Project Overview:
The main design feature of the new Akron Art Museum is its “Roof Cloud” (high roof). The Roof Cloud hovers above the building, creating a blurred envelope for the museum. It encloses interior space, provides shade in exterior spaces and also operates as a horizontal landmark in the city. As part of the roof cloud system, Ohio Gratings, Inc., in conjunction with the architect provided a full depth egg crate style aluminum grid system that is supported by steel Uni-Struts welded to the cantilevered structural steel beams which extend from the core of the building. The system was refined to meet air flow and shade requirements and engineered to be as lightweight as possible. To meet the needs of the architect, Ohio Gratings Inc. developed an egg crate grid that is comprised of 2" x 1/8" aluminum bars pressure locked together at 3" x 6" openings. Ohio Gratings then fabricated panels at the same module as the metal wall panels that enclose the main gallery spaces. The grating panels themselves had to meet wind load criteria along the desired shading target, yet still be light enough as to not overwhelm the structural steel beam which cantilevered out to create the structure of the “roof clouds.” As a final step, the aluminum grid panel system was clear anodized with a class I finish. The panels were then attached and installed using a galvanized steel Uni-Strut system which was welded to the structural steel. The Uni-Struts allowed for installation of the panels in exact alignment despite greater than anticipated defections in the steel beams. 3D computer design software was used to model every panel and connection prior to fabrication and used updated models throughout the construction process. |

This project started back in November, 2004 when I was working with Joe
Holland with Hostettler Construction who was the General Contractor for
the Arundel Mills building. We initially quoted 19DT4 2 x 3/16” grating
for the sunscreen. The owner of the building liked the way the Dove
Tail looked and wanted to stay with steel.
In April of 2005 I got a call from Don Hobbs, President of Shenango of PA. He asked me about a job in Baltimore, MD where they needed grating for sunscreen. He faxed me an inquiry that was sent to him from Hostettler Construction. It was for 3750 SF of 19DT4 2-1/2 x 3/16 galvanized grating. I called Don up shortly after and asked him if we could change the material type over to aluminum to save weight and also save some money on freight. Over the next four months we changed from 19DT4 2-1/2 x 3/16” to 19ADT4 2-1/1/2 x 3/16 to 19SGI4 2-1/2 x 3/16” to finally 19SGLI4 2-1/2 x 3/16. We went from 67,000 lbs to 16,000 lbs. Customer was happy because he liked the style, it was extremely strong and for less then a third the weight, saved him $23,000 dollars over the initial material they selected. The owner has another building in the works that is a mirror image to the Arundel Mills building. Light I-Bar will be selected for the sunscreen again. |

The city of Auburn Hills requested they enclose the area around dumpsters.
CCC required a lightweight system that could provide 100% visual blockage as well as adequate airflow.
Based on these criteria, Ohio Gratings used their LG 100 aluminum louver and assisted with the design of
panel sizes and framing. 3”x5” aluminum angle frame was miter cut and welded to form the frames for each
unit to allow for effective mounting and sufficient strength as operable panels. The aluminum, provided
in mill finish, required minimal maintenance over time while retaining an attractive appearance.
Mounted to the galvanized steel structure, provided by CCC, will ensure that the enclosure is
long lasting and durable.

Project Overview:
Located on the rooftop of the headquarters of the American Society of Landscape Architects in the heart of Washington, D.C., the ASLA Green Roof project involves the transformation of an existing 3,000 square foot roof into a prime example of green roof technology. The barrel-shaped mounds at the north and south ends of the roof create new horizons for visitors, clearing the immediate urban foreground and focusing views on the surrounding Washington skyline. The roof was designed with the goals of allowing occupation by many people at once while also maximizing the green cover on the roof. To achieve this, the green roof system was initially designed to incorporate steel bar grating using a beamed structural support design. The intent of the design was to suspend the grating over plantings to take advantage of the open grid of the grating to expand the green roof surface. Chris Counts was the lead Architect from Michael Van Valkenburgh. For this application we recommended Aluminum I-Bar grating. Aluminum’s lightweight mass is only 1/3 that of steel reducing the overall weight of the grating on the roof by two thirds. Its strong strength to weight ratio easily handled the span and loading requirements. It’s corrosion resistance far outlasts galvanized steel and is naturally a much more attractive product. Because of inherent problems of plants growing up through the grating, causing a natural slippery surface when walked on, Slip-Not abrasive surface was selected to add adhesion. |

A twelve acre park which acts as a buffer between residential
neighborhoods and the regions largest shopping mall and is split by
Bear Creek, a tributary of the Ohio River. The creek is subject to
frequent flooding which extends into the adjacent residential areas.
The increased development in the area dramatically raised the storm
water run-off into the creek. The original design of the wetlands was
incorrectly graded, so when the preserve was redesigned the entire area
underwent a new topography change. An elevated walkway was designed for
the area, sprawling through the preserve. Wallace Roberts and Todd,
Landscape architects based out of Philadelphia, PA, were chosen for the
job. David Ostrich, Senior Associate of Wallace Roberts and Todd, had
used grating products in other projects they had done in the area and
needed material that was strong, environmentally friendly, allowed
light to filter through and was both ADA and high heel compliant. The
project ultimately used 3000 square feet of close mesh Steel Dove Tail
Grating with bearing bar at 7/16” on center, with a SlipNot finish
applied. The product used for this application:

We sent samples of our LG100 louver grating product and then the mounting system was designed. That system consisted of
aluminum ‘C’ channels, aluminum angle at the top to finish and aluminum angle at the bottom to hold the louver above the
concrete ledge. Installation also needed aluminum base plates welded to the bottom of each vertical post and some aluminum
angle to wrap over the edge of the concrete to mount securely. Since the parking garage was sloped in areas where our louver
was to be installed, we needed to adjust the louver panels and have them skew cut at the bottom to hold a horizontal look at
the top. The louvers were installed behind a wire mesh exterior treatment and were meant to keep residents of an adjacent
condominium from seeing automobile headlights moving in the garage. Additional louver grating may be needed along the front of the garage to hide the fact that it is a garage. |

This pedestrian bridge connects a parking garage owned by Delaware Department of Transportation, to an office building
with retail shopping outlets owned by Barclay’s Bank. Project included excavation of the retention pond and installation of a
pedestrian bridge. The original specifications for this project called for a Pressure-Locked Steel galvanized grating with 1-1/2" x 3/16" bearing bars, spaced at 7/16" centers, and bearing bars at 4" o/c, with an applied abrasive finish. We sent samples of our 7DT4 with an AlGrip surface and drawings of our anchor blocks mounted 1/4" below the surface of the grating. High-heel proof dovetail grating, anchor blocks and tek screws hold the grating in place and all end dimensions of grating lined up. |

Ever since his discovery in the Valley of the Kings, millions of people have rushed to view the boy king's treasure's.
Because of the high value of artifacts in the exhibit, strenuous security requirements had to be implemented. Among them,
a decision to add a second floor entrance to the museum would provide an extra dimension of security along with a new set of
stairs and landings. As one of the U.S. host cities for the exhibit, the Museum of Art was in a rush to get ready for King
Tut's arrival. Glavovic Studio contacted us to review products which could meet ADA standards for stairs and platforms, yet match their artistic requirments for the project. Our unique diagonal punch design aluminum punched plank with 15% open area with its light airy appearance was the ideal choice. The order needed to be processed and installed quickly. The order was placed on December 6th, shipped three days later, and installed well before the museum opened its doors on December 15th. Our ability to provide a superior product to meet the deliver and security requirements made our AIPlank 15 "Fit for a King." |

| The Main North Lofts building has retail space on the first level with residential housing and commercial office space in the floors above. Couturier Iron Craft was contracted to provide exterior balcony railings, interior railings and a unique building sign. Couturier worked with the architect to develop the idea to use light weight aluminum grating for the background of the sign. Ohio Gratings, Inc. provided the Swaged Aluminum for the background of the sign. Their grating was welded to structural aluminum material in which no fasteners were used. Aluminum letters and numbers were water jet cut out of aluminum plate. The letters were welded to the grating. The sign was finished and mounted to the side of the building. | |||||||||||||||

A typical steel structure support system. The platform and open walkway
requirements included multiple levels and stair treads.
A stair tower utilized galvanized treads with checker plate nosing because of the safe walking surface it provides. Galvanized grating and treads were used because it is strong, inexpensive and is quick fabricate which makes it readily available. Due to the typical longer spans and penetration requirements for pipe, etc., light duty galvanized steel grating was specified for this project. Light duty steel grating offers a high strength to weight ratio at a very economical cost. Cut outs for penetrations are accomplished either by steel fabrication or the grating manufacturer from project drawings and site measurements. |

| This product is used as a Roof Screen Wall. It utilized approximately 1400 square feet of our Louver Grate to screen mechanical units from the sidewalk. The Louver Grate was specified to be used with the louver “blade” pointing up. This is because the area to be screened is elevated from the sidewalk and if the louver is used in its standard orientation, the mechanical units would still be visible. | |||||||||||||||

fencing and gates near D-Street at the Lindbergh Terminal. It included
construction of new asphalt pavement, concrete curb, gutter and
sidewalk, aluminum bar grate fence, aluminum gate, vehicle crash gate,
chain link fence and vehicle drop arm gate. The architect and airport
commission were looking for an attractive fence fence design. We provided 6,800 sq. ft. of 15SGF 1" x 1/8" grating fabricated into fence panel. Approximately 911 lineal feet of panels and posts were provided. The fence was fabricated from 1-1/2" x 4" x 84" aluminum bar with a mounting pad. The gate was fabricated from 4" x 4" solid aluminum bar. |

This project utilizes our product in two similar, but somewhat different applications. The first is for the Handrail Infill. Our grating
gives the balconies a secure barrier and at the same time it is aesthetically pleasing. The second application is to fill open areas
at the parking level while still allowing air flow and maintaining a consistent appearance to the exterior of the building.

This bridge connects the island township to the city of Trenton, MI over the Trenton Channel.
Previously, the deck surface was converted over to welded steel bar grating. Over the past
several years, this welded steel grating provided by another manufacturer deteriorated. New
grating was provided by Ohio Gratings which is riveted galvanized steel grating and allowed
for this bridge improvement.
The overall project included new bridge decking, sidewalks and curbing, guardrails and extensive structural steel work below the bridge deck. The bridge was closed for improvements from May 2007 to mid December 2007. Our steel riveted grating which has bearing bars 5” x 3/8” and serrated connecting bars replaced the deteriorated welded steel grating. We also supplied a portion of the steel riveted grating with pans & rebar which were concrete filled. The concrete pan filled grating was located at each approach and at each end of the swing span. Aluminum plank was provided for the sidewalks in both directions has a diagonal punch pattern which meets ADA specifications and included a slip resistant aluminum surface. This aluminum plank replaced a deteriorating concrete surface. The Lite I-bar aluminum grating was installed under the bridge for an inspection walkway. Ohio Gratings has many grating products applicable for bridge decking surfaces and met with Wayne County Engineering early in the design stage to demonstrate our company’s products and services. Ohio Gratings engineering staff was invaluable with initial engineering & design support and project management throughout the project. Ohio Gratings shipped 22 truckloads of material over this eight month long project. |

The building was a Hudson Belk department store and was being refurbished as a first floor retail store.
The grating was used to cover up dryer and toilet vents on the side of the building. To give the appearance
of a one-piece construction the material was supplied in units which had to be extended across rods and the
aluminum grating gave the building a nice sheen appearance. These units were then placed against the side
of the exterior of the building.

This project was to create a riverfront plaza on the Detroit River,
which is part of a citywide project to redevelop the city riverfront.
When completed it will transform over a mile of the Detroit Riverfront
into walkways, parks, bicycle paths, and open green areas. Plaza includes new landscaping, hand rails, walkways, benches, and a large granite area with a world map displayed featuring different color grating for each country. The project included stainless steel and aluminum grating for a water fountain and trench covers. The fountains consisted of 1,100 sq ft. of stainless steel metal bar grating and has a 7/16" center to center spacing. The 534 pieces of grating includes a center hole cut out in which a stainless steel escutcheon plate and nozzle assembly was inserted. The grating pieces were fastened down to the stainless steel fram system using a countersunk land design. Lights were then installed underneath the grating. The fountain is also surrounded by decorative brick paving blocks. |

Along the waterway and across from the newly constructed Museum of Glass, our
new Wheels n’ Heels product was the perfect solution.
By the marina along the wide shoreline promenade, an area was needed to allow light penetration under the walk way to meet the National Marine Fishing Specifications. Officials decided to go with our new heavy duty Wheels n’ Heels product at the suggestion of Grating Pacific, our distributor on the west coast. Because of the many public functions, the product needed to meet AASHTO and ADA requirements. This area accommodates pedestrians, bicyclists, roller bladers and public events including concerts. In addition, because of the nature of the project, the material needed to be architecturally pleasing as well. Our new product fit the bill by using a swaged steel panel and integrating it with our traditional heavy duty steel grating. It allows us to provide a wider and longer more architecturally pleasing product which worked perfectly for this project. Advantages of our current Wheels n’ Heels grating include:

The church had a plywood handicapped access ramp which was in poor condition
and needed to be replaced. They needed something with a non-slip surface
(Slip-Not), with ADA compliancy. The ramp was approximately 30 feet x 4’ span.
A landing area in front of the main door would need significant fabrication
to fit correctly.
Since there is an aggressive striated surface on the plank, it provides significant drainage and ADA compliancy is achieved. |

| The architect on this project was
looking for a security fence that would act as a barrier/screen
and allow air flow through the material into the areas behind.
We supplied our standard space electro forge carbon steel grating
with a mill finish as infill to install into our customer’s
framing. The structure was assembled and then painted as one unit.
Since the fence was being used on a college campus, it needed to
have a nice aesthetic appeal from the road. |

The 1001 Woodward Avenue project included renovation of an unoccupied
downtown Detroit office building into residential lofts. The project
also included construction of a new ten story precast concrete parking
structure next to the existing building for residential parking. The architectural drawings specified a wire mesh infill for the area between parking levels with an option for an aluminum architectural grill with an anodized finish. The owner chose the more expensive aluminum architectural grill option to achieve an overall better appearance for the parking structure. The entire 1001 Woodward Avenue parking structure project was completed in December 2005. The parking structure was in the center of Super Bowl XL activities in Downtown Detroit. |
