Shipping containers have revolutionized the way cargo is transported on ships across oceans, it helped in ensuring the safety of the cargo but has also improved the overall cargo carrying capacity. As a result, shipping containers of different types are being built and used for transporting a variety of cargo around the world.

Almost all shipping containers are made from steel and have closed-top with hinged doors. They have corrugated walls on the top and bottom sides and are welded to the rails and end frames.

How are shipping containers made?

Shipping containers are made from materials such as steel, aluminum, fibre-reinforced polymer etc or a combination of all. You can watch the video below and understand better how shipping containers are made.

• 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.
• Surface preparation of these steel sheets is then carried out using sand blasting and priming to remove rust, dirt, contaminants etc.
• The sheets are then corrugated to improve the overall strength.
• Roof panels and floor braces are separately made and sheets for wall panels are then welded together.
• Square tubing is welded on the top of the walls.
• Once this is done, floor panels are assembled to form a floor frame.
• Door assembly and corner post assembly are also separately prepared.
• The door assembly is then installed on the floor frame followed by installation of wall panels.
• The corner posts, wall panels and door assembly are welded.
• The roof panel is then assembled and welded.
• Priming and painting is carried out.
• Wooden frames are varnished and prepared for flooring.
• Once they are installed in to the container floor, holes are drilled to attach flooring panels.
• The door hardware is finally installed along with rubber seals for watertight doors.
• The container bottom is then made waterproof followed by watertightness testing.
• The box is finally inspected to ensure watertightness or any other problem.
