Description
20ft Dry box container for shipping/Container manufacturer
A dry box container is a steel box used to carry goods by sea, rail, and truck.
It keeps cargo dry, protected, and easy to move from one place to another.
At Container House Co., Ltd, a dry box container is built from steel, not from words.
How a Dry Box Container Is Manufactured
At Container House Co., Ltd, a container is made step by step on a real production line, starting from steel coils.
Steel Preparation
Steel coils are first unrolled and flattened.
Surface Cleaning and Protection
The steel sheets go through shot blasting to remove rust and dust.
After that, workshop primer is sprayed and dried to protect the steel surface.
Cold Forming and Shaping
Clean steel sheets are cold-processed and formed into container panels and parts.
Each part is shaped to fit the container structure.
Component Assembly and Welding
Side panels, roof panels, floor frames, and corner parts are assembled and welded.
This creates the basic container structure.
Full Container Welding and Sandblasting
The whole container body is welded together.
Then sandblasting is done again to prepare the surface for painting.
Primer Coating and Drying
Anti-rust primer is applied evenly and dried in the oven.
This helps the container resist corrosion during sea transport.
Middle and Finish Painting
Middle coating and interior paint are applied first.
Then exterior paint is sprayed, leveled, and dried.
This process is repeated to ensure paint thickness and durability.
Final Assembly Line
After painting, doors, seals, nameplates, and labels are installed.
Sealant is applied to joints and edges.
Bottom Coating and Water Tightness Test
Bitumen paint is applied to the container bottom.
Each dry box container goes through a water tightness test.
