U Profile

U profiles are preferred as load-bearing or supporting elements in construction, steel structures, lightweight steel structures, automotive, electrical-electronic, metal goods and energy sectors, for industrial structures and steel buildings. Due to their high load-bearing capacity they offer up to 40% material and cost advantage compared with heavy steel structures. They also provide ease of production, procurement, shipment and assembly, making steel building construction faster and more economical.

Roof Walkway

The roof walkway is designed to provide safe access on roof surfaces; its special pattern prevents slipping and it is mounted to standing-seam sheet ribs with a dedicated fixture. It is designed for all weather conditions and corrosion resistance. It is manufactured in lengths of 100–3000 mm and heights of 50–150 mm in stainless steel (SS304), hot-dip galvanized steel (S235JR) and pregalvanized steel (DX51D+Z). Typical use is sandwich panel and trapezoidal sheet roofing.

Flat Bar (Lama)

Şahin Demir Sanayi sells angle, lama (flat bar), silme, square, profile and wrought iron in Karabük. The firm entered iron and steel trade in 1999 and bought a rolling mill in the New Industrial Section in 2003. The hot rolling plant under investment is planned to produce round, lama, silme, square and angle bars at 70,000 tonnes per year. While that investment continues, the company still trades lama among its commercial steel range.
