Cast Iron Planters

Broxap's cast iron planters are designed for commercial and public realm schemes that need a planter built to last for generations rather than a few years. Cast iron has long been the material of choice for traditional, heritage-style street furniture, and our cast iron planters carry that legacy into modern town centres, conservation areas, civic spaces and period developments where a classic aesthetic matters as much as performance.

Built for Longevity

With a potential lifespan of 100 years, cast iron planters represent one of the most durable options available for outdoor public spaces. That longevity makes them a sound long-term investment for local authorities, contractors and property owners who want street furniture that won't need replacing within a typical project lifecycle, and who'd rather avoid the ongoing cost and disruption of swapping out lower-grade planters every few years. In high-footfall areas such as town centres, retail developments and transport hubs, that resilience is particularly valuable, as cast iron stands up well to general wear, knocks and the demands of constant public use.

Construction and Finish

Each cast iron planter is constructed in grade 250 cast iron, a robust and well-established grade chosen specifically for its strength and reliability in outdoor applications. Every component is then finished with a primer undercoat followed by a 2-pack acrylic topcoat, giving the planter a durable, weather-resistant finish that holds its colour and condition far longer than standard paint systems. This finish is available in a wide range of BS or RAL colours, allowing cast iron planters to be specified to match existing street furniture, corporate branding guidelines, or the broader colour palette of a public realm scheme.

Practical detailing has also been built into the design. Each cast iron planter includes drainage holes incorporated into the base, allowing excess water to drain away freely rather than pooling around root systems. This helps protect any planting inside and reduces the risk of waterlogging, frost damage or premature deterioration, which all contributes to the planter's long service life.

Customisation for Corporate and Civic Identity

For organisations looking to make more of a statement, our cast iron planters can be customised with logos, crests or lettering. This is a popular choice for local authorities wanting to reinforce a civic identity across a town centre, heritage sites looking to incorporate historic crests or insignia, and corporate landlords or BIDs aiming to add subtle, permanent branding to a public space without resorting to signage. Because the customisation is built into the planter itself rather than applied as a sticker or temporary feature, it ages alongside the rest of the product and remains part of the design for the planter's full lifespan.

Where Cast Iron Planters Work Best

Cast iron planters are particularly well suited to schemes where a traditional or heritage character is important: conservation areas, historic town centres, period buildings, civic squares and any development looking to soften a modern setting with a classic design reference. Their weight and permanence also make them a stable, long-term fixture in public spaces, sitting comfortably alongside other heritage-style street furniture such as traditional bollards, lighting and benches.
