APA STRUCTURAL I RATED SHEATHING^(c) Typical Trademark		Unsanded grade for use where shear and cross-panel strength properties are of maximum importance, such as panelized roofs and diaphragms. Can be manufactured as plywood, as a composite APA RATED STURD-I-FLOOR Typical Trademark, or as OSB. EXPOSURE DURABILITY CLASSIFICATIONS: Exterior, Exposure 1, Exposure 2. COMMON THICKNESS: 5/16, 3/8, 7/16, 15/32, 1/2, 19/32, 5/8, 23/32, 3/4.

APA RATED STURD-I-FLOOR Typical Trademark		Specially designed as combination subfloor-underlayments. Provides smooth surface for application of carpet and pad and possesses high concentrated and impact load resistance.Can be manufactured as plywood, as a composite APA RATED STURD-I-FLOOR Typical Trademark, or as OSB.

APA RATED SIDING Typical Trademark		For exterior siding, fencing, etc. Can be manufactured as plywood, as a composite panel or as an overlaid OSB. Both panel and lap siding available. special surface treatment such as V-groove, channel groove, deep groove (such as APA Texture 1-11), brushed, rough sawn and overlaid (MDO) with smooth -or texture-embossed face. Span Rating (stud spacing for siding qualified for APA Sturd-I-Wall applications and face grade classification (for veneer-faced siding) indicated in trademark. EXPOSURE DURABILITY CLASSIFICATIONS: Exterior, Exposure 1, Exposure 2. COMMON THICKNESS: 5/16, 3/8, 7/16, 15/32, 1/2, 19/32, 5/8, 23/32, 3/4.
(a) Specific grades, thicknesses and exposure durability classifications may be in limited supply in some areas. Check with your supplier before specifying. (b) Specify Performance Rated Panels by thickness and Span Rating. Span Ratings are based on panel strength and stiffness. Since these properties are a function of panel composition and configuration as well as thickness, the same Span Rating may appear on panels of different thickness. Conversely, panels of the same thickness may be marked with different Span Ranges. (c) All plies in Structural l plywood panels special improved grades and panels marked PS 1 are limited to Group 1 species. Other panels marked Structural 1 Rated qualify through special performance testing.
