Inverted Seam® Patent

PATENT US 20070175157 A1

The Inverted Seam patent is used in a number of Zahner metal products. Primarily used for both roof and wall enclosures, these systems provide an advanced degree of protection from moisture. Inverted Seam roof systems can be installed at near-level pitches because of its sub-surface drainage channel, enabling architects to design for flat roof systems with a uniform metal appearance.

Patents

The Inverted Seam is a panel attachment system which includes the exterior panels, the retaining members, and mounting structures which secure the system. The panels are held to the retaining members through the use of protruding locking members formed on the panels which interlock with a slot formed on the retaining member. The panels may be coupled to the retaining members without the need for precise alignment, thereby expediting the installation of the surface. The retaining members additionally contain a drainage channel to carry water and other debris away from the surface.

ZEPPS™ Architectural Form Patents

PATENT US 20080196356 A1, 20060150571 A1, 7784243 B2, 7434366 B2

The ZEPPS patents are used in Zahner metal systems for producing forms in metal. Primarily used to create curving forms in metal, the ZEPPS process provides designers with a simple solution for developing curved building enclosures. A single ZEPPS assembly includes both the exterior and interior substrate, structure, and finished surface.

Forms created using ZEPPS technology include several components. An exterior surface is attached to a I-beam-shaped form with with D-shaped flanges. The outer surface of the D-shape is serrated to grip a wall panel or other structure attached to the flange and the inner surface includes ridges to strengthen the flange.

ZIRA ImageWall® Patent

US 7212688 B2

A method of transferring a representation of an image to a surface of a building. The method comprising receiving the image as an image file, converting the image file to a raster file comprising a series of dots, scaling the raster file to the surface and dividing the raster file into a plurality of sub-components, associating the dots with markings, and transferring the markings onto a plurality of metal sheets. The system is used by a number of Zahner products and systems, including ImageWall for custom perforated metal, Louvered ZIRA, and custom ZIRA applications.

The markings may be indentations, holes, and/or bumps. The dots may be manipulated to accommodate features of the surface, such as windows, doors, indicia, and edges of the sheets. The markings are preferably transferred to the sheets by a metal working machine. Thus, the method may include generating one or more control files that may be used by the machine.

ShopFloor® CloudWall Patents

US PATENT PENDING 14/735842 G06F17/50

A system and method for designing, visualizing, pricing, and generating specifications for custom building components to be installed onto a structural surface such as an outer wall of a building. The system may be a web server accessible by a web browser and having a computer program stored thereon for accessing information related to building components from a database.

The computer program may also receive from a user a selection of a type of building component to customize from the database, as well as surface parameters for the structural surface and user-selected parameters to be applied to a building component of the selected type. The computer program may display a visual depiction and a cost of the building component having the user-selected parameters. The computer program may also generate specifications for fabricating and installing the building component having the user-selected parameters.

Undulated Metal System Patent

PATENT US 20120258333 A1

Zahner patent for highly contoured metal building panel and its method of production. The patent relates to specific undulated metal panel systems offered by Zahner. A contoured metal building panel comprising an inner layer formed from a piece of flexible material that has been manipulated to create contours along its surface and an outer coating that substantially encases and hardens the flexible material so that the contours are substantially rigid and fixed.

One embodiment of the patent is by use of manipulating a piece of flexible screen-like material to create contours in the material; securing edges of the flexible material so as to substantially maintain the contours in the material. The material is either dipped in molten metal or painted with a hardening coating. The flexible material may be any material that can be manipulated into a desired shape. For example, the flexible material may be fiberglass screen material, aluminum screen wire material, copper screen wire material, bronze screen wire material, stainless steel screen wire material, or galvanized steel screen wire material.

Angel Hair® Zahner Patent

US 20100233942 A1

A patented fabrication system for producing Angel Hair non-directional finishes on metal surfaces. An apparatus for applying a lightly scratched surface to a metal sample comprises a motor, a disk, a frame, a motion guidance unit, and a plurality of springs. The motor may provide a rotational motion to the disk which includes abrasive elements configured to create a plurality of microscopic scratches on the surface of the metal sample.

Zahner Spring Chair Patent

PATENT US 20070188006 A1

Zahner-patented seating system featuring a continuous shape, able to painted and finished in a variety of metal surfaces and finishes. The chair appears both heavy and lightweight, providing people with a unique reclining seating system for interior and exterior applications.

The chair has a continuous surface, comprising a sheet of metal, which enables the chair to change shape without requiring the use of complex moving elements. The shape change is a reaction to the weight of a person seated in the chair, and creates an asymmetric rocking motion in reaction to shifts in the weight of the person.

ShopFloor® StoreFront System Patent

PATENT PENDING US 14/839507

An addition to the ShopFloor patented systems developed by Zahner. The patent includes a replaceable curtainwall system for metal coverings and window supports. System assembly includes aluminum framing, glass inset, and assorted exterior mullion cladding in a variety of metal surfaces.

Omni-Directional Connection Assembly Patent

A component addition for ZEPPS patented assemblies which provides universal omni-directional connections for panel attachment. The omni-directional connection assembly includes a hinge pin and one or more connection brackets.

Historic Patent for Sheet Metal Seaming Machine

PATENT US 2171297 A

A historic Zahner patent awarded in 1937 for improving speed of seaming sheet metal roof systems. The system provided a double-layer standing seam roof, at a rapid speed for producing massive roof systems.

The machine about the size and weight of a cast-iron bathtub, and was rolled around the roof to seam roofs on large-scale projects. The machine is no longer used. Zahner has since developed more efficient and effective roof systems for buildings.

Bold Batten Roof System Patent

PATENT US 5272849 A

The bold batten roof patent is a complete weathertight roof system with no exposed fasteners which prevents longitudinal movement between joints and covers. Previous fastener systems developed by architectural industry had issues with thermal expansion, in part due to the fastening system. This system solves these issues and others, providing a cleaner aesthetic for bold batten roofs.

An improved roof covering system includes roof panels, joint areas, joint covers, and securing assemblies. The joint covers include transversely extending locking tabs. The securing assembly includes clips having vertically oriented slots for engaging the tabs. The cover is thereby secured over the joint in weathertight relationship without the use of exposed fasteners while preventing longitudinal movement between the joints and covers.
