D&T Steel, Inc. is a trusted steel fabrication company in the United States, known for its expertise in structural steel and custom metalwork. With decades of experience, the company delivers reliable solutions for industrial, commercial, and architectural projects.

Before transitioning to the new line, our production relied on an old automated punch-line system. This setup limited our efficiency and slowed down our overall production speed. Another major concern was whether Akyapak, being a Türkiye-based company, could provide sufficient service and support in the United States. This uncertainty was a critical question mark for us in making our new investment decision.

The drilling performance of the machine is very efficient. Moving from our old system to this line has significantly increased our productivity. On the service side, receiving quick responses has been a major reassurance for us. Overall, we are very satisfied with both the machine and the support provided.

Sümbül Çelik is an engineering and manufacturing company specializing in steel construction for industrial facilities. The company manufactures all steel structural components required by energy, industrial, and production plants.

The company operates from its production facility located in Adana, Türkiye. Its strategic location enables fast response to both regional and national projects, while also serving as a strong operational base for large-scale industrial plant installations.

Sumbul Celik was founded in 2015 by Semih Sumbul, following his 15 years of engineering experience. The company quickly became a trusted partner in steel construction and industrial plant manufacturing projects.

The 3 ADM Beam Drill Line, AST Miter Bandsaw and AFD 10 Plate Drilling Machine provide full automation in industrial steel manufacturing.
Before working with Akyapak, one of our biggest challenges was having to perform operations on different machines. This fragmented process extended production times and reduced our efficiency. We struggled to keep up with increasing demand and had difficulties meeting our delivery deadlines. In profile drilling in particular, we faced significant limitations in both speed and capacity.

Akyapak provided us with a single-machine solution through the 3 ADM 1200 Three Spindle Beam Drill Line. The ability to perform drilling, milling, and countersinking simultaneously on three different surfaces has accelerated our production and significantly increased efficiency. Today, our processes run much faster, with higher precision, and without interruptions.
