SecureSpanTm PULTRUDED GRATING
Pultruded grating and structural shapes are manufactured
through an automated process where continuous fiberglass
roving and mat are pulled through guides, a resin bath and
pre-formers. They are then wrapped with a synthetic veil
before being pulled through a heated die. The individual
components of pultruded grating (load bars and each piece
of tie bar) are pultruded separately. Load bars are then cut
to specified lengths as they exit the machine. They are drilled
at 6” or 12” centers for tie bar insertion. They are spaced
proportionately for the width of the panel at 3 ft., 4 ft., or
5 ft. Tie bar assemblies are then inserted into the load bar,
creating multiple bonded intersections of load bars and tie
bars. This provides the security of both a mechanically locked
and bonded connection. Finally, both load and tie bars are
sealed with corrosion resistant epoxy resin.
Pultruded grating is manufactured with a high percentage of glass within the resin matrix (65% glass
to 35% resin). The resulting product has high unidirectional strength, provides increased load capacity
over longer spans, and is corrosion resistant. SecureSpanTM Pultruded Grating Products are a lightweight, UV resistant, and durable making them a preferred alternative to steel or aluminum gratings.
