GrillSymbol, Ulla XL, Corten Steel Planter for Modern Outdoor Spaces

Description

GrillSymbol Corten Steel Planter Ulla XL 🌿

Add timeless Scandinavian style and natural warmth to your garden, patio, or terrace with the GrillSymbol Ulla XL planter. Designed by Petteri Wiimaa, this premium Cor Ten steel planter combines minimalist design with durable outdoor performance, creating a stunning focal point for modern outdoor living spaces.

With its clean cubic shape and elevated design, the Ulla XL brings structure and sophistication to any setting. Whether filled with ornamental grasses, small trees, evergreen shrubs, or colourful seasonal flowers, this elegant planter enhances both contemporary and traditional landscapes with ease.

Crafted from high quality Cor Ten steel, the planter gradually develops a rich reddish brown patina when exposed to outdoor weather conditions. This evolving finish not only creates a distinctive rustic appearance but also forms a protective layer that helps preserve the steel for years to come. The result is a weather resistant, maintenance free planter designed for permanent outdoor use.

The removable legs give the Ulla XL a beautifully elevated appearance while improving drainage and adding versatility to suit different outdoor styling preferences.

🌿 Design & Materials

The Ulla XL planter features a bold geometric silhouette that works beautifully in luxury gardens, rooftop terraces, outdoor kitchens, entranceways, and stylish commercial spaces.

Made from durable 3 mm Cor Ten steel, this planter is built to withstand harsh outdoor conditions while naturally ageing into a characterful statement piece. Over time, the steel surface deepens into darker earthy tones that complement greenery and natural surroundings perfectly.

Its elevated profile makes planting easier while adding a refined architectural touch to patios and outdoor entertaining areas.

Perfect for:

• Modern gardens

🔥 Built for Outdoor Living

Unlike painted planters that may crack or fade over time, Cor Ten steel naturally forms a protective weather-resistant surface layer. This makes the Ulla XL exceptionally durable and ideal for outdoor use in all seasons.

Drain holes in the base help prevent standing water and support healthy root growth, while the sturdy steel construction provides excellent stability for larger planting displays.

The removable legs allow you to customise the look depending on your outdoor design style, making the planter equally suited to modern and industrial inspired settings.
