Secondary framing for warehouses and hangars, chassis tubes for modular homes and custom brackets for facades often look identical on a €/kg line while differing sharply in steel yield grade (S350GD vs DX51D, S355 vs S235), base-metal thickness, zinc coating mass and punched-hole accuracy. We structure your drawings into clear Turkish mill and roll-former enquiries.
Z/C/U/Sigma/SHS/RHS), cut length and camber/straightness tolerances.S235JR, S355J2, DX51D, S350GD, S420GD) and EN reference standard required by your structural engineer.Z275, ZM120, or EN ISO 1461 hot-dip galvanising) and measurement basis.e.g. max 2.0 tonnes) for site crane or forklift.EN 10204 2.2 vs 3.1).
We organise offered steel grade, section dimensions, wall thickness, coating mass and theoretical vs scale weight alongside commercial terms—explicitly separating custom roll-tooling charges, laser/punch setup fees, coil MOQs and scrap assumptions.
Any supplier-proposed grade or thickness substitution is flagged as an unapproved alternative so your structural engineer retains sign-off.
For made-to-drawing warehouse purlins, villa floor joists or custom brackets, Technical Factory Review (SS-TECH, €790) or Pre-shipment Check (SS-PRE, €490) focuses on agreed critical dimensions, hole pitches, coating thickness spot-readings where accessible, bundle nesting, white-rust protection and part tags.

Source pre-engineered steel warehouses, industrial factory halls, logistics buildings and aircraft/agricultural hangars—plus purlins, sandwich panels and hangar doors.
Source light-gauge steel (LGSF) houses, steel villas, structural framing kits and complete exterior/interior envelope material packages from Türkiye.
Source PIR, PUR and mineral-wool roof & wall sandwich panels, trapezoidal sheets, standing-seam roofs and flashings for warehouses, hangars, villas and prefab buildings.
Scoped on-site visits in Türkiye with up to 4 or 6 on-site hours, core-area travel included and an English photo report separating observations from statements.
Yes. Share your purlin cutting list, section depths (140–350 mm), hole patterns, sleeve cleats and S350GD+Z275 specification so we can shortlist high-speed Turkish CNC purlin roll-formers.
We document the exact grade and coating difference separately in the comparison matrix; technical equivalence must always be approved by your responsible engineer before ordering.
Yes. Under SS-PRE (€490) or SS-TECH (€790) in our core area, we check agreed accessible dimensions, hole locations, part markings, bundle counts and export packing. Accredited NDT or lab tensile tests are coordinated separately when required.
Because one supplier may calculate theoretical nominal weight while another uses coil tolerance upper limits or excludes punching scrap. Our Quotation Comparison (€290) aligns weight assumptions visibly.
No. Structural engineering, load calculations and code sign-off remain with your project engineer; SerSourcing structures the procurement brief, supplier comparison and site observations around your drawings.
