A true testament to the durability and thus desirability of a material is the legacy of the structures and constructions that are left standing as time goes by. We know that the process of galvanization increases the ability of steel to withstand the nature forces of rust and corrosion bought on by water and the elements; let us take a look at the most notable of these structures;

As with all structures maintenance is required to ensure the safety and longevity of the structure; however few materials, at this cost can boast up to and above thirty years of maintenance free use as is seen with galvanized steel. Pictured above is the Boca Channel Bridge, located in the Florida Keys. It is consistently exposed to the corrosive elements of the sea water, however over its life of 42years it has not required any maintenance due to the galvanization of the steel whereas other, non galvanized bridges in the same area have had to be completely replaced.

This durability, despite the increased initial capital investment has been shown to save money over time as this maintenance or continual painting is not required, as would be the case with a non-galvanized steel construction. A prime example of this cost is the Goldengate Bridge in San Francisco, California (picture above), where 28 full time painters are required to constantly paint the bridge as its non-galvanized steel bears the brunt of nature and its original rivets are constantly being replaced with new galvanized ones.

Shanghai Metal Corporation offers galvanized steel in a multitude of forms that can be used to satisfy the applications mentioned above. These include piping, galvanized steel coils, strips, sheets, plates, wire, pre-painted steel, roofing material (in a number of profiles) as well as steel grating.

China has moved a step closer to creating a supersonic submarine that could travel from Shanghai to San Francisco in less than two hours. Not much is known about the team’s progress because it is a military project, but the SCMP reports that Germany, Iran and the US are working on similar projects.

The team from the Harbin Institute of Technology was inspired by a supersonic torpedo invented by the Soviet Union during the Cold War.

Water yields more friction on an object than air, which should mean that a submerged boat or weapon could never travel at the same speed as an airplane.

But the Soviet military figured out how to put a missile inside an air bubble to cheat this rule of science — a process known as ‘supercavitation’. They created the Shakval, a torpedo that could reach speeds of over 379 km/h, much faster than any other torpedo available.

The Chinese team, led by engineering professor Li Fengchen, sought to apply the same process to a submarine by overcoming two central problems. The submarine would need to be launched at speeds of up to 100 km/h in order to generate the air bubble. It would also require very advanced steering because the ship’s rudder would be inside the bubble, not touching the water. The answer was found in the form of a manmade liquid membrane that would cover the submarine’s surface. The result is a vessel that could reach the speed of sound, crossing the entire Pacific Ocean in approximately 100 minutes. Once supercavitation is harnessed, it could be incorporated into any underwater activity.

Shanghai Metal manufactures the stainless steel used in submarine hull manufacturing. To find out more, please visit our website, LinkedIn, Twitter, Facebook and Instagram. Or you could try our new mobile app by scanning our QR code.
