At Allé Designs, our planters aren’t just about enhancing spaces—they’re built to last with precision, strength, and environmental resilience in mind. Whether placed in bustling urban environments or serene outdoor settings, our planters maintain their structural integrity and aesthetic appeal over time, thanks to their superior materials and construction.

Material Strength

Our planters are crafted using reinforced thermosetting polyester resin, employing hand-layup and spray layup methods to ensure a sturdy, durable finish. This choice of material ensures that each planter can withstand varying environmental conditions, from intense sun exposure to extreme weather fluctuations.

Key specifications include:

  • Reinforced Fibers: We use PPG or equivalent fibers, applying a minimum of three layers to ensure long-lasting durability.
  • Solid Resin Construction: Unlike other products that may use inorganic fillers, our planters are fabricated from 100% resin, ensuring consistency and superior quality across the board.
  • UV-Stabilized and Colorfast: The gel-coat surface is not only aesthetically pleasing but also resistant to fading, stains, and the elements. This ensures that the color and texture remain vibrant and uniform for years.

Structural Integrity

Our planters are more than just aesthetically pleasing—they’re engineered for strength:

  • Thick Plastic Walls: The plastic material is no less than 5/32″ thick, and we reinforce areas requiring additional structural strength.
  • Honeycomb Reinforcement: Vertical surfaces benefit from an inorganic honeycomb layer, which enhances the planter’s rigidity. This honeycomb structure ensures walls remain stable even when supporting heavy soil and plants.
  • Marine-Grade Support: For larger planters or areas requiring extra reinforcement, marine-grade plywood can be incorporated to provide additional support without compromising the aesthetic.

Performance and Capacity

Every planter is designed and tested to meet rigorous performance standards, ensuring they handle weight, pressure, and environmental wear without compromising structure or appearance. Our planters deliver the following performance characteristics:

  • Tensile Strength: 12,500 psi
  • Flexural Yield Strength: 27,600 psi
  • Compressive Yield Strength: 21,800 psi
  • Hardness (Barcol): 50
  • Glass Content: 35%

These specifications ensure our planters can handle heavy soil loads without deforming. In fact, vertical wall panels resist deformation even under the weight of 50 lbs./cu. ft. of soil mass, maintaining their shape and beauty in the long term.


By combining the best materials, meticulous craftsmanship, and a focus on performance, Allé Designs planters are engineered for longevity, making them a perfect fit for any project where aesthetics and durability go hand-in-hand.
