VERIFIED MANUFACTURER SHORTLIST & RFQ SCREENING DOSSIER
Sourcing Brief: 4.2 MWp Industrial Parking Lot Steel Solar Carports (Cantilever T-Frame HDG) + 6063-T6 Anodized PV Clamps/Rails
ILLUSTRATIVE CORPORATE SPECIMEN (ZERO CLIENT DATA DISCLOSED): Client names, factory identities, heat/certificate numbers and commercial figures in this specimen are fictionalized to protect strict B2B NDA confidentiality. Scoped commercial/visual engineering record — not an accredited laboratory test certificate or statutory structural sign-off.
01 · ASSIGNMENT REGISTER & EXECUTIVE GATE SUMMARY
5 Turkish candidates were screened against the 4.2 MWp cantilever carport + anodized rail brief. 2 candidates were eliminated early (Candidate D was a trading intermediary without roll-forming lines; Candidate E lacked EN 1090 EXC2 certification for EU export). Candidates A, B and C submitted structured FCA/EXW quotations and passed legal/tooling pre-screening; Candidate B leads on integrated steel + aluminum rail capability.
