The appropriate surface finish depends on the location, the design, and the desired level of maintenance. Depending on the product, we offer Corten steel, stainless steel, color-coated stainless steel, or hot-dip galvanized steel.

Corten steel develops its characteristic rust-brown patina through alternating cycles of moisture and drying; for this, we use weather-resistant structural steel of grade S355J2W+N. Stainless steel offers a more understated, precision-engineered look, though it requires regular cleaning to remove deposits and adhering foreign particles.

Color-coated finishes allow for coordination with facades, paving, or other structural elements. Hot-dip galvanized steel provides cost-effective corrosion protection but has a more industrial appearance. Not every surface finish is available for every product system.

As the patina forms and develops, rust-stained water and rust particles may run off the surface. This should be taken into account during the planning stage if the item is to be placed near light-colored patio pavers, natural stone, exposed concrete, or other sensitive surfaces.

Depending on the product and the installation site, it may be advisable to provide adequate clearance, a gravel strip, a controlled drainage system, or a suitable base/stand. In the case of Corten steel planters, contact with the base must not obstruct ventilation or prevent the metal bottom from drying.

The specific installation method depends on whether the object is placed on a paved surface, in a gravel bed, or directly in the garden.

Not every planter requires a solid base. If the raised bed is placed directly on natural ground and exchange with the underlying soil is desired, an open-bottom design may be appropriate.

For placement on terraces or paved surfaces, or to allow for future relocation, we can equip TERRESTA with a water-permeable base. If a watertight base is specified, a controlled overflow system and a suitable internal coating are also required.

Therefore, factors such as the location, the underlying surface, the intended planting, drainage requirements, and the possibility of future relocation should be clarified prior to production.

A metal planter must be capable of effectively draining water. A functional drainage layer and adequately sized outlets prevent water from pooling in the root zone.

For locations exposed to direct sunlight or frost, we recommend installing root insulation panels, depending on the type of planting. Water-retention mats are also available for TERRESTA planters; these absorb water while simultaneously providing additional insulation.

The specific equipment required depends on the planter size, location, plant species, substrate, and irrigation strategy. Particularly when planting woody plants, the technical specifications of the planter should be determined in conjunction with the planting design.

ECO-LINER is designed for projects requiring a cost-effective, straightforward lawn or garden bed edging. These prefabricated metal strips come in selected dimensions; they are cut to length on-site and secured using flat-bar anchors or spot footings.

EASY-LINER is a more versatile system for project-specific pathway edging. With this system, we can tailor material, height, thickness, connections, fixings, top-edge profiles, reinforcements, corners, and curves to the specific design. We produce detailed shop drawings or CAD plans for each project.

ECO-LINER is therefore ideal for flexible adjustments made directly on-site. EASY-LINER is the right choice when defined geometries, precise sightlines, or specialized technical specifications are required.

Curved shapes are possible. However, whether a metal strip can be bent by hand directly on-site depends on the material thickness and the desired radius.

As a general rule, a 2 mm thick strip can be manually shaped to a radius of approximately one meter. For a material thickness of 3 mm, the practical radius is around three meters. Thicker metal strips generally require suitable bending tools or should be ordered pre-bent according to the plan.

For precisely defined curves, recurring radii, or long sightlines, we recommend a pre-planned EASY-LINER version. This allows curves, connections, and mounting points to be incorporated during the manufacturing process.

Path edging strips should be embedded sufficiently deep into the substrate. As a guideline, we recommend a depth of at least 100 mm, or approximately one-third of the total strip height.

Depending on the system, various fixing methods are available, such as plug-in flat-bar anchors, welded flat anchors, driven anchors, or spot foundations. The choice of fastening depends on the substrate, height, material thickness, alignment, and anticipated load.

For long, straight sections, a reinforcement profile may be required to ensure the visible top edge remains precisely aligned over the long term. Areas subject to vehicular traffic or heavy loads require specific planning regarding their structural design and foundation.

An earth-retaining wall must safely withstand horizontal soil forces and transfer them via the foundation. Consequently, the design requires information regarding wall height, layout, corners, curves, soil conditions, adjacent areas, and additional loads.

Drainage behind the wall must also be taken into account. Depending on the construction, dimpled sheeting or geotextile fabric, free-draining backfill, and a drainage pipe are used. This prevents the permanent accumulation of water behind the metal retaining wall.

The installing contractor is responsible for ensuring structural stability. If a verifiable structural analysis is required, it must be prepared on a project-specific basis, taking into account actual soil mechanics, loading conditions, and the foundation design.

MAURESTA is an ideal solution where a load-bearing wall, L-shaped retaining element, or concrete wall panel is already in place—or is to be constructed independently of the metal facing. The concrete components handle the structural load, while our MAURESTA elements provide the visible surface finish in Corten steel or stainless steel.

The cladding panels are custom-fabricated based on specific sketches and measurements. Options include straight sections, corners, curved elements, and other special shapes. The metal panels are hooked into a rail system and secured in a way that ensures no mounting screws are visible from the front.

This approach separates the structural framework from the aesthetic metal surface, making it equally suitable for retrofitting existing walls.

For individual changes in elevation, we offer SCALA single steps in various profile shapes. These steps are installed much like block steps and secured using either flat-iron anchors or point foundations, depending on the specific installation conditions.

For complete flights of stairs, we also offer prefabricated landing stairs, structural stair units, self-supporting stairs, and stringer stairs. Depending on the system, the visible tread surface can be made of metal or finished on-site with materials such as natural stone, paving, gravel, or another suitable surfacing.

For planning purposes, we specifically require details regarding the total rise, available length, desired width, number of steps, planned surface finish, and specifications for the side connections.

Yes. We can manufacture many products from the ERDE category on a project-specific basis using drawings, site measurements, or hand sketches.

Custom dimensions and special shapes are available for TERRESTA. RONDA can be produced in non-standard diameters and heights. We plan TERRA PALA, MAURESTA, EASY-LINER, and various SCALA stair systems to suit specific geometries and technical requirements.

The following information helps us provide a precise quote:

• Sketch, floor plan, or construction drawing
• Desired dimensions and heights
• Material and surface finish
• Substrate and installation conditions
• Corners, radii, and connection points
• Planned planting or load requirements
• Soil, drainage, and irrigation specifications
• Desired delivery and installation state

The more precisely the installation situation is described, the more accurately we can tailor the design, features, and scope of supply to the project.
