GRATTONI Sun Umbrella TRIESTE for Outdoor Catering Areas

A sun umbrella creates shade by blocking direct sunlight with a fabric canopy stretched over a supporting frame. The canopy intercepts ultraviolet rays and diffuses visible light, reducing the temperature beneath it and protecting diners, staff and outdoor workstations from glare and heat. The frame transfers the weight of the canopy and any wind load to the ground; a separate ballast keeps the umbrella stable without anchoring it permanently to the surface, so it can be moved or stored when not in use.

The GRATTONI TRIESTE sun umbrella is opened by raising the central pole and locking the ribs in position. The canopy is then unfurled and tensioned evenly across the ribs. Once the umbrella is upright, the ballast is placed on the base to prevent tipping. When the service period ends, the canopy is lowered, the ribs are collapsed and the unit is folded for storage or transport.

The frame is finished in anthracite, a dark grey powder coating that resists corrosion and ultraviolet fading. The canopy is beige fabric, chosen for its neutral tone and ability to reflect rather than absorb heat. The dimensions of 3000 mm by 3000 mm by 2200 mm give a square canopy that covers a nine-square-metre area, sufficient for a four-top table with surrounding service space. The weight of 20 kg allows two staff members to carry the unit between storage and the outdoor area without mechanical assistance.

Cleaning is limited to brushing off debris and wiping the frame with a damp cloth; the fabric should be kept dry to prevent mildew. No ballast is supplied with the umbrella, so an appropriate weight must be sourced separately to match the expected wind conditions.

The TRIESTE is listed in the GRATTONI outdoor catering range, where it serves as a movable shade solution for terraces, beer gardens and event catering.
