Product Sheet

5.4 Silca Grate panels must be directly
fastened to the supporting construction.
Where required, engineering calculations
and construction documents consistent with
this report must be submitted to the code
official for approval. The calculations must
verify that the supporting construction
complies with the applicable buildilng code
requirements and is adequate to resist the
loads imparted upon it from the products
and systems described in this report. The
documents must contain details of the
attachement of the panels to the supproting
structure consistent with the requirements of
this report. The documents must be
prepared by a registered design professional
where required by the statutes of the
jurisdiction in which the project is to be
constructed.
5.5 Anchoring of the flooring materials over
the Silca Grate is outside the scope of this
report. The determination of wind uplift and
other loads applicable in the flooring
materials must be determined by a design
professional.
5.6 A solid floor covering must be installed
over the Silca Grate.
6.0 EVIDENCE SUBMITTED
6.1 Testing in accordance with following ASTM D7032 provisions: Section
4.4 for flexure resistance, Section 4.5 for temperature effects, Section 4.7
for freeze thaw resistance, Section 5.4 for creep-recovery, and Section 5.5
for mechanical fastener resistance.
6.2 Testing in accordance with AC38 Section 4.1.2 for Ultraviolet light
weathering.
6.3 Testing in accordance with ASTM D7031 Section 5.10.2 for duration of
load (or creep-rupture resistance).
6.4 Testing in accordance with ASTM E84 for surface burning characteris-
tics (flame spread index).
7.0 IDENTIFICATION
The Silca Grate panels described in the report must be identified on each
panel with the name of the manufacturer (Silca System(, product name
Silca Grate, the allowable span and allowable load for the panel, the
allowable span for the stair tread, and the evaluation report number
(ESR-3748).
