We like to use 3/16″ (0.180 in.) thick A588 steel for our planters for rigidity and durability over thinner metal. We pride ourselves in providing the highest quality steel planter boxes on the market.

DenverWeld corten steel planters can be made from other thicknesses ranging from 1/8″ (0.120 in.) to 3/4″ (0.750 in.). Planter boxes can also be made from other metals like regular steel, aluminum, or stainless steel, though there are many reasons corten is so popular. One of those reasons is ease of maintenance – the thick weathering steel patina is colorful, natural, and organic looking, and it does away with the need for coatings and associated coatings maintenance. Corten and steel in general is highly recyclable and contains recycled material.

Popular Styles of Steel Planters

Three of our favorite corten steel planter styles are welded (monolithic), hot-riveted, and bolt-together. DenverWeld steel planter boxes exude attention to detail, and stand above our competitors thin alternatives. We can give you quote on high-quality custom steel planter boxes made to your specifications, whether your raised planting beds are on the ground or on a rooftop.

Welded Steel Planter Boxes

Monolithic corten steel planter boxes are welded and sanded smooth for a clean, modern look and feel.

Welded steel planter boxes have a clean, trendy look. We call this one-piece, solid construction style monolithic. Monolithic raised planting beds have a massive look and feel and they are smooth to the touch. The picture to the left shows an L-shaped planter with integrated bench seating (10° slanted seat back). The welded planters are a great choice for residential packages because residences usually have many one-off parts and easy ground-level access. Commercial projects such as rooftop patio remodels and larger projects are designed differently and usually have many repeating parts that bolt together to minimize field welding.

We also custom make corten steel fire pits, water features, and other accessories to complete your landscape package. DenverWeld weathering steel landscape features are heavy duty and well suited for commercial applications as well as residential projects. We provide accurate, reliable shop drawings to our customers, showing critical measurements and features of the project. Once the design is approved by the customer, we fabricate the components in our shop and they fit just right, every time because we utilize the latest in 3D CAD, CNC Cutting, and CNC Forming technology.

Pricing is based on our shop rate of $150 per hour plus materials for design and fabrication. Yes, mass produced steel flower pots are cheaper than our custom, American made, 3/16″ thick corten steel planter boxes. Email your unique ideas or plans to sales@denverweld.com.

 Hot-Riveted Corten Steel Planters

One of our specialties is riveting. We use solid rivets, heated glowing red, that permanently join the metal parts. Hot-riveting gives decorative steel features, like planter boxes, an authentic and classic look and feel. The boxes are made from rigid steel and are as solid and durable as they look.

The pictured set of riveted planters was installed in Denver, Colorado near Cheesman Park by the DenverWeld crew. Some of the planters needed to be placed around trees. We were able to hot-rivet these boxes in the field, which was a lot of fun. The process is loud, mostly because we use an air hammer to form the rivets. Even when the rivets are red hot and soft, it still takes considerable strength to form them over. The other side of the rivet is held in place by hand with a tool called a bucking bar. The bucking bar has a die on the end that keeps the rivet from flying out of the hole when the air hammer strikes and keeps the domed head from deforming.
