Classic outdoor lampposts – history
Cast iron lamp posts are a solid part of most classic and old cities. In the very beginning the illumination started using stearin. Later more powerful lamp oil and gas was installed and nowadays we use LED bulbs.
The history for cast iron used in townscape and buildings can be originated back to the early 1400 where pots and pans was invented in cast iron.
The cast iron was produced from doubtful iron ore using charcoal which could only make the cast iron float and thereby possible to poor into the form that was made by sand.
By luck the foundry men could then clean the castings from the penetrated sand. In the beginning the purity of the molten liquid was difficult to control and they had no tools for measuring the temperature. The quality was therefore in the beginning quite poor and the grade was something like grey iron. Grey iron is still being used in pumps, hydraulics and widely in the automotive industry. Grey Iron is not possible to bend or forge and therefore difficult to correct or repair if the outcome was poor in the casting process.
In the 1500s and the 1600s cast iron was more common but still very expensive and extremely time consuming to produce. During the 1700s the melting process had been improved by substituting the charcoal. Of course also the industrialization helped cast iron by getting more common and was now becoming an alternative to forged and wooden constructions. It was used in Buildings as windows, joints, fences or ornaments.
In the 1800s cast iron was always being used in buildings either in the construction itself but also windows.
Up to 1948 cast iron was only available in grey iron. Despite a low tensile strength Grey iron offers a high compressive strength, slow degradable even without surface treatment. In the case of fire cast iron withstands temperatures up to 1100degrees.
The advantages of using cast iron was clearly proven. As of today forming is being done in various mixtures of sand, which give a demand for 1degree of draft and no rounding should be less than 4mm.
Thereby cast iron has smooth surfaces and beautiful curves which are still the great advantage of cast iron in comparison with steel and forged iron that typically is straight and sharp edged.
A major step in cast iron happened in 1948 by inventing nodular iron. Nodular iron has a far higher tensile strength which was highly needed in the industry.
In 1962 a Danish company called DISA invents the vertical molding principle which speeds up the production dramatically. The DISAMATIC principle is still state of art machine and vital for automotive parts.
Our standard program of classic outdoor lamps.
Our classic lamps are all cast in Vejen in Denmark. First we do the casting, cleaning, metallizing, 2-k primer, 2-k topcoat whereby we offer a 30 years cast-iron-surface guarantee.
We have 8 different lamp heads in our program and all named according to the cities where they are still a vital part of the townscape. You will find the lamps in following cities; Copenhagen, Ribe, Skælskør, Fredensborg, Gråsten, Kalundborg Viborg and Tranekær.
SR, The Ribe Stand has ladder steps for decoration but also making cleaning and bulb-change easier. In SR range, we offer 4 different heights; 1,4meter; 1,9meter; 2,7meter and the maxi of 3,0meter.
SG is the more modern design having a 6-edged smooth design following from bottom to top. In all stands you will find an inspection hatch that you can decorate with a logo or crest.
Wall arms we use for buildings both on the flat surface but also we offer an elegant corner fitting with ornament if necessary. For porches we offer tophung lamps.
Naturally, our lamps follow the regulations of CE and IP54. All lamps has been prepared for LED bulbs. Corrosionclass is evaluated to 4/5, and 5 is the highest score.
