You also have the satisfaction of knowing that all Eco-friendly Sing Core is manufactured in the USA made with responsible use of natural materials and recycled products for the most sustainable lightweight high-strength large pivot doors in the world.


Our doors are specifically made to deal with common problems that inferior pivot doors have. Large Pivot Doors are engineered to be high strength with little to no additional support. In fact, Large Pivot Doors have been independently tested to withstand forces of over 660 PSI. This makes our doors stronger than steel!

In the picture to the left you can see SingCore founder, Peter Sing, demonstrating the strength of our doors in comparison to traditional door materials.


Not only do Large Pivot Doors give consumers a high strength product, but our doors are lighter than traditional building materials. Our doors are typically 1/3 the weight of solid wood doors of the same size. This makes using Large Pivot Doors easier, safer, and cheaper.

50 Year Guarantee

We are so confident in our product that we have a 50-year guarantee that our doors will not warp, bend, twist, or otherwise fail. No other pivot door company in the world guarantees this but Large Pivot Doors.
