What we handle here

Tempering under the same roof Cut, printed and tempered in one building, so a print revision doesn't ripple through three subcontractors.
Quotes in a day, parts in a week Most quotes go out within one business day; production typically ships in 5–10.
Scheduled releases Blanket POs with weekly pulls. We hold the released glass so your line can take it on schedule.

SEND IT OVER

A drawing beats a phone call

DXF, DWG, PDF, a dimensioned sketch, or a photo of the part. We check holes and edge distances against the tempering limits before we price it, so the number is for a part we can actually make.
