The Best Metal Doors

Metal doors offer many advantages over other types of doors and are commonly featured as metal security doors, in commercial, industrial, institutional, and health care fields. You want the best metal doors because all kinds of metal doors can present problems throughout the manufacturing, installation, and maintenance of a metal door’s life.

Of all the metal doors available in the marketplace today, steel doors are the most common, followed by stainless steel doors, aluminum doors, brass doors, bronze doors, cold rolled steel doors, hot rolled steel doors, Galvannealed steel doors, and galvanized steel doors.

Steel Doors

Steel doors steal the show when it comes to metal doors. Steel front doors are by far the most popular of all steel door applications. Heavy duty steel security doors are sought out for the obvious reasons to enhance safety and security for important personnel or high-risk environments.

 

 

Commercial Steel Doors

The most prevalent commercial metal doors are custom steel doors created to serve as a metal door in a clean room, protection from extreme weather conditions, coolers and freezers. Or to fill large openings in loading docks, warehouses, parking garages, nautical and aircraft hangers.

Because metal doors are so heavy, leading to increased care and maintenance, hollow metal doors are becoming more commonplace as they are less expensive and are virtually dispensable. Rather than fixing or repairing hollow metal door, they are easy enough to simply discard and replace them with another inexpensive hollow steel door.

Government installations use metal steel doors, but its not enough to just have a door made of metal, they have greater expectations in terms of high-precision and high-performance. The most distinguishing users of metal doors are seeking out manufacturers of steel doors which can deliver better precision and performance. Architects, designers, engineers, and custom metal door manufacturers are on the lookout for the best steel doors.

Sing Core delivers insulation options throughout metal doors to provide added safety and security, which provide the end user benefits which can be demonstrated as sound-deadening and increased climate control characteristics. Sing Core is often featured inside the most effective sound proof metal doors and refrigeration metal doors capitalizing on the high insulation value of having Sing Core inside.

Low Maintenance Steel Doors

Metal doors with Sing Core inside are the most comprehensive of all doors when it comes to reducing maintenance costs over time. For instance, metal doors will mainly fail due to warp or deterioration over time. Unless you’re using disposable metal doors, you will be faced with regular maintenance issues, unless your metal doors have Sing Core inside.

Imagine having a metal door which requires very little maintenance over time. Metal doors with Sing Core inside are covered by the only known comprehensive 50-year guarantee in the industry. The guarantee covers everything from door warp to the door’s structure for fifty years. We know of no other door manufacturer which guarantees their doors to remain warp-free for 50 years, including the structure of the door over time.

Eco-friendly Steel Doors

For years, Sing Core has been the most earth-friendly way to manufacture high precision doors in a safe, sane, and earth-friendly manner, often touted as the most sustainable over time. The expected life of a metal door with Sing Core inside is 100 years, though it is guaranteed to last 50 years. No need to replace your steel doors except in the changing of design characteristics.

Sing Core uses very little energy and no toxic skilled-metal manufacturing methods with little or no waste in their patented manufacturing process of metal doors. Plus, due to their extreme light weight, these metal doors consume less energy in the delivery process, are much easier to manipulate and maneuver throughout the installation process, adding to the sustainability of Sing’s steel doors’ lifespan from creation throughout time.

That’s why you will find Sing Core used in very sensitive environments such as museums and archival installations which require very low volatile organic compounds (VOC) to protect their invaluable assets for centuries.

Guaranteed Steel Doors for 50 Years

Above all, your metal doors are backed in writing for remaining warp-free for 50 years, including the full structure over time. You can rest assured that you can have your steel doors guaranteed not to warp, bend, twist, or otherwise fail for fifty years.

Core Value of Steel Doors
It is how steel door shapes the future by invention of Sing Core.

See: Steel Door Gallery

Steel door technology has not made any major improvements since the development of EPS core which has higher insulation for replacing the paper core and wood based core used previously. Sing Core uses reinforced EPS or urethane foam to fill the voids of the structural torsion-box-like vertical veneer in those highly insulated Sing products, and… Viola! You have the strength which is approximately 30 times stronger than any other regular door made of foam. Steel doors made of patented Sing Core is the leading edge door technology that provides more insulation, strength and extremely lightweight. The end result is more Eco-friendly door; stronger and lighter weight without using heavy gauge steel but creating an even stronger steel door.
