Metalwork guide: railings, steel doors and structural steel

Stair railings, balcony ironwork, steel doors and structural steel — what to know about material, measurement, coating and installation.

· Demgirişim

Metalwork covers everything from railings and wrought iron to steel doors, pergolas and structural steel. Because it is both a safety element and a visual one, it demands accurate measurement, the right material and proper surface protection.

What does metalwork cover?

  • Stair railings: interior stairs, duplex apartments and communal areas
  • Balcony and terrace railings: wrought iron, vertical bar or glass combinations
  • Wrought iron: doors, windows, garden gates and decorative panels
  • Steel doors: apartment entrance doors, building doors
  • Structural steel: roofs, mezzanines, pergolas, canopies, stair stringers
  • Window grilles: ground-floor security bars

Safety rules for railings

A railing is a safety element before it is decorative. Residential standards cover minimum height, spacing between balusters (child safety) and the use of horizontal elements. In homes with small children, avoiding horizontal bar designs reduces the risk of climbing. How the fixings are anchored — into concrete or steel — determines the load capacity.

Material options

MaterialKey propertyTypical use
Mild steel (box section, flat bar)Economical, easy to shapeRailings, doors, structures
Wrought ironDecorative, classic lookBalconies, garden gates
Stainless steelMaintenance free, modernStaircases, glass railing posts
AluminiumLight, rust freeBalcony railings, pergolas

Outdoors, stainless steel and aluminium offer a maintenance advantage; with mild steel, surface protection is the deciding factor.

Surface protection: paint or powder coating?

Anti-rust primer plus topcoat: can be applied on site and is easy to touch up; durability depends on the quality of application.

Electrostatic powder coating: oven-cured for a uniform, durable finish; parts are coated in the workshop and are difficult to repair on site.

Hot-dip galvanising: the longest-lasting protection for outdoor structures; powder coating can also be applied over it.

What to look for in a steel door

Sheet thickness of the frame and leaf, lock class, number of hinges, insulation filling and how the frame is fixed to the wall all determine security. The door should be installed after the walls are built but before plaster and paint are finished, so the frame surround can be closed neatly.

How the process works

  1. On-site measurement and design approval
  2. Workshop fabrication (cutting, welding, grinding)
  3. Surface preparation and paint or powder coating
  4. On-site installation and anchoring
  5. Final inspection and cleaning

Railings are usually installed after the floor covering is complete, just before the final paint touch-ups.

Demgirişim handles metalwork from measurement to installation with its own team, and plans stair and balcony railings at the design stage of turnkey projects.

Frequently asked questions

Is wrought iron the same as metalwork?

Wrought iron refers to decorative work made from forged and bent steel; metalwork is the broader term covering railings, doors, windows and structural steel.

Will steel railings rust?

With proper surface preparation and an anti-rust primer plus topcoat — or electrostatic powder coating — the risk is greatly reduced. Periodic maintenance is recommended outdoors.

What height should a railing be?

There are minimum height and baluster spacing standards for safety on residential balconies and staircases; designs are prepared to meet these values.
