Glass Vitrine Quality Control: Checks During Production

Why Quality Control Starts Before Production

Most problems with glass vitrines begin long before the first cut. A wrong measurement, an unclear drawing or a missing detail on the specification will show up later as a gap, a misaligned frame or a door that does not close properly. For this reason, the quality process starts with the on-site visit.

Our team measures the opening on site, checks the floor and wall levels, and notes the surrounding conditions. These notes are compared with the written specification and the drawing before anything goes into production.

Measurement and Drawing Review

A second measurement is taken from the drawing once it is prepared, and the two are compared. Any difference is resolved with the client, architect or interior designer before the order moves forward.

• Opening width and height at top, middle and bottom
• Floor level and any slope in the surface
• Glass thickness, type and edge finish
• Frame profile, door direction and handle position

Checks During Factory Production

During fabrication, the frame profiles are cut, joined and checked for square and straightness. Each corner is measured against the drawing, and the frame is tested dry before any glass is set in place. This makes errors visible while they are still easy to correct.

Glass pieces are checked for dimension, edge quality and any surface marks before they are fitted. Hardware is tested for smooth movement, stable hinges and correct locking.

Finishing Inspection

After fabrication, the metal parts go through the agreed finishing process, such as hot-dip galvanizing or powder coating, depending on the project. Finished surfaces are inspected for even coverage, colour consistency and the absence of runs, bubbles or damage from handling.

Parts are protected during transport so that the finish arrives in the same condition in which it left the factory.

Installation Checks On Site

Installation is where the planning pays off. The installer checks the level and plumb of the vitrine, secures the fixings to the structure, and confirms that doors and panels operate freely. Sealing and gaps are checked against the specification.

Before handover, the completed unit is walked through with the client so that any remaining point can be recorded and addressed.

Handover and Documentation

At handover, the drawing, the approved specification and the checklist used during production are available to the procurement team. This gives a clear record of what was agreed and what was delivered, which simplifies later verification and any future changes.

If any difference from the approved drawing was agreed during the project, it is noted in writing so that the final record matches the installed work.

Frequently asked questions

What is checked first in glass vitrine quality control?

The opening is measured on site and compared with the drawing and specification. Catching differences at this stage is the most effective way to avoid problems later.

Are glass parts inspected before installation?

Yes. Each glass piece is checked for dimensions, edge quality and surface marks before it is fitted into the frame.

Who approves the drawing before production starts?

The client approves the drawing and written specification before production begins. Architects and interior designers are included when they are involved in the project.

What happens if a difference is found during installation?

The installer records the difference, and the team agrees on the correction with the client. Any agreed change is documented so the final record reflects the installed work.

Common mistakes to avoid

Relying only on the final inspection at delivery, instead of checking measurements and drawings early, is the most common cause of avoidable problems. Skipping the written specification also leads to disagreements about what was agreed.

Our recommendation

Ask for the measurement notes and the approved drawing before production begins, and keep them with the project file. Comparing these documents with the delivered unit makes verification quick and clear.

Summary

Quality control for glass vitrines runs through measurement, drawing, production, finishing and installation. Checking each stage against the approved specification protects the result for everyone involved.
