Steel structure manufacturer in Turkey: from design to installation
Steel structure buildings combine strength, fast erection and low maintenance. Their components are designed and fabricated in a controlled production environment, shipped to site in knocked-down (CKD) condition, then bolted together and lifted into place with cranes.
We design each building for its use and location, for projects ranging from single buildings to large industrial structures.
