S355JR Steel Pipes, Hollow Sections and Universal Beams for a Singapore Wastewater Project
S355JR steel pipes, hollow sections, and universal beams were supplied in two batches for a wastewater treatment project in Singapore.

Project Background
We joined the tender for this Singapore wastewater treatment project in early 2023.
At first, the product list looked manageable. That changed as the tender moved forward. The buyer revised the design drawings several times, and each revision brought a different combination of pipes, hollow sections, and beams.
Some sizes disappeared from the list. New ones were added. A few of the requested sections were rarely produced, so availability and lead time became part of every discussion.
Our team worked from the latest drawing set each time. We checked the changed sections with the factory, then replied with the options that could actually be produced or sourced.
Where the exact section was difficult to arrange, we sent the buyer an alternative for review. The comparison covered the main dimensions, technical parameters, expected cost difference, and production time. The buyer could then decide whether to keep the original requirement or approve the replacement.
The tender went through several rounds. In September 2023, the buyer awarded us the order. Both sides finalized the contract in mid-October.
That left a short production window.

Confirming the Final Steel List
The final supply scope included round steel pipes, square and rectangular hollow sections, and universal beams in S355JR steel.
The drawings changed several times during the tender. Before the factory started production, we checked the final order against the latest drawing set and took out any sizes from the earlier versions.
We checked the product type, section shape, size description, and quantity line by line. The factory also reviewed which items needed additional processing and how much time had to be left for that work.
The photos supplied for this case show several of the confirmed product forms.
One image shows large universal beams stacked at the factory. Their open sections face the camera, and identification papers can be seen inside some of the beams.
The loading photos show square and rectangular hollow sections, round pipes in several diameters, angle sections, and beams. The products were not all packed in the same way because their shapes and sizes were different.
The complete dimension schedule was not included in the material supplied for this article. For that reason, no pipe diameters, beam sizes, wall thicknesses, lengths, or order quantities have been added.
Working Around a Tight Production Window
The contract was confirmed in mid-October, but the first shipment was required before the end of the month.
Waiting until every item was ready would have delayed the material that had already been completed. At the same time, the factory still needed enough time for the remaining production and processing work.
By late October, some items were ready while others still needed more production time. We agreed not to hold back the finished material. The ready pipes, hollow sections, and beams went in the first shipment, and the factory completed the balance for the second. We prepared a separate product list for each batch so the buyer knew what was leaving in October and what would follow in November.
Third-Party Inspection of the First Batch
The first batch required an SGS inspection before shipment.
SGS checked the first batch before shipment. Once it passed the inspection, we arranged the loading.
The detailed inspection report was not included in the material available for this case. No unconfirmed test items, measured values, sampling quantities, or report numbers have been added.
Packing and Container Loading
The first loading image shows several types of long steel products inside a container.
Rectangular hollow sections are stacked along the lower left and centre. Angle sections and other profiles are grouped beside them. Universal beams are positioned along the right-hand side. Bundles of round pipes can be seen farther inside.
A second photo shows large universal beams before loading. The sections are stacked in rows, with their ends facing outward. Some surface rust is visible on the untreated steel.
Another container photo shows rectangular hollow sections arranged in blocks. Round pipes are bundled above and between the hollow sections. The open ends make the different product shapes easy to identify.
The two remaining loading photos focus on the round pipes. Larger pipes are grouped together, while bundles of smaller pipes are stacked separately. Metal bands are visible around several bundles.
The loading photos show the goods inside the containers. We do not have the full packing list or the container details, so neither has been added here.
Two Shipments to Singapore
The first batch left for Singapore on October 31, 2023.
After that shipment, the factory finished the remaining products and processing work. The second batch was completed and shipped in mid-November.
The buyer received the first group of completed products without waiting for the balance of the order.
Notes for Similar Wastewater Project Buyers
When drawings are still changing during a tender, every revision should have a clear date or number. The quotation, final contract, production list, and inspection documents should all refer to the same version.
For uncommon pipes or structural sections, it also helps to confirm whether alternatives are allowed. A useful comparison should include the section dimensions, steel grade, unit weight, processing requirements, price difference, and expected lead time.
Because the order went out in two lots, we made a separate packing list for the October and November shipments. The buyer could then check which pipes, hollow sections, and beams were included in each load.
