About Us


Hilmi KONYALIOĞLU founded a small private establishment about agricultural machinery tools in a humble place in 1932. This establishment, founded during first years of the republic, carried on its activities by keeping its important role in development of regional agriculture with production of machinery and tools which were needed to take agriculture from wooden plow to mechanical method.

The establishment turned into an aggregate corporation with the name “Hilmi KONYALIOĞLU VE OĞULLARI KOLL. ŞTİ.” when second generation was ready to take part in establishment in 1963. Besides, the company took in partnership with some investment companies, which produced long rolling mill, to make contribution to Denizli industry by producing longitudinally-welded steel pipe.

In 1979, the company which was reorganized with the name “KONYALIOĞLU METAL SANAYİ PAZARLAMA” started to steel marketing, rolling mill business and commitment business in addition to producing agricultural machinery. In 1979, our company also started production of agricultural and industrial machinery by founding a new establishment with the name “KONMASAN TARIM MAK. İML. SAN. A.Ş.” by considering conditions of developing marketing.

Our company with marketing and industrial background and experience for 85 years about iron and steel was renamed as “ASKON DEMİR ÇELİK” under direction of D. Aslan KONYALIOĞLU in 1990 and has been carrying on its industrial and marketing activities since then.

Brand Story


A little mess

A little art

Some fun

A little fashion

A little culture

Some nature

A little color

Both chaotic and aesthetic

Both eastern and western

Both mysterious and wise

Both holy and gentle

Both history and modern

Both innovation and tradition


It is Istanbul, a long story from the Neolithic period up to now that whoever wants to find out.

Artepera has got the inspiration from this season. It has fed and sprinkled from this variety and culture. It is now in your face with designs of some cult objects abd some contemporary interpretations.

Artepera is not exactly ethnic, avantgarde, bohem or loft, conservationist. It is an unclassifiable, unrecognizable brand just like Istanbul. Summarily, "it is style owner, different and new".

In the metal tradition, Artepera, who represents the 3rd generation behind a well-established production force, presents portraits of wall decorations, clocks, mirrors, kitchen accessories, furniture and sculptures with designs that give domination, harmony and aesthetics to metal materials.

Artepera aims to be one of the world's leading brands in the field of metal decoration with its design-oriented brand positioning, its inspirational values and unique style that takes its place from this cosmopolitan geography.
