Erie Electroverre Glass

Applications: Solar, Laboratory, Industrial

Standard Dimensional Tolerances

Width: we can cut to your particular size needs, be it large or small. Our normal dimensional tolerances for sizes larger than l0cm are + 0.5mm. For parts smaller than I0cm by I0cm, the tolerances are +/- 0.Imm. Upon request we can offer tighter tolerance controls.

Should your products require ground or polished edges, beveled or clipped corners, you will find our products surpass all other products on the market today.
