Material information

Steel

Steel is produced primarily from iron. Pure, metallic iron is a fairly soft, silver-white metal. In the Earth's crust is iron with about 6 % the second most common metal and the fourth most common element.

From iron ore and coke, pig-iron is produced in blast furnaces, which becomes to steel by reducing the carbon content.

After the design-engineering of the steel, occurs as an corrosion protection mostly a galvanizing and an enduring color covering according to RAL or micaceous riron ore DB.

Cast iron

The side panels of the benches consist of cast iron with lamellar graphite or spheroidal graphite iron. Cast iron with lamellar graphite is the eldest cast material on the base of iron and it is characterised by excellent absorption properties and its resistance to corrosion.

The essential components are iron, carbon and silicon. Compared to normal cast iron, a significantly lower sensitivity of wall thickness is achieved.

Spheroidal graphite iron has the same basic material, but during the melting of the cast iron, the adding of magnesium effectuates, that the graphite changes its form from lamellar-shaped to ball-shaped, which causes a higher absorption of impact energy.

Larch

Larch is a homelike, supremely durable wood with an initially ginger impression, which changes after a few month outdoor weathering in a silver-gray coloring. Larch wood has good resistance characteristics and is regarded as the most robust coniferous wood.

Bilinga

Bilinga is a tropical hardwood from sustainable cultivation, in which important ecological resources are protected. The wood is a medium- to heavy-weight wood with extreme favourably resistance characteristics, which are significantly higher than those of beech and oak.

Resistance category: 1

Definition: very durable, for a life-expectancy beyond 25 years.

Wood is a natural product and is a subject to the conditions of physical principles which are affected by differences of temperature and differences of air humidity. We strictly reject any warranty for cracks and curves, splicing, branches, grey-black discoloration – they can arise because of the reaction of iron ions, as well as resin leaking from the wood. Further claims, particularly claims for damages of any kind are excluded.
