Description
DIN8902 soda-lime tempered glass provides an economical, safety-tempered viewing window for general industrial equipment, lighting front panels and instrument displays. Available in standard stocked sizes or CNC cut to custom diameters and thicknesses.
Key features
- Manufactured to DIN8902 requirements for soda-lime tempered glass discs.
- Safety tempered — fragments into small granular pieces on breakage.
- Cost-effective alternative to borosilicate for non-high-temperature applications.
- Standard stocked diameters for fast delivery; custom cut & edge finishing (polish, bevel) available.
- Optional drilling, countersinking and hole patterns for flange mounting.
- Clear optics with high visible transmission; suitable for instrument windows and protective front panels.
Why choose DIN8902 soda-lime tempered glass?
If your application does not require high temperature or aggressive chemical resistance, soda-lime tempered glass per DIN8902 offers excellent optical clarity and mechanical safety at a lower cost than borosilicate. It’s ideal for sight windows, lamp covers (spotlights), control panels, and general protective glazing.
