This specialized P-shape pipe, measuring 4175mm in length with an 18mm diameter, is the beginning of engineering to ensure the IBC steel frame can withstand the the rigorous mandatory UN drop test. The "P" shape is ingeniously crafted to provide a broad, horizontal flat area. This surface isn't just flat-it is reinforced with precisely raised ribs. These ribs create the optimal, stable platform for the secure welding of all twenty vertical support tubes that will form the sidewalls of the cage.
The manufacturing process of this critical component begins with a coil of galvanized steel at a durable 80g/㎡ layer of zinc. From this raw material, the pipe is born through a multi-stage, automated process. It starts with die-cutting to create the initial metal blank, followed by precise tube shaping to form the iconic P-profile. Advanced top horizontal tube welding techniques seal the longitudinal seam, after which stamping and punching operations add the crucial ribs and any necessary interface features.
One such vital feature is a small, round auxiliary tube inserted along one side of the main horizontal body. This element is a key facilitator in the final assembly magic. Once the vertical tubes are welded on, the entire welded steel grid is a flat plane. To transform this plane into a three-dimensional square cage, the grid is bent at its corners. This small inserted tube acts as the precise interface and pivot point during this bending and clinching process, ensuring the framework locks into a perfect, rigid, and square geometry.
Constructed from 1.0mm thick galvanized steel sheet, the top horizontal tube offers an ideal balance of formidable strength and manageable weight. It arrives at the assembly line perfectly formed, prepared to be swiftly and accurately married to the frame welding equipment, where it begins its life as the defining backbone of a container built to withstand the world's demands.

FAQ
Q:There is a small insert tube that is commonly shipped separately. Can you insert this small tube into this top tube?
A:Yes. We manufacture the top tube with a small tube inserted and prepared for the welding bed. Please let us know which side you prefer the welding on the p-shape, so we know on which side to insert the small tube.
