Galvanized Steel Parts, Delivered Finished
For outdoor, wet and structural applications, hot-dip galvanizing gives decades of protection with little maintenance. We galvanize the frames, posts, brackets, platforms and structures we fabricate, and deliver them inspected and packed for site.
Galvanizing starts at the design stage. Vent and drain holes, closed sections and weld details are checked during the drawing review, so zinc can flow in and out and the part comes back straight and fully coated. Large or heavy parts are reviewed for geometry and lifting points before fabrication.

Protective Coating Options
Hot-Dip Galvanizing
Full immersion in molten zinc for frames, structures, posts and brackets. Inside and outside surfaces are protected.
- EN ISO 1461
- Parts up to 12 × 5 × 5 m
- Thickness to steel section
Zinc Plating
Electro-zinc plating for small parts, fasteners and threaded components where a thin, even coat is needed.
- Small and threaded parts
- Passivation options
- Tight tolerances kept
Duplex Systems
Galvanizing followed by paint or powder coating, for the longest life in aggressive environments or where colour matters.
- C4–C5 environments
- RAL colour over zinc
- Sweep-blasted for adhesion
What to Check on the Drawing
We review these points before quoting and suggest changes where needed.
| Topic | Why it matters |
|---|---|
| Vent and drain holes | Closed tubes and hollow sections need holes so zinc and air can flow; otherwise the part can be damaged. |
| Overlapping plates | Large overlaps trap acid and cause weeping; seal-weld or leave a gap. |
| Thickness differences | Very different wall thicknesses can cause distortion during dipping. |
| Part size and weight | The part must fit the bath with its lifting points; long parts can be double-dipped. |
| Threads and machined faces | Threads are re-tapped or masked; machined fits are specified after galvanizing. |
| Coating thickness | Set by steel thickness to EN ISO 1461 unless your specification asks for more. |
Galvanized Parts in Practice
Questions About Galvanizing
Do you galvanize the parts you fabricate?
Yes. Frames, structures, posts and brackets are fabricated, hot-dip galvanized to EN ISO 1461, inspected and packed on one order.
What is the largest part you can galvanize?
Parts up to 12 m long, 5 m wide and 5 m high fit the bath. Final limits depend on geometry, weight and lifting points; longer parts can be double-dipped.
Can galvanized parts be painted?
Yes. Duplex systems, galvanizing plus paint or powder coating, give the longest life and allow any RAL colour.
Which standard do you follow?
EN ISO 1461 by default. ASTM A123 can be applied when your specification asks for it.
Do you galvanize solar structures?
Yes. Solar tracker posts, brackets and profiles are one of our regular galvanized products.
Hot-Dip Galvanizing in Türkiye for European Projects
Hot-dip galvanizing is the standard corrosion protection for structural steel, solar structures, platforms and outdoor machinery. The steel is cleaned, fluxed and dipped in molten zinc at around 450 °C, forming a metallurgically bonded coating that protects edges, corners and inside surfaces alike.
Fabricated and galvanized on one order
Buying fabrication and galvanizing from two suppliers means two schedules, extra transport and a gap in responsibility. We fabricate, galvanize, inspect and pack on one quotation, and the same quality system covers the whole route.
Designed for zinc
Good galvanizing starts on the drawing. We check vent and drain holes, overlaps and section thickness during the drawing review, and suggest small changes that avoid distortion, ash inclusions or uncoated areas.
Solar and structural steel
Galvanized solar tracker components, posts, brackets and structural kits are a regular part of our work. Parts are bundled and packed so the coating arrives undamaged. For colour or extra protection, combine galvanizing with paint or powder coating. Send your drawing with the coating requirement.
