By describing the extensive line of bar gratings offered by Grating Paci c, this catalog serves as a useful tool for de- ning materials, methods of assembly, fabrication, and n-ish alternatives. Whether your needs include only a simple stair and platform or an entire industrial processing facility, the products described in this catalog offer a comprehen-sive menu of open metal ooring features from which the most appropriate may be Bar Grating AdvantageFor nearly a century, metal bar Grating has been the predom-inant choice for open metal ooring.

2 Features that make bar Grating the preferred product include: Appropriate Materials Carbon steel, aluminum , stain-less steel, and specialty alloys provide safe, durable, and functional products for nearly all environments. High Percentage of Open Area Typically ranging from 50 to 80 percent, allows for the unhindered passage of light, air, and liquids reducing costs for lighting, ventila-tion, and re suppression. High Strength-to-Weight Ratio Designed for maxi-mum ef ciency and capable of supporting loads ranging from light pedestrian traf c to the heaviest vehicular and aircraft loads. Product Flexibility Easily fabricated to suit the exact con guration of your application. Economy Commonly shop fabricated and nished to meet the speci c intricacies of each project. Once deliv-ered to the site and fastened in place the oor is immedi-ately ready for service.

3 Maintenance-Free The high percentage of open area allows for excellent drainage and the free passing of de-bris, thus creating a virtually maintenance-free The National Association of Architectural Metal Manufacturers consists of fi ve operating divisions, each focused on specifi c metal products for building and related applications. Each division develops and maintains technical standards for its products and actively promotes their use by design Metal Bar Grating Division of NAAMM publishes the only manuals for standard and heavy duty gratings which are recognized by ANSI, the American National Standards Institute. These ANSI/NAAMM standards are your guide in assuring that your Grating needs are satisfi ed by products of consistent quality and Pacifi c, an active NAAMM member in good standing, designs, manufactures and fabricates bar Grating in strict accordance with published NAAMM standards.

Manufactured by welding the bearing bar/cross bar intersection, typically with automated forge welding equipment.

6 Available in carbon steel and stainless steel. Swage Locked GratingPopular for the manufacture of aluminum , stainless steel, and close mesh gratings. Cross bars are inserted into pre-punched holes in the bearing bars and hydraulically deformed to lock the bars in Pressure Locked GratingAssembled by inserting pre-punched bearing and cross bars into an egg-crate confi guration and deforming the cross bars under intense hydraulic pressure. Available in all materials and ideal for architectural and ornamental GratingExceptionally durable Grating manufactured by riveting bearing bars and bent connecting bars at their contact points. Excellent for applications involving impact loads and repetitive traffi c MethodsMetal Bar Grating is the workhorse of the industrial fl ooring market and has served industry for decades. Strong and durable with an exceptional strength-to-weight ratio, metal bar Grating can be easily fabricated to nearly any confi guration.

7 The high percentage of open area makes bar Grating practically maintenance-free and all products are fully recyclable. Manufactured by assembling a series of equally spaced metal bars to connecting cross members, bar Grating is available in three popular materials; mild carbon steel, 6000 series aluminum , and 300 series stainless steels. Additionally, Grating Pacifi c has the capacity to produce gratings constructed with other specialty metal Bars Secures position of the bearing DepthRanges from 3/4" to 7" depending on anticipated BarsLoad carrying main Bar ThicknessRanges from 1/8" to 1/2" depending on anticipated Bar Spacing Measured from center-to-center of cross bars in 1" increments. Standard spacing is 4" on center with 2" spacing available on special Bar Spacing Measured from center-to-center of the bearing bars in 1/16" increments.

8 Standard spacing for industrial fl ooring is 19/16" (1-3/16") on center. Other popular spacings are 15/16", 11/16", 1/2", and 7/16" on Pacific Service. Quality. Reliability.

Achieved by welding a fl at bar, similar in size to the bearing bars, to the cut end, banding enhances safety and should always be specifi ed when gratings are designed to be can reduce impact stress by transferring load to adjacent bearing bars and should always be specifi ed when gratings are subject to vehicular loads. Further banding descriptions and details may be found on page Finished &Anodized AluminumPaintedSteelService LoadsThe load tables on the pages within this catalog provide load/defl ection criteria for most common applications.

10 These tables provide a concise reference allowing the specifying authority to select the appropriate bearing bar size and spacing for the intended application. Pedestrian loads are commonly analyzed with uniform and concentrated loads. For pedestrian comfort, defl ection is typically limited to 1/4".Heavy duty and vehicular load tables are presented for specifi c load conditions. Heavy duty load tables are presented with defl ection limited to the lesser of 1/8" or your application is not addressed by the load tables found in this catalog, please contact Grating Pacifi c for assistance selecting the product most appropriate for your Surface Standard surface with excellent self-cleaning characteristics.
