RE: Review ATI test report on fiberglass coated plywood steps for
compliance with the most recent code versions
Dear Mr. Johnson:
W e have received the test report you submitted from Architectural Testing (ATI), York, PA. The details
are as follows:
Report number: 01-37911.04, dated 11/7/03
Title: Step Performance Test Report
Products covered:4-Tread, Dura-Grip II, Step Unit [A five riser, four tread step fabricated with
pressure treated lumber and fiberglass].
At your request, we have evaluated the test report against the building codes outlined below.
CODE 2015 International Building Code (IBC)
Stairway Dimension Requirem ent Tested Value (2)Compliance
W idth (1)36" minim um 38"Pass (1)
Riser H eight 7" maxim um, 4" m inim um 7"Pass
Tread Depth 11" minim um 11-1/2"Pass
Tread Leading Edge Radius 9/16" maxim um Less than 1/2"Pass
CODE 2015 International Residential Code (IRC)
Stairway Dimension Requirem ent Tested Value (2)Compliance
W idth 36" minim um 38"Pass
Riser H eight 7-3/4" maxim um 7"Pass
Tread Depth 10" minim um 11-1/2"Pass
Tread Leading Edge Radius 9/16" maxim um Less than 1/2"Pass

CODE 2017 Florida Building Code (FBC)
Stairway Dimension Requirement Tested Value (2)Compliance
W idth 36" minim um 38"Pass (1)
Riser Height 7" maxim um, 4" m inim um 7"Pass
Tread Depth 11" minim um 11-1/2"Pass
Tread Leading Edge Radius 9/16" maxim um Less than 1/2"Pass
Notes: (1) 44" minimum or 36" if serving an occupant load less than 50.
(2) The tested values have been taken from the referenced ATI test report, RADCO
has not independently verified any of the actual dimensions, and is not responsible for
the accuracy of these dimensions.
CONCLUSION:
There have either been no changes in the dimensional requirements in the IBC, IRC and the FBC or,
as in the case of the Tread Leading Edge Radius, the requirements have been altered minimally, when
compared to the requirements listed in the referenced ATI test report number 01-37911.04, dated
11/7/03. The product is therefore in compliance with the dimensional requirements of the editions of
the IBC, IRC and the FBC referenced above for the four (4) dimensions shown in the tables.
st that this proposal has been responsive to your objectives. Please do not hesitate to call if you have
any questions. As always, we look forward to working with Style Crest and to starting this program in
the near future. This proposal is valid for 90 days.
Sincerely,
R A D C O
