A method for manufacturing an architectural panel and an architectural panel made by the method. The architectural panel may be formed from metal, and the method may start with the processing of a flat metal sheet. The method may include punching holes in a particular pattern into the flat metal sheet, bending the flat metal sheet into a particular shape to form a panel that can be hung from an overhead grid or the like, and printing a desired printing pattern onto the panel. The method may also include a step of coating the panel with a powder coating or a liquid-applied paint finish prior to the printing step. The coating step may occur after the punching step and before the printing step.

A method of fabricating a conduit comprises steps of attaching a first tubular-outboard-ply end of a tubular outboard ply to a first inner collar portion of a first collar with a third weld and attaching a second tubular-outboard-ply end to a second inner collar portion of a second collar with a fifth weld. The method additionally comprises steps of interconnecting the first inner collar portion and a first outer collar portion of the first collar with a first weld and interconnecting the second inner collar portion and a second outer collar portion of the second collar with a sixth weld. The method also comprises attaching a trimmed first corrugated-inboard-ply end to the first outer collar portion with a second weld, attaching a trimmed second corrugated-inboard-ply end to the second outer collar portion with a fourth weld, and communicatively coupling a first sensor with an interstitial space.

A production method for a steel component includes preparing a patchwork material including steel sheets that are laid one on another, at least one of overlap surfaces of the steel sheets including a zinc-based plating layer, heating the patchwork material, and performing hot stamping on the patchwork material heated to form the steel component in which a joint part between the steel sheets is disposed in a bent area. When t.sub.out denotes a sheet thickness of a steel sheet located on an outer side in the bent area, and t.sub.in denotes a sheet thickness of a steel sheet located on an inner side, t.sub.out/t.sub.in≥1.1 is satisfied. The joint part is disposed in a ridge portion or at a position in a vicinity of the ridge portion, and the position satisfies d/t.sub.in<8.2, where d denotes a distance from the ridge portion to the joint part.

A method for obtaining a three-dimensional curve in a tubular product starting from a tube extending along a rectilinear longitudinal axis includes performing, by a first bending device, a first bending operation on a bending plane passing through the rectilinear longitudinal axis (x), so that the tube leaving the first bending device has a curved portion lying on the plane of curvature, and performing on the tube leaving the first bending device, by a second bending device, a second bending operation, so that the curved portion of the tube at the output of the second bending device has a first tangent and a second tangent (t1, t2) at its opposite ends lying on a cylindrical surface having generatrices orthogonal to two planes (A1, A2) respectively containing the first and second tangents (t1, t2). A method for manufacturing complex-curvature tubular products is also provided.
