Quality Control Documentation to Request at Metal Delivery

t497-44

When architectural metalwork arrives, request the approved drawings, material certificates for the steel or aluminum used, coating and finishing records, and a delivery checklist that matches the specification. Checking these papers before the crew unloads protects you from disputes about materials, dimensions and finish later on site.

Why documentation matters at delivery

Architectural metalwork such as railings, gates, stairs and glass partitions is made to measure, so the paperwork is the link between what was approved and what was built. A site engineer who accepts a delivery without the right documents has little ground to raise problems later. Clear records make it easier to confirm that the items match the drawings and the written specification agreed with the client or architect.

Treat the documentation as part of the delivery itself, not an extra. Ask for it before the goods come off the truck, while the supplier's team is still on site and able to answer questions.

Approved drawings and the specification

Start with the drawing set that was signed off after the on-site measurement. Each element should carry a reference that appears on the packing list and on the item itself. Compare the revision date on the drawing with the one your project team holds, because an old revision is a common source of mismatch.

Revision number and date on every drawing
Written specification listing profiles, finishes and fixings
Client approval reference

If the specification names a standard, such as the Israeli railing standard SI 1142, confirm with your engineer which requirements apply. Exact values should be checked against the engineer's calculations rather than assumed.

Material certificates and traceability

Material certificates confirm the grade and type of steel, stainless steel or aluminum delivered. Ask for certificates that identify the batch or heat number and link it to the profiles on site. Traceability matters most for structural members, load-bearing railings and any element where the material grade affects safety.

Check that the material named on the certificate matches the specification. A certificate for a different alloy or thickness is a reason to hold the delivery until it is resolved.

Coating and finishing records

Finishing is where many complaints start, so ask for records of the surface treatment. For galvanized steel, request the hot-dip galvanizing record. For powder-coated items, ask for the coating type, colour code and curing information. Stainless steel and aluminum should be documented with the finish type, such as brushed or polished.

Look at the colour and surface on arrival in good daylight and compare samples against the approved colour reference. Note any scratches, runs or uneven coverage on the delivery note before signing.

Dimensional and inspection checks

Ask for a dimensional inspection record or a checked packing list showing the measured sizes of key items. Dimensions taken from the on-site survey should match the drawing tolerances. For glass and aluminum frames, confirm opening sizes and fixing points before installation begins.

Where the supplier has an internal inspection sheet, request a copy. It shows which checks were performed in the factory before dispatch.

Delivery note, signatures and handover

The delivery note should list every item, quantity, reference number and any remarks. Check quantities against the packing list and mark anything missing or damaged immediately. Keep a signed copy, and file the documents with the project records so they can be found during handover.

Photograph the items and any damage at the time of delivery. Clear photos with dates make later claims far easier to settle.

Frequently asked questions

What is the most important document to request at delivery?

The approved drawing set with its revision date is usually the most important, because every other check depends on it. Without the correct revision, you cannot confirm that the items match what was agreed.

Do I need material certificates for every item?

Certificates matter most for structural and load-bearing elements, but it is reasonable to ask for them across the order. Your engineer can advise which items require full traceability.

What should I do if documents are missing at delivery?

Note the missing papers on the delivery note and do not sign for anything you cannot verify. Ask the supplier to provide them promptly and keep a record of the request.

Can I check finishes after installation?

It is better to check on arrival, because damage found after installation is harder to attribute and to fix. Inspect the surface and colour before the items leave the delivery area.

Common mistakes to avoid

Signing the delivery note without checking the drawing revision and quantities is the most common error. Accepting items with unrecorded surface damage also leaves the site team without a basis for a claim.

Our recommendation

Set up a one-page delivery checklist with the drawing revision, certificate references, coating records and quantities, and tick each line before signing. Keep the completed sheet with the photographs in the project file.

Summary

Request approved drawings, material certificates, coating records and a checked delivery note at every metalwork delivery. Verifying these at the gate protects the project from later disputes about material, size and finish.
