What DEGA does

Dega Demir ve Galvaniz Sanayi A.Ş. (DEGA) is a Turkish industrial manufacturer specializing in fasteners and welding consumables, operating from a single vertically integrated campus in Esenyurt, Istanbul. Founded in 1982, the company produces DIN/ISO-compliant standard bolts and screws across property classes 4.8 through 12.9, custom project-based special fasteners (wheel bolts, studs, nuts, rivets, concrete screws), and copper-coated GMAW/MIG/MAG solid welding wires in SG2 G3Si1 and SG3 G4Si1 grades. The complete production chain is managed in-house — multi-stage wire drawing, in-house tool and die manufacturing (CNC, wire-EDM, grinding), multi-station cold forming, controlled-atmosphere heat treatment, zinc coating, and 100% automated sorting — providing full process traceability from raw material to finished shipment.

DEGA's production technology is anchored in Marposs Brankamp process control deployed across 50+ cold-forming machines, three Mectron-based 100% sorting lines combining 360° laser dimensional scanning with eddy current hardness verification, controlled-atmosphere heat treatment furnaces (with a recent 2025 upgrade adding a second burner and additional circulation for hydrogen embrittlement relief), and an in-house toolroom that supports die manufacturing and rapid changeover. Quality management is supported by IATF 16949 automotive certification (valid through 22.05.2027), ISO 9001, ISO 14001, ISO 45001, TÜV SÜD certification, and TSE CE marking for welding wires under the EU Construction Products Regulation — a regulatory qualification stack that constitutes a meaningful barrier in automotive and construction supply chains.

Commercially, DEGA operates a direct B2B quotation-based sales model with no public pricing or e-commerce channel, targeting automotive OEMs and Tier 1/2 suppliers as the primary segment, with secondary penetration into construction and infrastructure (structural bolts, concrete and masonry screws) and general manufacturing and fabrication. The company engages customers through a direct sales team, a website contact form that routes inquiries to sales, quality, and technical departments, and downloadable PDF catalogues, technical data sheets, and safety data sheets. Packaging formats range from 15 kg spools to 250–300 kg drums for welding wire, with bulk packaging for fasteners. The company is a private Turkish joint-stock company (A.Ş.) and does not disclose revenue, customer names, or geographic footprint beyond its Esenyurt production site.

Core offering

DEGA manufactures cold-formed steel fasteners (DIN/ISO standard bolts, socket head cap screws, machine screws, self-tapping/self-drilling screws, structural bolts, wheel bolts and studs, nuts and rivets, concrete and masonry screws) and copper-coated GMAW MIG/MAG solid welding wires (DEGA SG2 G3Si1 and DEGA SG3 G4Si1). All production — wire drawing, cold forming, controlled-atmosphere heat treatment, zinc coating, and 100% sorting — is managed in-house at a single Esenyurt campus, supplying industrial buyers in automotive, construction, and general manufacturing on a quote-based sales model.

Product overview

DEGA Demir ve Galvaniz Sanayi A.Ş. is a Turkish manufacturer of fasteners and welding consumables operating as a vertically integrated single-campus production facility. The product portfolio consists of three core product lines: Standard Fasteners (DIN/ISO-compliant bolts, screws, and structural fasteners in property classes 4.8–12.9), Special Fasteners (custom project-based fasteners including wheel bolts, studs, nuts, rivets, and concrete/masonry screws), and Welding Consumables (GMAW/MIG/MAG solid wires—DEGA SG2 G3Si1 and DEGA SG3 G4Si1 grades). The company manages the complete manufacturing chain in-house—from wire drawing and cold forming through heat treatment and coating—to maintain quality control and traceability. Production capabilities include Marposs Brankamp process monitoring on cold-forming presses, controlled atmosphere heat treatment furnaces, zinc coating lines, and Mectron-based 100% sorting/inspection systems.
