Do flag poles need a base?

Yes, flag poles should always have a base! There is a specially designed fitting for each flag pole, and you will find this with the respective flag pole under the category Pole Fitting, or in the parts list under Pole Fitting. So that the base sturdiness is guaranteed, a base design is delivered with the flag pole, with a detailed guide on how to set it up.

As a rule, base holders are cemented down, into which the flag pole is easily fitted after the fact and centered with a clamp ring. The pole can always simply be pulled out from the base holder or a new diameter can be installed.

Recommended minimum foundation sized for normal soil pressure and cement quality B 25 for all pole holders:
7 + 8 m – 80 x 80 x 80 cm
9 – 12m – 100 x 100 x 100 cm

A layer of gravel serves for good drainage of the base fitting.

But flag poles can also be anchored into the ground with a ground tube or a rotating device.

In which increments should the poles with booms be separated?

So that the booms cannot hit against each other and a uniform image can form, the poles should have a distance between each other of twice the boom length + at least 40 cm.

Example: Boom length 120 cm = 120 cm + 120 cm + 40 cm = 280 cm distance

Is a building permit required for wall mounts?

Different building authorities, cities, and municipalities regulate the erection of flag poles differently. So it is recommended to inquire with the responsible authorities about the requirements for a building permit.

Is it possible to refit a boom to a flag pole?

Generally, almost all flag poles can be refitted with a hoistable boom.

For poles with a maximum internal diameter of 40 – 70mm, we can twist off our canisters and refit a 360-degree rotational boom head. The refitting of existing flagpoles with hoistable booms is normally very time consuming, so it must be precisely evaluated if a refitting is worth it and/or of a new pole would not be more cost-effective.

Is it possible to borrow flag poles?

We also loan out mobile flag poles (loan poles) and telescoping flag poles. The deliverability always depends on the inventory at the time.

To build up a concrete supply, we require the exact amount and duration of the loan of the desired poles. Please contact us, we will be happy to advise you.  [icon type=”icon-right-circled” /] To the contact form

Is a building permit required for setting up a flag pole?

Different building authorities, cities, and municipalities regulate the erection of flag poles differently. So it is recommended to inquire with the responsible authorities about the requirements for a building permit.

In Switzerland, authorisation is generally not required for movable structures. However, if the pole is used for long-term advertising and let stand for longer than three months, the municipality must be reconsulted and/or informed. But as long as the poles are placed on your own property and there are no complaints against it, installing flag poles is an uncomplicated affair.

Does the base and/or flag pole have to be set up by a professional company?

With a little technical skill, it is possible for DIY-er to set up the base and flag pole themselves with the accompanying guide. It is not absolutely required for this to be done by a professional company.

What is AlMgSi1F28?

This is a premium aluminium alloy primarily distinguished by its resistance to corrosion, light weight, and high retention of value. The alloy stands for aluminium (Al), which contains set amounts of magnesium (Mg) and silicon (Si). F28 indicates the strength class/durability.

What is the difference between a conical and a cylindrical flag pole?

The conical flag pole gets narrower the higher up it goes. Example: the base diameter amounts to 101 mm and the upper diameter 64 mm. With a cylindrical flag pole, the diameter remains consistent all the way through. The most-sold flag poles are cylindrical, two-part poles. The tubes inside the pole are tapered with a joint, i. e. from 80 to 64mm or from 100 to 80mm.

What are the advantages of a bracket pole / boom pole?

The bracket poles have changed from the flagpole for national or Canton flags to advertising flags. Now the flag pole is one of the most important means of representing the CI (corporate identity) of your company. The advantage of the bracket/boom is that your flag remains visible even without wind, and so serves as a point of orientation.

What are the advantages of an internally installed hoisting device?

Flag and pole are exponentially better secured against theft and/or vandalism if the rope guide is inside the pole. Oftentimes poles with an internal rope guide are more comfortable in their operation (i. e. through crank activation or a pole opening). Such poles are also less prone to filth and moisture. Furthermore, the internal rope guide is less noisy, because it can’t hit against the pole.

How do I dispose of a flag pole?

<p style=”text-align: justify”>In contrast to wood, plastic or steel, aluminium is the only material that can be recycled.</p>
<p style=”text-align: justify”>We will happily dispose of your old flag poles for you.</p>

How tall is a normal flag pole?

It depends on both the height of the building and the size of the flag. The flag poles should be twice as tall as the flag to maintain a good aesthetic ratio, and to achieve a safety margin to the ground.

Otherwise there is no general answer to this question. A flag display blueprint helps with placing the right mast and/or flagging technology on the right spot to best represent your company or community, and catch people’s attention.

How do I measure my flag pole's height?

The easiest way is to take a measuring tape or a piece of rope and pull it upward toward the flag.

Where do I find base plans for a flag pole?

Do I have to pick a standard size?

For custom designs, no. However, there are sizes which are not recommended for cost reasons. A standard width is 100 or 150cm. A flag with a width of 160cm has to be printed on fabric 200cm wide, so this makes 40cm of scrap.

It should also be noted that boom lengths for flag poles are limited to 150cm, and sometimes can only be delivered in the (hoistable) standard sizes of 80/100/120/150cm. International flags are also deliverable only in the stated standard dimensions.

When do I use which type of flag?

There are 4 types of flags to choose for flag poles:

  • Hoistable flags
  • High-format flags (flapping flags)
  • Outrigger flags
  • Banner flags

Hoistable flags are designed for all locations with various wind patterns, including very windy areas. However, the format is less optimal than advertising flags.

High-format flags are also designed for various wind patterns. If no outrigger is available, this format is optimal for company and advertising flags because it has a large surface area. But contrary to the outrigger flag, this flag is only fully legible when it’s windy.

Outrigger flags are the typical advertising flags today. Even without wind, the flag is 100% visible. You can choose from hoistable and non-hoistable outriggers. The non-hoistable outrigger is also designed for very windy areas. Outrigger poles, however, must have a greater gap between the poles to prevent them from beating against each other.

Banner flags are used rather seldom nowadays. The typical characteristic of this flag type is the rung above it with the trapeze-like rope suspension and possibly a rung below, too. The banner flag is still used for traditional and church festivals and events. Like the outrigger flag, the entire printed image is also visible without wind, although these flags are not designed for strong winds due to their strong sail effect.

What is flag confection?

“Flag confection” describes the various ways to hang a flag. Look here at our examples of flag confection. Each flag practically fits its pole. A major difference, however, is the term “outrigger”. Outrigger flags are finished at the upper edge with a hemstitch and naturally require an outrigger arm to fasten it. A qualitatively good hemstitch is finished with a seat belt. For a non-hoistable outrigger, this must amount to an even 5cm so that an outrigger tube with a 28mm diameter can be introduced. For poles with hoistable outriggers, the hemstitch only amounts to 2cm and a 6mm piping can be sewn into it.

High-format and outrigger flags are laterally fastened with carabiners every 60cm along the cable run or onto the pole with fastening bands. You can secure banner flags above with carabiner hooks, and an annular pulley fixes the banner below on the pole. Finishing hoistable flags calls for laterally fastening carabiner hooks or ropes and loops on the pole or the cable run. ALUART has the proper flag confection for every flag pole.

What flag size is right for my flag pole?

There are no set rules for which flag size is meant for which pole height. It’s actually a matter of taste. For quadratic flags we recommend around ¼ of the pole, so a flag of up to 200x200cm with an 8m flag pole. For banners we suggest about ½ of the flag pole, so a 120x500cm flag for a 10m flag pole with an outrigger. Please note that there are set guidelines for the various flagging techniques.

What flag size do I need for which poles?

We recommend the following sizes:


Nominal height in m Flag size in cm
5 80×200
6 100×300
7 150×350
8 100×400
9 120×500
10-12 120×500


Hoistable flags landscape

Nominal height in m Flag size in cm
5 80×80 / 80×100
6 100×100 / 100×120
7 150×150 / 120×150
8 200×200 / 150×200
9 200×200 / 200×250
10 250×250 / 250×300
12 250×250 / 250×300


How large is a normal flag?

Every size and shape can be made. But advertising flags are often hung with local or national flags and these are made in standard sizes.

Advertising flags are generally high-format, with the most common sizes being:

  • 80x200cm
  • 120x300cm
  • 150x400cm
  • 120x500cm

You also receive all national and regional flags in these sizes by default. For private purposes, in Switzerland more quadratic Canton and Swiss flags are common in 100x100cm to 150x150cm.

Landscape flags are common in the European Union countries, with sizes between 100x150cm and 150x250cm being suitable depending on the flag pole.

But the size of the flag still depends on the size of the flag pole. High-format hoistable flags and banners should cover about half of the visible pole’s height, while hoistable flags (without wind) should cover the top third of the pole. Flags or banners should never be touchable from the ground, so as to avoid vandalism! Of course every other format can be produced, but the set regulations of the flagging technique applied should be considered.

How long does a flag last?

Flags number among the most physically strained textiles around. Flags are blown by the wind x-thousand times per day. A general statement on the durability of flags cannot be made because the respective wear on a flag is influence by many factors. The differences in the various fabrics should also be noted. Lighter flag cloths with only 60-80gr./m2 are less, or not at all, designed for external display. Normally flags intended for external use are between 100 and 180gr./m2. The heavier the cloth, the more difficult the 100% silk-screening. That’s why today, heavy cloths cannot always be printed in the same brilliant colours as those on lighter cloths. If your flag is needed for long-term display, then this benchmark lasts for around 6-12 months.

However, extreme weather conditions can cause damage or even destruction of the flags within a few hours. Furthermore, environmental influences like heavily used streets or industrial areas have a negative impact on the flags’ lifespans. But remember this: Flags are wear-and-tear items. Through proper handling and care, the lifespan of a flag can be lengthened exponentially. To protect the cloths (but also the poles!) we recommend quickly pulling flags indoors during Beaufort 8 wind speeds (storm), or else the flags’ warranty is forfeit. It should also be noted that flags can be blown away and never land without touching trees, poles, wires or buildings. Extreme turbulence can occur from disrupted wind between houses – especially highrises – which greatly damages the seams. Should such damage become visible, the flag should be caught immediately and restored to good condition. Possible rips and serrations will get larger otherwise.

To keep presentation of your company or community clean, please make sure to switch dirty or shredded flags and banners for newer ones, otherwise your flag will quickly give off a negative image.

How do I take care of my flag?

If the flags are retrieved during a storm and taken down and washed every 6-8 weeks (fabric 60 degrees C, knitted fabric 90 degrees C) and possible shredded corners are resewn, the lifespan can increase greatly.

Wind & weather

Can the flag pole begin to rust from the inside from condensation?

Condensation, if anything, is unharmful because all of our poles’ parts do not rust.

What is a Beaufort?

A Beaufort is a unit of wind speed (wind strength); named after Admiral Sir F. Beaufort, 1806.

The Beaufort Scale:

  • Wind strength in Bft 0: still wind, (0 kn)
  • Wind strength in Bft 1: ight draught (1 kn – 1 bis 2 m/s – 1 bis 5 km/h)
  • Wind strength in Bft 2: ight or gentle breeze (4 bis 6 kn – 2 bis 3 m/sec – 6 bis 11 km/h)
  • Wind strength in Bft 3: weak breeze, weak wind (7 bis 10 kn – 4 bis 5 m/sec – 12 bis 19 km/h)
  • Wind strength in Bft 4: moderate wind (11 bis 16 kn – 6 bis 7 m/sec- 20 bis 28 km/h)
  • Wind strength in Bft 5: brisk wind (17 bis 21 kn – 8 bis 10 m/sec – 29 bis 38 km/h)
  • Wind strength in Bft 6: heavy wind (22 bis 27 kn – 11 bis 13 m/sec – 39 bis 49 km/h)
  • Wind strength in Bft 7: strong wind (28 bis 33 kn – 14 bis 16 m/sec – 50 bis 61 km/h)
  • Wind strength in Bft 8: stormy wind (34 bis 40 kn – 17 bis 20 m/sec – 62 bis 74 km/h) flag must be brought indoors
  • Wind strength in Bft 9: storm (41 bis 47 kn – 21 bis 24 m/sec – 75 bis 88 km/h)
  • Wind strength in Bft 10: heavy or strong storm (48 bis 55 kn – 25 bis 28 m/sec – 89 bis 102 km/h)
  • Wind strength in Bft 11: hurricane-like storm (55 bis 63 kn – 29 bis 32 m/sec – 103 bis 117 km/h)
  • Wind strength in Bft 12: hurricane ( >64 kn – >33 m/sec – >118 km/h)

Simulation: increasing Beaufort value

The video shows an increase in the Beaufort value from 0 to 12. Depending on wind strength the waves, spray formation, scent, and behaviour of the ship will change.

How do I find out the current wind strength in my region?

Along with the various wind gauges available on the market, you can also inquire online about your area’s current wind speed:

Switzerland: www.sma.ch
Germany: www.wetter.de
Austria: www.wetter.at

Weather warnings are also transmitted through the radio. So you don’t forfeit your warranty, you need to retrieve the flag upon presence of the wind speeds stated!

How stable is the pole tube while unflagged?

The pole tube is stable for speeds of up to 130 km/h while unflagged.

Shipping & Legal Information

How long is the delivery time for flag poles and flag pole parts?

Stocked products, like flag pole parts, can be shipped within two to three days.
The delivery time for flag poles is between one and two weeks.

How long does the warranty and/or liability for defects last?

We give a 5-year warranty on aluminium flag poles and a 2-year warranty on all flag pole parts upon handing the goods to the customer. Exempted from this are retail parts (plastic injection parts, nylon cords, small parts, etc.) and all damage done intentionally, gravely carelessly, or through improper use or treatment and all damage done as an act of nature (e.g. wind speeds over Beaufort 8). The poles are calculated for a flag cloth size of up to 150 x 400 cm (width x height). The flags must be retrieved before very strong winds or a storm. Location and flag size must be considered when selecting a flag pole. Should the location be especially prone to wind, ALUART AG or the local representatives should be consulted during selection.

Warranties can only be valid if the poles’ and pole parts’ manufacture, as well as flag delivery, were carried out professionally and by our directions, and appropriate maintenance was regularly conducted.

The importer or representative of ALUART AG themselves clarify the legal and/or binding technical stipulations/guidelines in his/her country or the supplying country and inform the customers in the event that such stipulations deviate from those of Switzerland. There is no liability in the event of standards deviating from those of the supplying country. Apart from that, the general business terms of ALUART AG apply.
