The roof panel is then assembled and welded.The corner posts, wall panels and door assembly are welded.The door assembly is then installed on the floor frame followed by installation of wall panels.Door assembly and corner post assembly are also separately prepared.Once this is done, floor panels are assembled to form a floor frame.Square tubing is welded on the top of the walls.Roof panels and floor braces are separately made and sheets for wall panels are then welded together.The sheets are then corrugated to improve the overall strength.Surface preparation of these steel sheets is then carried out using sand blasting and priming to remove rust, dirt, contaminants etc.Each shipping container starts with a big roll of steel, which is unrolled and cut into several sheets.This is done in dedicated factories with technically advanced machinery systems.Shipping containers are made from materials such as steel, aluminum, fibre-reinforced polymer etc or a combination of all. Construction of an ideal shipping container can be explained in an amazing video made by the Big Steel Box. The production of these steel boxes has thus increased around the world. Shipping containers are constructed and used in large number on container ships. There has been a sudden rise in the demand and usage of shipping containers in the past few years. They have corrugated walls on the top and bottom sides and are welded to the rails and end frames. Mostly, all shipping containers are made from steel and have closed-top with hinged doors. A list of different types of shipping containers used in the market can be found here. Some of the most commonly used types of shipping containers are 20ft, 30ft, 40ft, refrigerated etc. (Note: Directly Skip to the Amazing Video Below to Find Out How Shipping Containers are made!)
As a result, shipping containers of different types are being built and used for transporting a variety of cargo around the world.
Containerization has not only helped in ensuring the safety of the cargo but has also improved the overall cargo carrying capacity. Shipping containers have revolutionized the way cargo is transported on ships across oceans.
