The visual similarity of Junkers and Fokker aircraft during the next decade, especially after Reinhold Platz adapted some of the Junkers design concepts, but mostly crafted in wood for the Fokker designs ' wing structures instead of the all-metal Junkers construction techniques, is attributable to this early affiliation.

The 20th century saw an increasing use of technology in chair construction with such things as all-metal folding chairs, metal-legged chairs, the Slumber Chair, moulded plastic chairs and ergonomic chairs.

As it was becoming popular in other places in the automotive industry, all-metal body construction became featured by manufacturers as the decade progressed.

Only five were of all-metal construction, most were all-wooden.

By the late nineteen-thirties the widespread adoption of all-metal stressed skin construction of aircraft meant, at least in theory, that the aerodynamic penalties that had limited the performance of pushers ( and indeed any unconventional layout ), were largely negated ; however any improvement that boosts pusher performance also boosts the performance of conventional aircraft and they remained a rarity in operational service – so the gap was narrowed but not closed entirely.

By this time, Braun's film slide projectors were featuring high-quality optics and all-metal construction combined with sleek functionalist styling, and competed with higher-end Eastman Kodak and Leitz products in the global market.

Late-period battle axes tended to be of all-metal construction.

The basic form changed to all-metal construction by the 1880s.

The use of metal aircraft structures was pioneered before World War I by Breguet but would find its biggest proponent with Anthony Fokker who used chrome-molybdenum steel tubing for the fuselage structure of all his fighter designs, while the innovative German engineer Hugo Junkers developed two all-metal, single-seat fighter monoplane designs with cantilever wings: the strictly experimental Junkers J 2 private-venture aircraft, made with steel, and some forty examples of the Junkers D. I, made with corrugated duralumin, all based on his experience in creating the pioneering Junkers J 1 all-metal airframe technology demonstration aircraft of late 1915.

The pioneering Junkers J 1 all-metal monoplane of 1915, the first aircraft ever to fly with cantilever wings

This reduces maximum speed, and increases fuel consumption. A British Hawker Hurricane from World War II with cantilever wings Hugo Junkers endeavored to eliminate virtually all major external bracing members, only a dozen years after the Wright Brothers ' initial flights, to decrease airframe drag in flight, with the result being the Junkers J 1 pioneering all-metal monoplane of late 1915, designed from the start with all-metal cantilever wing panels.

It was the first aircraft to use an all-metal skin, had a single cantilever wing and had minimal external bracing.

However, in secret, the emerging technology of practical all-metal aircraft as pioneered by the work of Hugo Junkers, also incorporating cantilever structures within their metal envelopes had resulted in the first flight tests of the initial flight demonstrator of such technology, the Junkers J 1 monoplane at the end of 1915, heralding the wave of the future in aircraft structural technology for the postwar period and beyond.

It is an all-metal, low wing, tandem two-place, single engine aircraft with a conventional tail wheel landing gear and fabric-covered control surfaces.

* Hugo Junkers gets a patent for his thick wing / all-metal type aeroplane.

In 1929 he produced an all-metal monoplane with pilot and engine within the wing structure.

The Chipmunk was an all-metal, low wing, tandem two-place, single-engine airplane with a conventional tail wheel landing gear.

During the war, German engineer Hugo Junkers pioneered practical all-metal airframes as early as late 1915 with the Junkers J 1, whose techniques were adopted almost unchanged after the war by both American engineer William Bushnell Stout and Soviet aerospace engineer Andrei Tupolev.

Only the covered wings and tubular fuselage framework of the J 3 were ever completed, before the project was abandoned-the slightly later Junkers J. I armored sesquiplane had its all-metal wings and horizontal stabilizer made in the same manner as the J 3's wings had been, along with the experimental and airworthy all-duralumin Junkers J 7 single seat fighter design, which led to the Junkers D. I low-wing monoplane fighter introducing all-duralumin aircraft structural technology to German military aviation in 1918.

The all-metal " Tonka Trucks " were sold throughout the world and earned a reputation as being indestructible, although the steel has been increasingly replaced by plastic from the late 1980s onwards.

The hood and front grill have been redesigned, the front fenders are now all-metal rather than painted composite material, and the wheel arches were squared off.

By then, the initial field of over 60 had been whittled down to 20, including the three purpose-built de Havilland DH. 88 Comet racers, two of the new generation of American all-metal passenger transports, and a mixture of earlier racers, light transports and old bombers.

The Central Design Office or TsKB () based there produced bombers and some airliners, which in the years before World War II were based partially, especially in his 1930s-era designs, and on the all-metal aircraft design concepts pioneered by Hugo Junkers.

Designed by Ken and Lew Norris, the Bluebird K7 was an all-metal jet-propelled 3-point hydroplane with a Metropolitan-Vickers Beryl jet engine producing of thrust.

While the 224 was being built, Mitchell was authorised by Supermarine in 1933 to proceed with a new design, the Type 300, an all-metal monoplane that would become the Supermarine Spitfire.

Such wings were already being developed by several designers, including Hugo Junkers, whose work during 1915 resulted in the pioneering Junkers J 1, the world's first practical all-metal aircraft of any type.

Special tracks that incorporate rubber pads can be installed for use on paved surfaces to prevent the damage that can be caused by all-metal tracks.

Since it was the first design from Junkers to serve in the Luftstreitkräfte's " J-class " of armored, infantry co-operation aircraft, which also had aircraft designed by Albatros and AEG serving with it in the same capacity, the curious and confusing instance of the Junkers J 4 armored all-metal sesquiplane getting the German military designation " J. I " was one caused solely by the Luftstreitkräfte's choice of letter for all of their armored, ground forces co-operation aircraft class in World War I, with other J-class aircraqft coming from Albatros Flugzeugwerke and the aviation division of AEG.

He later moved to Lockport, New York, where he continued inventing, but his work with pumps was continued by Seabury S. Gould Sr. who cast the first all-metal ( cast iron ) pump and founded Goulds Pumps, a worldwide pump manufacturer, which was the world's largest company dedicated to producing only pumps when it was taken over by ITT Technology in 1997.

* First successful all-metal aircraft flies, the Tubavion monoplane built by Ponche and Maurice Primard in France.

These sometimes cause confusion-for instance the military " J " series is quite distinct from the " J " designations ( as in the pioneering, all-metal Junkers J 1 demonstrator monoplane of 1915-16 ) for the designs of Hugo Junkers-the factory designation of the ( military ) Junkers J. I armored, all-metal sesquiplane was the Junkers J. 4.
