Steel & Construction

Traceability means the ability to identify a specific piece of steel in a structure, throughout the life of the structure, and its specific mill test report (MTR). Each batch of steel produced by the mill is tested for chemical content and mechanical properties, and the results are recorded on a MTR, which is provided to and maintained in the records of the fabricator.

Each piece that delivered in roll form labelled with an identification mark that relates to the corresponding MTR. The fabricator applies an identification mark to each piece they produce. Because this piece mark remains with the piece throughout the fabrication and erection process, the material is traceable back to the MTR for that individual piece. Saito have observed an industry practice where a tag is inserted into a small steel tube prior to blasting and / or painting stations.


Saito can help with Traceability:


Lot traceability vs. piece-mark traceability vs. piece traceability: Lot traceability means that the materials used in a given project can be traced to the set of MTRs for that project. Piece-mark traceability means that the heat number can be correlated for each piece mark, of which there can be many individual pieces. Piece traceability means that the heat number can be correlated for each piece, which effectively demands separate piece marks for each piece.

Each of these three successive levels of traceability adds significant costs. Piece traceability, the most expensive option, is necessary only in critical applications, such as the construction of a nuclear power facility. Piece-mark traceability is often specified for main members in bridges. Lot identification is most common in other applications where traceability is required.


To pick an order and issue it to the production line can be done via a pick slip and a pen to check off what is required. But most warehouse operations are seeking greater accuracy through scanning of the goods issued. Some sophisticated systems also require the team member to scan the location to ensure they are picking the right product batch. Increasing both productivity and pick accuracy!

Most steel fabrication warehouses operate on a First In First Out (FIFO) basis rotating stock.  If a steel fabrication company relies on their staff to know where everything is or organise SKUs in alphabetical or numerical order to find them, with fluctuating volumes, grades and human error could mean stock may be lost or hard to locate. Whereas if you give SKUs a dedicated “home” location in the warehouse


Whether a finished fabricated beam or concrete reinforced steel bar or mesh the next stage is to tag it for delivery. Industry standard within New Zealand for concrete reinforcing bars or mesh is to colour code the project so that load out is easily achieved via common colour tags.

Tags are also used for steel beams in major building projects to identify to the construction crew where they fit in the build. These do not have to be colour coded to the project.


There is always a variance between what production say that they produced and what the warehouse said it issued or received in finished goods. Therefore, there will be stock discrepancies.

Whether an annual, twice per year or rolling stocktake warehouses are required to take stock of their goods on hand and to match them with stock recorded on their system. Most stocktakes are performed “blind” where a team member scans in the product and creates a file to upload and compare with the stock in the system. A stocktake can be done via a printout and a pen to record what is counted. Most warehouses seek to scan goods for speed and accuracy purposes.
