We meet or exceed the ANSI 297.1-1984 and CPSC 16 CFR 1201, Category II requirements.


  • We offer the most up-to-date tempering/heat-strengthening process available. Tempered glass is great in homes, businesses, boats and automobiles.
  • We can either temper or heat-strengthen your glass from 3/16” – 3/4"
  • We can temper as big as 60” x 120” or as small as 4” x 8”
  • When tempering, we create an initial condition of surface and edge compression. This is achieved by heating the glass and then rapidly cooling the surfaces. This leaves the center hot and as it cools it forces the surfaces and edges into compression.
  • This glass will be four times stronger than annealed glass and will be able to withstand a wide range of temperature changes. When tempered glass breaks, it fractures into small, relatively harmless pieces. This is called “dicing” which reduces the dangers of injury.
  • Heat-strengthened glass has a surface compression between 3,500–10,000 psi or an edge compression between 5,500–9,700 psi. The fracture characteristics vary according to the psi surface and edge compression. The lower the psi, the more like annealed glass; the higher the psi, the more like tempered glass.


  • We use diamond grinding wheels to remove a portion of the glass edge. Then, we use felt wheels and a polishing compound to bring the edge to a shiny, clear finish.
  • We provide straight-line and pattern beveling on glass from 1/8” to ¾” thick.
  • Our standard bevel sizes for straight-line beveling are ¼” to 1½”.


  • Clean Cut - rough and sharp
  • Seamed - a rough grind is applied to the top and bottom to take off the sharpness
  • Ground - all edges are ground but not polished and have a satin-finished look
  • Flat Polish - the side edge is flat with a small seam or aris on the top and bottom edge of the glass
  • Pencil Polish - side edge is rounded which gives it a soft look
  • OGEE Edge - defined as an “S” profile
  • Mitered Edge - the edge of the glass is removed until it is only a fraction of its original thickness

Glass/Mirror Cutting

  • We have the most up-to-date glass-cutting machine to provide you with precision-cut glass pieces.
  • Hole-drilling
  • Notches and cut-outs for light switches
  • Finger pulls: handle grooves in sliding glass doors
  • Bonded boxes
  • Pattern cutting: diameters, ovals, race-track ovals, quarter rounds, various shapes


  • Sandblasting glass gives it a frosted appearance.
  • We can frost your glass to add some privacy to your bathroom shower or to improve the appearance of your home.
  • Our sandblasting process can be done to cover an entire side of glass or just to add some stripes to a piece of glass.
