Rectangular umbrellas as a practical sunscreen

The shape of a parasol is selected according to practical aspects and personal taste. Round umbrellas have not served their purpose, but they are displaced by their rectangular competitors. For good reason. A rectangular one parasolcan be placed better. For example, it can be placed directly against the house wall and thus serve as awning replacement. Several rectangular umbrellas next to each other form a coherent protection area. This variant is often used in the outdoor dining areas.

Structure and function of a rectangular screen

The sizes, materials and frame variants are different. But the function of a rectangular sunshade is no different from that of a round one – no matter if as a small one-meter screen for the balcony or as a ten-meter umbrella for the sun terrace.

A sunshade consists of a mast of wood or metal, which carries the frame with the collapsible umbrella, as well as a stable foot, the umbrella stand, For smaller umbrellas a wall mount is possible. An exception are the increasingly popular traffic light screens. Here no central mast disturbs, because the roof oscillates freely at a laterally oriented arm. Many umbrellas have a kink mechanism at the top to align the shade to the sun. The mast must catch the whole load, the foot provides stability on the ground. Wind pressure can multiply the weight of the screen. Very large rectangular screens require a central wind hole to balance the pressure and not let the screen stand out. Every umbrella tolerates a bit of rain. Heavy rain is only prevented by clothing made of weatherproof acrylic materials. In uncomfortable weather and storms, each screen should be folded up and secured to prevent damage.

Rectangular parasol: differences and models

Rectangular umbrellas offer many different models and dimensions in the trade. The shapes of the canopy vary between square and rectangular. While smaller umbrellas for the balcony are traditionally opened and closed by hand (push-up mechanism), large umbrellas and rectangular patio umbrellas are equipped with a cable operated by means of a crank. Depending on the available space you can choose between:

– Rectangular screen in different dimensions with center mast
– Half umbrella (rectangular parasol, whose mast is attached directly to a wall)
– traffic light or free-arm screen (side mast with flexible screen suspension)

Rectangular parasols as an ideal replacement for awnings

Especially in the catering and hotel industry, rectangular parasols are used as solitary screens or in combination. Several umbrellas next to each other provide shade even on larger areas and open areas and provide protection against the sun’s rays.

Rectangular umbrellas are considered stylish and are easier to use than awnings. For many buildings, awnings and other roofing are not possible for legal reasons or are not desired by the homeowner for optical reasons. Here, rectangular parasols offer a viable alternative and serve as variable roofing for the summer months. Rectangular umbrellas are clearly superior to their round counterparts and are used wherever a transition of the shade to a house wall is desired. In the small version rectangular screens even fit on mini balconies and offer year-round protection in the waterproof version. When selecting your rectangular screen, make sure that the fabric quality is good.

Attachment and installation of a rectangular screen

The basis for free-standing parasols is the umbrella stand. He must be heavier than the screen itself, kippelfrei and secure and fix the screen firmly. Simple models for balcony or patio are made of plastic and are filled with sand or water to achieve the necessary weight. A move is then possible only with much effort. Rollers should be used for transport, so as not to scratch the decking. The rod (from mast can be no question in small umbrellas) is simply clamped in the holder. Balcony balustrade constructions are also popular with balcony parasols.

In strong gusts of wind smaller umbrellas have to be folded in, because otherwise they can fly away. For large rectangular umbrellas only umbrella stands made of stone in question, with the mast is inserted into a recessed metal sleeve. Many terrace owners use structures embedded in the ground. For the catering area in the city area, however, the umbrella stands must be transportable. For private use also garden tables with a hole in the middle can be used, which, however, are rarely found on the market. High-quality umbrellas have a sturdy buckling mechanism, so that sufficient shade is achieved at every position of the sun. Very good products are offered by brand manufacturers from Germany, Austria and Switzerland such as Glatz, Doppler, May, Garpa and Zangenberg.
