AHL Philosophy: ‘Retro aesthetics, lifetime durability – the art of light and shadow reflection.’ Suitable Settings: Meditation corners, minimalist gardens, terrace relaxation areas, infusing spaces with a sense of calm.
3. Tiered Rectangular Water Feature
This design comprises stacked corten steel cascade boxes, with water flowing rhythmically down each tier to create a harmoniously staggered cascading effect. Design Highlights: Particularly suited to sloping gardens, it adapts to natural topography while adding structured modernity, making the flow's cadence the rhythmic heart of the landscape. AHL Advantage: Utilises reinforced steel box construction to effortlessly bear water weight, preventing long-term deformation or leakage issues.
4. Integrated Planter-Pond Water Feature
Modern landscape design often seeks to merge plants with water. This dual-function feature seamlessly combines a corten steel water element with an integrated planting trough, accommodating both aquatic and terrestrial plants. Styling Recommendations: Opt for vertically growing plants like horsetail to create a striking contrast with the steel's rugged industrial lines, enhancing the landscape's dimensionality. Ecological Value: Provides water sources and habitat for garden wildlife such as bees and birds, enriching the courtyard ecosystem.
Constructed from solid sheets of rusted steel, this feature employs precision-cut openings to channel water evenly across the surface, creating a vertical water wall effect. The industrial aesthetic of the steel combines with flowing water and shifting light to produce a visually striking focal point with profound atmospheric appeal.
DIY-Friendly: AHL's modular metal water wall system streamlines installation. Complete with pre-configured water flow control components, it requires no specialist plumbing knowledge. Ordinary individuals can effortlessly assemble it to swiftly achieve a premium outdoor effect. Suitable Scenarios: Garden partitions, entrance feature walls, or terrace boundary areas. Serves both as decorative landscaping and provides sound insulation and zoning, adding a minimalist, sophisticated feel to spaces.
6. Corten Steel Rain Curtain Water Feature
Featuring a weathering steel trough at the top with densely spaced outlet holes, water cascades vertically in a linear pattern to create a uniform ‘rain curtain’ effect. Visitors can walk beneath the curtain, immersing themselves in the tactile sensation and soothing sound of flowing water.
Sensory Experience: The uniform white noise generated by the falling water effectively blocks external disturbances, creating an immersive tranquil space. Light filtering through the curtain produces captivating shadow effects, imbuing ordinary outdoor areas with a dreamlike quality. AHL Customisation Service: The curtain's width, height, and water outlet density can be tailored to spatial dimensions. Paired with a concealed drainage system, it ensures practicality and aesthetic appeal while adapting to diverse scenarios.
7. Weathering Steel Water Table
Blending corten rain curtain water features with functional furniture, this table incorporates a weathering steel water basin into its surface. Water circulates gently across the tabletop, with concealed overflow outlets at the edges, combining decorative appeal with practical utility.
Core Appeal: An ideal focal point for outdoor gatherings, where friends and family can converse or dine around the table. The flowing water complements the warm patina of the steel, fostering a relaxed and inviting atmosphere. Safety and Practicality Assurance: AHL employs food-grade waterproof coatings and leak-proof welding techniques to ensure stable, leak-free water flow. Rounded edges eliminate collision hazards, balancing aesthetics, safety, and functionality.
Installation Essentials for Corten Steel Water Features
To achieve a 30+ year lifespan for rusted steel waterfalls and features, professional installation is paramount. Follow these steps for successful installation:
1. Foundation and Levelling: Ensuring Long-Term Stability
Weathering steel is inherently heavy, and the added weight of flowing water increases the load significantly. Therefore, the feature must be installed on a reinforced concrete base or compacted gravel foundation to prevent displacement or subsidence over time. AHL Professional Support: We provide bespoke foundation recommendations based on feature dimensions and local soil conditions to guarantee secure installation.
2. Pump Selection: Ensuring Optimal Flow Effects
For a 1-metre-wide corten steel waterfall, select a pump with a minimum flow rate of 4,000–6,000 litres per hour. This guarantees a continuous, substantial water curtain, preventing intermittent dripping effects. AHL's Integrated Solutions: We match professional-grade pumps to custom water features of varying sizes, ensuring flow effects align with design specifications.
3. Filtration System: Protecting Equipment and Water Quality
Specialised pump sumps or fine mesh filter bags are recommended. During the initial 6-12 month rusting period of weathering steel, minute iron oxide particles naturally shed. The filtration system effectively intercepts these particles, safeguarding pump equipment while maintaining clear water quality.
Guide to Achieving the Perfect Patina on Water Features
Q: Will Corten Steel Waterfalls Rust Through Completely?
A: No. Genuine ASTM A588 steel forms a dense, stable protective layer (patina) that effectively prevents deeper corrosion. This steel is specifically designed for humid environments and can last for decades.
Q: How Should Initial “Rust Water Staining” Be Managed?
A: During the initial installation phase of garden water features, lay dark river stones such as black basalt around the base perimeter. These stones will catch and conceal the initial rust-coloured runoff, preventing staining of expensive paving surfaces.
Q: Is the Water In the Feature Safe For Local Wildlife?
A: Yes. Once the rust patina stabilises, weathering steel features become entirely non-toxic, providing safe drinking and bathing water for garden wildlife such as birds and bees.
Q: How Long Does It Take for a Corten Steel Feature to Cease Staining?
A: The “bleed” or staining period typically lasts 6-12 months, depending on local climate and frequency of water contact. Once a stable rust layer fully forms, staining will almost entirely cease.
Q: Why Does the Water In the Feature Turn Orange or Tea-Coloured?
A: This is a normal occurrence during the initial oxidation process, caused by iron oxide particles entering the water. This is harmless. You may use a fine mesh filter during the first year or change the water every few months to maintain clarity.
Q: Does a Corten Steel Water Feature Require Winter Frost Protection?
A: Yes. In climates with freezing periods, the water must be drained and the pump removed. Water expansion during freezing within the steel reservoir may cause structural deformation or damage to internal welds.
Q: Can Fish Be Kept In a Weathering Steel Pond?
A: It is advisable to wait 6-9 months until the rust patina has fully stabilised before introducing fish. During the initial rusting phase, elevated iron levels and significant pH fluctuations may cause stress to aquatic life. For sensitive species like koi, a pond liner is recommended.
Q: How Loud Is a Weathering Steel Waterfall?
A: Noise levels depend on the drop height and the surface the water strikes. A vertical curtain falling into a deep pool produces a deep ‘rumble’, while water striking pebbles creates a crisp ‘splash’. AHL's adjustable pumps allow you to customise the sound intensity to suit different scenarios.
