Solution · Quality control
Quality control – inspected, traceable, documented
An inspection and test plan for every project, inspection at every stage from incoming steel to packing, full traceability from the mill heat to the piece on site, and a complete manufacturing data record (MDR) handed over with the structure – under certified fabrication and welding systems.
- ITP
- For every project hold and witness points agreed
- 100%
- Visual weld inspection NDT to the specified extent
- Heat → piece
- Full traceability mill certificate to piece mark
- MDR
- Quality dossier handed over with the steel
Quality you can inspect
Quality in steel fabrication is not a slogan – it is a plan, a set of inspections and a paper trail. Every World Steel project starts with an inspection and test plan (ITP) that lists each activity, the standard it is checked against, who checks it and where your inspector is invited to witness or must release the work.
Our fabrication and welding systems are certified – ISO 3834-2 for welding quality, EN 1090-2 EXC3 with CE marking, AS/NZS 5131 construction category CC3 and IAS AC472 for structural steel fabricators – and every inspection result is recorded in the manufacturing data record handed over with the structure.

Inspection & test plan
Hold points, witness points – agreed in advance
The ITP lists every inspection activity from design to packing, its acceptance criteria and its type: hold points, where work stops until released; witness points, where you or a third-party inspector are invited; and review and internal inspection points. Notifications are sent in advance so inspections never delay production.
Traceability
From the mill heat to the piece on site
Every plate and section is received against its mill certificate. When it is cut, the heat number is transferred to each part; when parts are assembled, the piece mark links them to the shop drawing, the welds, the inspection reports and finally the packing list. Ask for any piece on site, and we can show where its steel came from and how it was checked.
Welding & NDT
Qualified welds, independently tested
Welds are made to qualified procedures by qualified welders and visually inspected – every one. Non-destructive testing by MT, PT, UT or RT is carried out by qualified inspectors to the extent and acceptance criteria of the specified code, and every result is recorded against the weld and the piece.
Non-conformance
When something is wrong, it stops – and it is fixed
Any deviation is recorded in a non-conformance report, the piece is quarantined, and the repair or concession is approved before it moves on. Root causes are analysed and corrective actions tracked, and concessions are listed in the dossier – nothing is hidden.

Preguntas frecuentes
Can our inspector attend during fabrication?
Yes. Witness and hold points are agreed in the ITP and notified in advance; your inspector or a third-party agency is welcome at our factory.
Which certificates does the steel come with?
EN 10204 type 3.1 mill certificates for every heat; 3.2 certificates with independent validation can be arranged on request.
How much NDT do you perform?
Every weld is visually inspected; MT, PT, UT and RT are performed to the extent and acceptance criteria of the specified code or project specification.
What is in the MDR?
The quality plan and ITP, drawing register, material certificates with traceability, welding qualifications, inspection and NDT reports, dimensional and coating records, NCRs and release notes.
Can you trace a piece on site back to the mill?
Yes – the piece mark links to the heat number, the mill certificate and every inspection record of that piece.
