ONE WORLD is so happy to share with you that we delivered 1*20GP 28 tons of Q235 square tube to our South Africa client in 30th April. Those square tube will be used to produce the metal bobbin for cable.
At the beginning, our client would like to get a price for steel square tubing one container 20 FCL full 25mm*25mm*1.6mm and single tube length is 6m.
Considering the tube material is Q235 and the length of 20GP container is 5.89m, 6m tube is too long to put in. So we suggest our client the single tube length could be 5.8m. After confirming the length and other details, our client place the order in the last month and we finished the production this month quickly.

Introduction
Q235 is also called A3 plate.
Common carbon structural steel-plain plate is a kind of steel material.
Q represents the yield limit of this kind of material, and 235 in the back refers to the yield value of this kind of material, which is about 235MPa.
It is widely used because of the low carbon content, better comprehensive performance in strength, plasticity and welding properties.
