How do you inspect second-grade 100 mm wall panels at delivery?

Identify the product and check that the available documents cover the pieces on offer. A wall panel of the same thickness may have a different core or facings from those specified. Without those details it is difficult to judge suitability, even where no surface damage is visible.

View the facing from several directions, including in oblique light. This reveals dents and variations in flatness. Protective film can give misleading reflections. Agree how to inspect representative areas while protecting the rest of the batch.

Distinguish dirt, superficial scratches and damage through the coating. Record depth and position. Agree the method and extent of any repair. An unsuitable touch-up paint may give poor appearance or inadequate long-term protection.

At the ends, inspect the facings, core and their bond. Look for crushing during handling. Check joint edges and profile geometry where adjacent panels will engage. Damage there can prevent assembly even if the centre of the panel looks good.

Avoid forcing deformed edges into position. Investigate suspected delamination or substantial damage and set a doubtful piece aside for assessment. A trial fit can reveal a joint problem but cannot confirm performance or suitability for the intended application.

Mark each panel on a simple elevation drawing. An accepted cosmetic defect can then be placed in a less prominent position, provided laying direction and joint compatibility are maintained. Check before reversing or turning a panel.

Account for cuts at openings and wall ends. If the damaged zone can be cut away, show it on the cutting schedule and measure the usable remainder. This gives a realistic usable quantity before accepting the batch price.

Record quantities, dimensions, batch identification and deviations. Photograph the whole panel and the defect close up, linking both to its schedule number. Identify pieces accepted, held for clarification and outside the order. A single photograph of a stack cannot do this.

Distinguish previously accepted deviations from transport damage. Check the agreed procedure for nonconforming goods and the scope of the warranty. Outlet terms vary. A clear record shows whether the delivery matches what was agreed.

Keep the pack reference for every piece. If the same flaw appears further down the pack, this lets you identify the remaining panels that need checking.

Add sorting, necessary repairs and unusable material to the purchase price. If the batch is short of suitable pieces, check replacement availability before buying. Another batch may differ visibly in colour, and incompatible joints may prevent installation.

Decide on a particular set of panels for a particular wall. A saving is meaningful once suitability and preparation costs are known. If the core, facings or joints are in doubt, obtain an assessment before accepting the defect.
