FIBERGLASS STRUCTURAL SHAPES AND PLATE

1 FIBERGLASS STRUCTURAL SHAPES AND PLATE2 IntroductionWhat you see below is not the erection of a steelstructure. Rather, it is a structure beingassembled using EXTREN FIBERGLASS structuralmembers. Today, EXTREN is replacing steel,aluminum, and wood in a wide variety ofstructural applications. Why? Because EXTREN is a problem solving material. This brochureprovides basic information about the EXTREN product line and shows many examples of howEXTREN provides long-term, cost effectivestructural solutions for end users in variety ofmarkets and features of EXTREN FIBERGLASS STRUCTURAL shapesare readily translated into user benefits: Corrosion Resistant Low in Conductivity Thermally and Electrically Nonmagnetic Electromagnetic Transparency Lightweight Weighs 80% less than Steel High Strength Dimensional Stability Low Maintenance Custom ColorsStrongwell's 350,000 sq.

It isproduced in more than 100 standard SHAPES . All EXTREN shapeshave a surface veil to protect against glass fibers penetrating theresin surface in service and to increase corrosion and UV is offered in three series designed for differentenvironments and applications:EXTREN 500An all-purpose series utilizing an isophthalic polyester resinsystem with a UV ::::: olive greenEXTREN 525An all-purpose series utilizing a fire retardant isophthalicpolyester resin system with a UV : slate gray (plus certain handrail and fixed-laddercomponents in yellow)EXTREN 625A premium series both fire retardant and highly corrosionresistant utilizing a vinyl ester resin system with a :Color:Color:Color:Color: beigeThe three EXTREN series.

5 strongwell 's extensive experience infabrication procedures, joint design and stress analysis ofcomposite assemblies, when combined with the use of Strongwellfiberglass products, results in structures of superior, cost-effectivedesign and STRUCTURAL integrity. Clear, straightforward drawings ofstructures are provided to the customer for approval beforefabrication begins unless customer drawings are It YourselfThe strongwell Design Manual on CD-ROM, developed by strongwell ,is the most complete reference guide in the industry for designingFRP structures and is used by more engineers and architects than anyother FRP engineering guide. With more than 400 pages ofengineering data, the Design Manual includes properties of materials,beam and column load tables, empirical design equations and samplecalculations, connection details, and FRP product and fabricationspecifications.

6 strongwell 's Design Manual is based upon years ofextensive product testing and experience in monitoringapplications of EXTREN FIBERGLASS STRUCTURAL SHAPES , fiberglassgrating, handrail and other proprietary pultruded ! FIBERGLASS reinforced thermoset plastic composites are non-homogenousmaterials ( , their strengths and behavior are dependent upon the designof the composite and reinforcement). Other FIBERGLASS STRUCTURAL shapeswith a similar exterior appearance to EXTREN SHAPES are likely not equalin any other way to EXTREN , including glass content, glass placement,glass type, wet out, resin mixture or pull speed. Do not use the StrongwellDesign Manual to design a structure unless you assure that only EXTREN structurals are Product LogoA product logo identification program has been implemented byStrongwell after designers and specifiers of EXTREN learned thatproblems were occurring because sellers or contractors weresubstituting look-alike July 1, 1993, all EXTREN FIBERGLASS STRUCTURAL SHAPES andplate have been imprinted with the EXTREN logo every three feetdown the length of the part.

7 Square and round tubes have the logoimprinted inside the shape. Small and unobtrusive, the logoassures customers that they are getting EXTREN propertiesbacked by corrosion, mechanical and STRUCTURAL testing asconducted by with EXTREN EXTREN can be joined by adhesives aswell. The strongest connections can bemade by using a combination ofmechanical fasteners with fabrication techniques forEXTREN are covered in strongwell 'sEXTREN Fabrication and PreparationEXTREN SHAPES and PLATE can besawed, drilled, routed and turned on alathe or other machine tool. Punchingshould be limited to thicknesses of 3/16"and under. Carbide or diamond-tippedsaw blades and tool bits arerecommended for faster speeds andlonger-tool life. Cut edges should alwaysbe sealed. EXTREN cannot be bent,rolled or pressed as can addition to being the world's largestproducer of pultruded parts, strongwell isalso the largest fabricator of structuresutilizing pultruded fabrications include beam, columnand PLATE structures, all-fiberglassbuildings using foam core panels,platforms and other custom fabricationsinvolving grating and handrail.

9 In itssimplest terms, pultrusion is the process ofpulling FIBERGLASS (or other) reinforcements through a bath of thermosetting resin and into a heated forming-and-curing die to produce composite STRUCTURAL SHAPES . Reinforcementplacement, resin formulation, catalyst levels, die temperature and pull speedare critical process parameters. strongwell is one of the pioneers of thepultrusion process with more than 60 pultrusion machines in three plantlocations across the United addition to EXTREN , strongwell uses the pultrusion process to produce many otherproducts. For example, the EXTREN DWB is a combination of carbon and glass 36" x 18" double web beams weigh 70 lbs. per linear foot. The process is used toproduce complex profiles and pultrude over cores. Pultrusion is also utilized for partsintegration and to produce easy toassemble and AvailabilityStrongwell manufacturing facilities are ISO-9001:2000 ensures the utmost quality standards for producingEXTREN STRUCTURAL SHAPES in a world class facility.
