The aesthetically pleasing design will cover a full range of buildings from residential properties to commercial constructions. The AstroTM system is also suitable for many fa ade applications with a limited tray length of 6 m. A single cross seam connects the individual lengths and the seam is installed with staggered joints. Perfectly roll-formed trays Each AstroTM tray is cut to the desired length and roll-formed by machine to ensure the highest precision. Our qualified craftspeople guarantee the upmost quality and work to the exact specification you provide. Technical advisory service Our experienced staff is at your service for CAD-drawings cost estimation material supply approved installation companies and other related issues. A selection of detail drawings of flashings and cappings can be ordered from our offices at no charge. Flashings and rainwater goods All our roof and fa ade installations are completed with stylish European engineered looking flashings and cappings. Matching half round gutters and round downpipes are part of our service. The roof drainage system enhances functionality and design. Material Finish Falzonal Aluminium Falzonal prepainted aluminium in LockWelt-Quality is a material specially developed for roof cladding. A wide range of colours allows individualised design options in numerous colour tones. The high plasticity and workability mean that Falzonal is ideal for all types or architecture. Processing the material is both easy and cost effective.

It will give corrosion performance superior to the austenitic grade 316. The low reflective surface finish (2DR) is produced by skin pass rolling the strip with shot blasted rolls. The resulting surface is a uniform matt grey.

The surface will slowly develop the patina typical of copper when exposed to the atmosphere. Oxide (brown) Copper sheets and strips are pre-oxidised on both sides which allows the bright copper phase to be bridged so that a uniform dark brown oxidised layer is achieved. The surface further develops into the natural oxide layer in the course of weathering.

Rheinzink alloy an electrolytic high-grade fine zinc according to DIN EN 1179 with 99 995% Zn degree of purity. Added to this are small quantified amounts of titanium and copper. In addition to other factors the alloy composition is not only of importance for the technological material properties of Rheinzink but also for the natural colour of the Rheinzink patina.
