About National Planter Supply
Corten Steel Products, Custom Fabrication & American Manufacturing
At National Planter Supply, we design and manufacture durable, distinctive Corten steel products for landscapes, gardens, outdoor living spaces, commercial properties, and architectural applications. Based in Pennsylvania, our team combines practical manufacturing expertise with thoughtful design to create Corten steel products that are built to perform and designed to stand out. From modular raised garden beds and landscape edging to custom planters, water features, fire features, and architectural steel elements, we specialize in turning functional ideas into beautifully finished steel products.
Our goal is simple
Create high-quality Corten steel products that look better with age, perform in demanding outdoor environments, and give our customers the flexibility to create something truly their own.
Built Around Corten Steel
Corten steel is at the heart of what we do.
Also known as weathering steel, Corten develops a naturally weathered patina when exposed to the elements. This distinctive finish gives each product a rich, evolving appearance while providing a durable material well suited for outdoor applications.
Rather than treating weathering as a flaw, Corten steel makes it part of the design. Its warm, earthy appearance can complement natural landscapes, modern architecture, traditional gardens, commercial environments, and contemporary outdoor living spaces.
At National Planter Supply, we use Corten steel to create products that bring together durability, functionality, and architectural character.
More Than Garden Beds
While our roots are in Corten steel garden products, National Planter Supply has grown into a broader source for Corten steel fabrication and outdoor products.
- Our product offerings include:
- Corten steel raised garden beds
- Modular Corten steel garden beds
- Corten steel landscape edging
- Corten steel planters
- Commercial and architectural planters
- Corten steel water features
- Corten steel fireplaces and fire features
- Custom Corten steel products
- Architectural Corten steel elements
Our modular products provide flexibility for landscape and garden projects, while our custom fabrication capabilities allow us to develop products for projects with unique dimensions, applications, or design requirements.
Designed for Landscape Professionals, Businesses & Homeowners
National Planter Supply works with a wide range of customers and project types. Our Corten steel products can be incorporated into residential landscapes, commercial properties, public spaces, gardens, restaurants, hospitality environments, corporate campuses, outdoor living areas, and architectural projects. We understand that every project has different requirements. A homeowner may be looking for a raised garden bed that becomes a focal point of the landscape, while a landscape contractor or designer may need multiple modular beds for a large installation. An architect or commercial developer may require a completely custom Corten steel element.
That is why we offer both standardized products and custom fabrication options.
Custom Corten Steel Fabrication
Have an idea that doesn't fit into a standard product? That's where our custom capabilities come in.
Our team can work with customers, landscape designers, contractors, architects, and other professionals to develop custom Corten steel products and architectural elements based on project requirements. Custom applications can include unique planters, oversized landscape elements, water features, fire features, garden structures, architectural accents, and other fabricated steel components.
We believe the best custom products begin with understanding the application. By considering dimensions, functionality, installation requirements, aesthetics, and the surrounding environment, we can help transform an idea into a finished Corten steel product.
Meet "The Man of Steel"
Elmer Fisher – The Vision Behind National Planter Supply
National Planter Supply was built from a passion for design, craftsmanship, and the possibilities of Corten steel — and at the heart of that vision is owner Elmer Fisher. Elmer brings a creative, hands-on approach to every project, with a particular appreciation for the way form and function can work together. His background in the landscape industry gives him a unique perspective on how steel products need to look, perform, and ultimately become part of the environments where they are installed. What began with a desire to create better, more distinctive planters has grown into a broader collection of Corten steel products and custom fabrication capabilities. Today, Elmer continues to be involved in developing new products, exploring creative applications for weathering steel, and finding ways to turn unique ideas into practical, beautifully crafted products.
For Elmer, the goal has never been simply to manufacture another steel product. It's about creating something that serves a purpose, stands up to the elements, and adds character to the landscape or space around it. That philosophy can be seen throughout National Planter Supply—from modular garden beds and architectural planters to custom water features, fire features, and one-of-a-kind Corten steel fabrications.
“Good design should work as beautifully as it looks.”

Why Choose National Planter Supply?
Quality Materials
We believe outdoor products should be built to withstand the environments in which they are installed. Corten steel provides the durability and distinctive appearance our customers are looking for in long-lasting outdoor applications.
Functional Design
Our products are designed with more than appearance in mind. We consider how they will be assembled, installed, used, and incorporated into the surrounding landscape or architecture.
Customization
Not every project fits a standard size or configuration. Our modular and custom fabrication capabilities provide flexibility when a project requires something different.
Built to Last
Corten steel is particularly well suited for outdoor applications because its weathering process creates a protective patina over time. The result is a product that develops its own character while remaining durable for years to come.
American Manufacturing
National Planter Supply is proud to manufacture Corten steel products in the United States. Our focus on domestic manufacturing allows us to maintain greater control over the products we produce and the quality we deliver to our customers.
Our Approach
We believe good outdoor products should accomplish three things:
They should work.
They should last.
They should look incredible doing it.
That philosophy influences everything we create. Whether we're producing a modular raised garden bed, fabricating a custom planter, developing a Corten steel water feature, or creating a one-of-a-kind outdoor fire feature, we focus on combining durability and design. The result is Corten steel that isn't simply an outdoor product—it's an intentional part of the landscape or architecture.
