We've been manufacturing window grilles since 1978.  Our experience helps us to ensure an exceptional product, engineered to perfection.  At FrontLine, we pay special attention to every detail of the grilles we manufacture, assuring you a quality and lasting product.  Our friendly, knowledgeable staff, including engineering support, is here to work with you from bid to installation to ensure your project succeeds. 


We have an extensive offering of aluminum profiles to meet your needs. If you need to precisely match an existing profile, we can have dies created and extruded to specification. We can also work with your material, saving you additional costs.Our standard dies are engineered for structural durability without causing excessive weight.


We use 3M™ VHB tape as standard offering on our Simulated Divided Lite (SDL) grilles. Other fastening options may be used; let us review your project to see how we can help.


Our multitude of colors are offered in finishes meeting AAMA standards in 2603, 2604, or 2605, available in wet or powder application. Need a custom color matched? No problem! We can have any color matched to specification. We also provide anodized finishes for lasting beauty.


We can produce grille patterns that others can’t. Whether you need diamond, radius, or even a simulated vent pattern, we can achieve the look you need. At FrontLine, custom is customary!


We use a closed halving joint (“dado”) to provide a beautiful, finished look. If we are unable to dado a particular profile, we will cope the ends to perfectly match the adjoining bar or window bead.


Grilles can be shipped either assembled or unassembled, allowing you to manage your budget. By choosing to have your grilles shipped assembled, they will arrive “ready to apply.” Or, have them shipped unassembled whenever possible to save on shipping costs. Either way, your grilles will arrive completely wrapped, packaged and labeled per your order instructions.


We can ship your grilles either to your shop or direct to the jobsite.

Whether new construction or historical renovation, FrontLine delivers the right product for your project.
