Pivoting Door

If you’re looking for the best pivot door system in the world, the Sing pivoting door might be just what you’re looking for. When it comes to large panels and pivoting doors nothing is better than a pivoting door with Sing Core inside.

Pivoting Front Doors

Pivoting front doors are a challenge for most pivot door manufacturers because in most cases, pivoting doors are taller, wider, and thicker than other types of front doors. Due to the size, your pivot front door is likely to be very heavy requiring expensive hardware and installation expense, as well as continuing expensive maintenance costs because the nature of this door is to fail due to warping, or stress and strain exerted on the hardware and structure if used regularly.

If your pivoting front door has Sing Core inside, you don’t have to worry about these expenses, because you are the proud owner of an Eco-friendly lightweight, high strength pivot front door that can be guaranteed not to warp or otherwise fail for 50 years!

Pivoting Metal Doors

Pivoting metal doors are making their mark by appearing more regularly in modern architecture and design channels. A metal pivot door is going to be extremely heavy and if welded will compromise high precision, this is a recipe for expensive regular maintenance over time, unless your metal pivot door has Sing Core inside.

Your perfect pivoting door would possess all the visual cues offered by the design your creativity birthed, without all the headaches, and pivoting metal doors are far more high precision based on the precision of Sing Core (+/- .006 tolerances) and the fact that inventor Peter Sing’s factory uses patented and patented-pending pivot door manufacturing processes which are welding-free.

Sing Core provides the top door manufacturers in the world with all types of metal doors. By far, the most popular metal doors are aluminum pivot doors, which is the most economical and high-performance metal which can be used in metal doors. If that’s what you’re looking for, then the aluminum pivot door with Sing Core inside might be the perfect match for you.

Next up are steel pivoting doors, which come in a variety of steels, such as cold rolled steel, galvanized steel, hot rolled steel, diamond plate steel, and quilted steel. Of all the different kinds of steel available, hot rolled steel is climbing the charts at an incredible rate, and the hot rolled steel pivot door is expected to be the number one selling custom-made modern pivoting doors soon.

Custom-made Modern Pivoting Doors

Long known for their custom-made modern architectural pivoting doors, this is the mainstay of the success of Sing Core. Inventor Peter Sing’s custom high-end pivot entry doors are featured in the most expensive multi-million-dollar homes across the United States and can even be found on the top floor of the highest building in America (the 89th floor of the Freedom Tower at the World Trade Center).

Interestingly enough, even though Sing’s Eco-friendly factory is nestled in the serene Pacific Northwest in a remote area of Washington State, most of the products are shipped out or exported, with nearly 80 percent of inventory being shipped to the greater New York-area.

Warp-free Wood Pivoting Doors

And if that wasn’t enough, inventor Peter Sing seems to have conquered the most prevalent of problems with wooden pivoting doors, which is widely known as warping. With the proprietary knowledge of non-warping technologies supported by hybrid patented and patent pending reinforced torsion box inventions, Sing’s True Flat Team is able to create a wood pivot door which can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

50-year Guarantee

It’s the only way we know of to make a large pivoting door (up to 40 ft.) that can be guaranteed to remain warp-free for 50 years, including a full structure warranty. Prior to the invention of sing Core, such a feat was just not possible, especially for a large pivoting door made of wood.

Thanks to Sing’s invention, the way large pivot doors are built is changing all over the world, and you can be counted among the many who can enjoy the sense of peace which comes from owning a pivoting door with Sing Core inside, helping to make the world a better place one door at a time.

Oversize Entrance Pivot Doors

“If we could build this giant warp-free wooden pivot entry door, we can build your door.” ~ Peter Sing

For thousands of years pivot doors have been the upscale preference of the most exotic high-end large oversize entrance doors relying heavily on the entry door hardware, specifically the pivot hinge, to manage the functionality of the pivot door.

Due to the size and weight of the conventional modern pivot door the heavy duty hinges and pivot door hardware could account for up to half the cost of the pivot door (e.g., a low end pivot door could cost $3,000, half the price will pay for the hardware due to the heavy weight), creating a high price point as well as being expensive to transport, handle and install.

Yet, the most demanding clients desire this elegant outswing exterior door to make an extreme visual impact for the primary access point of their structure (while bringing the outside in and the inside out by way of the architect’s modern design concept) regardless of price to command attention via first impression.

Pivot doors may be the most expensive designer doors but there’s no escaping the luxurious feel that they lend to designs by top architects who help to create the most leading edge structure designs by featuring the best exterior doors.

Since hardware is of huge importance in a pivot door’s design and implementation, there are many options to consider including offset pivot hinge, commercial door hinges, heavy duty door hinges and center pivot door hardware in your pivoting door system.

Steel Pivot Doors

Many pivot doors feature metal structures and framed composites and more popular for exclusive high security environments, commercial steel entry doors and even residential steel entry doors.

How to Build an Exterior Door

Many considerations must go into the design, plan, building and installing a pivot door.

1. The Core Material
The core material that makes up the heart of your pivot door determines so much. Based on your choice of material you will determine your pivoting door’s:

  • Weight
  • Strength
  • Insulation
  • Precision
  • Performance
  • Maintenance

2. The Frame

Will your pivot door be a solid one-piece material construction, or will it be framed or unframed?

Many options about for the substance of your pivot door, first – the most heavy and likely the most unstable – is solid construction, then framing. Framing your pivot door can be with wood or metal, like steel or extruded aluminum. Wood will move framing with metals, like a conventional steel door, may not meet high performance specifications due to welding creating imperfections in the metals.

3. The Entry Door Styles

What will the general appearance of your door be? What exterior surface material, skin (see material options) or design will make your pivot front door stand out to make that impactful visual impression?

5. Installation

Who will install your pivot door and will any special handling/equipment be required for installation?

Can the Affordable Pivot Door Replace Contemporary Entrance Doors?

Until now, pivot doors have generally been too expensive for the average homeowner to consider, but one pivot door core material is changing all that. Sing Core manufactures an Eco-friendly pivot door core material used by the most high-end architects, designers, door manufacturers, millworks and contractors for building the best pivot doors in the world.

What constitutes the best pivot door in the world? One that is:

1. Eco-friendly (sustainable, true green)

Sing Core panels are constructed with natural wood fiber vertical grain torsion box filled with recycled rigid foam adhered between stress skins using formaldehyde-free glue for a solid substrate.

2. Lightweight

Sing Core panels weigh a fraction of the weight of other solid structural building materials.

3. High strength

Sing Core panels were independently tested by the University of Washington at 660 PSI for super-strength (compared to 10 to 110 PSI of other honeycomb cores used in the aerospace industry).

4. Insulated

Sing Core panels are packed with insulation rated at R 3.5 to R 6.5 (depending on foam selection) and feature sound deadening qualities for security and privacy.

5. High Precision

Only Sing Core panels can be created to be true flat, within .006 inch tolerance with little or no deflection.

6. Versatile

Sing Core panels can feature any surface material (skin), like any wood species, aluminum, ceramic, concrete, fiberglass (FRP), HPL, Kevlar, LVL, MDF, stainless steel, stone or any other flat building material, may host any glass lite openings in any configuration and can be embellished to have the appearance of any style door imaginable.

How Can I Get a Sing Core Pivot Door?

There are many ways that you can make your pivot door dreams come true.

1 Architect

Architects have access to Sing Core technology and are specifying Sing Core in their pivot door designs – especially if they are large pivot doors – that can be manufactured by their favorite millworks.

2 Millworks

Most one-of-a-kind custom pivot doors are created by revered craftspeople and woodworkers who create hand crafted pivot doors for exclusive clientele.

3 Door Companies

Any door company can use Sing Core panel as the substrate for your pivot door. Though many do not feature the Sing Core pivot door as a standards catalog item, in most cases you can special order your pivot door with Sing Core technology.

4 Contractor

Sing Core pivot doors panels are sold without hardware installed and unfinished. Our door panels are manufactured for mill works to install hardware and finish. We do not recommend shipping Sing Core door panels the job site for installing hardware and finishing. This is not the best way to treat a high end door such as a large pivot door made with Sing Core. We highly recommend the GC work with millwork professionals to finish at their facility (except some special restrictions).

We believe each professional has it’s own specialized knowledge just like we do not expect an architect to install the door, instead using a highly trained GC.

Since the weight of your Sing Core pivot door will be a fraction the weight of a solid (or framed) pivot door you can save cash that would have to be invested in heavy duty pivot door hardware that could account for half the cost of any other pivot door.

Plus you save on transportation and installation costs, just like our clients (see clients list) and enjoy maintenance-free high performance of your pivot door.
