About AKRI 300

No bowing, leaking or collapsing

We created AKRI steel retaining walls as a flexible, modular solution to introduce planting to busy urban environments. ARUP tested and manufactured from thick recycled steel panels, AKRI is a hard wearing and robust planting solution that will withstand heavy use in public areas. Using straight panels with heights up to 1.1m, AKRI will help realise any linear shape and offers maximum flexibility to site constraints and design intent.

3mm thick recycled steel panels
2-metre long straight panels
Heights from 300mm to 1,100mm
Integrated seats, armrests, tablets

Integrate inclusivity

Add Seating, backrests, armrests and tablets

The AKRI is primarily a planter walling system, but to enhance the landscape and encourage inclusivity we have added bolt-on seating and more. All of which come in modules to suit multiple seating situations, so you can include backrests, armrests and tablets.

Seating can be retrofitted but we recommend fitting them before filling the planter for the best results.

Seating

With or without backrests

AKRI bolt-on seating comes in 4 standard modules based on seating lengths that will suit any number of seating situations – and with various armrest options available with each size, you can design your scheme or project with accessibility in mind.

1200mm
1600mm
2000mm
2400mm
Backrest sizes: 1000mm | 1400mm | 1800mm | 2200mm

As for the Timbers, we use untreated Iroko as standard but we also offer UVP treatment on request. Though we recommend specifying at the same time as the planter itself, seating can also be retrofitted giving you even more flexibility.

Armrests & Tablets

Create more accessible schemes and projects using armrests and tablets with flexibility to place them to suit various seating solutions. For armrests. we offer centre, mid & end arms in all steel or with timber tops. With our timber-topped tablets most suited to center placement.

Armrest size: 60mm
Tablet size: 290mm

These must be specified at the same time and cannot be retrofitted.

The Steelwork

Triple process Polyester Powder Coating

Unlike galvanising, our triple process coating offers smooth coverage of complex shapes and better adhesion whilst also offering the flexibility of choosing any standard RAL colour.

Corten

With its warm finish, Corten is often popular on schemes to soften the landscape; we offer this finish in a preweathered or natural state.

The Timbers

Iroko

Classification: Very Durable
Source: West Africa
Weathering: 3 months

A West African species that is rich in natural oils with a ‘Very Durable’classification, which is also relatively stable, readily available and is cost effective. Iroko is the timber that we use on the vast majority of our timber surfaced seating products, most often supplied in a smooth planed finish that will typically fade to silver-grey within 12 months.

If supplementary treatments are required to retain the original colouration for longer, the natural oils must be either allowed to dissipate through weathering over 3 months outdoors before application, or be cleansed if treatments are applied at the outset (applying a treatment directly to freshly machined timber tends to result in it sitting on the surface and not penetrating into the grain).

How It's Delivered

1. Panels & Supports

We make AKRI in the UK, which allows any scale of planter to be created with super-fast lead times. Our system is delivered flat packed with easy to follow instructions.

Using your layout, our inhouse design team will create the most optimal modules for manufacturing and installation.

2. General Arrangements

As the possibilities are near limitless, each project will have a general arrangement drawing before any manufacturing takes place to ensure all expectations are met. Each panel is marked and etched with a unique reference so that it is easy to identify on site.

3. Read to Bolt Together

Panels are supplied with welded brackets. Fins, panels and top bracket are bolted together with the supplied fixings to provide a solid connection; however the anchors to fit to the ground are not supplied. For the pedestal and tray system, we offer an additional base tray for fixing the fin.
