Aluminum bar, angle and tubing from standard mill stock. 6063 T5 and/or 6061 T6

B. Finishes

Clear etch anodizing to .0004 min. etch as per AA M32, C22, A31 unless otherwise specified.
Powder coat polyester or polyurethane painted finishes.

C. Glass

Solid clear tempered safety glass in thickness of 5mm to 6mm - AS-2 designation as per ANSI Z26.1
Solid clear tempered safety glass in thickness of 8mm through to 19mm - AS-2 designation with option to add ISO 3254 in accordance with ISO 614 test methods.
Solid tinted tempered safety glass in thickness from 5mm to 12mm - AS-3 designation.
Electrically heated glass consists of 2 or more layers of solid tempered safety glass combined with any of the above glass, sandwiching PVB and heating element. Heating element can be either resistive wire or oxide film. Options are available to add ISO 3434 for heated glass.

Note that all above solid tempered glass is considered under ASTM C1048 for heat-treated glass.

D. Fasteners

Retaining ring screws, hex bolts, washers, helicoils and any fastener required to secure 2 or more components together use either 18/8 or 410 stainless steel unless otherwise specified.

D. Rubber

Commonly used to retain and/or seal glass into aluminum profile is manufactured from a weather resistant synthetic rubber.

E. Sealant and Glazing Tape

Depending on the style and window application, sealing compounds may range from silicone to polyurethane. Butyl tapes are commonly used for most fixed glazing applications.
Synthetic rubber, flock coated rubber material and water repelling felt are also used in some sliding window applications. UV resistant sealant is also used where necessary.
