Constructed with tubular steel, our fiberglass steeples are built for strength, and durability.  We carry a wide variety of architectural styles to meet any application.


Our fiberglass domes are constructed with the highest quality materials to insure our domes have the maximum strength, and durability.


These roof mounted fiberglass crosses are manufactured from high quality structural aluminum with a steel base plate. They are light weight and easy to install. Standard color is white, but custom colors are available at an additional charge.


Little Giant® carries a variety of easy to mount fiberglass finials. Finials are available in any standard color. Custom colors are also available including copper coat & patina copper coat.

Our fiberglass domes are made with specially formulated gel coats for any exterior applications.

Our low styrene extra hard gel coats maintain their color and resist hailstones.

The gel coats we use are an integral part of the laminate so it won’t crack and peel off like painted surfaces.

Our “Armor Flex” gel coats are extremely resistant to the sun’s damaging ultra-violet rays.

All of this together means decreased maintenance cost to you over the life of the dome.


 When FSI set out to design a safer fiberglass baptistry we did not want to overly increase the size of the tanks which would have required the customer to have a larger opening for installation, and require more water to fill.

In order to achieve our goal we designed each fiberglass baptistery with steps that flow into the tank area.

This allowed the maximum use of available space with minimal waste.

The result conserves water, and reduces costs associated with heating the water.

It also provides an integrated child’s step within the tank.
