Project Overview
The client is a local contractor in Jakarta specializing in steel structure engineering. They contacted us through our website to request quotes for galvanized square and rectangular tubes.
The client is currently working on several factory and warehouse projects simultaneously; this shipment of steel materials was intended for one of their medium-sized industrial park projects. The entire order was shipped in four high-cube containers, with a total weight of approximately 104 metric tons. The process from the initial inquiry to contract signing took nearly three weeks, with the main focus of communication being the galvanized coating standards and surface treatment requirements.

Specifications and Weight Distribution
This shipment consists of three specifications. The 50×50 size is used most frequently, primarily for purlins and wall beams; the 50×75 size is used moderately, for secondary beams and reinforcing door and window openings; and the 100×100 size is used least frequently, for main columns and load-bearing frames. The distribution is based on the customer’s material list and actual construction ratios.
| Specifications | Weight | Number of bundles | Number of pieces |
| 50×50×1.4mm | 48.0 tons | 48 bundles | 3,744 pieces |
| 50×75×1.4mm | 30.0 tons | 30 bundles | 1,860 pieces |
| 100×100×1.4mm | 26.4 tons | 26 bundles | 1,014 pieces |

Container Loading Plan
A total of four 40-foot high-cube containers will be used, with each container limited to approximately 26 metric tons. During loading, heavier sizes will be placed at the bottom and lighter ones on top. Wooden blocks will be used between each layer to prevent slippage, and steel straps will be crisscrossed and tightened at the container doors. The specific allocation per container is as follows:
| Container No. | 50×50 | 50×75 | 100×100 | Total number of bundles |
| Container 1 | 12 bundles | 8 bundles | 6 bundles | 26 |
| Container 2 | 12 bundles | 8 bundles | 6 bundles | 26 |
| Container 3 | 12 bundles | 7 bundles | 7 bundles | 26 |
| Container 4 | 12 bundles | 7 bundles | 7 bundles | 26 |
| Total | 48 bundles | 30 bundles | 26 bundles | 104 |
