Flagpole lifespan and durability in Finland

A flagpole is a long-lasting purchase, but its durability depends on the material, the weather and care. The Finnish climate, with its frost, ground frost and autumn storms, puts a strain on the pole and foundation. This guide describes what affects the service life of a flagpole and a flag.

Material and service life

• Fibreglass does not rust or rot, and according to Suomalaisuuden Liitto it is preferred because it is durable and easy to care for. Sunlight can fade and roughen the surface over time.
• Aluminium does not rust the way steel does, but corrosion can appear at joints and fittings.
• Steel lasts a long time when the corrosion protection is intact.
• Wood is prone to rot, particularly at ground level, and its service life depends largely on painting and rot protection.

The materials are compared in the guide to flagpole materials.

Weather and location

A windy site, such as a sea or lake shore or an open field, puts more strain on the pole than a sheltered garden. By the sea, salty air increases corrosion of metal parts. Frost and ground frost can move the foundation, making the pole lean. Designing the pole and foundation for the conditions therefore affects the service life. Installation is described in the guide to flagpole installation.

Care extends service life

According to Suomalaisuuden Liitto, regular care and washing of the pole and checking the fittings is appropriate for example every spring after the winter. Moving parts such as the halyard, pulley and top wear fastest, and replacing them in time prevents greater damage. Under section 29 of the Building Act, a structure must meet the essential technical requirements that are essential to safety if its failure could endanger people. Maintenance is described in the guide to flagpole maintenance.

Flag size and the load on the pole

The manufacturer designs the pole for a flag of a certain size. In the Ministry of the Interior’s table, the flag’s size is matched to the pole’s length so that the flag’s height is about one sixth of the pole’s length. A larger flag increases the wind load. Flying the flag in a storm also strains the pole and flag, and according to Suomalaisuuden Liitto the flag is not raised in strong wind or a storm.

Guarantee and liability for defects

Many manufacturers state a guarantee period for the pole. Under the Consumer Protection Act, however, a guarantee does not limit the statutory liability for defects, so the seller’s liability for a defect can last longer than the guarantee. Consumer rights are described in the guide to buying a flagpole.

The life of a flag

According to Suomalaisuuden Liitto, Finnish flags are made of polyester for its durability and colourfastness, and they stand up well to the country’s changeable weather. Wind, sunlight and dirt wear a flag in particular. The flying outer edge of the flag usually wears first. According to the Ministry of the Interior, a flag on the pole is ideally clean and intact, and the flag can be washed and repaired. The flying times, which also limit wear on the flag, are described in the guide to flag rules.

When a pole or flag is taken out of use

A pole taken out of use is construction waste, and the municipal waste advice service can explain how it is handled. A worn flag is disposed of with dignity according to Suomalaisuuden Liitto, by burning it or cutting it into pieces so small that the flag cannot be recognised. According to the Association, the flag is not reused.
