Corten Steel Water Feature
Featuring a unique rust-coloured surface, our corten steel water features create a tranquil atmosphere while adding an industrial aesthetic and a sense of history to outdoor spaces.
This article provides a complete guide for maintaining your fountain, ensuring smooth water circulation, preventing algae growth, and preserving the iconic rust layer.
Essential Tools & Safety Tips for Corten Steel Water Feature Maintenance
Proper maintenance begins with the right tools and safety precautions.
Tools You'll Need:
Soft sponge or microfiber cloth – prevents scratching the oxide layer
Neutral liquid soap – safe for corten steel surfaces
Distilled water or maintenance solution – ideal for small water features
Soft-bristle toothbrush – cleans pump gaps and corners
Garden hose – for rinsing surfaces
Small vacuum cleaner or debris remover – removes sediment from larger fountains
Pet- and child-safe algae remover – protects outdoor ecosystems
Safety First:
Ensure all power to the fountain is turned off and unplugged
For large fountains, disconnect via circuit breaker
Check lighting and wiring to avoid water ingress and short circuits
Surface Cleaning of Corten Steel Fountains
The rust layer of corten steel acts as a protective barrier, so handle with care:
Use microfiber cloth dipped in warm, soapy water to wipe dust and dirt
For stubborn stains (bird droppings, decomposed leaves), gently scrub with a soft-bristle brush
Avoid steel wool or abrasive cleaners
Rinse with clean water and dry thoroughly to prevent localized over-rusting
Maintaining the Water Circulation System
The pump is the fountain's "heart" and requires regular attention:
Disassemble pump and rinse debris with a garden hose
Use toothbrush to clean intake ports and impeller gaps
Inspect cables and connections; replace damaged components promptly
Apply 1–2 drops of specialized lubricant to bearings before reinstalling (avoid edible oils)
Controlling Algae and Maintaining Water Quality
Algae growth is common in outdoor fountains, especially in hot weather:
Remove leaves, petals, and debris weekly
Apply eco-friendly algicide monthly (dosage based on water volume)
Introduce algae-eating fish in shallow areas (2–3 small fish per trough, avoid overstocking)
Water Level Adjustment to Prevent Pump Damage
Weekly check of water level; top up with distilled water or rested tap water
Large fountains can include automatic water replenishment for unattended periods
Proper water coverage prevents pump dry running and ensures optimal circulation
Seasonal Maintenance for Corten Water Features
Summer – Evaporation and Algae Prevention
Use temporary shade nets to reduce water loss and photosynthesis
Replace 1/3 of the water every 2 weeks, refill slowly along pool walls
Autumn – Leaf Fall Management
Install fine mesh nets to intercept falling leaves
Vacuum pool sediment weekly to prevent water contamination
Ensure drain outlets in troughs are unobstructed
Winter – Frost Protection
Drain fountain completely if temperatures drop below 0°C
Dry steel surface and crevices; dismantle and store pump indoors submerged in water
Cover with breathable waterproof material, leaving ventilation openings
Spring – Revival and Inspection
Remove protective cover; rinse dust from corten steel surface
Inspect for frost cracks or deformations
Test and clean pump; add water stabiliser before restarting circulation
Common Maintenance Mistakes to Avoid
Over-Cleaning the Rust Layer: Only remove dust; avoid steel wool or rust removers
Using Harsh Chemicals: Avoid bleach or toilet cleaners; for scale, use diluted vinegar (1:10) and rinse after 10 minutes
Ignoring Pump Compatibility: Select pump suitable for water volume (hourly circulation 3–5× water body volume)

How long will Corten steel water Features last outside?
Generally, Corten steel will patina or rust within six months of atmospheric exposure. Most weathering steel types need wet/dry weather cycles to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years
Is weathering steel more expensive?
Although weathering steel is slightly more expensive than ordinary structural steel, savings from elimination of the paint system offsets the additional material cost. Hence, the initial cost of a weathering steel bridge is very similar to that of a conventional painted steel alternative.
How to identify weathering steel?
till, its most recognizable feature is the development of a unique rust-like patina over time when exposed to the elements. This patina starts as an orange hue and gradually darkens to a deep brown or black, giving Corten its characteristic weathered appearance.
What is weathering steel?
Weathering steel definition: steels that are chemically formulated to develop a protective patina layer – rust-like in appearance – that eliminates the need for paint. The dense oxide patina layer of weathered steel seals it off from the atmosphere. If a weathered steel panel is scratched, its patina will self-heal.
