Scroll down to the Tube Laser Flyer
Parts produced with
Alro’s one step laser
technology.
Laser cutting slots and
tabs eliminate the need
for clumsy clamping.
Your parts can be produced from
any structural shape including
angle iron and beams.
After laser cutting, most parts
are ready for assembly.
Notches can be cut to the desired angle for precision
forming. Laser cuts are smooth, practically eliminating
the need for grinding and deburring.
Holes are cut to the desired diameter eliminating the
need for drilling or punching. Tapping also available.

FIBERGLASS STANDARD STRUCTURAL SHAPES
A wide variety of standard shapes and custom composite shapes can be produced
in a choice of standard resin systems. These generally cover most applications
and outperform steel, aluminum, and wood. Fiberglass grating products are impervious to most industrial and environmental corrosives. They are non-conductive,
electromagnetically transparent, provide thermal insulation, and are less costly
to maintain over the life of the product. Manufactured via the pultrusion process,
these structural shapes are strong, flexible, dimensionally stable, and inexpensive
to install and remove with simple hand tools.
• IFR: Isophthalic polyester flame-retardant, light gray.
• VFR: Vinylester flame-retardant, beige.
Standard lengths are 20 ft. (Custom lengths available upon request.)

Applies when flanges of channels are toed in or out. For channels 5/8" and under in depth, the permissible out-of-square is 3/64 in./in. of depth.
Tolerance is per inch of flange width for S, M, C, and MC shapes.
