■ Ease Highly reflective, tough surfaces Almeco has, over nearly 50 years, developed its experience in the production of formable mirror surfaces based on aluminium reflectors. Their most recent developments have brought to the solar , market a...

advantages Simplicity Large scale modular structure Installation Design flexibility Mirrors are supplied complete with rigid backing shaped to customers’ specification. Thanks to their unique production technology, single element curved mirrors can be produced with apertures up to 6500 mm. Light weight (about 50% compared with traditional solutions) and robust mechanical properties result in easier and more economical installation with low breakage losses during assembly. parabolic mirrors can be supplied with small concentrating apertures for ‘micro’ installations and with radius of...
