1 DUR-O-WAL TrussProduct Information/Submittal SheetDUR-O-WAL TRUSSP roduct Description DUR-O-WAL TRUSS is a prefabricated reinforcement especiallydesigned for embedment in the horizontal mortar joints ofmasonry. It is manufactured in 10 ft. lengths. DUR-O-WALtruss consists of two or more parallel longitudinal deformedrods weld-connected to a continuous diagonally orientedcross rod which forms a TRUSS at least one longi-tudinal side rod for each bed spacing ofthe side rods is approximately 2 inches less than the nominalthickness of the wall or wythe in which the reinforcement isplaced. DUR-O-WAL TRUSS is manufactured in accordance withUniform Building Code Standard UBC 21-10 andACI530/ASCE6/TMS402 Building Code Requirements forMasonry Uses DUR-O-WAL TRUSS reinforcment is used in a number of applica-tions to improve the performance of masonry walls.

2 Some are: To control shrinkage cracking To provide principal horizontal reinforcement in engineered masonry walls To bond masonry wythes together in composite and cavity walls.* To reinforce stack bond masonry. To bond intersecting walls.* Tri-Rod or Double Side Rod TRUSS should not be used with insulated cavity DUR-O-WAL recommends mill galvanized (.10 oz. psf) for interior applications. DUR-O-WAL recommends hot dipped galvanized ( ) for exterior applications. Also available in Class 1, Class 3 or stainless steel. Check local building code for specification.* Interior application where high moisture content is involved (locker rooms, food centers), hot dip galvanized Tests show that continuous reinforcement improves the perfor-mance of walls by providing: Crack Control Greater elasticity Butt welded single plane Construction Higher ductility High bond with deformed side wires Better resistance to rain penetrationSpecifications All DUR-O-WAL wire products are made with wire conform-ing to the ASTM STANDARD SPECIFICATION for COLDDRAWN STEEL for CONCRETE REINFORCEMENT,ASTM A82 and ASTM STAINLESS STEEL material conforms toASTM STANDARD SPECIFICATIONS A580, TYPE and Placement Place joint reinforcement directly on masonry and placemortar over wire to form bed joint.

3 * Minimum ounces of zinc coating per square foot of uncoated wire surface1 BOCA and SBCC Codes allow this finish for interior Basic wire acquires rust in warehousing, transit, and job site storage. Therefore, DUR-O-WAL does not assume any responsibility for rusted material.** Specify and insist on DUR-O-WAL ! DUR-O-WAL will certify on request that its hot dip galvanized (ASTM A153) product will have a minimum of oz. of zinc per square foot-33% more corrosion protection than minimum standard does not recommend using epoxy coating forjoint reinforcement, anchors or TRUSS Increased horizontal flexual strength More Construction economy Lower life cycle costsReference SpecificationsFinishCoating*ASTM A82 (for cold drawn steel wire)Brite Basic2uncoatedRegular Mill Galvanized ASTM A 641 1 Mill Galvanized ounce zinc coatingASTM A641-Class 1 Mill Galvanized ounce zinc coatingASTM A641-Class 3 Mill Galvanized ounce zinc coatingASTM A153-Class B-2**Hot ounce zinc coatingCustomer Service Aurora, IL (800) 323-0090 Folcroft, PA (800) 368-2035 Birmingham, AL (800) 821-9296 Phoenix, AZ (800)
