SpecificationsTechnical information

SIERRA aluminum pergola is one of the prefabricated garden structures. It is an elegant, fast and cheap solution for roofing your veranda or terrace. In addition, the modern and practical aluminum pergola is available at a low price, it looks great and you can build it with help of two people in one afternoon.

The construction is made of essentially indestructible aluminum profiles and strong polycarbonate with 100% UV protection. Roof panels, resistant to high loads of snow and hail, have a light transmission of over 90%. The pergola thus creates a pleasant shade, but remains richly lit. A unique system for sliding roof panels without additional connecting material and the need of climbing onto the roof to adjust it. The maintenance-free aluminum frame with galvanically treated metal elements is treated with powder paint and is highly resistant to rust, mold or moss.

Thanks to the adjustable anchorage height and sliding support legs, it will suit most common verandas. It can also be used from the side of the house as a carport.
