A self-aligning, double wire corner bead for fireproofing structural steel along a plurality of surfaces, the corner bead having a single strip of welded wire fabric cut to a predetermined width for the fireproofing thickness and bent along a plurality of longitudinally extending lines, to provide a profile having a plurality of dihedral angles is disclosed. A nose is installed along two edges. A method of finishing the corners for fireproofing of structural steel member using an improved corner bead includes the step of attaching the corner bead through a lath to the structural steel member utilizing fasteners. The mesh of the corner bead provides a dam to form a roughened surface on the first application of fireproofing material until it hardens.

A sandwich structure employs a core sheet including alternating peaks and valleys therein, and at least one outer face sheet including grooves or ribs therein. In another aspect, a sandwich structure includes at least one core and at least one adhesively bonded outer face sheet including elongated grooves or ribs formed therein. Yet another aspect of a sandwich structure has raised ridges bridging between adjacent peaks in a core sheet in one direction but not in a perpendicular direction, which synergistically interface, engage or contact with grooves or ribs formed in an outer face sheet.

A metal/polymer composite material is disclosed, wherein the metal/polymer composite material comprises a polymer base and a metal heat-dissipation layer. The heat-dissipation layer comprises a roughed surface with an isotropic surface roughness. The metal heat-dissipation conformally blankets over the roughed surface.

Disclosed is a metal sheet having a first major surface and an opposite second major surface, a first end and an opposite second end, and a first side edge and an opposite second side edge. The sheet has a plurality of parallel corrugations having a length defining a first axis extending along the sheet, a width defining a second axis extending across the sheet, and a depth defining a third axis extending through the sheet. The corrugations are formed by roll forming of the metal sheet. In transverse cross section, each of the corrugations comprises a substantially convex portion and a substantially concave portion. The substantially convex and concave portions each comprise a plurality of substantially linear portions with curved transition portions therebetween. The curved transition portions have a radius sufficiently small to cause plastic deformation of the metal sheet during roll forming of the corrugations. The substantially convex and concave portions each approximate a smooth curve.

The present invention provides a deformed part created by forming a coated metal sheet into a part, the coated metal sheet comprising a steel substrate, at least one face of which is coated with a metal coating deposited by dipping the substrate in a bath, said coating comprising between 0.2 and 0.7% by weight of Al, the remainder of the metal coating being Zn and inevitable impurities, wherein an outer surface of a metal coating of the deformed part has a waviness Wa0.8 of less than or equal to 0.43 ?m.

A method of forming a pair of opposed side walls and a pair of opposed end walls of a sheet metal casket shell from a single piece of sheet metal. The piece of sheet metal has opposite ends and a length equal to the combined length of the pair of side walls and the pair of end walls of the casket shell to be formed. The opposite ends of the piece of sheet metal are secured together to form a tube. A roll forming roller is positioned in an interior of the tube. A female die configured to produce a desired profile for the side walls and the end walls of the casket shell is positioned around an exterior of the tube. The roller is moved outwardly so as to contact an interior surface of the tube and deform the tube toward a die cavity of the female die. The roller is rolled around a perimeter of the interior of the tube so as to deform the perimeter of the tube toward the die cavity of the female die. The desired profile for the side walls and the end walls of the casket shell is thereby produced.

A self-aligning corner bead for fireproofing structural steel, having a strip of welded wire fabric cut to the appropriate width for the fireproofing thickness and bent longitudinally to form an obtuse V-shaped device is disclosed. A plastic nosing is installed along one edge. A method of finishing the corners for fireproofing of structural steel member using an improved corner bead includes the step of attaching the first wing of an obtuse V-shaped device through a lathe to the structural steel member utilizing pneumatic or screw type fasteners. The mesh structure of the second wing of the V-shaped device provides a dam to form a roughened surface on the first application of fireproofing material until it hardens.

In particular embodiments, the present disclosure provides targets including a metal layer and defining a hollow inner surface. The hollow inner surface has an internal apex. The distance between at least two opposing points of the internal apex is less than about 15 m. In particular examples, the distance is less than about 1 m. Particular implementations of the targets are free standing. The targets have a number of disclosed shaped, including cones, pyramids, hemispheres, and capped structures. The present disclosure also provides arrays of such targets. Also provided are methods of forming targets, such as the disclosed targets, using lithographic techniques, such as photolithographic techniques. In particular examples, a target mold is formed from a silicon wafer and then one or more sides of the mold are coated with a target material, such as one or more metals.
