PalmSHIELD– Features and Benefits:
- Thicker framing materials provides for larger weld able surfaces for the attachment of louvers.
- Thicker louver materials and steeper sloping of louvers within the panel provides less visibility and increased air flow.
- Larger and thicker posting materials provide better resistance from wind and snow loading.
- Solid continuous framing supports louvers independently from posts to keep panels from deflecting and warping.
- Thicker crossbar materials support louvers better between vertical frameworks.
- Custom colors available.
- PalmSHIELD is produced locally, in Kansas City, Kansas; Wichita, Kansas; Des Moines, Iowa; Iowa City, Iowa; Sioux City, Iowa; Omaha, Nebraska; Grand Island, Nebraska; Lincoln, Nebraska; Sioux Falls, South Dakota; and Rochester, Minnesota.
PalmSHIELD – Aluminum Louvered Screening
Why select PalmSHIELD for your next screen, fence or gate project?
PalmSHIELD louvered screening and grill system is perfect for providing excellent ventilation while keeping items out of sight from others. Using the industries’ only picture frame design, each panel is rigid enough to provide total security from intruders. Maintaining a consistent design throughout the system, PalmSHIELD can be configured as a series of grills, swing gates and even sliding gates.
PalmSHIELD is custom fabricated to each application, allowing end users to select the amount of visibility and air flow by varying louver spacing. Louvers may be placed vertically, horizontally or even diagonally.
PalmSHIELD is unique in providing the industries’ widest louver. Each louver is .1250 thick with an installed profile of 2” x 2.873” tall. Not only is the Palm Shield a larger profile but the entire profile is sloped providing less visibility and better air flow.
Only PalmSHIELD uses a 3” x 3” x ¼” angle vertical support system. Each louver is welded to the vertical supports. Because of the larger vertical support, PalmSHIELD provides a 2 ¾” weld-able surface to attach louver to frame.
What makes PalmSHIELD the very best louvered system is the use of a 3” x 3” x ¼” angle top and bottom cap. Most systems do not provide a top and bottom cap system. A top cap is critical in protecting the panel from falling debris, hail, etc. while the bottom cap protects the louvers from foot traffic and mowers.
The vertical supports and horizontal caps are welded together to form the industries’ only picture frame design. This design provides a rigid framework to support the louvers from twisting and warping also making it easy to remove and reinstall if necessary.
PalmSHIELD uses a 2” x 1/8” aluminum flat bar not to exceed 24” apart to support the louvers between the framework. This support prevents intruders from attempting to spread the louvers apart to gain access.
Larger than most systems, PalmSHIELD uses a 4” square x ¼” wall post. The larger and thicker walled post is suited for high wind and snow loads. Posts are not to exceed 60” inches on center.
All nuts, bolts and fasteners are stainless steel. If gates are incorporated into your system, only stainless steel hinges will be allowed.
PalmSHIELD uses sheet aluminum in accordance with ASTM B 209 6063 – T6 and extruded aluminum in accordance with ASTM B 221 60603 – T6.
After fabrication is completed, all materials are carefully sweep blasted and powder coated. Custom colors are available. PalmSHIELD uses polyester powder coating in accordance with material hardness ASTM 3363 2H.

Any louvered screen will increase the wind load on it supporting structure. This has traditionally been an educated guess with a considerable safety factor. However, most architectural louvered screens are attached to adjoining walls and buildings that must meet an even greater wind load coefficient for solid surfaces.
Though PalmSHIELD may be installed as a wall louver where the louvered panels are installed like windows and attached to the building structure; PalmSHIELD louvers has its own independent structure that classifies it as a standalone louvered equipment screen system. It’s this independent structure that carries the load of assuring the overall system meets the latest IBC and UBC codes.
PalmSHIELD has been designed and engineered to meet these codes. Through measured calculations, PalmSHIELD’ s louvered panels with an 80% opening has a horizontal load of 19 psf. This wind load calculation is based on 100 mph winds which complies with the 30psf load requirement on solid building surfaces.
This load calculation is then used in calculating the design of the structural post system that supports the panels. From this calculation, we can determine post design, material selection and post spacing. By applying this load to the square footage of the panel size; we can properly estimate these specifications on a per case basis. It must be stated that these are only estimated loads because loading will vary exponentially based on the height of the panels. Not all wind loading is equal top to bottom of the louvered panel. For actual engineered calculations, each system must be independently engineered by a registered engineer within the jurisdiction it will be installed. This level of engineering is not included in the standard PalmSHIELD quote. If local stamped engineering is required for your system, please indicate so at time of quote. We will contact a local engineer in the respective jurisdiction and work directly with them to provide the necessary calculations.
What is important to recognize is that PalmSHIELD is just not another louvered screen system manufacturer. We design each system with the customer in mind.
