Balcony & terrace
Wrought-iron balcony and terrace guardrail, galvanized
Made-to-order wrought-iron balcony or terrace guardrail, hot-dip galvanized then powder-coated to withstand the weather, compliant with the NF P01-012 standard.
NF P01-012 standard
The rules that apply outdoors
An outdoor guardrail must meet the same dimensional requirements as a stair guardrail, with direct weather exposure to plan for from the fabrication stage.
1m (0.80m if the element is over 50cm thick)
Minimum height
Required once the fall height exceeds 1m or the slope exceeds 45°
Trigger threshold
≤ 11cm over the full height
Vertical spacing (balusters)
< 11cm
Horizontal spacing, anti-climb zone (0–45cm)
Outdoor protection
Galvanizing and powder coating
Hot-dip galvanizing
Immersion in a molten zinc bath (NF EN ISO 1461): the zinc layer protects the steel from corrosion for decades, well before any surface finish.
Powder coating
Oven-cured powder paint, applied over galvanized steel — holds colour and resists UV, without replacing the zinc's anti-corrosion protection.
Outdoor fixing
Stainless or galvanized-steel baseplate on slab/facade, or chemical anchoring depending on the support — always designed for weather exposure.
Fabrication
Galvanized before powder coating
Every piece destined for the outdoors passes through a molten zinc bath before being shaped into its final finish — a step that doesn't show once the guardrail is installed, but that determines how well it stands up to the weather.
For comparison
Wrought iron or decorative cast-iron panels
Some panels sold under names evoking "wrought iron" are actually cast moulded iron, not hand-forged wrought iron — a difference in material and process, not just price. Panels of this type (around 1450 × 480 mm) are found around 400 €, and models presented as "period" (around 900 × 750 mm) around 390 € on promotion.
Frequently asked questions
What we're asked most often
What height does a balcony or terrace guardrail need?
1m minimum. It can drop to 0.80m only if the guardrail itself is a massive element over 50cm thick (e.g. an integrated planter) — a rare case for a classic wrought-iron guardrail.
Why galvanize before powder-coating?
Powder coating alone protects colour and appearance, not the metal's durable corrosion resistance. Hot-dip galvanizing (NF EN ISO 1461) gives a zinc layer whose lifespan is measured in decades, with powder coating then added as a finish and extra protection.
My balcony is high up in an older building, does that change anything?
The fixing (baseplate, anchoring) must suit the existing support (concrete slab, old masonry) — checked at the quote stage, possibly with a site visit.
Can an ornate pattern (scrollwork) be added to a balcony guardrail?
Yes — the regulatory dimensions (height, spacing) stay the same, only the forging time and therefore the price increase for a more ornate pattern.
Is a ground-level terrace guardrail required?
Protection is only required once the fall height exceeds 1m (or the slope 45°) — a level terrace with no significant drop generally isn't affected. Check your exact site layout.
