Projects
From the prestigious Getty museum to small town water treatment plants; from huge industrial projects to two foot grating tiles, we've provided innovative grating solutions, personal service, and rock solid products. Here are a few of our more memorable projects:
 
J. Paul Getty Museum
For this exceptionally high profile project, renowned architects, Richard Meier & Partners and well-known general contractor, Dinwiddie Construction Company, demanded exceptional construction quality. Seidelhuber was specifically selected as the exclusive grating supplier for all grating throughout the entire Museum. Richard Meier & Partners also specified only Seidelhuber for work on the San Jose Civic Center. In general, architects with high-visibility applications prefer Seidelhuber because of the workmanship.
 
Caldecott Tunnel (Berkeley- Orinda CA)
Used for the Bay Area Rapid Transit system, this pair of tunnels runs a total of 9 miles. For this large project, we built the catwalk grating for escape in the event of a subway breakdown or emergency.
 
Dixon City Water Treatment Plant
We're happy to handle small projects too. This project demanded only a 2 foot by 2 foot grating. Small jobs have to be finished also.
 
Applied Materials
The leading capital equipment manufacturer for the semiconductor industry had a troubling failure of its steel cleanroom raised floor gratings. The floor tiles were buckling under the weight of heavy tooling which was rolled across the raised floor panels.

We designed and built replacement floor tiles, which would support up to 3,000 pounds of rolling load on a 1" square anywhere on the grating with less than 0.1" deflection. Our grating passed Applied Material's critical tests and we became the exclusive supplier for Applied Materials replacement tiles with this problem.

 
The Boeing Company
We built the platforms Boeing uses to paint its aircraft. This was a complex aluminum fabrication challenge because the grating hugs the curved side of the aircraft fuselage. This involves compound angles. The fuselage and the edge of the grating curved along the length of the fuselage, front to back, and along the circumference, top to bottom. Grating planes were never horizontal, compounding dimensional control. In general, architects with high-visibility applications prefer Seidelhuber because of the workmanship.
 
Hewlett-Packard Company
HP had numerous CNC machines that sprayed oil creating a slippery floor and a safety hazard. We built grating and applied our anti-slip surface, Safety Grit.
 
Major Microprocessor Manufacturer
One of the world's largest chip makers and a leading manufacturer of computer, networking, and communications products, uses a unique product designed specifically for its use. We designed grating to be used in front of critical manufacturing equipment and ovens, converting expensive stainless steel grating to aluminum grating while preserving the strength and reducing the cost by half.
 
Motorola
For Motorola cleanrooms, we've provided thousands and thousands of raised floor tiles early in the microprocessor development.
 
Seagate
We provided specially designed raised floor tiles for a unique, custom-sized application. Panel dimensions greater than 2 foot by 2 foot were required and our application solved this dilemma perfectly.
 
DisneyLand
Disney is exceptionally fussy regarding their vendors and the quality of products introduced into its amusement properties. Over many years, we've provided grating for many Disney rides and displays, especially those involving water and drainage in high public use areas.
 
Hollywood Bowl
The Hollywood Bowl, the largest natural amphitheater in the United States, is well known for its clam shell theater backdrop and famous outdoor concerts. We designed and built grating for cable trenches. These trenches ran extensively in areas with heavy audience foot traffic. Their goal was to cover and conceal these trenches. We built a unique banding design with a 3/8" recess to allow for carpet to be placed inside of the tile. When installed, all that shows is carpeting and a thin line of banding.
 
The Gap, Embarcadero Center San Francisco
We provided a close mesh bronze grating, covering the huge plaza area in front of The Gap store at the landmark Embarcadero Center. Unlike a cast bronze, swaged bronze grating has a cleaner look, with sharp, parallel lines. The aging process will ultimately result in a natural statuary bronze finish. The close mesh is high-heel friendly.
 
PG&E
The gas and electric provider for all of Northern California, PG&E elected to install only underground transformers. We built 10,000s of underground vaults. We designed a vault with a sidewalk-level grating on top. Our design permitted ventilation and included a unique adjustment kit to allow for variations in the ground grade. We used a combination of I-Bar grating and solid open K grating.

Used in extensively in newly built residential neighborhoods, the grating had to be ADA compliant, meet load requirements, be slip resistant, and - to prevent electrocution - "poke proof." To make our grating "poke proof," we developed a louvered grille that allowed a 0.5" ball to drop through the grating but prevents a stick or a rod from touching the dangerous transformer and cables, possibly electrocuting a curious child.

 
US Navy
For 15 years, we've provided aluminum plank grating and deck track to the US Navy. Our grating is in use on half of the US fleet. Based on Navy designs, we fabricate two types of naval grating. The first is for use in freezers: holes in the grating are used to hold telescopic poles battens (or pogo sticks) positioned floor to ceiling to batten down freezer cargo and prevent cargo from sliding as the ship rocks back and forth on the high seas. The grating allows for water drainage in the freezers. Also manufactured is deck track; we locate holes on exact locations. Heavy battens with mechanical locks are positioned to matching holes in the overhead and deck to batten down heavy equipment, cargo, and ammunition. We have deck track in ALL of the navy's Ordinance Transports.
 
Waljeski Residence
David Lawrence Gray designed the award-winning Waljeski Residence in Malibu, California. After the devastating Malibu fires of 1993, Gray designed this house to survive future fires. Using concrete, glass, and steel, the residence has won two prestigious awards - Concrete Excellence Award and Concrete Reinforcing Steel Institute Design Award. We fabricated exquisite grating for use in a wide variety of applications, such as sun screens, catwalks, sun decks and hand railings, for this beautiful home.
