Safety is the paramount concern. You must ensure the glass is Tempered Safety Glass (Toughened) complying with international standards such as EN 12150-1 (EU), ANSI Z97.1 (US), or AS/NZS 2208 (AU/NZ). For high-end B2B projects, recommend a thickness of 8mm to 10mm for frameless or semi-frameless designs to ensure structural rigidity, while 6mm is acceptable for fully framed economic models. Additionally, look for 'Easy-Clean' nano-coating options which reduce maintenance costs and enhance end-user satisfaction.
