Processing and export services

Roll-forming lines for trapezoidal, corrugated and tile-profile sheet and sandwich panels; tube mill for galvanized pipe and hollow sections; laser, plasma and cut-to-length lines; perforated sheet punched to order — all in our Dilovası plant. Cutting and processing are charged as separate lines on the offer.

Processing is where the cost actually sits

A fabricator rarely buys steel. A fabricator buys parts, and the difference between the two is cutting, bending, drilling, welding and coating. Moving those operations upstream — to the plant that already holds the material — removes a handling cycle, a transport leg and a scrap stream from the project.

The arithmetic is usually decisive on nesting alone. Cutting parts from a full plate at the mill yard leaves the skeleton where it has value as scrap; cutting them after the plate has been trucked to a workshop means paying freight on material that will be thrown away. On a complex nest that is 12–15 % of the tonnage.

What the plant does in-house

Cutting covers laser to 20 mm and plasma to 50 mm on flat material, tube laser for profiles and hollow sections, and 3D laser where the part is already formed. Heavy plate is cut to size on a cut-to-length line and coil is slit to strip width.

Forming covers press brake bending to the length of the machine, plate rolling for shells and cylinders, and dished ends pressed and, where the material requires it, normalised afterwards.

Finishing covers shot blasting and priming, hot-dip galvanizing to EN ISO 1461, and welded fabrication where the assembly leaves as a part rather than as a kit.

Each service has its own page with the machine envelope, the tolerance it holds and what has to be on the drawing.

• Laser and plasma cutting, tube laser, 3D laser
• Slitting and cut-to-length from coil
• Press brake bending, plate rolling, dished ends
• CNC punching and drilling
• Shot blasting, priming, hot-dip galvanizing
• Welded fabrication: catwalks, guardrail, stairs, frames

What a processing enquiry needs

A drawing, or a DXF, and the quantity. That is the short answer, and the two things most often missing from it are the material specification and the tolerance that actually matters.

A laser holds a far tighter tolerance than a plasma torch, and paying for the tighter one on a part that will be welded into a frame is money spent on nothing. Conversely, a hole pattern that has to match a bought-in component needs the tolerance stated, not assumed.

For anything that will be galvanized, the design check happens before cutting: vent and drain holes, closed sections, overlaps and lifting points. Fixing those on the drawing costs nothing; fixing them after the steel is welded costs the steel.

Processing your material or ours

Both routes are normal. Steel bought here is processed before it leaves, which is the simpler case — one supplier, one certificate chain, one delivery.

Material sent in from elsewhere is processed under the same terms, with the customer's mill certificate travelling through the job and the processing documented separately. This is the usual arrangement for galvanizing, where fabricated steel arrives from another workshop, and for cutting where a customer holds their own plate stock.
