How to evaluate a perforated panel supplier

Three things separate a supplier who will deliver an installable facade from one who will not, and none of them appear on a price list: folding accuracy, dimensional tolerance across the panel, and deburring. A panel folded out of square will not sit in its opening whatever the price. Tolerances need to be stated as numbers rather than described as high quality, and perforated edges need deburring or the coating will fail at every hole.

Key points

• Ask for folding accuracy and dimensional tolerance as stated numbers, not adjectives
• Check how perforated edges are deburred, since coating fails first at a ragged hole edge
• Confirm whether stiffeners are welded or riveted and how the mark-through is controlled
• Request a production sample from the actual line rather than a showroom panel
