FAQ
- What is the fire rating of your architectural elements?
Our systems are manufactured using fire-retardant (FR) grade EPS cores. When fully encapsulated in our proprietary polyurea hard coat, these elements are engineered to meet ASTM E84 Class A requirements for flame spread and smoke development.
- What is the typical lead time for custom production?
Standard production cycles typically range from 15 to 30 business days depending on the complexity of the geometry. We also offer priority scheduling for high-stakes projects that require expedited turnaround times to meet strict site deadlines.
- Can these elements withstand high wind loads and hurricanes?
Yes, our products are engineered for Florida-proof durability. We calculate specific wind loads for each project and can integrate internal structural reinforcements, such as 4×4 wood beams or PVC piping, to ensure stability in extreme weather zones.
- Can you match existing textures or historical masonry finishes?
Our artisans specialize in high-fidelity faux finishes. We can precisely replicate the texture and color of limestone, coral stone, aged brick, or wood, ensuring that new elements integrate seamlessly with the existing architectural context.
- Do you offer nationwide delivery and logistics support?
We coordinate secure logistics across all 50 states from our facility in Jacksonville. Every order is packed in custom-engineered crates and includes detailed marking systems to streamline the offloading and sorting process on your jobsite.
- Is additional structural reinforcement required for installation?
The primary benefit of our technology is the 90% weight reduction compared to cast stone. This eliminates the need for heavy-duty structural steel, footings, or cranes, allowing you to add grand architectural details without over-engineering the building’s frame.
- What are the long-term maintenance requirements for polyurea coatings?
Maintenance is nearly zero compared to traditional materials. Our polyurea-encapsulated elements do not rot, crack, or support mold growth. A simple periodic cleaning with mild soap and water is all that is required to preserve the aesthetic integrity for decades.
- Can you work directly from our architectural blueprints or CAD files?
We integrate seamlessly with your professional workflow. Our engineering team utilizes your CAD files or Revit models to create precise production drawings, ensuring that every arch and keystone fits your building’s specific geometry with millimeter accuracy.

Decorative Architectural Shapes Exterior Corbels and Brackets: Lightweight Detail, Strong Architectural Presence
Exterior corbels and brackets are small architectural elements with a large visual effect. They add depth, shadow, proportion, and character to the outside of a building.
Decorative Architectural Shapes Architectural Columns, Capitals & Bases
Columns have represented strength, elegance, balance, and prestige for centuries. From classical architecture to today’s luxury homes, hotels, churches, resorts, and commercial buildings, columns continue to play a major role in creating beautiful architectural spaces.
Who we are - Decorative Architectural Shapes
Decorative architectural Shapes is a US-based manufacturer of decorative architectural elements made from engineered foam, with more than 25 years of experience in the American market.
We:
- design and manufacture decorative architectural shapes at our own facility
- work with any level of complexity – from standard profiles to unique one-of-a-kind forms
- provide a 20-year warranty on every element
- deliver products fully assembled and painted, ready for installation
- support our clients from the first sketches to the final shipment
We are chosen by architects, developers, contractors, designers and integrators who care about precise drawings, predictable timelines, zero on-site rework and real savings over the full lifecycle of a project.
What we produce
At the core of our offer is a comprehensive architectural shapes catalog that covers most façade and interior design needs and allows you to plug in custom solutions without being limited by geometry.
We manufacture:
- Architectural pillars and modern decorative columns in different heights and diameters.
- Single architectural arcade elements and complex systems of architectural arcades for facades and galleries.
- Architectural fence elements and complete architectural fence systems.
- Architectural balustrades for terraces, balconies and staircases.
- A full line of decorative architectural shapes: cornices, mouldings, pediments, capitals, decorative panels, and purely decorative shutters and louvers.
- Fully bespoke custom decorative architectural foam shapes based on your drawings, 3D models or even hand sketches.
At the same time, we do not lock you into only what is in stock. Architectural design shapes are created to match the architectural language of your project: from strict minimalism and modern to detailed neoclassic.
Architectural modern decorative columns
Our architectural pillars are produced from foam with a density of 2–3 lb/ft³ and a reinforced coating. This allows us to make columns that look massive and solid, yet remain light and safe for the building structure.
Technical specifications
- Column heights can range from 6 to 24 feet.
- We offer diameters from 8 to 36 inches.
- Dimensional tolerances are up to 1/32 inch.
- The weight of foam columns is one of their key advantages — they are 7–8 times lighter than comparable concrete or stone options.
- Columns can be supplied as full modules or, if the height or diameter is especially large, as sectional components that are pre-bonded at the factory whenever logistics and transportation conditions allow.
For exteriors in the Romanesque architectural style, we create modern columns with clean lines and precise fluting. We can also match the exact color and tone required for your project, including reproducing the texture of the existing façade finish, so the columns do not appear as stand-alone architectural elements but instead become a natural, integrated part of the existing architectural environment.
Architectural exterior arcades
Arcades are where architecture becomes very sensitive to precision. Even a small error in radius or alignment becomes obvious from a distance.
Our architectural blind arcades and every individual architectural arcade segment are produced on CNC equipment using 3D models. We:
- create radii up to 22 ft;
- keep level variations within 1/16 inch across the entire span;
- integrate complex profiles, capitals and keystones into a single coherent form;
- pre-plan segmentation into transport modules to reduce risk and simplify logistics.
On a coastal project near Sarasota, the architect was looking for the best architectural blind arcades in gothic architecture style for a high-humidity, salt-air environment. Traditional stone arches in gothic architectural tradition would bring risks of cracking and high maintenance.
We produced a series of modern architectural blind arcade elements with a finish mimicking natural limestone – soft matte sheen, micro-relief, and convincing shadow play. Several seasons later the owner returned for additional elements: the arcades held their appearance with no visible aging or discoloration.
Architectural fences
Architectural fence systems in the Romanesque style, made from foam, solve several problems at once: visual zoning, safety, consistent façade language, and reduced structural load.
Key advantages:
- 4–6 times lighter than traditional concrete or masonry fencing;
- resistant to moisture and UV radiation;
- no corrosion, no rot, no cracking;
- profiles can be matched to existing façade elements;
- supplied as ready-to-install sections, already painted to your color standard.
Architectural balustrades in architectural design
Balustrades sit right at the intersection of safety, aesthetics and everyday use. Our architectural balustrades provide a classical, substantial look without the typical problems of heavy materials.
We pay special attention to proportions: balustrades in architectural design must follow classical rules, or the entire composition feels cheaper, regardless of the project budget.
Custom decorative architectural foam shapes
This is where real design freedom begins. Custom decorative architectural foam shapes allow the architectural concept to lead, instead of being trimmed down to fit a limited catalog.
We create:
- complex cornices and bands with multiple radii;
- decorative panels with wood, stone or metal textures;
- gable elements, window surrounds, pediments and crowns;
- decorative louvers and shutters that are purely aesthetic (they do not open, are not used for ventilation, and require no hardware maintenance);
- non-standard architectural design shapes for branded façades, themed environments, and both temporary and permanent installations
Every element is delivered fully painted and does not need additional finishing on site.
Materials and technologies
Our solutions are based on high-density foam with a closed-cell structure. On top of this sits a reinforced coating made from mineral and polymer components, then a protective and decorative finish.
Density and structural behavior
We use foam in the 2–3 lb/ft³ density range.
- at 2 lb/ft³, the material remains very light, ideal for large-format shapes
- at 3 lb/ft³, it gains increased impact resistance for high-traffic zones
Compressive strength typically exceeds 25–30 psi, and impact resistance is sufficient to handle everyday knocks without chips or cracks in the coating.
- Reinforced coating.
- Water and UV resistance.
- Geometry and quality control.
- Logistics and large elements.
We design each piece with logistics in mind. Elements are segmented into transportable modules and, where possible, pre-bonded at the factory so crews receive larger ready sections instead of dozens of small parts. While we do not perform installation, we work closely with transportation partners and organize shipping of even very large columns, arcades and fence elements throughout the US.

Where our products are used
Multifamily residential complexes and living communities
This includes apartment developments, townhome neighborhoods, and gated residential properties that must balance budget, aesthetics, and long-term durability. Our exterior columns, cornices, architectural fences, and balustrades make it possible to achieve a premium, high-end appearance while staying within the planned budget and ensuring long-lasting performance with minimal maintenance.
The hospitality sector — hotels, resorts, country clubs, and more
Hotels and resorts depend heavily on first impressions and on keeping downtime to a minimum. Our architectural elements — including balustrades, arcades, and custom-shaped components — allow you to refresh façades and entry areas quickly, without having to close commercial buildings for long periods, helping maintain normal operational flow.
Commercial business properties, retail environments, and office buildings.
Retail façades, storefronts, and office centers often need to stand out in dense urban surroundings. Architectural foam shapes make it possible to create the most unique, expressive, and unconventional forms — from custom logos and standout features to brand-driven profiles in cornices and panels. This allows you to build fully customized spaces aligned with the brand book, visual language, and identity of the company.
Themed spaces and exhibition environments.
Here, durability is essential, since the same architectural elements are often assembled and disassembled repeatedly. Foam structures can be designed as modular systems that are quick to put together and take apart. And the creative freedom foam provides — the ability to design absolutely any shape, even the most unconventional — is a major advantage for this type of client.
Renovation and adaptive reuse of buildings.
Architectural foam offers important benefits here, as it allows you to recreate any texture, tone, or finish — aged wood, weathered copper, traditional ornamental details, and more. This makes renovations visually seamless, while adding no significant weight to the building’s structure — a critical factor, especially in historic architecture.
In renovation projects, you often cannot increase loads on existing structures but still need to preserve or even amplify the architectural character. Light architectural pillars, cornices and balustrades from foam allow you to add expressive elements where stone or concrete would be impossible.
